AI and ML perspective: Performance optimization

This document in the Well-Architected Framework: AI and ML perspective provides an overview of principles and recommendations to help you to optimize the performance of your AI and ML workloads on Google Cloud. The recommendations in this document align with the performance optimization pillar of the Google Cloud Well-Architected Framework.

AI and ML systems enable new automation and decision-making capabilities for your organization. The performance of these systems can directly affect your business drivers like revenue, costs, and customer satisfaction. To realize the full potential of your AI and ML systems, you need to optimize their performance based on your business goals and technical requirements. The performance optimization process often involves certain trade-offs. For example, a design choice that provides the required performance might lead to higher costs. The recommendations in this document prioritize performance over other considerations like costs.

Translate business goals to performance objectives

To make architectural decisions that optimize performance, start with a clear set of business goals. Design AI and ML systems that provide the technical performance that's required to support your business goals and priorities. Your technical teams must understand the mapping between performance objectives and business goals.

Consider the following recommendations:

Translate business objectives into technical requirements: Translate the business objectives of your AI and ML systems into specific technical performance requirements and assess the effects of not meeting the requirements. For example, for an application that predicts customer churn, the ML model should perform well on standard metrics, like accuracy and recall, and the application should meet operational requirements like low latency.

Monitor performance at all stages of the model lifecycle: During experimentation and training after model deployment, monitor your key performance indicators (KPIs) and observe any deviations from business objectives.

Automate evaluation to make it reproducible and standardized: With a standardized and comparable platform and methodology for experiment evaluation, your engineers can increase the pace of performance improvement.

Run and track frequent experiments

To transform innovation and creativity into performance improvements, you need a culture and a platform that supports experimentation. Performance improvement is an ongoing process because AI and ML technologies are developing continuously and quickly. To maintain a fast-paced, iterative process, you need to separate the experimentation space from your training and serving platforms. A standardized and robust experimentation process is important.

Consider the following recommendations:

Build an experimentation environment: Performance improvements require a dedicated, powerful, and interactive environment that supports the experimentation and collaborative development of ML pipelines.

Embed experimentation as a culture: Run experiments before any production deployment. Release new versions iteratively and always collect performance data. Experiment with different data types, feature transformations, algorithms, and hyperparameters.

Build and automate training and serving services

Training and serving AI models are core components of your AI services. You need robust platforms and practices that support fast and reliable creation, deployment, and serving of AI models. Invest time and effort to create foundational platforms for your core AI training and serving tasks. These foundational platforms help to reduce time and effort for your teams and improve the quality of outputs in the medium and long term.

Consider the following recommendations:

Use AI-specialized components of a training service: Such components include high-performance compute and MLOps components like feature stores, model registries, metadata stores, and model performance-evaluation services.

Use AI-specialized components of a prediction service: Such components provide high-performance and scalable resources, support feature monitoring, and enable model performance monitoring. To prevent and manage performance degradation, implement reliable deployment and rollback strategies.

Match design choices to performance requirements

When you make design choices to improve performance, carefully assess whether the choices support your business requirements or are wasteful and counterproductive. To choose the appropriate infrastructure, models, or configurations, identify performance bottlenecks and assess how they're linked to your performance measures. For example, even on very powerful GPU accelerators, your training tasks can experience performance bottlenecks due to data I/O issues from the storage layer or due to performance limitations of the model itself.

Consider the following recommendations:

Optimize hardware consumption based on performance goals: To train and serve ML models that meet your performance requirements, you need to optimize infrastructure at the compute, storage, and network layers. You must measure and understand the variables that affect your performance goals. These variables are different for training and inference.

Focus on workload-specific requirements: Focus your performance optimization efforts on the unique requirements of your AI and ML workloads. Rely on managed services for the performance of the underlying infrastructure.

Choose appropriate training strategies: Several pre-trained and foundational models are available, and more such models are released often. Choose a training strategy that can deliver optimal performance for your task. Decide whether you should build your own model, tune a pre-trained model on your data, or use a pre-trained model API.

Recognize that performance-optimization strategies can have diminishing returns: When a particular performance-optimization strategy doesn't provide incremental business value that's measurable, stop pursuing that strategy.

Link performance metrics to design and configuration choices

To innovate, troubleshoot, and investigate performance issues, establish a clear link between design choices and performance outcomes. In addition to experimentation, you must reliably record the lineage of your assets, deployments, model outputs, and the configurations and inputs that produced the outputs.

Consider the following recommendations:

Build a data and model lineage system: All of your deployed assets and their performance metrics must be linked back to the data, configurations, code, and the choices that resulted in the deployed systems. In addition, model outputs must be linked to specific model versions and how the outputs were produced.

Use explainability tools to improve model performance: Adopt and standardize tools and benchmarks for model exploration and explainability. These tools help your ML engineers understand model behavior and improve performance or remove biases.

Reduce tuning costs

To help reduce the need for extensive data and compute time, fine-tune your pre-trained models on specific datasets. We recommend the following approaches:


Learning transfer: Use the knowledge from a pre-trained model for a new task, instead of starting from scratch. This approach requires less data and compute time, which helps to reduce costs.

Adapter tuning (parameter-efficient tuning): Adapt models to new tasks or domains without full fine-tuning. This approach requires significantly lower computational resources and a smaller dataset.

Supervised fine tuning: Adapt model behavior with a labeled dataset. This approach simplifies the management of the underlying infrastructure and the development effort that's required for a custom training job.

Explore and experiment by using Vertex AI Studio

Vertex AI Studio lets you rapidly test, prototype, and deploy generative AI applications.


Integration with Model Garden: Provides quick access to the latest models and lets you efficiently deploy the models to save time and costs.

Unified access to specialized models: Consolidates access to a wide range of pre-trained models and APIs, including those for chat, text, media, translation, and speech. This unified access can help you reduce the time spent searching for and integrating individual services.

Use managed services to train or serve models

Managed services can help reduce the cost of model training and simplify the infrastructure management, which lets you focus on model development and optimization. This approach can result in significant cost benefits and increased efficiency.


Reduce operational overhead

To reduce the complexity and cost of infrastructure management, use managed services such as the following:


Vertex AI training provides a fully managed environment for training your models at scale. You can choose from various prebuilt containers with popular ML frameworks or use your own custom containers. Google Cloud handles infrastructure provisioning, scaling, and maintenance, so you incur lower operational overhead.

Vertex AI predictions handles infrastructure scaling, load balancing, and request routing. You get high availability and performance without manual intervention.

Ray on Vertex AI provides a fully managed Ray cluster. You can use the cluster to run complex custom AI workloads that perform many computations (hyperparameter tuning, model fine-tuning, distributed model training, and reinforcement learning from human feedback) without the need to manage your own infrastructure.

Use managed services to optimize resource utilization


Optimize resource allocation


To achieve cost efficiency for your AI and ML workloads in Google Cloud, you must optimize resource allocation. To help you avoid unnecessary expenses and ensure that your workloads have the resources that they need to perform optimally, align resource allocation with the needs of your workloads.

To optimize the allocation of cloud resources to AI and ML workloads, consider the following recommendations.


Use autoscaling to dynamically adjust resources

Use Google Cloud services that support autoscaling, which automatically adjusts resource allocation to match the current demand. Autoscaling provides the following benefits:


Cost and performance optimization: You avoid paying for idle resources. At the same time, autoscaling ensures that your systems have the necessary resources to perform optimally, even at peak load.

Improved efficiency: You free up your team to focus on other tasks.

Increased agility: You can respond quickly to changing demands and maintain high availability for your applications.

The following table summarizes the techniques that you can use to implement autoscaling for different stages of your AI projects.


Training

Use managed services like Vertex AI or GKE, which offer built-in autoscaling capabilities for training jobs.

Configure autoscaling policies to scale the number of training instances based on metrics like CPU utilization, memory usage, and job queue length.

Use custom scaling metrics to fine-tune autoscaling behavior for your specific workloads.


Inference

Deploy your models on scalable platforms like Vertex AI Prediction, GPUs on GKE, or TPUs on GKE.

Use autoscaling features to adjust the number of replicas based on metrics like request rate, latency, and resource utilization.

Implement load balancing to distribute traffic evenly across replicas and ensure high availability.


Start with small models and datasets

To help reduce costs, test ML hypotheses at a small scale when possible and use an iterative approach. This approach, with smaller models and datasets, provides the following benefits:


Reduced costs from the start: Less compute power, storage, and processing time can result in lower costs during the initial experimentation and development phases.

Faster iteration: Less training time is required, which lets you iterate faster, explore alternative approaches, and identify promising directions more efficiently.

Reduced complexity: Simpler debugging, analysis, and interpretation of results, which leads to faster development cycles.

Efficient resource utilization: Reduced chance of over-provisioning resources. You provision only the resources that are necessary for the current workload.



Consider the following recommendations:


Use sample data first: Train your models on a representative subset of your data. This approach lets you assess the model's performance and identify potential issues without processing the entire dataset.

Experiment by using notebooks: Start with smaller instances and scale as needed. You can use Vertex AI Workbench, a managed Jupyter notebook environment that's well suited for experimentation with different model architectures and datasets.

Start with simpler or pre-trained models: Use Vertex AI Model Garden to discover and explore the pre-trained models. Such models require fewer computational resources. Gradually increase the complexity as needed based on performance requirements.


Use pre-trained models for tasks like image classification and natural language processing. To save on training costs, you can fine-tune the models on smaller datasets initially.

Use BigQuery ML for structured data. BigQuery ML lets you create and deploy models directly within BigQuery. This approach can be cost-effective for initial experimentation, because you can take advantage of the pay-per-query pricing model for BigQuery.

Scale for resource optimization: Use Google Cloud's flexible infrastructure to scale resources as needed. Start with smaller instances and adjust their size or number when necessary.


Discover resource requirements through experimentation

Resource requirements for AI and ML workloads can vary significantly. To optimize resource allocation and costs, you must understand the specific needs of your workloads through systematic experimentation. To identify the most efficient configuration for your models, test different configurations and analyze their performance. Then, based on the requirements, right-size the resources that you used for training and serving.


We recommend the following approach for experimentation:


Start with a baseline: Begin with a baseline configuration based on your initial estimates of the workload requirements. To create a baseline, you can use the cost estimator for new workloads or use an existing billing report. For more information, see Unlock the true cost of enterprise AI on Google Cloud.

Understand your quotas: Before launching extensive experiments, familiarize yourself with your Google Cloud project quotas for the resources and APIs that you plan to use. The quotas determine the range of configurations that you can realistically test. By becoming familiar with quotas, you can work within the available resource limits during the experimentation phase.

Experiment systematically: Adjust parameters like the number of CPUs, amount of memory, number and type of GPUs and TPUs, and storage capacity. Vertex AI training and Vertex AI predictions let you experiment with different machine types and configurations.


Monitor utilization, cost, and performance: Track the resource utilization, cost, and key performance metrics such as training time, inference latency, and model accuracy, for each configuration that you experiment with.


To track resource utilization and performance metrics, you can use the Vertex AI console.

To collect and analyze detailed performance metrics, use Cloud Monitoring.

To view costs, use Cloud Billing reports and Cloud Monitoring dashboards.

To identify performance bottlenecks in your models and optimize resource utilization, use profiling tools like Vertex AI TensorBoard.



Implement the data governance framework

Google Cloud provides the following services and tools to help you implement a robust data governance framework:


Dataplex Universal Catalog is an intelligent data fabric that helps you unify distributed data and automate data governance without the need to consolidate data sets in one place. This helps to reduce the cost to distribute and maintain data, facilitate data discovery, and promote reuse.


To organize data, use Dataplex Universal Catalog abstractions and set up logical data lakes and zones.

To administer access to data lakes and zones, use Google Groups and Dataplex Universal Catalog roles.

To streamline data quality processes, enable auto data quality.

Dataplex Universal Catalog is also a fully managed and scalable metadata management service. The catalog provides a foundation that ensures that data assets are accessible and reusable.


Metadata from the supported Google Cloud sources is automatically ingested into the universal catalog. For data sources outside of Google Cloud, create custom entries.

To improve the discoverability and management of data assets, enrich technical metadata with business metadata by using aspects.

Ensure that data scientists and ML practitioners have sufficient permissions to access Dataplex Universal Catalog and use the search function.


Expand reusability beyond pipelines

Look for opportunities to expand reusability beyond training pipelines. The following are examples of Google Cloud capabilities that let you reuse ML features, datasets, models, and code.

Ensure that AI and ML projects are aligned with strategic objectives like revenue growth, cost reduction, customer satisfaction, and efficiency. Engage stakeholders to understand the business priorities. Define AI and ML objectives that are specific, measurable, attainable, relevant, and time-bound (SMART). For example, a SMART objective is: "Reduce chat handling time for customer support by 15% in 6 months by using an AI chatbot".


To make progress towards your business goals and to measure the return on investment (ROI), define KPIs for the following categories of metrics:


Costs for training, inference, storage, and network resources, including specific unit costs (such as the cost per inference, data point, or task). These metrics help you gain insights into efficiency and cost optimization opportunities. You can track these costs by using Cloud Billing reports and Cloud Monitoring dashboards.


Project-specific metrics. You can track these metrics by using Vertex AI Experiments and evaluation.


Predictive AI: measure accuracy and precision

Generative AI: measure adoption, satisfaction, and content quality

Computer vision AI: measure accuracy


To validate your ROI hypotheses, start with pilot projects and use the following iterative optimization cycle:


Monitor continuously and analyze data: Monitor KPIs and costs to identify deviations and opportunities for optimization.

Make data-driven adjustments: Optimize strategies, models, infrastructure, and resource allocation based on data insights.

Refine iteratively: Adapt business objectives and KPIs based on the things you learned and the evolving business needs. This iteration helps you maintain relevance and strategic alignment.

Establish a feedback loop: Review performance, costs, and value with stakeholders to inform ongoing optimization and future project planning.



Use Cloud Monitoring to collect metrics from various sources, including your applications, infrastructure, and Google Cloud services like Compute Engine, Google Kubernetes Engine (GKE), and Cloud Run functions. To visualize metrics and logs in real time, you can use the prebuilt Cloud Monitoring dashboard or create custom dashboards. Custom dashboards let you define and add metrics to track specific aspects of your systems, like model performance, API calls, or business-level KPIs.


Use Cloud Logging for centralized collection and storage of logs from your applications, systems, and Google Cloud services. Use the logs for the following purposes:


Track costs and utilization of resources like CPU, memory, storage, and network.

Identify cases of over-provisioning (where resources aren't fully utilized) and under-provisioning (where there are insufficient resources). Over-provisioning results in unnecessary costs. Under-provisioning slows training times and might cause performance issues.

Identify idle or underutilized resources, such as VMs and GPUs, and take steps to shut down or rightsize them to optimize costs.

Identify cost spikes to detect sudden and unexpected increases in resource usage or costs.

Use Looker or Looker Studio to create interactive dashboards and reports. Connect the dashboards and reports to various data sources, including BigQuery and Cloud Monitoring.


Optimize resource allocation

Cost and performance optimization: You avoid paying for idle resources. At the same time, autoscaling ensures that your systems have the necessary resources to perform optimally, even at peak load.

Improved efficiency: You free up your team to focus on other tasks.

Increased agility: You can respond quickly to changing demands and maintain high availability for your applications.

The following table summarizes the techniques that you can use to implement autoscaling for different stages of your AI projects.



AI and ML perspective: Reliability

This document in the Well-Architected Framework: AI and ML perspective provides an overview of the principles and recommendations to design and operate reliable AI and ML systems on Google Cloud. It explores how to integrate advanced reliability practices and observability into your architectural blueprints. The recommendations in this document align with the reliability pillar of the Google Cloud Well-Architected Framework.


By architecting for scalability and availability, you enable your applications to handle varying levels of demand without service disruptions or performance degradation. This means that your AI services are still available to users during infrastructure outages and when traffic is very high.


Consider the following recommendations:


Design your AI systems with automatic and dynamic scaling capabilities to handle fluctuations in demand. This helps to ensure optimal performance, even during traffic spikes.

Manage resources proactively and anticipate future needs through load testing and performance monitoring. Use historical data and predictive analytics to make informed decisions about resource allocation.

Design for high availability and fault tolerance by adopting the multi-zone and multi-region deployment archetypes in Google Cloud and by implementing redundancy and replication.

Distribute incoming traffic across multiple instances of your AI and ML services and endpoints. Load balancing helps to prevent any single instance from being overloaded and helps to ensure consistent performance and availability.


Use a modular and loosely coupled architecture

To make your AI systems resilient to failures in individual components, use a modular architecture. For example, design the data processing and data validation components as separate modules. When a particular component fails, the modular architecture helps to minimize downtime and lets your teams develop and deploy fixes faster.


Consider the following recommendations:


Separate your AI and ML system into small self-contained modules or components. This approach promotes code reusability, simplifies testing and maintenance, and lets you develop and deploy individual components independently.

Design the loosely coupled modules with well-defined interfaces. This approach minimizes dependencies, and it lets you make independent updates and changes without impacting the entire system.

Plan for graceful degradation. When a component fails, the other parts of the system must continue to provide an adequate level of functionality.

Use APIs to create clear boundaries between modules and to hide the module-level implementation details. This approach lets you update or replace individual components without affecting interactions with other parts of the system.


Build an automated MLOps platform

With an automated MLOps platform, the stages and outputs of your model lifecycle are more reliable. By promoting consistency, loose coupling, and modularity, and by expressing operations and infrastructure as code, you remove fragile manual steps and maintain AI and ML systems that are more robust and reliable.


Consider the following recommendations:


Automate the model development lifecycle, from data preparation and validation to model training, evaluation, deployment, and monitoring.

Manage your infrastructure as code (IaC). This approach enables efficient version control, quick rollbacks when necessary, and repeatable deployments.

Validate that your models behave as expected with relevant data. Automate performance monitoring of your models, and build appropriate alerts for unexpected outputs.

Validate the inputs and outputs of your AI and ML pipelines. For example, validate data, configurations, command arguments, files, and predictions. Configure alerts for unexpected or unallowed values.

Adopt a managed version-control strategy for your model endpoints. This kind of strategy enables incremental releases and quick recovery in the event of problems.


Maintain trust and control through data and model governance

The reliability of AI and ML systems depends on the trust and governance capabilities of your data and models. AI outputs can fail to meet expectations in silent ways. For example, the outputs might be formally consistent but they might be incorrect or unwanted. By implementing traceability and strong governance, you can ensure that the outputs are reliable and trustworthy.


Consider the following recommendations:


Use a data and model catalog to track and manage your assets effectively. To facilitate tracing and audits, maintain a comprehensive record of data and model versions throughout the lifecycle.

Implement strict access controls and audit trails to protect sensitive data and models.

Address the critical issue of bias in AI, particularly in generative AI applications. To build trust, strive for transparency and explainability in model outputs.

Automate the generation of feature statistics and implement anomaly detection to proactively identify data issues. To ensure model reliability, establish mechanisms to detect and mitigate the impact of changes in data distributions.




Implement holistic AI and ML observability and reliability practices

To continuously improve your AI operations, you need to define meaningful reliability goals and measure progress. Observability is a foundational element of reliable systems. Observability lets you manage ongoing operations and critical events. Well-implemented observability helps you to build and maintain a reliable service for your users.


Consider the following recommendations:


Track infrastructure metrics for processors (CPUs, GPUs, and TPUs) and for other resources like memory usage, network latency, and disk usage. Perform load testing and performance monitoring. Use the test results and metrics from monitoring to manage scaling and capacity for your AI and ML systems.

Establish reliability goals and track application metrics. Measure metrics like throughput and latency for the AI applications that you build. Monitor the usage patterns of your applications and the exposed endpoints.

Establish model-specific metrics like accuracy or safety indicators in order to evaluate model reliability. Track these metrics over time to identify any drift or degradation. For efficient version control and automation, define the monitoring configurations as code.

Define and track business-level metrics to understand the impact of your models and reliability on business outcomes. To measure the reliability of your AI and ML services, consider adopting the SRE approach and define service level objectives (SLOs).

AI and ML perspective: Security :

This document in the Well-Architected Framework: AI and ML perspective provides an overview of principles and recommendations to ensure that your AI and ML deployments meet the security and compliance requirements of your organization. The recommendations in this document align with the security pillar of the Google Cloud Well-Architected Framework.

Consider the following recommendations:

Identify potential attack vectors and adopt a security and compliance perspective from the start. As you design and evolve your AI systems, keep track of the attack surface, potential risks, and obligations that you might face.

Align your AI and ML security efforts with your business goals and ensure that security is an integral part of your overall strategy. Understand the effects of your security choices on your main business goals.

Consider the following recommendations:

Don't collect, keep, or use data that's not strictly necessary for your business goals. If possible, use synthetic or fully anonymized data.

Monitor data collection, storage, and transformation. Maintain logs for all data access and manipulation activities. The logs help you to audit data access, detect unauthorized access attempts, and prevent unwanted access.

Implement different levels of access (for example, no-access, read-only, or write) based on user roles. Ensure that permissions are assigned based on the principle of least privilege. Users must have only the minimum permissions that are necessary to let them perform their role activities.

Implement measures like encryption, secure perimeters, and restrictions on data movement. These measures help you to prevent data exfiltration and data loss.

Guard against data poisoning for your ML training systems.


Keep AI pipelines secure and robust against tampering

Your AI and ML code and the code-defined pipelines are critical assets. Code that isn't secured can be tampered with, which can lead to data leaks, compliance failure, and disruption of critical business activities. Keeping your AI and ML code secure helps to ensure the integrity and value of your models and model outputs.


Consider the following recommendations:

Use secure coding practices, such as dependency management or input validation and sanitization, during model development to prevent vulnerabilities.

Protect your pipeline code and your model artifacts, like files, model weights, and deployment specifications, from unauthorized access. Implement different access levels for each artifact based on user roles and needs.

Enforce lineage and tracking of your assets and pipeline runs. This enforcement helps you to meet compliance requirements and to avoid compromising production systems.


Deploy on secure systems with secure tools and artifacts

Ensure that your code and models run in a secure environment that has a robust access control system with security assurances for the tools and artifacts that are deployed in the environment.


Consider the following recommendations:


Train and deploy your models in a secure environment that has appropriate access controls and protection against unauthorized use or manipulation.

Follow standard Supply-chain Levels for Software Artifacts (SLSA) guidelines for your AI-specific artifacts, like models and software packages.

Prefer using validated prebuilt container images that are specifically designed for AI workloads.


Protect and monitor inputs

AI systems need inputs to make predictions, generate content, or automate actions. Some inputs might pose risks or be used as attack vectors that must be detected and sanitized. Detecting potential malicious inputs early helps you to keep your AI systems secure and operating as intended.


Consider the following recommendations:

Implement secure practices to develop and manage prompts for generative AI systems, and ensure that the prompts are screened for harmful intent.

Monitor inputs to predictive or generative systems to prevent issues like overloaded endpoints or prompts that the systems aren't designed to handle.

Ensure that only the intended users of a deployed system can use it.



Monitor, evaluate, and prepare to respond to outputs

AI systems deliver value because they produce outputs that augment, optimize, or automate human decision-making. To maintain the integrity and trustworthiness of your AI systems and applications, you need to make sure that the outputs are secure and within expected parameters. You also need a plan to respond to incidents.


Consider the following recommendations:


Monitor the outputs of your AI and ML models in production, and identify any performance, security, and compliance issues.

Evaluate model performance by implementing robust metrics and security measures, like identifying out-of-scope generative responses or extreme outputs in predictive models. Collect user feedback on model performance.

Implement robust alerting and incident response procedures to address any potential issues.


Build a robust foundation for model development, Well Architected framework , AI Perspective : Part 2

Implement observability

The behavior of AI and ML systems can change over time due to changes in the data or environment and updates to the models. This dynamic nature makes observability crucial to detect performance issues, biases, or unexpected behavior. This is especially true for generative AI models because the outputs can be highly variable and subjective. Observability lets you proactively address unexpected behavior and ensure that your AI and ML systems remain reliable, accurate, and fair.


You can use Vertex AI Model Monitoring to proactively track model performance, identify training-serving skew and prediction drift, and receive alerts to trigger necessary model retraining or other interventions. To effectively monitor for training-serving skew, construct a golden dataset that represents the ideal data distribution, and use TFDV to analyze your training data and establish a baseline schema.


Configure Model Monitoring to compare the distribution of input data against the golden dataset for automatic skew detection. For traditional ML models, focus on metrics like accuracy, precision, recall, F1-score, AUC-ROC, and log loss. Define custom thresholds for alerts in Model Monitoring. 


You can also enable automatic evaluation metrics for response quality, safety, instruction adherence, grounding, writing style, and verbosity. To assess the generated outputs for quality, relevance, safety, and adherence to guidelines, you can incorporate human-in-the-loop evaluation.


Use Vertex AI rapid evaluation to let Google Cloud automatically run evaluations based on the dataset and prompts that you provide.



Use adversarial testing to identify vulnerabilities and potential failure modes. To identify and mitigate potential biases, use techniques like subgroup analysis and counterfactual generation. Use the insights gathered from the evaluations that were completed during the development phase to define your model monitoring strategy in production. Prepare your solution for continuous monitoring as described in the Monitor performance continuously section of this document


Monitor for availability

To gain visibility into the health and performance of your deployed endpoints and infrastructure, use Cloud Monitoring. For your Vertex AI endpoints, track key metrics like request rate, error rate, latency, and resource utilization, and set up alerts for anomalies. For more information, see Cloud Monitoring metrics for Vertex AI.


Monitor the health of the underlying infrastructure, which can include Compute Engine instances, Google Kubernetes Engine (GKE) clusters, and TPUs and GPUs. Get automated optimization recommendations from Active Assist. If you use autoscaling, monitor the scaling behavior to ensure that autoscaling responds appropriately to changes in traffic patterns.



For timely identification and rectification of anomalies and issues, set up custom alerting based on thresholds that are specific to your business objectives. Examples of Google Cloud products that you can use to implement a custom alerting system include the following:


Cloud Logging: Collect, store, and analyze logs from all components of your AI and ML system.

Cloud Monitoring: Create custom dashboards to visualize key metrics and trends, and define custom metrics based on your needs. Configure alerts to get notifications about critical issues, and integrate the alerts with your incident management tools like PagerDuty or Slack.

Error Reporting: Automatically capture and analyze errors and exceptions.

Cloud Trace: Analyze the performance of distributed systems and identify bottlenecks. Tracing is particularly useful for understanding latency between different components of your AI and ML pipeline.

Cloud Profiler: Continuously analyze the performance of your code in production and identify performance bottlenecks in CPU or memory usage.


Prepare for peak events

Ensure that your system can handle sudden spikes in traffic or workload during peak events. Document your peak event strategy and conduct regular drills to test your system's ability to handle increased load.


To aggressively scale up resources when the demand spikes, configure autoscaling policies in Compute Engine and GKE. For predictable peak patterns, consider using predictive autoscaling. To trigger autoscaling based on application-specific signals, use custom metrics in Cloud Monitoring.

To develop and deploy scalable, reliable AI systems that help you achieve your business goals, a robust model-development foundation is essential. Such a foundation enables consistent workflows, automates critical steps in order to reduce errors, and ensures that the models can scale with demand. A strong model-development foundation ensures that your ML systems can be updated, improved, and retrained seamlessly. The foundation also helps you to align your models' performance with business needs, deploy impactful AI solutions quickly, and adapt to changing requirements.

To build a robust foundation to develop your AI models, consider the following recommendations.

Define the problems and the required outcomes

Before you start any AI or ML project, you must have a clear understanding of the business problems to be solved and the required outcomes. Start with an outline of the business objectives and break the objectives down into measurable key performance indicators (KPIs).

To organize and document your problem definitions and hypotheses in a Jupyter notebook environment, use tools like Vertex AI Workbench. To implement versioning for code and documents and to document your projects, goals, and assumptions, use tools like Git. To develop and manage prompts for generative AI applications, you can use Vertex AI Studio.

Collect and preprocess the necessary data

To implement data preprocessing and transformation, you can use Dataflow (for Apache Beam), Dataproc (for Apache Spark), or BigQuery if an SQL-based process is appropriate. To validate schemas and detect anomalies, use TensorFlow Data Validation (TFDV) and take advantage of automated data quality scans in BigQuery where applicable

To create synthetic datasets based on existing patterns or to augment training data for better model performance, use BigQuery DataFrames and Gemini. Synthetic data is particularly valuable for generative AI because it can help improve prompt diversity and overall model robustness. When you build datasets for fine-tuning generative AI models, consider using the synthetic data generation capabilities in Vertex AI.

For generative AI tasks like fine-tuning or reinforcement learning from human feedback (RLHF), ensure that labels accurately reflect the quality, relevance, and safety of the generated outputs.

Select an appropriate ML approach

When you design your model and parameters, consider the model's complexity and computational needs. Depending on the task (such as classification, regression, or generation), consider using Vertex AI custom training for custom model building or AutoML for simpler ML tasks. For common applications, you can also access pretrained models through Vertex AI Model Garden. You can experiment with a variety of state-of-the-art foundation models for various use cases, such as generating text, images, and code.



You might want to fine-tune a pretrained foundation model to achieve optimal performance for your specific use case. For high-performance requirements in custom training, configure Cloud Tensor Processing Units (TPUs) or GPU resources to accelerate the training and inference of deep-learning models, like large language models (LLMs) and diffusion models.


Set up version control for code, models, and data

To manage and deploy code versions effectively, use tools like GitHub or GitLab. These tools provide robust collaboration features, branching strategies, and integration with CI/CD pipelines to ensure a streamlined development process.


Use appropriate solutions to manage each artifact of your ML system, like the following examples:


For code artifacts like container images and pipeline components, Artifact Registry provides a scalable storage solution that can help improve security. Artifact Registry also includes versioning and can integrate with Cloud Build and Cloud Deploy.


To manage data artifacts, like datasets used for training and evaluation, use solutions like BigQuery or Cloud Storage for storage and versioning.


To maintain the consistency and versioning of your feature data, use Vertex AI Feature Store. To track and manage model artifacts, including binaries and metadata, use Vertex AI Model Registry, which lets you store, organize, and deploy model versions seamlessly.


To ensure model reliability, implement Vertex AI Model Monitoring. Detect data drift, track performance, and identify anomalies in production. For generative AI systems, monitor shifts in output quality and safety compliance.

What is google cloud Run ?

What is Google Cloud Run?

Google Cloud Run is a fully managed serverless compute platform that allows you to deploy and run containerized applications that scale automatically. It brings the flexibility of containers with the simplicity and cost-effectiveness of serverless computing.

In essence, Cloud Run lets you:

Deploy containers: You package your application and its dependencies into a Docker or OCI-compatible container image. This means you can use any programming language, framework, or library you want.

Run serverless: You don't need to provision, configure, or manage any servers, clusters, or underlying infrastructure. Google Cloud handles all of that for you.

Scale to zero: When your application isn't receiving any requests, Cloud Run scales down to zero instances, meaning you pay nothing for idle time. When traffic increases, it automatically scales up rapidly to handle the load.

Pay-per-use: You only pay for the CPU, memory, and network resources consumed when your code is actively processing requests.

Handle HTTP requests or events: Cloud Run is ideal for stateless, request-driven services (like web APIs, microservices, websites) and also supports event-driven workloads (e.g., processing messages from Cloud Pub/Sub, Cloud Storage events). It also has "Jobs" for running short-lived, batch workloads to completion.

Key characteristics of Cloud Run:

Serverless: No server management.

Container-based: Portability and language agnosticism.

Fully managed: Google handles infrastructure, scaling, patching, etc.

Auto-scaling: Scales from zero to thousands of instances based on traffic.

Pay-per-use pricing: Cost-effective for variable workloads.

Fast deployments: Quick iteration and deployment cycles.

Integrated with GCP: Seamlessly connects with other Google Cloud services like Cloud SQL, Cloud Storage, Pub/Sub, and Vertex AI.

Common Use Cases:


RESTful APIs and microservices

Web applications and static websites (though often paired with Cloud Storage or Firebase Hosting for static assets)

Event-driven processing (e.g., image processing on upload, data transformation)

Chatbots and backend for mobile apps

Batch jobs and cron jobs (using Cloud Run Jobs)

Machine learning model serving (APIs)

Difference Between Google Cloud Run and GKE (Google Kubernetes Engine)

Both Google Cloud Run and Google Kubernetes Engine (GKE) are powerful platforms for deploying and managing containerized applications on Google Cloud. However, they cater to different needs and offer different levels of control and abstraction.



When to Choose Which:

Choose Cloud Run if:


You want to get a containerized application running quickly with minimal operational overhead.

Your application is stateless or can externalize its state to managed databases/storage.

You have highly variable or infrequent traffic, and you want to optimize costs by scaling to zero.

Your team prefers a serverless development model and doesn't want to manage Kubernetes.

You need to deploy APIs, web services, or event-driven functions.

Choose GKE if:


You need fine-grained control over your container orchestration environment.

Your application is stateful and requires persistent storage directly managed by the orchestration platform.

You have complex microservice architectures with intricate networking, service mesh, or specialized hardware requirements.

Your team has Kubernetes expertise or is willing to invest in learning it.

You have very predictable, constant workloads where fixed resource costs might be more economical than pay-per-use (though this depends on the scale).

You need advanced features like custom schedulers, node pools with specific machine types (e.g., GPUs for ML training), or deep integration with underlying infrastructure.

Can you use both? Absolutely! Many organizations adopt a hybrid approach. For example, they might use Cloud Run for simple, stateless microservices or event-driven functions, and GKE for more complex, stateful, or highly customized core applications. This allows them to leverage the best of both worlds – simplicity and cost-efficiency where possible, and control where necessary.

What's Imagen in Google AI ?

Imagen is Google's powerful text-to-image diffusion model, designed to generate high-quality, realistic images from natural language descriptions. While Gemini models (like Gemini 1.5 Pro) also have strong image generation capabilities as part of their multimodal nature, Imagen is a specialized model specifically engineered for superior text-to-image synthesis and fine-grained control over the generated visuals.

You mentioned "Imagen (via Vertex AI or specific Gemini features)." Let's break down how it's used and its advantages:

How Imagen Can Be Used

Imagen is primarily accessed and utilized through Google Cloud's Vertex AI, specifically within its Generative AI capabilities. There are multiple ways to interact with Imagen:


Vertex AI Studio (Console UI):


This provides a user-friendly graphical interface in the Google Cloud console. Teachers (or developers creating the Sahayak app) can go to the Vertex AI > Media Studio page, select Imagen, and then type in their text prompts.


It offers options to configure settings like aspect ratio, number of results (typically 1-4 images per prompt), and advanced safety settings.

It supports text-to-image generation (creating an image from scratch based on a description).

It also supports image editing, including:

Mask-based editing (Inpainting/Outpainting): You can upload an image, define a mask (an area to edit), and then use a text prompt to insert new content into the masked area (inpainting insert), remove content (inpainting removal), or extend the image beyond its original boundaries (outpainting). You can even automatically generate masks for foreground/background or semantic objects.



Mask-free editing: Modify the entire image based on a new text prompt.

Product image editing: Automatically detect objects to maintain them while modifying the background.

Image Upscaling: Improve the resolution of existing or generated images.

Image customization by reference images: Provide reference images to guide the generation style or subject.

Gemini API (specific image generation modes):


While Gemini models have their own image generation, the Gemini API can also integrate with Imagen models (like Imagen 3, Imagen 4) for specialized tasks where image quality is critical.

Developers can prompt Gemini with text, images, or a combination. When requesting image outputs explicitly, the API can leverage Imagen's specialized capabilities.


This means that for your "Sahayak" app, a teacher interacting with Gemini could implicitly trigger Imagen in the background if the request is best served by Imagen's strengths (e.g., "Generate a highly realistic diagram of the water cycle").

Client Libraries and APIs (for developers):


Developers can integrate Imagen capabilities into their applications using Python, Java, Go, or REST APIs. This is how the "Sahayak" app would programmatically make requests to Imagen based on the teacher's input.

This allows for programmatic control over prompt parameters, image settings, and processing.

Benefits of Using Imagen

Imagen offers several significant advantages, especially for use cases demanding high fidelity, control, and specific artistic styles:


 High-Quality, Photorealistic Image Generation: Imagen is renowned for its ability to produce photorealistic images with impressive detail, richer lighting, and fewer artifacts. This is achieved through its unique architecture, which combines large transformer language models (like T5) for deep text understanding with cascaded diffusion models for high-fidelity image generation and super-resolution.



Strong Text-to-Image Alignment: Imagen excels at understanding complex and nuanced text prompts, generating images that accurately reflect the textual description. This means teachers can provide detailed requests for visual aids, and Imagen will strive to render them precisely.



Versatile Styling and Control:


It supports various artistic styles (e.g., cinematic, 35mm film, illustration, surreal, watercolor, line drawing), allowing teachers to specify the desired aesthetic for their visual aids.

It offers control over aspect ratios (e.g., 1:1, 16:9, 4:3), useful for different teaching aid formats.

 Advanced Image Editing Capabilities: Beyond generating images from scratch, Imagen's robust editing features (mask-based editing, mask-free editing, product image editing) are incredibly beneficial for modifying existing images or iterating on generated ones. For "Sahayak", this means a teacher could refine a generated diagram or adapt a photo for a specific teaching purpose.


Seamless Integration within Google Cloud Ecosystem:


As part of Vertex AI, Imagen benefits from Google Cloud's scalable infrastructure, MLOps tooling, and responsible AI practices (e.g., safety filters, digital watermarking with SynthID to identify AI-generated content).

Its accessibility via the Gemini API provides flexibility for developers building multimodal applications.

 Rapid Prototyping and Iteration: For artists, designers, and educators, Imagen allows for immediate, tangible feedback from text descriptions, significantly accelerating the ideation and content creation process. Teachers can quickly generate multiple visual aids and iterate on them until they get the perfect one.


Text Rendering in Images (Improved): Newer versions of Imagen (like Imagen 4) have significantly improved capabilities for rendering coherent and accurate text within generated images, which is crucial for creating worksheets or diagrams with labels.


In the context of the "Sahayak" AI companion for under-resourced schools, Imagen's ability to create high-quality, relevant, and customizable visual aids from simple text descriptions would be a game-changer, empowering teachers to produce engaging and effective learning materials even with limited traditional resources.


What is Gemini Vison and also give major advantages using GEmini vision compared to other models?

"Gemini Vision" isn't a separate, standalone product like Google Cloud Vision API. Instead, it refers to the multimodal capabilities of Google's Gemini family of AI models, specifically their ability to understand and process visual inputs (images and videos) alongside text, code, and audio.


When you interact with a Gemini model (like Gemini Pro or Gemini 1.5 Pro) and provide it with an image or video, you are using its "vision" capabilities. The model is "multimodal from the ground up," meaning it was trained to natively understand and reason across these different modalities simultaneously, rather than having separate components for each.



Major Advantages of Using Gemini Vision Compared to Other Models

The key advantages of using Gemini's vision capabilities stem from its native multimodality and its integrated reasoning across modalities:


True Multimodality from the Ground Up:


Seamless Integration: Unlike many older systems that might use separate encoders for text and images and then fuse their outputs at a later stage, Gemini was designed from the beginning to process various data types using shared network layers. This allows for a deeper, more inherent understanding of how visual and textual information relate to each other.

Unified Reasoning: It can reason about an image, its embedded text, and a natural language question about it all within a single model, leading to more nuanced and context-aware responses. This is a significant improvement over models that merely concatenate features from different modalities.


Sophisticated Reasoning and Contextual Understanding:


Complex Visual Question Answering (VQA): Gemini can answer complex questions about images that require not just object recognition but also an understanding of relationships, actions, and implicit context. For example, "Explain the scientific process shown in this diagram" or "What is the person in this image likely feeling?"

Digital Content Understanding: It excels at extracting information from various visual documents like infographics, charts, tables, web pages, and even screenshots. It can understand layouts and logical structures within images.


Cross-Modal Connections: Its training on aligned multimodal data at an unprecedented scale creates rich conceptual connections between what things look like, how they're described, and how they behave (in videos).

Flexibility in Input and Output:


Interleaved Inputs: You can provide a prompt that mixes text and multiple images (and even video/audio in newer versions like Gemini 1.5 Pro), allowing for highly contextual and dynamic interactions. For example, "Here's a photo of my garden. What are these plants, and how should I care for them? [Image 1] [Image 2]"

Structured Output Generation: Gemini Vision can generate responses in structured formats like JSON or HTML based on multimodal inputs, which is incredibly useful for integrating AI output into downstream applications and databases.

Long Context Window (especially Gemini 1.5 Pro/Flash):


While not exclusively a "vision" advantage, the large context window of Gemini 1.5 Pro (up to 1 million tokens or more) means you can feed it extremely long documents that include images and receive a coherent response. This is a massive leap for processing large visual documents or video transcripts.

Integration with the Google Ecosystem:


Vertex AI: Gemini models are accessible through Vertex AI, Google Cloud's MLOps platform, which provides tools for managing, deploying, and monitoring AI models at scale. This includes features like safety filters, prompt management, and integration with other GCP services.

Google's Research and Infrastructure: Benefits from Google's extensive research in AI and its robust, scalable infrastructure (like TPUs), which powers its training and inference.

Potential for "Agentic" Behavior:


Gemini's design is geared towards developing AI agents that can understand their environment, predict actions, and take action on behalf of users, potentially leveraging vision to perceive and interact with digital or real-world interfaces.

Compared to other models (e.g., GPT-4V, LLaVA, Claude 3):

While other multimodal models like OpenAI's GPT-4V, LLaVA, and Anthropic's Claude 3 family also offer impressive vision capabilities, Gemini's competitive edge often lies in:


Native Design: Its ground-up multimodal architecture is often highlighted as a differentiator, leading to potentially more cohesive cross-modal reasoning.

Scale and Context: Gemini 1.5 Pro's massive context window (1 million tokens) surpasses many competitors for processing very long multimodal inputs.

Integration: For developers already invested in the Google Cloud ecosystem, Gemini offers very tight integration and familiar tooling.

Performance vs. Cost Tiers: The availability of different Gemini models (Ultra, Pro, Flash, Nano) allows developers to choose a model optimized for specific needs (e.g., Gemini Flash for speed and cost-efficiency in high-volume, latency-sensitive visual tasks).

In essence, Gemini Vision isn't a separate tool but a fundamental aspect of the Gemini family of models that allows them to "see," "understand," and "reason" about the visual world in a deeply integrated way, significantly expanding the range and sophistication of AI applications

What Android XR

XR stands for extended reality. It’s an umbrella term that encompasses all technologies that blend the real and virtual worlds including virtual reality, augmented reality, and mixed reality. Android XR is an operating system for extended reality devices that use these technologies, like headsets and glasses. It provides the user interface, the ability to access popular apps, and AI assistance from Gemini to these devices.


Android XR is an operating system for headsets and glasses. The first devices will be available in 2025.


The first devices with Android XR will be available in 2025.


Android XR compatible mobile app

An Android XR compatible mobile app represents an existing mobile app that has not been modified to adapt to a large screen or any other form factor. This type of app is automatically compatible with Android XR as long as it doesn't require any features that are unsupported, such as telephony. Users can complete critical task flows but with a less optimal user experience than an Android XR differentiated app.


This type of app runs full screen on a panel in the user's environment, but its layout might not be ideal at larger sizes. Apps that specify compact sizes in the manifest show up accordingly. The app doesn't run in compatibility mode and is therefore not letterboxed. The app has a functional experience of the core input modalities provided by Android XR (eye tracking + gesture or raycast hands) and basic support for external input devices, including keyboard, mouse, trackpad, and game controllers. It may or may not be capable of resizing.


Android XR compatible mobile apps are automatically opted in and available on the Google Play Store. An app that is not compatible because of unsupported feature requirements is not installable through the Play Store.


Android XR differentiated app

An Android XR differentiated app has a user experience explicitly designed for XR and it implements features that are only offered on XR. You can take full advantage of Android XR capabilities and differentiate your app's experiences by adding XR features (e.g. spatial panels), adding XR content (e.g. 3D video) to your applications by developing with Android Jetpack XR SDK, Unity, or OpenXR.


You can use the Jetpack XR SDK to provide XR-specific capabilities including spatial panels, environments, 3D models, spatial audio, 3D / spatial video / photos, anchors, and other spatial UI such as orbiters.
