Introduction¶
Artificial Intelligence is not just about creating intelligent agents but also about ensuring that these agents operate at peak performance. With Amazon Bedrock AgentCore Evaluations now available, developers have a powerful tool for monitoring agent quality through continuous evaluation of production traffic. In this guide, you’ll learn everything from foundational concepts to advanced setup, ensuring you’re well-equipped to implement these evaluations in your workflows.
Understanding Amazon Bedrock AgentCore Evaluations¶
What is AgentCore?¶
Amazon Bedrock AgentCore is a foundational framework designed to support the deployment, monitoring, and evaluation of AI agents. With growing complexity in AI interactions, ensuring quality and reliability becomes paramount. AgentCore Evaluations helps teams address these challenges by providing systematic approaches for quality measurement and performance tuning.
Benefits of AgentCore Evaluations¶
- Automated Quality Assessment: Continuous evaluation means that agents can be monitored in production without manual intervention.
- Performance Monitoring: By evaluating live production traffic, organizations can quickly identify performance bottlenecks or areas for improvement.
- Simplified Testing Workflows: On-demand evaluations support agile development processes, allowing for immediate feedback.
- Customizability: Teams can create custom evaluators tailored to their specific tasks or industry needs.
How AgentCore Evaluations Work¶
Online Evaluations¶
Online evaluations continuously monitor the performance of a deployed agent by sampling and scoring live traces. This means that as users interact with the AI agent, its responses are evaluated in real-time against predefined metrics.
- Response Quality
- Safety of Responses
- Task Completion Rate
- Tool Usage Effectiveness
On-Demand Evaluations¶
With on-demand evaluations, teams can conduct assessments programmatically. This capability is particularly useful for:
- Regression Testing: Ensure that new updates don’t negatively impact existing functionalities.
- Continuous Integration/Continuous Deployment (CI/CD): Integrate evaluations into CI/CD pipelines for seamless development.
- Interactive Workflows: Test agents during development and fine-tune them based on immediate feedback.
Setting Up Amazon Bedrock AgentCore Evaluations¶
Pre-requisites¶
Before you can start using AgentCore Evaluations, ensure you have the following:
- An active AWS account
- Familiarity with Amazon Bedrock services
- Basic knowledge of evaluation metrics and requirements for your specific use case
Getting Started with AgentCore Evaluations¶
- Access the AWS Management Console: Log in to your AWS account, and navigate to the Amazon Bedrock service.
- Create an Agent: Define the AI agent you wish to evaluate. Make sure it meets the necessary configurations and performance benchmarks.
- Configure Evaluations: Choose between online and on-demand evaluations based on your product lifecycle needs.
Example on Amazon Bedrock:¶
Here’s a quick step-up guide to implement evaluations:
- Open Amazon Bedrock:
Navigate to the dashboard and select the ‘Agents’ tab.
Select Your Agent:
Click on the agent you want to evaluate and select the tab for evaluations.
Choose Evaluation Type:
Select either online or on-demand as per your requirement.
Define Metrics:
Choose the built-in evaluators or create custom metrics that align with your objectives.
Run Evaluations:
- Start the evaluation, and the system will compile reports based on the performance against selected benchmarks.
Evaluating AI Agents: A Deep Dive¶
Built-in Evaluators¶
AgentCore Evaluations come with 13 built-in evaluators that assess several aspects of agent performance:
- Response Quality: Validates the accuracy and coherence of responses.
- Safety: Checks for harmful or inappropriate content.
- Task Completion: Measures how effectively the agent completes assigned tasks.
- Tool Utilization: Evaluates how well agents use available tools to enhance responses.
These evaluators provide immediate insights, enabling swift action on any highlighted issues.
Custom Evaluators¶
For organizations with unique requirements, custom evaluators can be created. Here’s how:
- Use Ground Truth: Validate your agent’s responses against a set of reference answers.
- Behavioral Assertions: Define expected actions for session-level goals.
- Execution Sequences: Anticipate the order of tool usage during interactions.
Custom evaluators can utilize prompts for LLM-based evaluations or implement logic through AWS Lambda using Python or JavaScript.
Integration with AgentCore Observability¶
AgentCore Evaluations integrates seamlessly with AgentCore Observability—AWS’s unified monitoring system. Real-time alerts and analytics provide insights into:
- Agent performance trends
- Bottlenecks in service delivery
- User interaction patterns
By utilizing observability, organizations can maintain control over agent health and proactively address issues.
Real-world Applications of AgentCore Evaluations¶
- Customer Support: Elevate the quality of customer interactions through better agent evaluations, leading to enhanced user satisfaction.
- E-commerce: Assess chatbot performance efficiently to ensure a smooth shopping experience.
- Healthcare: Monitor AI-driven medical advisors to adhere to clinical guidelines and patient safety protocols.
Best Practices for Effective Evaluations¶
- Define Clear Objectives: Know what success looks like for your AI agent. Clear objectives will guide your evaluation process.
- Utilize Multiple Evaluators: Combine built-in and custom evaluators for a comprehensive understanding of agent performance.
- Regularly Update Evaluation Metrics: As the AI landscape evolves, so should your evaluation metrics.
- Iterate and Test Frequently: Take advantage of on-demand evaluations to continuously refine and improve agent performance.
