SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a structured approach to rigorously evaluate AI model performance, ensuring reliability and tracking regressions through defined tests and metrics.

Core Features & Use Cases

  • Eval-Driven Development (EDD): Treat AI evaluations as unit tests for AI development.
  • Capability & Regression Evals: Define and run tests for new functionalities and to prevent existing ones from breaking.
  • Grading Mechanisms: Supports code-based, model-based, and human-in-the-loop grading.
  • Metrics: Tracks pass@k and pass^k for reliability measurement.
  • Use Case: A team developing a new AI coding assistant can use this Skill to define expected code generation quality, run these evaluations against new model versions, and ensure that bug fixes don't introduce new problems.

Quick Start

FAQPage Schema
What is eval-driven development for AI models?

Eval-driven development treats AI evaluations as unit tests for AI development, providing a structured approach to rigorously evaluate model performance, ensure reliability, and track regressions through defined tests and metrics.

How do I run regression evaluations to prevent AI model capabilities from breaking?

You can run regression evaluations by defining and executing tests against new AI model versions using this formal evaluation framework, ensuring that bug fixes and updates do not introduce new problems or break existing functionalities.

Can I use model-based and human-in-the-loop grading for AI capability evaluations?

Yes, the evaluation framework supports code-based, model-based, and human-in-the-loop grading mechanisms to assess AI capability evaluations, allowing you to flexibly verify model performance based on your specific testing requirements.

What metrics are used to measure AI reliability during model testing?

The framework tracks pass@k and pass^k metrics to measure AI reliability. These metrics provide quantitative tracking of model performance and pass rates across repeated evaluation sessions.

Does the AI evaluation framework require external dependencies to run capability tests?

No external dependencies are required to run the formal AI evaluation framework. It independently supports capability and regression evaluations, allowing you to define expected AI generation quality without prerequisite library installations.

What is the best way to define a new capability evaluation for an AI coding assistant?

The best way is to use the formal evaluation framework to define expected code generation quality, run these evaluations against new model versions, and verify that new functionalities meet the defined standards without causing regressions.
