FAQPage Schema
What is eval-driven development for AI-assisted coding?

It uses structured evaluation templates for capability and regression tests, supporting multi-grader setups including Code-Based, Model-Based, and Human Graders to measure pass@k metrics.

How do I set up an evaluation framework for AI coding sessions?

The framework supports capability and regression evals with measurable pass@k and pass^k metrics across code changes and prompts, integrating with CI-like workflows and project audits.

Can I use model-based and human graders together for code generation benchmarks?

This multi-grader approach allows you to combine deterministic grading with model rubrics and human evaluation to track run history and release-ready evaluations.

Does this evaluation framework support CI-like workflows and baseline management?

It implements storage patterns to track baselines, run history, and release-ready evaluations, enabling repeatable and objective assessment of AI coding capabilities.

What are the limitations of using a formal eval framework for AI coding?

Without proper baseline management and eval storage patterns, the framework cannot effectively track run history or determine release-ready evaluations across model changes.
