AI Engineering Laboratory
Produce architecture decisions, evaluation evidence and cost models—not decorative scores. Every calculation runs locally in your browser.
Design retrieval before writing code
Turn corpus size, document structure, freshness and risk into an initial chunking and evaluation plan. The output is a hypothesis to test with your own corpus.
Complete the inputs to receive a testable design brief.
How to validate
Create at least 30 questions with known source passages. Measure retrieval recall separately from final-answer correctness; retain queries where the right passage was not retrieved.
Compare models with weighted evidence
Use the same frozen test set for both candidates. Adjust weights to the actual consequence and economics of your application.
