Evals
Automated tests that grade LLM outputs against expected behavior.
/ quick answer
Evals are the unit tests of AI systems. Each eval is an input, an expected property (exact match, LLM-judge score, latency budget), and a pass/fail. Ship without evals and you fly blind. Automated tests that grade LLM outputs against expected behavior.
What is Evals?
Evals are the unit tests of AI systems. Each eval is an input, an expected property (exact match, LLM-judge score, latency budget), and a pass/fail. Ship without evals and you fly blind.
What is an example of Evals?
An eval suite runs 200 real support questions nightly; a regression alerts if grounded-answer accuracy drops below 92%.
