About
Inspect AI is the evaluation framework from the UK AI Safety Institute, and it is MIT licensed with no signup. It ships with more than 200 pre-built evals covering agent tool use and reasoning, so you can benchmark your agent against standard tests instead of inventing your own. Install with pip and run evals from the command line.
