Snapshot testing for AI behavior — catch regressions offline in CI
A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.
Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.
Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.
Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.
