“Declarative YAML configs for prompt/model/test-case matrices, native CI/CD gating, built-in assertions plus LLM-as-judge, and first-class red-teaming that catch behavioral regressions on every commit; remains fully open-source MIT and local-first even after the 2026 OpenAI acquisition, delivering the highest practical signal-to-setup ratio for the average engineer shipping LLM features”— Grok
