The honest brief

Inspect AI

Built by the UK AI Security Institute and adopted by Anthropic, DeepMind, METR, and Apollo as a shared eval framework; MIT.

  • Adopted across major safety labs
  • Composable datasets/solvers/scorers
  • 200+ prebuilt evals (inspect_evals)
  • Sandboxed tool + multi-turn agent runs
  • MIT-licensed, provider-agnostic
  • Python/code framework, not a UI product
  • Steeper than no-code eval tools
  • You wire up your own model keys

Ragas

Popularized reference-free RAG metrics — faithfulness, context precision — scored by an LLM judge, so you evaluate without gold answers.

  • Faithfulness & relevancy metrics
  • Knowledge-graph synthetic test sets
  • LLM-as-judge scoring
  • Integrates LangChain, LlamaIndex, CI
  • LLM-judge scores add cost/variance
  • Python library, no hosted UI
  • Focused on RAG, narrower scope
