Real-time LLM evaluation with sub-200ms guardrail models versus Prompt management, A/B testing, and evals for production LLM apps

Compare interactively in Explore →

Choose Galileo when…

  • You need real-time LLM guardrails in your production pipeline
  • You want eval models fast enough (<200ms) to run inline with inference
  • You need hallucination and RAG quality scoring at production latency

Choose Humanloop when…

  • managing prompts as production artifacts with version control
  • running A/B tests across different models and prompt variants
  • need human labeling and automated evals in one platform

Galileo

LLM evaluation platform with evaluation models that run in under 200ms — fast enough to use as production guardrails, not just offline eval. Covers hallucination detection, RAG quality, and safety scoring. Distinct from Galileo AI (the UI design tool).

Humanloop

Humanloop is a platform for managing prompts, running experiments, and evaluating LLM outputs in production. It provides a prompt editor, version history, A/B testing across models, and human plus automated eval workflows — keeping your prompts in sync with your code.
