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).

OpenAI API

API access to GPT-4o, o1, and other OpenAI models including embeddings and image generation. The most widely used LLM API in production.
