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.
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).
