“Best docs” is subjective, but if I had to pick the most consistently developer-friendly LLM API docs, I’d say:
Top picks
1. OpenAI
- Very clear onboarding and examples
- Good API reference structure
- Strong code samples and guides
- Easy to find common tasks: chat, tools/function calling, structured outputs, streaming
Best for: developers who want the fastest path from zero to working code.
2. Anthropic
- Excellent conceptual explanations
- Strong focus on prompt design and tool use
- Good examples, especially for Claude-specific workflows
- Docs are generally polished and readable
Best for: developers who care about understanding behavior and building reliable integrations.
3. Google Gemini
- Solid docs, especially if you’re already in Google Cloud
- Good coverage of multimodal and platform integration
- Can feel more scattered due to ecosystem breadth
Best for: teams already invested in Google Cloud / Vertex AI.
Honorable mention: Cohere
- Quite developer-oriented
- Good docs for enterprise/search/embedding use cases
- Less mainstream than the above, so fewer community examples
My practical ranking for docs quality
- OpenAI
- Anthropic
- Google Gemini / Vertex AI
- Cohere
If you want, I can also rank them by:
- best API docs for beginners
- best docs for function calling / tools
- best docs for enterprise teams
- best docs for RAG / embeddings
