Generate comprehensive API references, endpoint descriptions, and usage examples. Large context windows help understand your entire API structure while large output capacity generates detailed docs in one go.
Create project READMEs with installation instructions, feature highlights, and examples. AI can analyze your codebase and write clear, well-structured documentation that developers actually want to read.
Build and maintain internal knowledge bases, FAQ sections, and runbooks. Streaming capabilities let you preview documentation as it's generated, while JSON mode ensures structured, parseable outputs.
Write tutorials, architecture guides, and best practices documentation. Reasoning capabilities help generate technically accurate guides that explain the "why" behind recommendations, not just the "how."
