OpenAI staff shared a new "Model guidance" docs page collecting the company's official prompting and model-guidance best practices. It indexes the full API documentation surface: Responses API, Agents SDK, reasoning models, fine-tuning (SFT, DPO, RFT), evals and graders, prompt optimization, image/video generation, and realtime voice. Pages are available in Markdown by appending .md to the URL, with an llms.txt index for AI tooling.
