A model guide for the GPT-6 family

OpenAI has published a guide for using its GPT-6 family of models, which includes multiple versions designed for different types of work. The guide provides practical advice on preparing workflows for production, matching specific models to particular tasks, writing effective prompts, and managing long-running work that spans hours or days. The guidance covers techniques like prompt caching to reduce costs, adjusting reasoning effort levels based on task complexity, and using features like steering and asynchronous tools to keep complex tasks on track.
