Migrate to the Responses API

For the complete documentation index, see llms.txt. Markdown versions of documentation pages are available by appending .md to the page URL.

The Responses API is our new API primitive, an evolution of Chat Completions which brings added simplicity and powerful agentic primitives to your integrations.

While Chat Completions remains supported, Responses is recommended for all new projects.
