Support for new Open AI Responses API #4221
Description
Expected Behavior
OpenAI has introduced the new Responses API, and developers are encouraged to migrate from the legacy Completions API to this updated interface. Spring AI should support this new API so applications can leverage its enhanced functionality and stay aligned with OpenAI’s roadmap.
Current Behavior
Spring AI currently only supports the older ChatCompletion API, with no built-in support for the newer Responses API.
Context
The AI ecosystem evolves rapidly, and without support for the Responses API, Spring AI lags behind OpenAI’s recommended approach. Adding support would ensure developers can take advantage of the latest features, improvements, and future-proof their integrations.
