1. Is this request related to a challenge you're experiencing? Tell me about your story.

I’m integrating GPT-5 Pro, which requires the OpenAI Responses API at the endpoint v1/responses. In Dify, both the OpenAI-API-compatible provider and the OpenAI official plugin currently target v1/chat/completions, which is incompatible with GPT-5 Pro. As a result, calls fail because the path is incorrect for models that only support the Responses API.

This blocks usage of GPT-5 Pro via Dify unless I bypass the built-in OpenAI-compatible integration. I’d like Dify to add first-class support for the Responses API so newer OpenAI models (like GPT-5 Pro) can be used without workarounds.

2. Additional context or comments

3. Can you help us with this feature?

Issue Summary:

  • You requested support for the OpenAI v1/responses API endpoint to enable compatibility with GPT-5 Pro.
  • Current support is limited to v1/chat/completions, causing integration challenges.
  • This enhancement would allow seamless use of GPT-5 Pro without workarounds.
  • There has been no activity or comments on this issue since it was opened.

Next Steps:

I really need this support too. Right now, I can only use gpt-5-chat on Dify, while all the other gpt-5 models require the Responses API.
