因为dify没有适配 /responses 接口,所以gpt-5.1-codex全系列添加模型都报错,一时半会用不了,慢慢等适配吧

Hi, @Caixiaopig. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You requested support for the new gpt-5.1-codex-max model in Dify's Azure OpenAI plugins, emphasizing its advanced reasoning capabilities and the need to set reasoning_effort to xhigh.
  • You noted that reasoning_effort none is unsupported and provided a Microsoft documentation link for reference.
  • The maintainer explained that Dify currently does not support the /responses endpoint required by this model, which leads to errors.
  • No code contributions have been offered yet, and the issue remains unresolved pending proper integration.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here to keep the discussion open.
  • If I do not hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!
