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

It would be great to get the option to have option for response mode "blocking" for chat agents. Right now only streaming is supported. For blocking, just the last reply of the LLM could be provided.

2. Additional context or comments

No response

3. Can you help us with this feature?

• I am interested in contributing to this feature.

Hi, @nl97. I'm helping the Dify team manage their backlog and am marking this issue as stale.

You opened this issue requesting the addition of a "blocking" response mode option for chat agents in the API, as the current implementation only supports streaming responses. This feature would allow users to receive a single, complete reply from the language model, which could enhance usability. However, there have been no further comments or developments on this issue yet.

Could you please let us know if this issue is still relevant to the latest version of the Dify repository? If it is, feel free to comment here to keep the discussion going. Otherwise, you can close the issue yourself, or it will be automatically closed in 7 days. Thank you!
