Check Existing Issues

I have searched for all existing open AND closed issues and discussions for similar requests. I have found none that is comparable to my request.

Verify Feature Scope

I have read through and understood the scope definition for feature requests in the Issues section. I believe my feature request meets the definition and belongs in the Issues section instead of the Discussions.

Problem Description

Currently, Open WebUI triggers the image generation (ComfyUI/Automatic1111) immediately when the user sends a message. This makes it impossible for the LLM to act as a "Prompt Architect." If a user provides a simple or non-English request, the Image Engine receives a poor prompt, leading to suboptimal results. There is no "Chain of Thought" where the LLM can plan or refine the prompt before the GPU starts rendering.

Desired Solution you'd like

Implement a "Delayed Trigger" system:

LLM Refinement: The LLM first processes the user input, translates it into a detailed English prompt, and potentially selects a specific model/checkpoint.

Post-Response Trigger: Open WebUI should wait for the LLM to finish its response. Only then should it extract the final prompt (e.g., from brackets [...]) and send it to the Image Engine.

Dynamic Parameters: Allow the LLM to specify parameters like --model, --neg, or --cfg within its text output to dynamically control the image generation process.

You can already have the ai write the prompt and then press the little image button underneath the message which does exactly what you described.
