Operating System

Browser (if applicable)

Confirmation
I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have listed steps to reproduce the bug in detail.
Expected Behavior
User can only generate one chat at a time
Actual Behavior
User can go through the chat list and click regenerate on every chat.
User can leave the chat while regenerating, go into another chat, regenerate that one and continue onto other chats.
This can in effect create a denial of service for the LLM backend. For local models, this could quickly prevent other people from using your service. For remote models, if your API key can only generate so many concurrent chats at once, this will overwhelm it.
Steps to Reproduce
described above
Logs & Screenshots
