  • I am using the latest version of Open WebUI.

Installation Method

Other

Open WebUI Version

v0.6.10

Ollama Version (if applicable)

No response

Operating System

Windows 11

Browser (if applicable)

No response

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

The chat should generate a meaningful title using the LLM model associated with the initial message, based on the content and role. For example, instead of showing "New Chat", it should display something contextually relevant like "Help with API Integration".

Actual Behavior

Chat title generation fails consistently. All chats are labeled "New Chat", regardless of their content. Console and backend logs show a KeyError: 'model', indicating that the model information is not found at runtime.

Steps to Reproduce

  1. Start a new chat with any message.
  2. Let the assistant respond.
  3. Open the browser console or backend logs.
  4. Observe that no title is generated.
  5. Check logs and see: KeyError: 'model'.

Logs & Screenshots

File "/app/backend/open_webui/utils/middleware.py", line 1005, in background_tasks_handler
"model": message["model"],
└ {'role': 'assistant', 'content': 'Olá! Como posso ajudar?'}
KeyError: 'model'
