Bug Report

Text Generation Hangs

Bug Summary:
Using Open WebUI, when prompting a model (e.g. Llama 70B), text generation stops after a while and the stop button is also unresponsive. Context length both tested default and 8K. Reloading the page allows to chat again, but the unfinished answer isn't saved. Using ollama directly doesn't have this issue (screenshots provided for comparison).

Steps to Reproduce:
Prompt the model for longer answers.

Expected Behavior:
The LLM is supposed to complete the answer and/or the stop button should allow for ending the text generation.

Environment

  • Open WebUI Version:0.2.5
  • Ollama (if applicable):1.4.1
  • Operating System: Linux / Docker Installation

Logs and Screenshots
