I noticed that when I use the concurrent model feature, the context from one session, pollutes the context of the other sessions. I'm not sure if this is a UI thing or something in ollama.
Installation Method
I used git clone, and I do the same with ollama.
I run both open-webui and ollama as systemd services.
Environment
Open WebUI Version: 0.5.2 (Is this exposed in the UI somewhere?)
Ollama (if applicable): 0.4.5
Operating System: Kubuntu 24.10
Browser (if applicable): Chrome 132 on Windows 10.
Confirmation:
I have read and followed all the instructions provided in the README.md.
I am on 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 provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.
Expected Behavior:
I expected that the session context for each model would remain independent.
Actual Behavior:
I observed that all three model sessions repeated the same unique word.
Description
I asked all three models to produce a random word.
I asked all three models to repeat their random word.
All three models repeated the random word chosen by the third model.
Bug Summary:
Reproduction Details
Steps to Reproduce:
Enable three models to concurrently respond to prompts.
Prompt the models to generate a random word.
Prompt the models to repeat their random word.
Note that the models all repeat the same word.

Intended behaviour here, you choose the response from the model and that's what gets fed into as an answer in the next turn!

I misunderstood the feature. Although the way I thought it worked still sounds interesting.
Thank you.
