Bug Report

Installation Method

Docker Compose

Environment

  • Open WebUI Version: v0.3.35
  • Operating System: Sonoma 14.2
  • Browser (if applicable): 130.0.6723.117

Confirmation:

  • [x ] I have read and followed all the instructions provided in the README.md.
  • [x ] 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.
  • [ x] I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

Arena model should reveal the underlying model when rated on the chat screen and should appear on the evaluations page as the underlying model and be recorded in the leaderboard.

Actual Behavior:

Arena model does not reveal the underlying model when rated and does not appear on the evaluation page as the underlying unmasked model and is not recorded in the leaderboard rankings.

Description

Bug Summary:
When the arena model is not unmasked nor contributes to the leaderboard, it removes the utility of the feature.

Reproduction Details

Steps to Reproduce:
Enable 'Fluidly stream large external response chunks' under settings > interface
In a new chat, select two arena models to generate a sibling response.
Submit the prompt.
Give a thumbs up/down to one of the responses.
Note there the masked model is not revealed.
Go to the evaluation page and note the feedback lists the arena model name, not the unmasked model name.
Also on the evaluation page, note that the feedback is not reflected on the leaderboard.

Additional Information

It appears that 'Fluidly stream large external response chunks' under settings > interface being enabled is the root cause of this behavior. Returning this setting to its default setting of disabled resolves the issue.
