Chatting with the models is working great, the problem is displaying multiple models side-by-side.

My screen is wide enough for 3 columns, but the output is squished into about 50% of the screen.

I didn't see anyone report a "width" or "multiple" bug.

Installation Method

$ uv tool install open-webui
$ uv tool run open-webui serve

Environment

Open WebUI Version: v0.5.2
Ollama (if applicable): 0.5.4
Operating System: Debian/testing
Python version: 3.12
Browser: Firefox 133.0.3, also Brave 1.73.104

Expected Behavior:

I would like to use the dead space for output.

Perhaps even be able to resize the panes?

Actual Behavior:

It's not usable for reading the code, as shown in screen shot below.

Description

Bug Summary:

I added 3 models to compare their output. The output columns are very narrow, collectively using maybe 1/2 the screen real-estate.

Reproduction Details

Steps to Reproduce:

make sure ollama has some models, I used:

$ ollama list
NAME                                  ID              SIZE      MODIFIED

run using uv tool run open-webui serve
connect with Firefox
add 3 models
ask a question that generates code

generate C++ generic guard class that uses RAII to execute a lambda when the object gets deleted.
implement copy, move, and assignment.
should be hard to read
