Bug Report

Bug Summary:
The "Advanced Params" section of the model creation / edit page has a setting for use_mmap. The options are "default" or "on", but the default is on in my case. Changing this setting does not seem to do anything for my setup.

Steps to Reproduce:
Try to change the setting for use_mmap in the model creation / edit page to off.

Expected Behavior:
use_mmap can be set to off.

Actual Behavior:
use_mmap can only be set to default or on, both of which enable mmap in my case.

Environment

  • Open WebUI Version: v0.3.8

  • Ollama (if applicable): 0.2.1

  • Operating System: Windows 11

  • Browser (if applicable): Edge

Reproduction Details

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.

Installation Method

pip
