Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.8.12

Ollama Version (if applicable)

N/A

Operating System

Windows 11

Browser (if applicable)

Edge

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using 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 every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

The model should finish running tool calls and providing responses completely.

Actual Behavior

Sometimes the response just stops after a tool call, which is pretty random. It might finish a few tool calls and keep going, then suddenly stop after a random one.

I finally found an example where it stops. For some reason, the AI model (Qwen 3.5 122B-A10B) could analyze other images, but with this one (attached), it finishes read_file and then just stops.

Steps to Reproduce

Use the attached image and ask the model to analyze the image.

My configurations:

  • Open WebUI v0.8.12 (docker) + Open-Terminal v0.11.32 (docker with root user access, multi-user enabled)
  • llama-swap with llama.cpp (b86xx)
  • Qwen3.5-122B-A10B UD IQ4_NL - using Native tool call, context size 150,000
  • No filter enabled.

Logs & Screenshots

Open WebUI docker log doesn't show anything abnormal.
