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)

No response

Operating System

Ubuntu 24.04.4 LTS

Browser (if applicable)

No response

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

When sending an image to a vision-capable model, the image should be properly passed to the model so it can analyze or describe the image normally, as it does in version 0.8.11.

Actual Behavior

In version 0.8.12, after uploading/sending an image to the model, the model behaves as if no image was received. The same model and the same image work correctly in version 0.8.11.

Steps to Reproduce

  1. Run Open WebUI version 0.8.12
  2. Select a model that supports image input
  3. Upload or send an image in the chat
  4. Ask the model to describe or analyze the image
  5. Observe that the model does not recognize or process the image
  6. Compare with version 0.8.11, where the same model and image work correctly

I re-tested with v0.8.12 and image vision is now working correctly across all models I tried. I'm not sure why it wasn't working before despite trying multiple models and providers.

I apologize for the noise.
