Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Other

Open WebUI Version

0.6.26

Ollama Version (if applicable)

No response

Operating System

Hosted on Ubuntu 24.04 and used with Windows 10

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

No Reasoning block is shown.

Actual Behavior

Reasoning block is shown with disabled reasoning and disabled reasoning tag.

Steps to Reproduce

I use the InternS1-FP8 Model, which is a Hybrid Reasoning model.
For the tested model I disable the reasoning by "chat_template_kwargs={"enable_thinking": false}"
But I still get the "thinking" block in OpenwebUI. So I thought I could suppress this with the new feature. But still the same result.

If your inference engine uses "reasoning_content" it'll automatically translate it into above.
