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

Git Clone

Open WebUI Version

v0.7.2

Ollama Version (if applicable)

latest

Operating System

Win11

Browser (if applicable)

Edge/Zen

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

Autocomplete should start after users request:
Help me [complete here]

Actual Behavior

With GPT:OSS
The autocomplete also repeats user request:
Help me [help me [actual completion]]

Other models do not have issues with autocomplete.

Steps to Reproduce

1.Star a new chat with gpt:oss20b and try autocomplete

@silentoplayz commented on GitHub (Jan 18, 2026):

Open WebUI's autocompletion feature:

  • Does not detect if a model is a "reasoning" or "thinking" model.
  • Does not alter autocomplete behavior based on model type.
  • Does not use different completion strategies for reasoning models.

The only model-related checks in the chat input are for capabilities like vision, web search, and image generation, but these affect UI buttons, not autocomplete.

Related reasoning features that exist independently:

  • reasoning_effort parameter control
  • reasoning_tags configuration (Default/Enabled/Disabled/Custom)
  • think parameter for Ollama models

But these are passed through to the model independently and do not influence how autocomplete works.
