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

v0.8.8

Ollama Version (if applicable)

0.17.0

Operating System

Windows

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

For a model when a Knowledge is given and Function Calling is set to Native, both features should be considered.

Actual Behavior

The Knowledge is ignored.

Steps to Reproduce

  1. Create a Knowledge
  2. Create a new Model
  3. Set Function Calling to Native
  4. Attach Knowledge to Model.
  5. Create a Prompt that can be answered by the Knowledges context.

-> No information is shown that the Knowledged is searched, and the result from the LLM does not include the correct answer.

Logs & Screenshots

No logs available.

The LLM has to use it's tools to query the knowledge. If it doesn't do that it won't answer your question. This is intended behaviour from native tool calling:

Thank you, but when i attach the Knowledge to the prompt, both are working. It apears that the knowledge is auto-injected in such case.
