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

v0.8.5

Ollama Version (if applicable)

No response

Operating System

linux

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

Since ENABLE_PERSISTENT_CONFIG is false, the application should parse DEFAULT_MODEL_PARAMS on every startup and apply {"function_calling": "native"} as the default state for all compatible models.

Actual Behavior

The setting is ignored. It doesn't appear in the UI's model parameters, and the functionality doesn't trigger as "native" by default.

Steps to Reproduce

  1. Deploy Open WebUI (via Docker or Kubernetes) with the following environment variables explicitly set:
  • name: ENABLE_PERSISTENT_CONFIG
    value: "false"
  • name: DEFAULT_MODEL_PARAMS
    value: '{"function_calling": "native"}'
  1. Check params in UI

Does the DEFAULT_MODEL_PARAMS variable support the function_calling key?
