Check Existing Issues

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

Installation Method

Git Clone

Open WebUI Version

latest

Ollama Version (if applicable)

No response

Operating System

ubuntu 22.04

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

Each model instance should maintain independent parameter settings, even if they
reference the same underlying model.

Actual Behavior

All instances of the same model share the same parameter configuration. Modifying
parameters for one instance immediately affects all other instances.

Steps to Reproduce

Go to Admin Settings > Connections
Add an external OpenAI-compatible API connection
Add the same model multiple times (e.g., add "gpt-4" three times)
Try to set different parameters (temperature, top_p, etc.) for each instance
Observe that changing parameters for one instance changes all instances

Logs & Screenshots

i don't find errors

You should use model id prefix.
