Changelog Entry

Description

generateTitle() requires a model ID to perform the title generation. The frontend is sending the chat model, that can be invalid if that model was disabled or removed on the backend. In that case, the endpoint drops the request before testing if the task model is valid and running.

Fixed

Swapped the detection, so, we test for a TASK_MODEL and TASK_MODEL_EXTERNAL first, and then we drop the request is no valid model is found.
backend\open_webui\routers\tasks.py:

    model_id = form_data["model"]

    # Check if the user has a custom task model
    # If the user has a custom task model, use that model
    task_model_id = get_task_model_id(
        model_id,
        request.app.state.config.TASK_MODEL,
        request.app.state.config.TASK_MODEL_EXTERNAL,
        models,
    )

    if task_model_id not in models:
        raise HTTPException(
            status_code=status.HTTP_404_NOT_FOUND,
            detail="Model not found",
        )

Also, backend\open_webui\utils\task.py received a small update (if task_model_id in models) to avoid a hard error if the model_id is invalid:

    if task_model_id in models and models[task_model_id].get("connection_type") == "local":
        if task_model and task_model in models:
            task_model_id = task_model
    else:
        if task_model_external and task_model_external in models:
            task_model_id = task_model_external
