Bug Report

Description

Bug Summary:
If the OpenAI API endpoint is configured to point to a local OpenAI-like server, the model list is not populated if an API key is not configured.

Steps to Reproduce:

1. Setup open-webui normally
2. Configure an OpenAI-like server (ex: LM Studio)
3. Configure the OpenAI API endpoint to point to the OpenAI-like server using either OPENAI_API_BASE_URL or Admin Panel -> Connections -> OpenAI API
4. Do not configure an API key

Expected Behavior:
The models list should be populated if a request can be made to the models endpoint, regardless of whether or not an API key is provided. At the very least, an error should be displayed if an API key is not configured.

Actual Behavior:
Fetching the OpenAI models list silently fails if an API key is not configured. Observe that sending an authenticated request to /api/models results in an empty list. The models are also unavailable in the UI.

Environment

• Open WebUI Version: v0.3.5
• Ollama (if applicable): (not applicable)

Docker Container Logs:
INFO:apps.openai.main:get_all_models() is printed in the console, indicating that an attempt is being made to request the models list, but the request is not actually performed if the API key is missing (verified via LM Studio logs). The request is performed successfully if the Check Connection button is pressed in the Admin Panel, but the list of models is not retained.
