Problem Description

Currently, when customizing the ChatGPT address, you need to manually enter the model list, which is troublesome and error-prone, and most of the time it is impossible to know the model list actually supported by the interface.

Solution Description

Call the API standard test interface, add a button to the client interface to support interface verification, obtain the model list supported by the interface, and automatically fill in the client model list.

Alternatives Considered

Usually ChatGPT compatible APIs have test interfaces available.

Additional Context

It can greatly improve user experience and application usability.
