[Regression] - Custom Models

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When an Open API Key and Override OpenAI Base URL is enabled, one can no longer add models to use. This functionality was working just fine in 1.7.xx

Interestingly enough, the model does show up on the chat drop down, but not in the settings model list.

Steps to Reproduce

Enable Open API Key, enable Override OpenAI Base URL, attempt to add a model, notice the add button remains grey and does not respond to clicks or text.

Expected Behavior

After entering text, add button stores text as model to be called.

Operating System

Windows 10/11

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. I can repro it. I’ll pass it to the team.
