Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
When using a custom URL/Model for OpenAI, I get the following error whenever Cursor attempts to edit a file:
We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.
The chat works fine up until Cursor tries to apply editing. The same model and provider work fine in other AI tools, such as Roo Code. I do not have any MCP servers enabled. I’m on a pro plan.
Steps to Reproduce
- Set a custom OpenAI Base URL and API key
- Add a custom model and deselect all other models
- Make a request in agent mode with the newly added model selected requesting to apply some code editing

Does this stop you from using Cursor
No - Cursor works, but with this issue
