Hello everyone,  
I have registered API keys for both Claude and GPT in my Cursor setup. I would like to enable tab completion functionality for these models. Could anyone guide me on how to achieve this? Any specific settings or configurations I need to be aware of?  
Thank you in advance for your help!

Hey, Cursor Tab uses our own model, so unfortunately, you can’t use a different model for this feature, and therefore cannot use an API key for it either!
