I added gpt-4o-128k and claude-3.5-sonnet-200k and enabled the Beta feature for long context chat, and the program does not allow me to toggle the models to enabled, I am able to toggle open router models to on.

Hi @GearUnclear ,

Would you mind sharing a screenshot of `Cursor Settings` \> `Models` where you are attempting to toggle the model on?

(redact any sensitive information that may be on the screen)

Do you have any of your own API keys added to the `Models` area?

Also, please copy paste system info from `Cursor` \> `Help` \> `About`.

See attached! I have an OAI API key, but toggling it on and off does nothing. I have tried restarting the program and reloading the window many times.
