Currently there's only an option to link your OpenAI account to use ChatGPT within Xcode on MacOS 26 Beta. Apparently with other services like Claude you can specify which model you'd like to use, but there's no such option for ChatGPT.
Is this coming, or is this working as designed?
Hi @Dreamwieber,
If you'd like to add OpenAI or another supported third party LLM as a model provider you can do so in the Intelligence tab in Xcode's Settings. You'll need to provide an API key which will likely need to be generated in your account on the model provider's website.
Once the model provider is added, click the top left icon in the Coding Assistant tab and navigate the menus to select the specific model you'd like to use.
Testing today on June 11 2025, I see dozens of options after adding OpenAI as a provider, from GPT 4o mini to 3.5 turbo and many more.
Let me know if you have any issues or further question!
