AI model options in kiro software

Based on the information available, Kiro actually allows you to switch seamlessly between Claude Sonnet 4.0 and 3.7 models within the application. You are not forced to use only Claude Sonnet 4.0. During the Kiro public preview, you can use both of these premium models at no cost (with reasonable limits), which is notable since accessing these models elsewhere typically incurs subscription fees or token-based charges.

The ability to switch between models is a feature of Kiro, so you should be able to select Claude 3.7 Sonnet within the Kiro interface without needing to contact anyone. If you're experiencing difficulties with model selection in Kiro, you might want to check the Kiro documentation or join their community on Discord for assistance, as mentioned in their resources.

Unlike some other AWS services like Amazon Q Developer CLI where you need specific commands to change models, Kiro appears to have built-in functionality to switch between these models directly in the interface.

This is exactly the problem, in their latest update they removed the option to choose between models.
