Unable to use AI with XCode 26.2

I decided to try out XCode 26.2s new AI abilities but I only get a "Your request couldn't be completed". When clicking the details button I get see this error:

InferenceError::unspecifiedUnderlyingError::Error(message: "Unknown parameter: 'tool_call_outputs'.", type: "invalid_request_error", code: Optional("unknown_parameter"), privacyPassRedemptionResponse: nil, userFacingLocalizedErrorMessage: nil)

How do I fix that?
