Thank you, Ziqiao. I am pretty certain that my content should not bump up against any reasonable guardrails and as I said before, none were being triggered in beta 1 and beta 2. I have reviewed the prompts and they contain only standard HealthKit data and benign instructions. I am attempting to file a report and running into some difficulties but will keep trying.

Hello, Thank you for looking into this. Here are the details you requested: API Triggering the Issue: The error occurs when calling LanguageModelSession.streamResponse(to:) in the FoundationModels framework. This happens consistently in our app since updating to iOS 26 Developer Beta 3. The specific error we receive is FoundationModels.LanguageModelSession.GenerationError error 2. This was working as expected on Beta 2. Please let me know if you need any other information!
