Comment on FoundationModels guided generation: empty token masks and severe slowdowns on macOS 27 betas 5, 6 and 7
I am building these apps on an M4 Pro MacBook Pro and M4 Pro Mac mini....so both are AFM 3 Advanced. The only other machine I have that would not run the AFM 3 Advanced model is a MacBook Neo. Not sure on that machine, will it run the AFM Core model? If so I can also test there to see if there are the same errors or not. I will get the requested data and send it in FB shortly, actually about to jump into a meeting with our Apple reps so after that (should be done around noon CST)

Sure give me some time and I will get those. This machine I am running on is a MacBook Pro M4 Pro with 48GB of memory. It is using the AFM 3 Advanced. I have tested this on another M4 Pro Mac mini using AFM 3 Advanced and seeing the same issue. I have not tested this on a Mac that is running anything lower than an M4 or M4 pro. I do have a MacBook Neo that I can run it on, would that be the AFM 3 Core? Or not? I will update the feedback shortly with the details above.
