Pixel 9A TPU compiler slammed by developer, performance data hidden

Developer mgostIH reports that the Pixel 9A's G4 TPU compiler is so buggy that GPT-assisted debugging repeatedly triggered security warnings, with the SDK under a soft NDA. He found 1x1 convolutions with constant parameters to be the best way to extract matmul performance from the chip.
