Hexagon NPU next to GPU FP32: fp16-safe graphs (exact in fp32) and the Android NPU path
Verified signatureThe S256 and S512 graphs (same file names) gain three rewrites that keep fp16 finite and give identical results in fp32: a power-of-two pre-scale in each large LayerNorm (eps scaled by the square), -1e4 attention masks instead of -1e9, and a power of two moved from the GeGLU product into the output projection in layers 11-12. Galaxy S26, LiteRT 2.2.0, 201 rows: NPU (Hexagon v81, JIT) 36.5 ms per question, argmax 81/81, max probability difference 0.0069; GPU FP32 51.9 ms, 0.0014. The Android sample selects GPU, NPU or CPU and packages the Qualcomm libraries through scripts/fetch_npu_libs.sh. Card and SHA256SUMS updated.32f1b84
