Summary

Sable proves that an integer-quantized transformer produced a specific sequence, layer by layer, on one GPU.

Sable defines every rounding, normalization, softmax and sampling decision as an integer function and proves the resulting inference trace. The authors report proving 4,096-token runs of 32-billion-parameter models in 84.7 to 121.8 seconds on one RTX PRO 6000 GPU. The proof is not zero-knowledge and is aimed at open-weight models.

Why it matters
