Andrej Karpathy c0dbf1f3ff use COMPUTE_DTYPE-aware cast in Muon polar express step ... The bf16 cast is intentional for speed on Hopper+ GPUs, but should be skipped on other platforms rather than blindly applied. fp16 is unstable here due to its limited exponent range, and fp32 platforms don't benefit from the cast. Now: bf16 when COMPUTE_DTYPE is bf16, no cast otherwise. Inspired by PR #667. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-03-25 20:19:14 +00:00
