Andrej Karpathy	1076f97059	delete autocast, an unnecessary thorn in my side, manage dtypes directly	2026-03-04 23:55:30 +00:00
Alan	124f49be98	Removed redundant qunatization of gradients	2026-02-15 15:41:33 +00:00
Alan	d9678ff0f9	Save FP8 tensors in autograd ctx instead of full-precision inputs ... Store quantized input/weight and their inverse scales in _Float8Matmul ctx to avoid re-quantization in backward and reduce saved-activation memory without changing numerics.	2026-02-15 14:31:54 +00:00
Andrej Karpathy	e569b59f92	delete torchao dependency, create our own exact API-matched version of Float8Linear, document it very well. for some poorly understood reason, the performance is not only ~identical but actually runs 3% faster. despite of it being significantly simpler and much less code. i don't fully understand why/how atm	2026-02-10 18:46:39 +00:00
