padding 50257 -> 50304 vocab_size, the nerest multiple of 64. the biggest deal smallest optimization i've made in recent past, about 25% faster. this is because the last layer is a major latency bottleneck consuming about 40% of latency due to the very high channel count.

who needs a dataloader? overlap the prefetching of the next batch with GPU compute, ehiding the data loading latency entirely. this saves about 1ms lol

based on my experiments these biases are indeed not needed. code runs faster, identical results. keeping the option just because it deviates from the gpt-2 setup

ok i tried bringing back original init again and this time it makes a ton of difference and works much better than default. i'm not sure what was different with my earlier experiment where i saw a slight regression. may try to dissect commits later, for now merged the original mingpt init (following gpt-2 paper) as default.

grad clipping seems to slightly speed up training in the beginning but i can't see a big difference later in the training. it costs non-negligeable compute to clip. adding it for now because it is standard, and i think more necessary as the model becomes larger. practitioners may consider turning it off for minor efficiency gains
