NanoGPT Claims 4-20x Training Speedup, Sets New Record of 5.03 Minutes with FineWeb Val Loss 3.28

Recent developments in open-source research have highlighted significant advancements in training speed for language models. A new paper on NanoGPT claims a training speedup of 4 to 20 times compared to GPT, although initial attempts to reproduce these results have faced challenges due to issues with the baseline. Ongoing debates within the community focus on the effectiveness of various proposed methods for accelerating language model training. A notable benchmark was established by the modded NanoGPT repository, which reduced the training time for a GPT-2 model from 45 minutes to just 5 minutes. The latest achievement in this realm is a new NanoGPT training speed record set by a user, achieving a FineWeb validation loss of 3.28 in just 5.03 minutes, improving upon the previous record of 7.2 minutes. This record was made possible through the implementation of FlexAttention with a large sequence length.
