8f85b83347 inference time mini-optimization low-hanging fruit ty @jxtps for raising: when we are running inference we can apply lm_head on only the very last token 2023-01-12 06:02:50 +00:00

e21cbf887f meant to set always_save_checkpoint to False instead, so we only write when val improves 2023-01-12 05:47:34 +00:00

bb49751439 oh no nanoGPT is trending quickly explain the character-level functionality I added late last night 2023-01-11 17:11:15 +00:00
Andrej Karpathy
d17350a31d add support for character-level language models, a new character-level shakespeare dataset, a new config file that shows how to train a character-level baby GPT on it, and adjust the sample function to figure out if it should decode with characters or GPT2 bpe tokens. The current implementation is a bit hacky and basically assumes just these two possibilities. In the future we may want to support more general encoders or decoders. 2023-01-11 05:27:19 +00:00

Strip unwanted prefix from state keys when loading model in sample.py
2023-01-04 16:46:32 -08:00
Andrej Karpathy
d562b3e550 shuttling the poor mans configurator aside into its own file and adding it to all of train,sample,bench. because i am leaving args in globals() so i can avoid having to prepend every single variable with an args., i have to exec the configurator and the optional configs. so we're left with something very gross by standard convention but also quite simple and functional. *ducks* 2023-01-05 00:44:35 +00:00
