 # makemore
 
-makemore is the most accessible way of tinkering with a GPT.
+makemore takes one text file as input, where each line is assumed to be one training thing, and generates more things like it. Under the hood, it is an autoregressive character-level language model, with a wide choice of models from bigrams all the way to a Transformer (exactly as seen in GPT). For example, we can feed it a database of names, and makemore will generate cool baby name ideas that all sound name-like, but are not already existing names. Or if we feed it a database of company names then we can generate new ideas for a name of a company. Or we can just feed it valid scrabble words and generate english-like babble.

-Training progress and logs and model will all be saved to the working directory `names`. The default model is a super tiny 200K param transformer; Many more training configurations are available - see the argparse and read the code. Training does not require any special hardware, it runs on my Macbook Air and will run on anything else, but if you have a GPU then training will fly. As training progresses the script will print some samples throughout. However, if you'd like to sample manually, you can use the `--sample-only` flag, e.g. in a separate terminal do:
