The definitions of `B, T, C `

https://github.com/karpathy/minGPT/blob/4050db60409b5bbaaa3302cee1e49847fc145c65/mingpt/model.py#L62

and referred from http://jalammar.github.io/illustrated-gpt2/

I am remain confused about the definitions of `B, T, C = x.size()`.

vocabulary length, batch_size, and tokenizer size, etc?

Thanks.

Start with mingpt/model.py at line 62 and compare the surrounding code with the linked Illustrated GPT-2 article. Determine what clarification the project should provide for the three dimensions, then document the definitions in the appropriate location and verify that the wording matches how x.size() is used.
