Thanks for comments and feedback. I wrote this post in Korean (my native language) and translated it by LLMs. TBH, I spent more time reviewing the post rather than writing. Sorry that I missed the uncomfortable tone and AI-ish. be more careful next time.

Anyway, even though I tried to use coding agent, it was hard to avoid some dead ends and spent more money than I expected. As a newbie in pre-training, hope this baseline codebase helps people who want to reproduce nanochat in JAX + TPU...

If anyone has any useful experiences when you do similar things, please share in the comments.
