README: give an AI agent a small but real LLM training setup and let it experiment autonomously overnight. It modifies the code, trains for 5 minutes, checks if the result improved, keeps…
README: train.py — the single file the agent edits. Contains the full GPT model, optimizer (Muon + AdamW), and training loop.
README: Requirements: A single NVIDIA GPU (tested on H100)
README: The `program.md` file is essentially a super lightweight "skill".
README: prepare.py — fixed constants, one-time data prep (downloads training data, trains a BPE tokenizer), and runtime utilities (dataloader, evaluation).
