What it does
Tiny-Universe is a hands-on guide, written in Chinese, that walks through building the main parts of a large language model system by hand, rather than using ready-made toolkits.
Lessons cover a tiny image generator, how the Qwen model works, pre-training a small Llama-style model, evaluation, RAG, a minimal agent, the Transformer and GraphRAG.
It is aimed at learners who already know some deep learning and want to understand what happens inside.
Who it's for
Chinese-speaking students and developers with some deep learning background.
