Harnessing the Universal Geometry of Embeddings

Hands-On Large Language Models (O'Reilly book) — If the idea of universal structure hiding inside text embeddings intrigues you, this O'Reilly guide by Jay Alammar and Maarten Grootendorst walks through how embeddings, tokenization, and language models actually work with hands-on code. It's a great way to go from reading research posts to experimenting with vector representations yourself.
