Demystifying Transformers: A Pure Linear Algebra Guide to LLMs
theomitsa · x · 2026-08-03
Recommends a comprehensive guide that dives into the underlying principles of Transformers. Unlike many tutorials that treat LLMs as magic black boxes, this material strips away software engineering fluff and explains what models are actually doing using pure linear algebra.
It provides exact mathematical formulations for attention mechanisms, tokenization, and KV caching. It's a must-read for anyone wanting to understand the rigorous math making large language models tick rather than just calling APIs.
