Free guide on scaling LLMs across TPUs and GPUs
Radar: a free online book that explains TPUs, GPUs and the parallelism used in training and inference of LLMs at large scale, with a focus on cost and memory.
According to the Radar page dated 12 November 2026, this is a free online book titled How to Scale Your Model. It explains how TPUs and GPUs work, how large language models run on real hardware, and how training and inference can be parallelized at large scale. The linked page presents the material as a way to demystify LLM scaling. According to the description, the content covers the hardware and parallelism math behind these processes, which makes it useful for estimating cost and memory.
