A visualization of LLM sampling distributions at different temperature settings, showing probability mass shifting from peaked to flat.

Build a From-Scratch LLM Sampler: Temperature, Top-k/Top-p, and Multinomial Sampling vs. Hugging Face

A hands-on guide to building a from-scratch LLM sampler with temperature scaling, top-k/top-p warping, and multinomial sampling, benchmarked against Hugging Face. Includes runnable code and a roadmap to production.
