CookLLM
AI LargeLanguageModel Training
CookLLM is a hands-on LLM engineering course where you build everything from scratch.
What does CookLLM do?
What is the main use case for CookLLM?
CookLLM helps developers deeply understand and build large language models from scratch. Instead of using black-box APIs, you write every component yourself — BPE tokenizer, transformer architecture, CUDA/Triton GPU kernels, Flash Attention, pretraining pipeline, and post-training (SFT/RLHF) — guided by interactive visualizations that make complex concepts intuitive.
Who is the target audience of cookllm.com?
Software engineers and ML practitioners who want to go beyond surface-level LLM usage. Ideal for developers with Python and basic PyTorch experience who want to understand how LLMs actually work at the systems level — whether transitioning from other AI fields, preparing for ML engineering roles, or simply driven by curiosity to build things from first principles.
What is the cheapest pricing package CookLLM offers?
$39 one-time payment for lifetime access (early bird, 70% off). This includes all current and future chapters, full runnable source code, interactive visualizations, and private GitHub repository access. No subscription — pay once, learn forever.
