What each one is
Neural Networks: Zero to Hero
Andrej Karpathy's legendary lecture series: you build automatic differentiation, then a language model, then GPT — writing every line yourself, with nothing hidden.
- Widely considered the best deep learning teaching ever made
- You implement backpropagation yourself — it finally clicks
- Ends with a working GPT you wrote line by line
OpenAI Cookbook
A collection of working code recipes for LLM tasks — embeddings, RAG, function calling, evaluation. Written for the OpenAI API, but the patterns apply to any OpenAI-compatible endpoint, including your local models.
- Working code, not pseudo-code
- The patterns work with local models too (Ollama, vLLM)
- Covers evaluation, which most guides skip
Key differences
Neural Networks: Zero to Hero is video course + code, while OpenAI Cookbook is recipes. In short, Neural Networks: Zero to Hero fits the single best way to truly understand deep learning, and OpenAI Cookbook fits copy-paste patterns that actually work.
