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
Prompt Engineering Guide
DAIR.AI's comprehensive guide to prompt engineering: techniques, patterns, risks, and the research papers behind each of them — not folk wisdom.
- Every technique is backed by a paper
- Covers adversarial prompting and risks
- Available in many languages
