- [Andrej Karpathy — Neural Networks: Zero to Hero](<https://www.youtube.com/playlist?list=PLAqhIrjkxbuWI23v9cThsA9GvCAUhRvKZ>) — The foundational course. Free, ~10 hours, you build a GPT from scratch by the end.
- [fast.ai — Practical Deep Learning for Coders](<https://course.fast.ai>) — Top-down, hands-on, deeply pragmatic. Free. Best second course after Karpathy.
- [Hugging Face — NLP Course](<https://huggingface.co/learn/nlp-course>) — The best free path into transformers if you want to skip most of the math.
- [Anthropic — Prompt Engineering Interactive Tutorial](<https://github.com/anthropics/prompt-engineering-interactive-tutorial>) — Free Jupyter-style course. Best prompting reference I've used — Claude-flavored but transfers.
- [DeepLearning.AI — Short Courses](<https://www.deeplearning.ai/short-courses/>) — Free 1-hour courses on RAG, agents, evals, function calling. Snackable.
- [LangChain Academy](<https://academy.langchain.com>) — Free. Slower-paced. Good if you want to ship something using LangGraph soon.
