Learner questions

Who should learn from Andrej Karpathy?

Programmers who want model internals should start here when they need neural networks, backprop, and llm internals. The strongest fit is a learner who wants material in these formats: youtube course, code.

What should I do first?

Watch micrograd, then makemore, then the GPT video. After that, open one related resource below and write down the exact workflow, concept, or implementation pattern you want to apply.

What problem does this help with?

Excellent from-scratch explanations of neural networks and language models. Use this profile when you are comparing educators by topic, level, format, and practical usefulness rather than browsing random AI content.

How do I compare this with other educators?

Compare the skill coverage, the starting recommendation, and the related videos. If you need neural networks, search the directory for that skill and shortlist three profiles before committing to a course, book, or playlist.
