Andrej Karpathy spent 8 years at OpenAI and Tesla
Last week, he packed everything he knows into one free 2-hour lecture

People pay $15K for bootcamps that teach less than this
This lecture is better than most paid AI engineering courses
You probably don't have 2 hours right now
Don't let this disappear from your feed
Watch it
Then read the guide below
