Andrej Karpathy$2,000 masterclass. For free
If you donโt know who Andrej Karpathy is, hereโs the short version: he was a founding member of OpenAI, ran AI at Tesla, and now runs his own AI education company. The dude is a literal legend in the space. He just dropped a 3.5 hour video called โDeep Dive into LLMs like ChatGPTโ and itโs free on YouTube. Hereโs why it actually matters for us: Most of us are out here vibe coding, prompting, building stuff, and hoping it works. When it breaks, we donโt really know why. We just try a different prompt and pray. This video fixes that. Itโs not about prompts. Itโs not about tricks. Itโs about understanding the actual machine youโre talking to every single day. He covers: โข How these models actually learn (pretraining) โข Why ChatGPT hallucinates and what to do about it โข Tool use, memory, and how the model โthinksโ โข Why models are weirdly good at hard stuff and weirdly bad at simple stuff (he calls it โjagged intelligenceโ) โข RLHF, AlphaGo, DeepSeek, the whole stack The reason Iโm pushing this so hard: if you understand even the basics of whatโs happening under the hood, your prompts get sharper, your debugging gets faster, and you stop being surprised when Claude messes up the same thing 3 times in a row. You donโt need to be technical. He literally made it for a general audience. Watch it once just to take it in. Watch it twice to actually start applying it.
