Common questions
- What exactly is free?
- Ten full lessons, no account and no card: the opening act (how an LLM thinks, the whole pipeline, words as vectors, embeddings, similarity) plus a free door into next-word prediction, attention, RAG, agents and the GPU lesson. They are complete lessons, not previews.
- Is it a subscription?
- No. The full course is a single one-time payment of $9.99 with lifetime access, including every future lesson and update. There is nothing recurring to cancel.
- What is the free launch pass?
- While the launch lasts, a limited number of free passes unlock the entire course at no cost. Claiming one takes a Google sign-in and nothing else, no card. When they run out, the one-time purchase remains.
- What if it is not for me?
- There is a 30-day money-back guarantee on the purchase, and the ten free lessons exist precisely so you can judge the real thing before paying anything.
- Do I need math or coding?
- No. Every lesson is a visual, hands-on widget you operate in the browser: you predict what will happen, then the mechanism shows you. No code is written and no math background is assumed.
- Is the course available in Spanish?
- Yes, the whole course and every explainer ship in English and Spanish. The language selector is in the header, and Spanish pages live under /es.
Not sure yet? Read a plain-language explainer or take the 10-question diagnostic, both free.
