You played with tokens, embeddings, and attention in the Visual Lab. Now go past 'I've seen it' to 'I can reason about cost, limits, and model choice from first principles.'
⚡You shipped with the biggest model "to be safe", the bill is eye-watering, and you still can't say why it's the right one.
LEVEL 1 — REMEMBER · the vocabulary
⚓ ANCHOR · IF YOU ALREADY KNOW
If you've ever called a pure function in a loop, you have the shape: a model maps tokens → a probability for every possible next token; you pick one, append it, and call again. Cost, latency, and context limits all fall out of that one loop.
