Learn AI for real.
27 guides in three paths. Each explains the "why", gives a practical method, copyable examples and pitfalls to avoid. Level shown on each.
Understand
What happens inside a model: no formulas, no wrong shortcuts.

IntermediateReasoning models, when to make them think
Reasoning models "think" before answering. How they work, what effort levels are, what they cost in time and money, and when they are really worth it.

AdvancedRAG and embeddings: making AI answer from your documents
How "meaning-based" search works, what embeddings and vector databases are, how to build an assistant that answers from company documents citing sources, and the mistakes that make it unreliable.
13 min→Try it now
At the heart of every chatbot is a game of probabilities.
Pick the next word yourself or let the model generate. Raise the temperature: unlikely choices become possible. That is how, at huge scale, every answer is born.
How an LLM thinks
The model does not "know" the sentence: at each step it scores every possible next word and picks one.
Pick the next word yourself
The sentence as tokens (split and IDs are illustrative)
