Tracks
Eight tracks take you from no background to how large language models work inside. Follow the route in order, or start wherever matches what you already know.

AI from zero
What AI is, how it learns from examples, and how a chatbot picks its next word.
Start with What is AI, really?
How machines learn
Loss, gradients, and generalization: the loop behind every trained model.
Start with The learning loop
Neural networks
Neurons, layers, and backpropagation, built up one piece at a time.
Builds on How machines learn
Start with Layers are matrix multiplications
Language as vectors
Tokens, embeddings, and similarity: how text becomes geometry.
Builds on How machines learn
Start with Tokens
Transformers and LLMs
Attention, the transformer block, and how large language models are trained.
Builds on Neural networks and Language as vectors
Start with Predicting the next token
Learning by trial and error
Rewards, exploration, and how agents learn to act, from bandits to RLHF.
Builds on How machines learn and Neural networks
Inside the model
Look inside a real language model, watch circuits form, and steer what it says.
Builds on Transformers and LLMs
Frontiers
Diffusion, multimodal models, agents, and reasoning.
