Interactive tracks, built around figures you can touch rather than walls of text. Start with the fundamentals, prove them on real projects, then go deep — from the models behind ChatGPT and Claude to machine learning for finance. Free, no account, runs in your browser.
The complete course: from "what is a model" through linear and logistic regression, trees and ensembles, neural networks, CNNs, transformers, and production ML. Every concept is a live, interactive figure.
Put the theory to work. A complete ML roadmap followed by hands-on projects on real datasets — tabular, text, images, time series, and recommenders — each taken from raw data to a working model.
How ChatGPT and Claude actually work. Next-token prediction, tokenization, the Transformer (with a live attention matrix you drive), training at scale, and alignment — RLHF and Constitutional AI. The deep, technical tier.
The production track: prompting and structured outputs, retrieval (RAG), agents and tools, evaluation and observability, guardrails, and the cost and latency work that ships an AI feature.
Credit scoring, fraud detection, market risk and Value-at-Risk, financial time-series, and anti-money-laundering — plus two fintech case studies. Real public datasets, real in-browser math.
Stop reading, start typing. Fill-in-the-blank Python exercises with pandas and scikit-learn running in your browser — from your first print() to gradient descent and k-means from scratch, each checked the instant you run it.
Image, video, and audio generation: VAEs and GANs, diffusion and score-based models, latent diffusion and text-to-image, and how multimodal models see.
MDPs, dynamic programming, Q-learning, policy gradients and deep RL (DQN, PPO), the link to RLHF, and game-playing and agentic systems — with interactive gridworlds.
Linear algebra, calculus and gradients, probability and statistics, optimization, and information theory — the math every other course assumes, in a format built for it.
New to the field or coming back for the hard parts — here's the order we'd take them in.
