theory → playground → your own GPU
Learn the AI stack by watching it work.
Every lesson pairs real theory with a live experiment: draw a maze and race A* against Dijkstra, train an agent that teaches itself Pac-Man, distil and interrogate an LLM. Nothing is a mock-up — every figure runs live, on your own machine, nothing hidden.
Pick a track
The full ML · AI · DevOps stack is live — 94 interactive lessons across eight tracks, every module ending in a graded self-check.
Mathematical Foundations
Optimization, linear algebra, probability and information theory — the mathematics under every model, told as one story from Gauss to Shannon.
Practitioner's Toolkit
Environments, GPUs and CUDA, vectorization and reproducibility — the professional workbench that makes everything else possible.
Machine Learning
Regression to gradient boosting, clustering to recommenders — watch models fit, overfit and generalise on data you can poke.
Forecasting
Decomposition to Kalman filters to global neural forecasters — time series with the backtesting rigor most tutorials skip.
Deep Learning
Backpropagation by hand up to transformers and diffusion — watch signals propagate, gradients vanish and attention route.
Reinforcement Learning
Search → RL → agentic LLMs: from a maze you draw, through deep RL on your own GPU, to AI agents and their reliability.
LLM Engineering
Tokenisers, attention, scaling laws, RAG and evals — the stack behind every AI product, opened up live in the page.
DevOps & Cloud
Containers, CI/CD, infrastructure as code and cloud deployment (AWS · Azure · GCP) — ship what you build, the way this platform ships itself.

Learn
Every algorithm and method, explained properly — the idea, the math, pseudocode, and when to reach for it.
Read the theory →Play
The practical half. Draw a maze, race the algorithms, train an agent, teach an LLM — and see every result animate live.
Open the playground →Your machine
The playground computes on your GPU via a small worker you run locally. Your models and API keys never leave it.

No account. The theory is free and instant; the playground runs on a worker you download and run.
