Artifacts
An article tells you how something behaves. An artifact hands you the controls and lets you find out. Everything here runs in your browser — no installs, nothing uploaded.
What makes an artifact different from an article
Interactive
Every claim has a control attached. Change the input and watch whether the explanation actually holds.
Visual
Live charts, simulators, and playgrounds instead of a paragraph asking you to imagine a curve.
Self-contained
All the computation happens on your device. No backend, no telemetry, no account.
Live Artifacts
Time & Space Complexity
A first-principles teaching session on asymptotic analysis — Big-O through the Master Theorem. Drag the input size and watch O(n log n) and O(n²) part ways, work through twelve graded examples, and take the formula sheet with you.
- Interactive growth-rate explorer
- Twelve graded worked examples
- Printable formula sheet
The Model Is No Longer the Product
AI engineering is a discipline of orchestration, not training. Run a RAG pipeline with retrieval switched on and off to see what grounding actually buys you, then play the iteration-loop game and diagnose six real-world failures.

- Six-failure diagnosis game
- The application stack, layer by layer
In the Workshop
What's on the bench right now. These go live when the interactive parts actually teach something — not before.
A Qubit You Can Rotate
Drag a state around the Bloch sphere, apply gates by hand, and watch superposition collapse when you measure it.
Attention, Head by Head
Type a sentence and watch each attention head light up over it. See what a head is actually looking at when it fires.
The Quantization Trade-Off
Slide a model from FP16 down to Q4 and watch memory, speed, and answer quality move against each other in real time.
Something You'd Want to Play With?
If there's a concept you've never quite been able to picture, tell us. The ones that are hardest to explain in prose usually make the best artifacts.
