Hands-on explorations from the AI Unmasked courses. Real models, real math, real API calls. All running in your browser.

Fourier Series · Positional Encoding

Euler's Epicycles

Watch rotating phasors trace a square wave in real time. The same e^(iθ) that drives these circles is the exact math powering positional encodings in every Transformer model: GPT, Gemini, Claude.
