Clear, interactive essays on topics in AI, science, and computing. You don't really understand something until you can play with it.
On April 10, 2026, four astronauts splashed down after the first crewed lunar flyby in over 50 years. Apollo already did this in 1968. Explore what Artemis II actually proved, how Orion works, and why this mission reshapes the next decade of human spaceflight.
Stop hand-tuning prompt strings. DSPy lets you declare what your LM should do, compose calls into pipelines, and compile optimized prompts automatically. Explore signatures, modules, and optimizers interactively.
Give an AI agent a real LLM training setup, go to sleep, wake up to a better model. Explore how Karpathy's autoresearch lets agents run 100 experiments overnight - keeping wins, discarding losses, and steadily improving.
Most coding agents ship with dozens of tools. Pi ships with four - and asks the AI to build the rest. Explore how this minimal agent architecture powers OpenClaw's multi-channel AI platform.
Language models predict the next word. World models predict the next moment. Explore how Google's Genie, LeCun's JEPA, and Fei-Fei Li's World Labs are building AI that understands physical reality.
