System One models never write text: you give them a state and typed questions, and they return a probability for each possible answer. Fast and cheap for routing and classification at volume, with confidence you can only trust at the very top.
World models skip text and learn the world from raw video, building each frame live from your last move. One prompt becomes explorable 3D: stunning for games and film, still guessing at the physics.
AI coding agents flood the model's context with junk: verbose tool output, the same file read five times. Token optimizers strip it before it hits the model. Cheaper, faster, less dumb.
Problem: Most async workflows are held together with queues, retries, cron jobs, and hope. Durable workflows are the abstraction trying to replace that mess.
Solution: Durable workflows let you write long-running, multi-step workflows as normal code. They handle crashes, retries, waits
