It runs a Qwen2.5-Coder-0.5B model retrained on about 336,000 key input and screen change records, trimmed to roughly 360 million parameters and quantized to 4 bits at about 208 MB so it fits a WebGPU browser. Edwardson describes it as an experiment, not a practical terminal.","whyItMatters":"WorldTUI is a small, cheap test of the world-model idea outside games: whether a network can hold a consistent screen state it never actually maintains, and where that consistency breaks.","webCardHtml":"\u003cp\u003eEdwardson built it after Genie 3, Google DeepMind\u0026#39;s world-generating AI, drew his interest to systems that predict environmental change from operations. A 3D game was too expensive to train, so he chose a character grid instead. Line-by-line prediction made updates fast but risked contradictions, so he added a pass that verifies and corrects generated lines. On a GeForce RTX 4090, the 95th percentile time for a large screen update fell from 6.7 seconds to 0.87 seconds.\u003c/p\u003e","blueskyPost":"WorldTUI's 360M model predicts screens from keystroke and screen-change pairs, so it imitates a terminal's behavior without the underlying session. The demo is the output, not the commands.","twitterPost":"WorldTUI predicts the screen instead of running the command. The model learns the look of a terminal, not the work behind it.","threadsPost":"WorldTUI's trick is that it never executes anything: the Qwen2.5-Coder-0.5B model at roughly 360 million parameters predicts what the screen would show after a keystroke. What looks like a shell is a learned imitation of one, which is why Edwardson calls it an experiment rather than a practical terminal.","newsletterBlurb":"Simon Edwardson released WorldTUI, a browser terminal where AI generates the screen instead of running commands.
