360M Parameter World Model Simulates Terminal via Character Grid Prediction
October 21, 2026
A 360M-parameter model predicts terminal screen changes based on keypress inputs without a backend shell or filesystem. The model uses parallel row decoding and self-repair mechanisms to simulate environments like vim, tmux, and snake directly in a browser via WebGPU.

researcherThis demonstrates how character-grid prediction can serve as a scaled-down alternative to pixel-based world models.
