Developer Fine-Tunes 360M Model to Simulate a Terminal

A developer fine-tuned a 360M-parameter model, WorldTUI, from Qwen2.5-Coder-0.5B on sessions recorded from real shells inside Docker, having it predict terminal screen changes rather than run a real shell. It can create files, run vim and tmux and play snake; key gains came from self-repair and parallel row decoding, testing whether models maintain a consistent world.
