GoKawiilDeveloper fine-tunes 360M model to simulate a Linux terminal
A developer built WorldTUI, a 360-million-parameter model based on Qwen2.5-Coder-0.5B, fine-tuned on recorded terminal sessions from real programs run in Docker. The model has no actual shell or filesystem behind it; it predicts screen changes in response to each keypress, and can simulate file creation, vim, tmux, and even the game snake. A browser demo lets users test it, including typing a misspelled command to reveal it's not a genuine shell.
