H3-World

Turns the 33B MiniMax-H3 into an interactive world model by converting its existing zero-shot natural-language control of characters and camera into precise, temporally grounded control, without bolting on a dedicated action module. Each action is a structured character-and-camera instruction aligned to video latents, with temporal attention routing confining an instruction to its intended interval so control does not leak across actions. Trained on 8,000 gameplay samples over 10,000 LoRA steps touching 0.199% of parameters, and it still generalises to unseen scenarios. arXiv paper dated 1 September; unrelated to the community Space sharing the name.
