What is LingBot-World 2.0?
LingBot-World 2.0, also called LingBot-World Infinity, is the second-generation world model from Robbyant, an embodied-AI company within Ant Group. It turns a single image into a fully interactive world and, according to its developers, keeps that world coherent for an hour or more at a stable 720p and 60 FPS, without the gradual texture decay and drift that limit most models to a minute or two.
It succeeds LingBot-World, released in January 2026, which already offered real-time interaction at 16 FPS with under one second of latency and roughly a minute of memory.
How it stays coherent for so long
LingBot-World 2.0 is built on a causal pretraining paradigm paired with a proprietary attention-masking mechanism the team calls MoBA, which lets the model learn how a world evolves in strict chronological order. That is what keeps its “unbounded interaction horizon” from degrading into the drift that shorter-memory world models eventually hit.
Rich actions, agents and multiplayer
Beyond walking and looking around, characters can attack, shoot arrows, cast spells, jump and glide, with outcomes generated to stay physically plausible. Typed commands can trigger global events: day-night cycles, weather changes, new entities dropped into the scene.
Two built-in agents push the world forward: a Pilot that plans and executes character behaviour, and a Director that introduces new events as the scene unfolds. The model also supports multiple users inside a single persistent world, a first for this category.
How to try it
LingBot-World 2.0 is fully open-sourced on GitHub alongside LingBot-Video, and you can play it in the browser through partners such as Reactor without installing anything.
