Ant Lingbo open-sources LingBot-World 2.0, a real-time interactive world model that runs for an hour without quality loss

蚂蚁灵波开源实时交互世界模型 LingBot-World 2.0

Ant Lingbo released LingBot-World 2.0 as open source, a 14B model under a non-commercial license. It generates 720p/60fps real-time video and supports keyboard-driven movement, combat, jumping, plus text commands to change weather or scenes. In stress tests it ran for a full hour without texture blur or geometry collapse—the team claims it is the only general interactive world model that can sustain hour-long generation. I'd wait for third-party reproduction, but the technical recipe is clear: causal pretraining with a hybrid attention mask to suppress error accumulation, plus distillation to hit real-time inference. SGLang already supports it for deployment.

Why it matters: LingBot-World 2.0 is a 14B open-source world model with 720p/60fps real-time interaction and a claimed one-hour stability — a first among open-source world models. The non-commercial license limits adoption, but the technical specs are solid, hitting all three HKR axes.
