Ant Group's Lingbo Tech Open-Sources Three LingBot-World 2.0 Models, 1.3B Version Runs Real-Time on a Single GPU

Ant Group's Lingbo Technology in China has open-sourced three more models this week: LingBot-World 2.0 Small (1.3B), LingBot-World 2.0 Bidirectional, and LingBot-World 2.0 Causal Pretrain. The company had already open-sourced the 14B LingBot-World 2.0 model in July.

LingBot-World 2.0 is a real-time interactive world model. It supports continuous generation for hours and can respond to character actions like attacking, archery, casting spells, and shooting, as well as environmental events like snow and rain. With more computing power, it can reach 720P/60FPS HD real-time performance.

The Small version has 1.3B parameters and is designed for consumer-grade single-GPU setups, enabling real-time generation on a single card. This makes it easy for individual developers, university labs, and small teams to try it locally. The Bidirectional version is for training real-time world models, providing high-quality distillation sources. The Causal Pretrain version serves as a causal pre-training base for post-training, evaluation, and scene adaptation.
