Chinese tech giants, AI ‘godmother’ Li Fei-Fei race to seize the edge in world models
Alibaba’s introduction of Happy Oyster model for real-time creation of virtual worlds follows unveiling of Spark 2.0 from Li’s World Labs

Happy Oyster supported two modes of virtual world creation, according to ATH: a directing mode for building a world based on text and image prompts and a wandering mode for exploring that world.
Unlike conventional AI video tools, which generate one-off clips that top out at a dozen seconds or a few minutes, Happy Oyster could generate video clips of up to three minutes showing virtual worlds, the company said. In addition, the model could continuously respond to instructions throughout the generation process, as opposed to the conventional, one-shot AI paradigm, the company said.

The launch came a day after San Francisco-based World Labs, co-founded by Li, a Stanford professor, in early 2024, unveiled Spark 2.0, an open-source 3D Gaussian splatting rendering engine that aims to give even less powerful devices, such as smartphones, the ability to view large-scale and detailed 3D images.
