Hy-Nomas, an AI capable of generating traversable worlds like those in video games, has been released as an open model and can run locally on an RTX 4090.
Tencent, a major Chinese technology company, has released 'Hy-Nomas,' a virtual world model. It generates a virtual world based on user input, allowing for free control of cameras and objects. The model is available as an open-source model and can be run locally.
Hy-Nomas — Interactive World Modeling
Hy-Nomas is a relatively small AI model with 8 billion parameters, capable of outputting 720p, 60-second videos. Unlike simple video generation, it can instruct camera and character movements in multiple turns.
It also supports controls that allow you to move the character using the WASD keys or arrow keys.
