JST-2 JST-2 is a full-stack physics-native world foundation model that represents scenes as persistent 3D atoms rather than pixels. It generates a 3D scene in about one second for under $0.01, expands worlds in real time from new viewpoints, and produces 3D characters with learned motion from a single image without separate rigging.

“太疯狂了！我用 Opus 5.5 做了一款有完整剧情的动作游戏，只花了一天。 游戏场景长安城全部由 Opus 5.5 生成。 最让我惊喜的是角色制作：只要一张图，PINOC (JST 2) 就能直接生成 3D 角色，骨骼自动绑好，不用做任何额外操作。 豆姐、梁子、老马、提伯、阿迪王这五个角色，先用 Codex 画了卡通形象图，再把图交给 PINOC，就拿到了能直接动起来的 3D 角色。全程没有建模，也没有绑骨骼。 走、跑、冲刺、刺拳、回旋踢、翻滚、被击倒、起身、胜利……这些动作都是从 PINOC 的免费动作库里挑的，直接套到角色身上就能用。也可以自己设计动作，游戏里有个“梁子结算舞蹈”的彩蛋，我直接上传了一段视频到PINOC，直接就给我生成了动作，比想象中的简单太多了！ 制作流程也非常简单，直接分享出来给大家： 1. 让Claude Code设计好游戏规则和风格； 2. 让Codex根据提示词设计好角色图片； 3. 安装PINOC MCP https://t.co/9lcXjMvCcw，让Claude Code通过PINOC MCP生成3D资产，并完成整个游戏的制作。 4. 让Claude不断调整和优化细节、玩法，比如根据场景生成开场动画、用TTS生成语音等等。”
“I had way too much fun building this Lord of the Rings-inspired Rivendell game with ChatGPT Astra + our JST-2 world model. Generating the scenes made it so much easier to build, and so much prettier. Come explore the valley, the Unseen World and the Council!”
“Viggle just launched JST-2, which heavily uses gaussian splatting. I played around creating with their model, with different scenes and characters. It's out today and they have a free tier!”
“Took one full-body photo of myself [where you took it] and gave it to Viggle's JST-2 it rebuilt the room around me in 3D, with a 3D me standing in the middle of it. no 3D software, no scanning, just one photo from my phone then I [walked the camera around myself / looked at the room from behind me / made 3D me dance]. [the detail that got you] memes were fun, but this is me inside an actual 3D world.”

“I’m so proud of what our team has built with JST-2, the world’s first full-stack physics-native world model. Beyond the memes and viral videos, we’ve been building something bigger. Been enjoying the world and been building with it as well - will share some exciting stuff I’ve made with it soon!”
“THIS IS INSANE Viggle just dropped JST-2 and it builds entire worlds in 3D, not pixels. - I gave it one shot of a walnut-panelled living room - JST-2 rebuilt the low sofas, the dappled sunlight, the garden beyond the glass - then I dropped a character in, created his motion from PINOC and walked him through it one frame in. a whole 3D world to walk. this could be a big deal for game devs and small studios prototyping new worlds.”
“Congrats to my UofT labmate @chuhang1122, shooting this video with a broken arm🫡 Amazing to see playable worlds generated so quickly and playable directly on my phone, thanks to an architecture not based on modeling pixels. Quality still can be improved, but we will get there!”
