Viggle JST-2
World model for 3D splat scenes, characters and motion
- Best for
- Game developers who want fast 3D splat scenes, animation-ready characters and text or video mocap to prototype with
- Makes
- 3D Gaussian splat scenes and characters, and full-body motion exported as FBX, GLB or USDZ
- Made by
- Viggle
- Where you use it
- Web
- Engines
- Unity, Unreal Engine
- Pricing
- Free to try in PINOC (60 one-time credits). PINOC Starter is $12.99/month or $10.39/month billed annually, and Pro is $39.99/month or $31.99/month billed annually, as of October 2026. The API is pay as you go at $0.01 per credit
- Free plan
- Yes
- Open source
- No
- Export
- Motion exports as FBX or GLB on a 65-bone Mixamo-named skeleton (USDZ too through MCP). Characters and scenes are Gaussian splats (.vsplat, .spz or .ply), not meshes, so they need a splat renderer such as Viggle's Splat Engine, per Viggle's PINOC pages

JST-2 is a world model from Viggle, the company behind the Viggle meme-video app. Rather than generating video frames, it represents a scene as persistent 3D "atoms", which Viggle encodes as Physics-Native Tokens, and decodes them into images or 3D Gaussian splats, a 3D format built from many small, soft colored blobs instead of polygons.
Viggle says one model covers three jobs. It builds 3D scenes from a text prompt or a 360-degree panorama in about one second of inference on an Nvidia B200, against roughly 5 to 6 minutes for Marble on Viggle's chart, and Viggle puts the inference cost below a cent. It can grow a scene view by view using up to 64 views as context, and rebuild a scene from new views. It makes characters from an image or text that animate without a separate rigging step. And it produces full-body motion from text or video.
You reach it through PINOC, Viggle's browser app, the Viggle API, or an MCP server for agents such as Claude Code, Codex and Cursor. PINOC is free to try with 60 credits; paid plans start at $12.99 a month and add commercial use. On the API, a scene from a prompt costs $0.06 (a panorama counts as six $0.01 views), an image-to-character job $0.25, and video-to-motion $0.05 per source second. Motion exports as FBX or GLB, but scenes and characters stay as splats that need a splat renderer.
It suits fast layout and mood sketching more than finished levels: Viggle says scene collisions and object interactions still use rule-based physics, and that it is developing JST-3 to replace them with learned dynamics. The speed figures and comparisons with Meshy, Tripo and others are Viggle's own. AIGamer hasn't tested JST-2.

From Viggle JST-2's own pricing page, checked 29 October 2026. Prices change; check before you buy.
Limitation: Scenes and generated characters are Gaussian splats rather than meshes, so they don't drop into a standard engine pipeline, and Viggle says scene collisions and object interactions still use rule-based physics.
FAQ
Is Viggle JST-2 free?
You can try it free in Viggle's PINOC browser app, which gives 60 credits once and allows one motion and one character export, for personal, evaluation and prototyping use. Commercial use needs Starter ($12.99 a month) or Pro ($39.99 a month), with about 20% off for annual billing, per the PINOC pricing page.
Can I use JST-2 scenes in Unity or Unreal?
Not as ordinary meshes. Viggle says scenes are Gaussian splat files (.spz, or .ply for older ones) that need a splat renderer. Motion clips export as FBX or GLB, which open in Unity, Unreal and Blender.
Can I use JST-2 with Claude Code?
Yes. Viggle's PINOC MCP server lets Claude Code, Codex, Cursor and other MCP clients make characters, motions and scenes, using credits from the same balance as the app.
How much does the JST-2 API cost?
Viggle's API docs say 1 credit costs $0.01 and new accounts get 100 free credits. Scene Model calls cost $0.01 per view each time the model runs, and a panorama counts as 6 views, so a panorama scene from a prompt costs $0.06.
