Made with JST-2 · Real API outputs
See what the model actually creates: rigged 3D characters from images, movement from text, and spatial environments. Every example below is our own generated output.
01 / Characters + motion
Two original characters. Three generated movements. Mix them, orbit the result, and inspect real-time skeletal animation—not a prerecorded video.
Original source images generated with Qwen; rigged 3D characters extracted by JST-2. No borrowed game characters.
Real generation / Reusable assets
Image → enhanced VSPLAT character with an 86-joint body rig. Text → matching MetaHuman-body animation. The same movement works on both characters without manual rigging here.
Exact motion prompt
A martial artist in a balanced boxing stance performs a controlled left jab, right cross, and left hook combination, then returns to guard. Small deliberate footwork, realistic full body coordination, stay near the starting position.Create your character and motion
These are our actual API outputs, not the reference creator’s assets. Generated anatomy and motion can have artifacts; inspect before production use. The viewer supplies playback and camera controls, not combat rules, collision physics or a finished game.
02 / Spatial environments
Explore the original scene outputs. These environments are separate assets; combining them into a game requires your own application logic.
01 / Nature
Generated through Viggle’s JST-2 scene API. Explore the actual SPZ scene in 3D above. Move a little to inspect depth; larger movements can reveal gaps in generated geometry.

Try this prompt in the studio. Your result will vary.
Make your own worldThese environment examples render original SPZ scene files using WebGL2. Scene data loads only when you choose Explore in 3D; panoramas and downloads remain available without WebGL. Scene generation is separate from character and motion generation above. Generated geometry can contain gaps and artifacts.
Before you choose
JST-2 Studio at jst-2.com is independently operated, not Viggle’s official site. It uses Viggle’s API and charges for a ready-to-use browser workflow. PINOC is Viggle’s own app; the direct API is for building your own integration.
These are separate services and billing balances. Site credits cannot be transferred to PINOC or the developer API. A “credit” does not buy the same thing in each service.
On small screens, scroll the table horizontally to compare all three services.
| What to compare | JST-2 Studio · this site | PINOC · official app | Viggle · direct API |
|---|---|---|---|
| Workflow & tradeoff | Image-to-character, text-to-motion and text-to-scene in one browser workspace, with a library and character + motion preview. No personal API key needed; site pricing includes this convenience. | Viggle’s own character and motion workspace, including video motion capture, rigging and retargeting. Choose it if you want the official app and its tools. | Lower listed generation charges for the tasks below, with more integration control. You manage the API key, requests, job polling, previews and storage yourself. |
| Account & free trial | A site account is required to generate. Signup is free but starts at zero site credits; it does not start a subscription. Public examples are free to browse. | 60 trial credits, once. The Free plan is for personal use, evaluation and prototyping; export limits still apply. | A developer account and API key are required. The API documentation lists 100 free credits ($1.00) for new accounts; these are not site credits or PINOC credits. |
| Payment & generation | 100 site credits / $5.00 · 500 site credits / $20.00 · 1,500 site credits / $50.00One-time packs; purchased credits do not expire. No subscription. Character: 30 site credits. Text motion: 10 for 3–60 seconds. Prompt-to-scene: 6. | Free, Starter and Pro plans. Motion from text or video: 1 PINOC credit per second. Image-to-3D character: from 5 PINOC credits. Paid plans add monthly credits; check the current price and billing period on PINOC’s pricing page. | 1 API credit = $0.01. Enhanced VSPLAT character: 30 credits ($0.30). Text motion: 10 credits ($0.10) flat for 3–60 seconds. Initial prompt panorama scene: 6 credits ($0.06); additional view generation and reconstruction are separate charges. |
| Exports & downloads | VSPLAT characters, GLB/FBX motion and SPZ scenes, as returned by the provider. Previewing or downloading existing results costs no additional site credits. Save exports promptly: provider download links expire. | Free includes 1 motion export and 1 character export. Starter and Pro list unlimited exports. Generation credits and export allowances are different limits. | Export API operations have no separate charge. Your integration retrieves and saves the returned files; signed export URLs expire after 1 hour and can be refreshed through the API. |
| Commercial-use boundary | Buying site credits is not a blanket commercial-rights guarantee. You must have rights to your inputs and check the applicable provider terms and intended use of each output. | Free is restricted to personal use, evaluation and prototyping. Starter and Pro include commercial use, subject to Viggle’s terms and your input rights. | Viggle’s API terms (§25) permit lawful commercial use of API outputs. Input rights, applicable law and the provider’s terms still apply; payment does not clear third-party rights. |
A real purchase example · USD
Starting from a zero balance, buy the smallest site pack, generate one enhanced character from your image and one motion from text, then preview them together and download the available assets.
The allocated amount is a share of the pack price, not a standalone checkout price. It assumes one successful character task and one successful motion task; additional generations use more credits. Pairing a preview does not create a separate rendered video.
The same two generation operations have a listed direct API usage charge of $0.40 before any eligible trial credits. That is not a verified minimum API top-up or a finished integration price. This studio costs more for the browser workflow; the direct API may suit you if you can build and maintain that workflow yourself.
The model, explained
JST-2 puts scenes, characters, and motion into a shared 3D world.
Viggle calls it a physics-native world foundation model. The useful distinction is what the system represents: spatial elements that persist across viewpoints and time, rather than only the visible pixels of a finished video.
Underneath are persistent atoms, or Physics-Native Tokens, carrying position, attributes, and learned dynamics. The model decodes these into 3D Gaussian splats, a representation used to render a scene from different viewpoints.
In this studio, you can generate a character from an image, create a motion from text, and preview the two together in your browser. Scene generation remains available in the same workspace. Export your assets for compatible 3D tools.
Read Viggle’s technical introductionJST-2 supports up to 64 input views for scene inference. A shared spatial representation lets the system work with a scene from multiple angles, rather than treating every view as an unrelated image.
Viggle reports about one second and below $0.01 per scene inference on NVIDIA B200 hardware, excluding network latency. These are model inference figures, not end-to-end speed guarantees or consumer pricing.
Upload a PNG, JPEG or WebP image to generate a rigged VSPLAT character. Preview it in 3D and pair it with a motion from your own library. Inspect the character’s shape and proportions before asking for more complicated movement.
Describe a full-body action and choose a duration from 3 to 60 seconds. Preview the generated motion on its own or apply it to your character. Download MetaHuman-body or Mixamo GLB and FBX exports for compatible tools. Inspect foot contact and balance before using an output in a larger project.

From reading to exploring
Create a character, give it motion, or generate a scene in our independent studio. Viggle’s own PINOC app has a separate account and credits.
Continue with Google or GitHub, then open the studio. Your characters, motions, scenes, and credit transactions belong to your account.
A character uses 30 credits, a motion uses 10, and a scene uses 6. See pricing and purchase availability before generating. Credits are returned when a failure is confirmed; an uncertain outcome is not a confirmed refund.
Start with a clear character image. Generate a motion from a short description, then select both in your library to preview them together. Download the VSPLAT character and GLB/FBX motion when ready. Prefer Viggle’s own app? Open PINOC.
JST-2, without the guesswork.
JST-2 is Viggle’s physics-native world foundation model, announced on October 19, 2026. JST stands for Joint Space-and-Time. It brings scenes, characters, and motion into a shared 3D representation, using persistent atoms called Physics-Native Tokens. These carry position, attributes, and learned dynamics, and are decoded into 3D Gaussian splats.
No. JST-2 Studio is an independent application using Viggle’s API, not an official Viggle website. Create rigged 3D characters from images, motions from text, and 3D scenes using site credits. Viggle processes generation inputs. PINOC and the release imagery belong to their respective owners.
A scene costs 6 site credits, an image-to-character task costs 30, and a text-to-motion task costs 10. Choose a one-time pack: Starter: 100 site credits for $5.00; Creator: 500 site credits for $20.00; Studio: 1,500 site credits for $50.00. Purchased credits never expire, and there is no subscription. Secure checkout is handled by Stripe, and credits are added after payment is verified. No credits are awarded just for registering. Site credits belong to this independent studio and are separate from Viggle API credits. Viggle also offers its own PINOC entry point under its own limits and terms. Research inference costs are not consumer prices.
Yes. This studio uses Viggle’s official API for image-to-character, text-to-motion, and text-to-scene generation. Outputs include rigged VSPLAT characters, GLB/FBX motions, and SPZ scenes. API credentials stay on our server. For direct integration, use Viggle’s developer platform and documentation; their prices and account credits are separate from this site.
The central distinction is representation. A video model produces a sequence of frames; JST-2 represents a scene and its contents in 3D, with motion in the same system. Persistent spatial elements give the model a way to describe a world across viewpoints and time. This does not mean every interaction is physically simulated or that every output will be consistent.
In JST-2, scene collisions and object interactions still use rule-based systems. Viggle describes learned physics for JST-3 as future research. That direction is not a current JST-2 feature, and the announcement should not be read as a release or availability promise for JST-3.
