vork is a 3D and VFX engine built for AI agents.
Agents write the whole scene as code, including their own shaders, materials,
cameras and physics, and vork renders it on the GPU. The core API fits in about
2,500 tokens.

One million birds, each on its own path. 192 frames at 1080p rendered in
97 seconds on a single NVIDIA L4. Blender EEVEE at the same sample count is
projected at 13–18 minutes. How we measured ·

- Built for agents: a small API that agents can extend with their own GPU programs.
- Fast: 1.1–2.3× faster than EEVEE on default stills and movies, and about 8–11× on the bird flock.
Speed, with the qualifications.
- Native GPU engine: written in Rust and Slang, runs on Vulkan and Metal (Linux, Windows, macOS).
- No GPU needed: render on Voyager's cloud GPUs with vork cloud.
Paste this to your agent
Install vork, then paste:
Run vork init my-shot, read vork help, render a preview and inspect the image.
Refine the camera and lighting before rendering at final quality. Read the
relevant help topic when you need a feature the first page doesn't explain.
vork is written in Rust and Slang, with GPU rendering through Vulkan and Metal.
An agent writes a scene,
renders it, looks at the result and revises the code. There is no editor to drive.
Most creative tools expose controls that a person can operate. An agent can also
write a shader in the middle of a shot. vork gives it geometry, ray queries and
GPU execution, then lets scene programs define materials, cameras, light
propagation, simulation and compositing. Ordinary shots need only scene data;
the programming hooks are there when the shot needs something unusual.
Source-available and free during the research preview.
Start here
After installing vork, create a working project:
vork init my-shot
cd my-shot
vork render scene.json --out render.png
vork help
Open render.png, change a colour or camera position in scene.json, and render
again. The starter uses only bundled sphere, box and grid primitives: no downloads,
no GPU needed to initialize. Use vork init my-shot --language typescript or
--language python for editable scene.ts or scene.py alongside the ready-to-render
JSON. The generated README explains regeneration and SDK requirements. Existing
files are never overwritten. The default std/final profile is warmed by setup; use --profile std/draft for quicker previews.
What you can make
The examples include code, preparation commands and credits. Large downloaded
assets and footage stay outside Git; the recipes fetch them or accept a local path.
The images here are stills from these shots. Keep each credit with its image.
A million simulated agents steered by Slang compute programs, with a camera skimming
through the flock. The camera and nine foreground birds are authored; the simulated
million do not flap. The bird stills above come from the measured four-sample,
denoised skim and reveal movies.

wings, extracted wings for the starling body, resized textures.

adds later relighting and wipes. Real footage + rendered 3D; no generative video.
