Vork engine lets AI agents write shaders with a 2,500-token API

Vork reframes engine design around machine-readable APIs instead of human-centric graphics interfaces, a shift that could reshape how agents handle 3D and VFX work. Builders working on agent pipelines for rendering, simulation or generative content can compare it directly against token costs in Blender or Unreal workflows. It runs on NVIDIA GPUs via Metal and Vulkan, so teams can test it on standard cloud instances.
