My WebGPU path tracer is open source! ๐
Physically based rendering, running right in your browser. MIT licensed.
- WebGPU compute shader path tracing, with WebGL 2 fallback
- Two-level BVH built using parallel Web Workers, based on TinyBVH. A 4.6M-triangle scene's BVH builds in just 0.5s on my M4 Max
- Clean results from just a few samples with OIDN denoising
- OpenPBR 1.1 materials
- Physical camera with f-stop depth of field, AgX tone mapping, and bloom
- Drop-in Three.js scene synchronization

DeepSeek V4.1 Flash 1017 is the first open-weight model I've tried that feels this fucking close to Opus at Blender + Three.js.
It made this video ๐
We have measured intelligence. Now it's time to see it.
We are launching AA-3D, our new benchmark for how well AI models build interactive 3D scenes. Each model works as an agent in an offline sandbox and turns a written brief into a three.js web page. A human panel of judges compares pairs of scenes built from the same brief without knowing which model made which.
AA-3D details:
โค 55 written briefs across seven domains, including landmarks, machines, living bodies, games, and space. Each brief says what the scene must show and how people should interact with it, and leaves the rest to the model
โค Each model gets up to three hours and 250 turns. Its sandbox has Blender, Rapier physics, Python, a headless browser to test its own work, and a CC0 library of materials, 3D models, and characters
โค Panelists spend at least 30 seconds with each scene before they vote. One comparison in every four is a validation check
โค Over 10,000 counted votes from over 1,000 panelists rank 21 models by Elo, with 95% confidence intervals
Key findings:
โค Four models are statistically tied at the top: Claude Sonnet 5.5 (1194), Claude Opus 5.5 (1190), GPT-6 Astra (1165), and Claude Fable 5.1 (1131). The 95% confidence intervals of the other three overlap Claude Sonnet 5.5's
โค AA-3D Elo rises with intelligence: each point on the Artificial Analysis Intelligence Index is worth about 18 Elo (Pearson 0.92)
โค The best-placed open weights models, Kimi K3 (982) and MiMo-V2.6-Pro (977), rank 11th and 12th, more than 200 points behind first place
โค A scene costs $0.20 to $32.08, depending on the model. The cheapest, GPT-6 Luna, ranks eighth
More results, more scenes, and how AA-3D works follow in the thread below.
