Anthropic's flagship Claude model, used here to port 3D code across graphics libraries.
OpenAI has quietly rolled out GPT-6.2 Sol in a gray-release, with users reporting a sharp capability jump after being auto-routed to the new model. It can generate a full Three.js 3D interactive scene from a single prompt and bundle it into one HTML file, while debuting atop the latest Artificial Analysis leaderboard as a direct rival to Claude Opus 5.5.
Developer Simon Willison used Claude Opus 5.5 in a standard chat session to port a Three.js 3D scene into dependency-free vanilla JavaScript and WebGL, with both versions rendering successfully. It is an anecdotal hands-on demo showing the model can rewrite 3D graphics code across libraries, but offers no quantitative benchmark or reproducible methodology.
