Claude opus 5.5 enables real-time ray tracing in just one hour

A Reddit user has demonstrated that Claude Opus 5.5, an AI model developed by Anthropic, can generate a real-time hardware-accelerated path tracer in approximately one hour. The system, which leverages NVIDIA’s OptiX 9.1 and CUDA RTX and Blackwell kernels, was built using two RTX 5090 GPUs and supports complex lighting effects such as diffuse, metallic, and self-illumination. The project, which runs at 34 FPS with 267 million rays per second, utilizes advanced techniques like Shader Execution Reordering and Multiple Importance Sampling. The user’s initial prompt requested a fully functional ray tracing demo, and the resulting code was capable of rendering across two GPUs using a multi-adapter pipeline. Tech media Wccftech highlighted that the tool is accessible even to those without deep expertise in graphics APIs or shader compilation.
