Pelican on a Bike - Raytracer Edition

Read Original

The article details an experiment using multiple large language models (LLMs) to generate a POV-Ray file that renders a pelican on a bicycle. It compares the outputs, noting common parsing failures and oddities like floating eggs, and describes the iterative debugging process to fix the generated code from models like GPT-5 Codex Mini and Claude Sonnet.
