Developer wizardbrainz had Fable 5.2 port his bespoke CUDA voxel renderer—built on techniques he'd sat on for years and largely absent from training data—to Vulkan. The model made mistakes at first but succeeded, running at 4K on an RTX 5090, though some errors still need manual fixes. The demo shows both the power and limits of frontier coding models on niche low-level graphics code.
