Qwen3.6 27B local vs Opus 4.8, voxel engine in raw C with zero frameworks
Sunday experiment. Same prompt to both. Build a voxel world in plain C. No engine, no game library, no framework, just the compiler. The model does its own chunk meshing, render loop and memory management by hand. Left is Claude Code on Opus 4.8. Right is Qwen3.6 27B local on vLLM, the new NVFP4 quant, 256k context. Ru
