Kat Coder 2.5 excels at generating 3D games even under Q4_K_M quantization

A user demonstrated that the local LLM Kat Coder 2.5 successfully generated a fully playable, multi-level 3D Star Fox-inspired game in a single HTML file using Three.js. Notably, the model achieved this while running under a compressed Q4_K_M quantization format, outperforming several other open-source and proprietary models. This showcase highlights the rapid advancement of specialized open-source coding models, proving they can handle complex, multi-layered programming tasks locally on consumer hardware. It demonstrates that highly quantized models can still retain the reasoning capabilities required for sophisticated code generation. The generated game included functional ship controls, multiple enemy types, boss fights, level progression, and a HUD, all structured within a single HTML file. Kat Coder 2.5, which is a fine-tuned model optimized for agentic coding tasks, managed to produce a coherent codebase where other models like Gemini Flash struggled.
