Kat Coder 2.5 is insane. Especially considering I ran it at Q4_K_M

I tested Kat Coder 2.5 with this prompt: Create a spaceship game inspired by Star Fox using vanilla Three.js and HTML. It should have at least five levels, keyboard and mouse controls, enemies, and a fully functional gameplay system. The result surprised me. It generated a genuinely playable game with ship controls, multiple enemy types, different weapons, bosses, level progression, a HUD, visual effects, and a fairly well organized codebase, all inside a single HTML file. Kat Coder 2.5 is derived from Qwen 3.6 35B A3B, but in my tests it consistently produced much better results. I also tried it with 3D scenes, dashboards, and logic heavy coding tasks, and it performed very well across all of them. The Star Fox test was where the difference became obvious. None of the other open source models I tested managed to execute the idea properly. Even models like Gemini 3.6 Flash Extended struggled to produce something coherent and actually playable. What makes it even more impressive is that I ran Kat Coder 2.5 using a Q4_K_M quantization. plunker code : https://plnkr.co/plunk/Sc7yFCPPdrBWvkA7 submitted by /u/ConfidentDinner6648 [link] [comments]
