An r/LocalLLaMA user (183 upvotes, 50 comments) reports Kwaipilot's KAT-Coder 2.5 one-shotting a five-level Three.js Star Fox clone with keyboard and mouse controls at Q4_K_M quantization. The open-weight Dev variant is 35B total / 3B activated, built on Qwen3.6-35B-A3B, Apache 2.0, 262,144-token context, and posts 69.40% on SWE-bench Verified, 63.00% multilingual, 45.96% SWE-bench Pro, 41.02% Terminal-Bench 2.1 — with 5,312 downloads last month. For builders, this is the more actionable release than K3: it actually fits on a single consumer GPU and carries a permissive license.
