It scores 69.40% on SWE-bench Verified and one-shotted a playable Star Fox clone, all under an Apache 2.0 license, per r/LocalLLaMA testing.
Why now: The benchmark scores and the Star Fox demo surfaced in the same r/LocalLLaMA thread on July 27, right alongside a comparison to Kimi K3's eight-GPU hardware floor.
Kwaipilot released KAT-Coder-V2.5-Dev, a coding model small enough to run on one consumer GPU, according to a benchmark rundown posted to r/LocalLLaMA.
The model activates only 3 billion of its 35 billion total parameters, built on top of Qwen3.6-35B-A3B, and still posts 69.40% on SWE-bench Verified. That score puts a locally-hostable model within range of benchmarks usually reserved for models that need a rack of GPUs to run.
It also scores 63.00% on a multilingual coding benchmark, 45.96% on SWE-bench Pro, and 41.02% on Terminal-Bench 2.1. It ships with a 262,144-token context window under an Apache 2.0 license, meaning anyone can run it, fine-tune it, or ship it inside a product without asking permission.
One r/LocalLLaMA user ran the model at Q4_K_M quantization and reported it one-shotting a five-level Three.js Star Fox clone with keyboard and mouse controls. That's a single generation producing a playable game. Not a snippet.
The same post compares the release to Kimi K3, which reportedly needs eight B300 GPUs to run and carries a $20 million revenue trigger. KAT-Coder-V2.5-Dev needs neither, which is the whole pitch for anyone picking a coding model to self-host right now.
