Researchers have introduced KAT-Coder-V2.5, an advanced coding agent designed for autonomous operation within software repositories. The model's development focused on overcoming limitations in reproducible environments and verifiable rewards through a novel post-training framework. This framework includes AutoBuilder for reconstructing repositories and KwaiClawEnv for synthesizing tool-use trajectories. KAT-Coder-V2.5 demonstrates strong performance, achieving the top agentic tool-use result on PinchBench and ranking second on repository-level software engineering tasks, closely following Opus 4.8.
