Kimi K2.5 (Reasoning) ranks #57 out of 200 models on the public leaderboard with an overall score of 59.35/100. It does not yet have enough sourced coverage for BenchLM's verified leaderboard. While not a frontier model, it offers specific advantages depending on the use case.
Kimi K2.5 (Reasoning) is a proprietary model with a 128K token context window. It uses explicit chain-of-thought reasoning, which typically improves performance on math and complex reasoning tasks at the cost of higher latency and token usage.
Kimi K2.5 (Reasoning) sits inside the Kimi K2.5 family alongside Kimi K2.5. This profile currently has 27 of 321 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.
Its strongest category is Coding (#41), while its weakest is Agentic (#53). This performance profile makes it particularly well-suited for software development and code generation tasks.
Peer position
Exact provisional scores and ranks for the closest listed peers. A score can appear before a model clears the evidence threshold for a rank, so equal scores can have different rank states.
