According to BenchLM.ai, Kimi K2.6 ranks #15 out of 119 models on the provisional leaderboard with an overall score of 85/100. It also ranks #9 out of 27 on the verified leaderboard. This places it in the upper tier of AI models, with competitive scores across most benchmark categories.

Kimi K2.6 is a open weight model with a 256K 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.

BenchLM links it directly to Kimi K2.5 as the earlier related model in that lineage. This profile currently has 46 of 223 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 (#7), while its weakest is Multimodal & Grounded (#27). This performance profile makes it particularly well-suited for software development and code generation tasks.
