Kimi-K2.6 is now live in the Arena, and it’s a big improvement over Kimi-K2.5: - #2 open model in Code Arena (#6 overall), on par with Claude Sonnet 4.6 - #1 open model in Vision Arena (#15 overall) - #1 open model in Document Arena (#8 overall) - #2 open model in Text Arena (#24 overall) Strong gains across agentic coding, vision, and long-context document tasks - pushing the frontier for open models. Huge congrats to the

team!
