Kimi K2.7-Code Review: Moonshot's Coding-Specialized Open-Weight Model — 30% Fewer Thinking Tokens, But At What Cost?

Kimi K2.7-Code (June 12, 2026) is Moonshot AI's coding-focused open-weight model: same 1T MoE architecture as K2.6, now trained to author implementations directly instead of routing through libraries, and using 30% fewer thinking tokens. The catch: all benchmark improvements are self-reported on Moonshot's proprietary suites, no independent SWE-Bench or LiveCodeBench numbers exist yet, and the price jumped 58% over K2.6. We review what changed, what's unverified, and whether the upgrade is worth it.
