Moonshot AI dropped Kimi K2.7-Code on June 12, 2026 — a 1T-parameter open-weight coding model that costs $0.95/$4.00 per million tokens, roughly 5-7x cheaper than Claude Opus 4.8 and GPT-5.5. Here is the developer read: the real benchmark numbers (and why they are all first-party), a verified cost-per-task comparison the hype guides skip, how to run it via API or locally, and when you should still reach for Claude or GPT.
