KKKimi K3Moonshot AIUnverified

Moonshot AI's 2.8 trillion parameter open-weights model with a 1M token context window, aimed at long-horizon coding, knowledge work and reasoning. It ranks first on Arena AI's front-end benchmark (76% vs 63%) and on Next.js evals, and is priced at $3/$15 per million tokens.
