Kimi K3 (k3 / k3-256k)
Moderato+Moonshot’s flagship: 2.8 trillion parameters, up to 1M-token context with low/high/max thinking modes; officially described as the first open 3T-class model, stably ahead of Opus 4.8 and GPT 5.5. The new k3-256k gives identical results within 256K at roughly half the consumption (no video input). Unlocked from Moderato.
