Historical Background

Moonshot AI entered the AI arena with its Kimi series, initially launching Kimi K2 with 1.5 trillion parameters. The newer Kimi K3, boasting 2.8 trillion parameters, is marketed as the world’s largest open‑weight model, marking a significant milestone in China’s AI ambitions.
