Moonshot AI is reportedly preparing to launch Kimi K3, a massive open-weight model with up to 3 trillion parameters meant to rival Anthropic’s Opus 4.8. The Chinese lab is also raising capital at a $31.5 billion valuation as enterprises increasingly weigh open-weight alternatives against pricey closed models.
Moonshot AI just open-sourced Kimi K2, a 1-trillion parameter MoE model with 32B activated parameters engineered specifically for coding and autonomous agent workflows. It scored 53.7% on LiveCodeBench, comfortably beating DeepSeek-V3 and GPT-4.1, powered by a new MuonClip optimizer that eliminates training instability. Why it matters: High-end agentic intelligence is rapidly shifting from pricey closed APIs to open, dirt-cheap alternatives.
