Moonshot K3 targets Opus 4.8 with a $31.5B war chest

moonshot ai is preparing to launch k3, a massive 2-to-3 trillion parameter model reported to perform on par with anthropic's opus 4.8, marking a significant leap for open-weights ai. the launch coincides with a new funding round that would double the company's valuation to $31.5 billion. this escalation challenges the closed-source business model of openai and anthropic by offering a high-performance alternative that enterprises can self-host. as chinese labs like moonshot and deepadvance bridge the performance gap, the industry faces increased pressure to justify the high costs of frontier api access versus self-hosted open-weight deployment.
