Moonshot AI set to launch Kimi K3, a 2.5 trillion-parameter model

Moonshot AI, the Beijing-based startup behind the Kimi series of language models, is poised to release Kimi K3, a model with an estimated 2.5 trillion parameters that insiders say will rival the capabilities of frontier U.S. labs including Anthropic and OpenAI. The launch, expected imminently according to a leaked Moonshot API platform page and industry sources, would mark a new milestone in the rapidly narrowing gap between Chinese and American artificial intelligence.news.aibase+2

A Model Built for the Frontier

Kimi K3 is reported to feature a one-million-token context window and advanced multimodal processing capabilities, far exceeding the 1.6 trillion parameters of DeepSeek V4 Pro. The model builds on the momentum of Moonshot's Kimi K2.7-Code, released in June, which already demonstrated strong performance on agentic coding tasks and cut reasoning token usage by 30 percent compared to its predecessor.devops+1

Moonshot's trajectory has been fueled by aggressive fundraising. The company closed a $2 billion round at a $20 billion valuation in May 2026, making it the fastest Chinese AI company to cross that threshold. That followed a $500 million Series C in late 2024, with backing from Alibaba ↘ 6.72%, Tencent, and IDG.the-decoder+2

Distillation Concerns and Export Controls

The release arrives amid escalating tensions between U.S. and Chinese AI labs. In February, Anthropic accused Moonshot, DeepSeek, and MiniMax of using more than 24,000 fake accounts to distill capabilities from its Claude model, targeting its "most differentiated capabilities: agentic reasoning, tool use, and coding". In June, the White House imposed export controls on Anthropic's most powerful Mythos model after suspicions that a China-linked group had accessed it, forcing Anthropic to temporarily pull the model from the market entirely.techcrunch+2

The Washington Post reported in early July that Anthropic has argued Chinese firms' distillation practices, combined with evasion of chip export controls, have allowed them to close the technology gap faster than anticipated.washingtonpost

Market Shift Underway

The competitive pressure is already reshaping how companies deploy AI. DoorDash ↘ 1.40% co-founder Andy Fang said last week that the company now delegates "lower-level work" to Kimi K2.6 and reserves Anthropic's Fable "for only the hardest work," the Financial Times reported. Coinbase ↘ 4.32% CEO Brian Armstrong similarly noted the exchange is experimenting with Chinese open-weight models as default options. On the OpenRouter platform, Chinese models have accounted for more than 30 percent of U.S. token usage every week since February, peaking at 46 percent.globaltimes+1
