Moonshot unveils Kimi K3, largest open-weight AI at 2.8T parameters
Moonshot, a Chinese AI startup, just dropped Kimi K3, the biggest open-weight AI model ever, packing a wild 2.8 trillion parameters.
It's built for tricky stuff like deep reasoning and coding, and thanks to its huge 1-million-token context window, it can handle significantly more data than earlier generations of AI models.

Kimi K3 is already making waves by beating OpenAI's GPT-5.6 Sol and GPT-5.5 in GPU optimization, and nearly matching Anthropic's Fable 5.
< em>Arena.ai ranked it top for web interface-building; Vals AI put it second overall.
Backed by Alibaba and Tencent, Moonshot is aiming high, raising $2 billion to hit a $30 billion valuation before a possible Hong Kong IPO.
With China's rapid progress in AI (and rivals like MiniMax planning their own large models), the global race just got a lot more interesting.
