[The Dark Side of the Moon Kimi K3 Officially Released: 2.8 Trillion Parameters, Open Source in Ten Days] According to monitoring by Beating Insights, The Dark Side of the Moon has officially released its next-generation flagship model, Kimi K3. The model supports a 1 million token context and can simultaneously process text, images, and videos. It is primarily designed for long-term programming, research, and knowledge work. K3 boasts a total of 2.8 trillion parameters and adopts a mixture-of-experts architecture, activating only 16 out of 896 experts per run. The Dark Side of the Moon claims this is the first 3-trillion-level open model. Official evaluations show that K3 outperforms Claude Opus 4.8 and GPT-5.5 in certain programming and Agent tests.

The full weights are scheduled for release no later than July 27. [Original Link]
