# Kimi K3 Reaches Frontier Performance with 2.8 Trillion Parameter Open Model

> Moonshot AI has released Kimi K3 as open weights, a multimodal model with a claimed 2.8 trillion parameters and a context window of one million tokens. On the Artificial Analysis Index it ties for the top spot among open-weights models with a score of 60, and it lands at number five overall on public leaderboards with an 80.3 out of 100, putting it within reach of closed frontier systems. What makes this notable is not just the raw size but the openness. Anyone can download and run K3, which means startups, researchers, and hobbyists get near-frontier capability without paying per token to a closed vendor. The million-token context also opens up work over entire codebases, long documents, or large collections of files in a single pass. K3 is another data point in a striking pattern this year, where several of the strongest open models are coming out of Chinese labs and closing the distance with the best proprietary systems. For anyone building on top of AI, that is good news for cost, control, and choice.
