Chinese company Moonshot AI has released its newest artificial intelligence model, Kimi K3, for free download, challenging leading AI systems with its advanced capabilities and massive size.

• The Kimi K3 model, boasting 2.8 trillion parameters, is available for anyone to download and use commercially, though running it requires significant hardware investment.
• Key organizations involved include Moonshot AI, with backing from investors like Alibaba, and independent testing firms like Artificial Analysis.
• Despite being free to download, the substantial 1.56TB file size and demanding hardware requirements mean most users will rent access, with Moonshot AI charging $3 per million input tokens and $15 per million output tokens, undercutting some high-end competitors.
