Kimi just open-sourced Kimi K3, a massive 2.8-trillion parameter MoE model featuring native vision understanding and a 1-million-token context window. The team claims a new architecture delivers 2.5x the intelligence per unit of compute, and they are also releasing the full underlying stack, from custom attention kernels to scalable agent infrastructure.
OpenAI CEO Sam Altman is heading to Washington this week to preview the company's next-generation AI models for Trump administration officials and lawmakers. Beyond showcasing new capabilities and worker productivity, Altman faces tough questions on cybersecurity following a recent sandbox escape, as well as rising anxiety over Chinese open-weight models rapidly closing the gap.
White House science advisor Michael Kratsios just accused Moonshot of copying Anthropic's Fable to build its open-weight Kimi K3 model, but AI researchers are skeptical. Experts pointed out that Fable only launched on July 1st, making a two-week distillation and training turnaround virtually impossible, while frontier Chinese labs increasingly rely on reinforcement learning rather than simple fine-tuning.
The Trump administration just accused China's Moonshot AI of secretly distilling Anthropic's top-tier Fable model to build its new 2.8-trillion parameter K3 system, while allegedly tapping Nvidia GB300 chips in Thailand. The Treasury is now weighing trade blacklists and sanctions, though Chinese officials firmly denied the allegations.
U.S. Treasury Secretary Scott Bessent just warned that Washington could sanction Chinese AI firms if their open-source models are caught stealing U.S. intellectual property. The threat lands as Chinese alternatives like Moonshot AI's Kimi K3 increasingly challenge OpenAI and Anthropic. Still, critics like Hugging Face's CEO push back, arguing model distillation is standard practice rather than theft.
The Trump administration is weighing measures to restrict Chinese AI models like Kimi K3, considering Commerce Department entity listings and executive orders. White House AI adviser David Sacks warned the move amounts to regulatory capture favoring an OpenAI and Anthropic duopoly. Why it matters: U.S. companies increasingly rely on cheaper Chinese open-source options as domestic alternatives remain limited.
Moonshot AI is reportedly preparing to launch Kimi K3, a massive open-weight model with up to 3 trillion parameters meant to rival Anthropic’s Opus 4.8. The Chinese lab is also raising capital at a $31.5 billion valuation as enterprises increasingly weigh open-weight alternatives against pricey closed models.
Moonshot AI just unveiled Kimi K3, a 2.8-trillion parameter model claimed as the world's first open 3T-class frontier model. Built on a sparse MoE activating 16 of 896 experts, K3 features native vision, a 1-million-token context window, and high-level autonomous coding skills. Full model weights are set to drop on July 27, 2026.
