2.88 Trillion Parameter Kimi K3 Largest Open Model is Now Available

Moonshot AI has launched Kimi K3, an open model built on a 2.88 trillion-parameter MoE architecture with a 1-million-token context window.

The model adds native multimodal support and open developer tools, while using licensing meant to enable broad but controlled access.

Moonshot AI says Kimi K3 is highly efficient and benchmarks competitively against leading proprietary frontier models.

The release raises the bar for open-weight AI, combining massive scale, long-context processing, and multimodal capability.
