Moonshot AI launches Kimi K3 with 2.8 trillion parameters and million-token context window
Moonshot AI has launched Kimi K3, a frontier-class open-weights model with 2.8 trillion parameters and 1 million tokens context window. The model introduces new Kimi Delta Attention technology that enables 6.3x faster decoding and 25% higher training efficiency, and is already available on multiple platforms with open-source code promised by July 2026.
WHY IT MATTERS
This represents a significant step for open AI models, with K3 topping several benchmarks and having performance comparable to the best proprietary models. The combination of an enormous context window, multimodal input, and innovative attention mechanisms shifts what's possible for the open-source community.
