Kimi K3: Open Frontier Intelligence

Kimi K3 is a newly released open-weight frontier AI model with 2.8 trillion parameters and 104 billion active parameters.

It includes native vision support, a 1-million-token context window, and new attention plus MoE training methods.

The model was post-trained with reinforcement learning for reasoning, coding, and agentic tasks, and its full weights are now public.

Its strong results on long-context, coding, reasoning, and vision tasks could accelerate research and deployment of advanced AI systems.
