Moonshot AI released Kimi K3, described as the world's largest open 3T-class model with 2.8 trillion parameters. It features native vision, a 1 million token context window, and strong performance on long-horizon tasks. The model completed computational astrophysics research in two hours that normally takes experienced researchers one to two weeks. It reviewed papers, implemented pipelines, evaluated equations, and generated interactive dashboards. Kimi K3 also optimized GPU kernels, built compilers, and designed prototype chips using open tools. It uses advanced architectures for better scaling efficiency. The model still trails top proprietary systems like Claude Fable 5 and GPT-5.6 Sol overall but shows competitive results in coding and agentic workflows. Full weights release is expected soon, making it accessible for self-hosting. This advances China's push in frontier AI capabilities.
