Moonshot AI has released Kimi K3, described by the company as its most powerful open-source coding model to date. The model is reported to be China’s first open AI model with 2.8 trillion parameters, positioning it among the largest open models available. According to Moonshot AI’s statements cited by outlets, Kimi K3 is designed to perform coding tasks, support knowledge work, and enable multi-media creation.
Both reports frame Kimi K3 as a major step in scaling capabilities, particularly for software development and related tasks. At the same time, at least one source notes that Kimi K3 is still behind some leading models from other developers, including Claude Fable 5 and GPT 5.6 Sol. The coverage emphasizes the model’s open-source nature and its focus on practical work—rather than only benchmark performance—while also acknowledging the competitive landscape in large-scale AI model releases.
