Kimi's open model K3 nears GPT-5.6 Sol and Fable 5 while signaling the end of super cheap Chinese AI

Kimi has announced the launch of K3, a multimodal open-weight model featuring 2.8 trillion parameters and one million tokens of context. In the company's benchmarks, K3 closely approaches Claude Fable 5 and GPT 5.6 Sol, outperforming Opus 4.8 and GLM 5.2 in several instances. The K3 model is significantly more expensive than its predecessor, reflecting a shift in Kimi's pricing strategy. Full weights for the model are expected to be released by July 27, allowing developers access to this advanced technology.
