Chinese AI start-up Moonshot is set to release a large language model with capabilities approaching those of frontier US labs such as Anthropic, as the gap narrows between the two countries on state-of-the-art AI. The Beijing-based group is scheduled to release Kimi K3, China’s largest AI model to date with 2tn-3tn parameters, in the coming days, according to two people familiar with the matter. The number of parameters refers to the size of the model’s neural network, with a higher count generally leading to greater capabilities. Anthropic has not disclosed its models’ parameters, but industry experts speculate Opus 4.8 has 1.5tn-2tn parameters. K3 is expected to exceed the performance of Opus 4.8 by mainstream benchmarks, said the people, who added that it would be freely available to download as a so-called open-weight model.
