Kimi iterates a 3-trillion-parameter large model, launching its first Pro version model

According to Caixin Online, in the early hours of October 24, Moonshot AI (Kimi) officially launched Kimi K3.1 Pro. Kimi said that Kimi K3.1 Pro is a post-training version of Kimi K3 and its most capable 3-trillion-level parameter model to date, supporting a 1-million-token context, with particularly notable improvements in coding, 3D creation, financial research and other long-horizon Agent capabilities. Recently, domestic models have successively released Flash-level models to capture the cost-effectiveness market. Kimi has also, for the first time, introduced a Pro model in its model versions, saying this is the first model in the K3.1 series, leaving room for the release of cost-effective models.
