Analysis
Moonshot's Kimi K3.1 Pro announcement describes a post-trained version of Kimi K3 with a one-million-token context window. The October 23 archive lead points to an official account offering the model through Kimi products and its API, alongside a Highspeed variant.
The important availability distinction is explicit: full model weights are promised by November 4, 2026. Calling a model open-weight in an announcement does not mean those weights are already downloadable. The company also says enterprise administrators must enable access, which is off by default at launch.
Our reading: record hosted access and downloadable weights as separate milestones. Moonshot's reported coding, finance and agent benchmarks can inform evaluation questions, but they do not establish performance on a customer's own tasks.
