Kimi K3.1 Pro launches hosted access before its promised weights release

Moonshot AI offers Kimi K3.1 Pro through its hosted apps, coding tool and API, with a claimed one-million-token context window. A Highspeed variant is also available. Despite the announcement’s open-weight positioning, full weights are promised for November 4 and are not yet the current access path. The company describes expanded post-training across coding and other tasks; its benchmark comparisons remain vendor evaluations.

Why it matters

API availability, usable context and downloadable weights are different capabilities that need separate checks.

More context

Try a bounded API evaluation or select the model in Kimi Code. Enterprise access is off by default until an administrator enables it. Measure task completion and total cost on your own workload. The original page does not display an exact publication date.

Keep in mind

A large context limit does not establish reliable use of every token. Self-hosting requirements and licensing need review when the promised artifacts actually arrive.
