❯ Kimi launches K3.1 Pro and Highspeed, with full weights due by November 4

Release and weightsMoonshot launched Kimi K3.1 Pro, a 3T-class open-weight model with a one-million-token context, alongside Highspeed, which it says runs 2–3 times faster. Both are available through Kimi products and its API; full weights are due by November 4, the official blog says.

Longer workflowsPost-training builds on K3, targeting coding, 3D creation, finance and multi-step tool use. Examples include creating editable 3D models from instructions or references and exporting them for printing. Kimi Code users can switch through model selection.

Access stagesThe evaluations are company-reported results. Enterprise administrators must enable access. Hosted use is available now; self-hosting the full weights follows their planned release.

▮ SIGNALWorkflow capability and the actual weight-release date both matter for open-model adoption.
