What Moonshot AI announced
On 24 Oct 2026, Moonshot AI released Kimi K3.1 Pro — Moonshot's open-weight flagship, service first, weights to follow for chat / coding work. Newest entry in the October release calendar, ahead of the 19 Oct image/video releases. Date note: release calendars listed 23 Oct, while Reuters/ANI reporting dated the announcement 24 Oct — this article uses 24 Oct and notes the difference, rather than hiding it.
Reporting on Moonshot’s announcement describes Kimi K3.1 Pro as a 3-trillion-parameter-class open-weight model with a 1 million-token context window, available on Kimi.ai, Kimi Work, Kimi Code and the Kimi API, with full model weights planned by 4 November 2026. Moonshot is also reported to have removed cyber-related data from training to curb hacking capability, while keeping general coding skill — a deliberate trade-off that explains why its cybersecurity scores lag rivals. Treat those benchmark comparisons as the maker’s reported figures, not as this site’s tests.
What it costs, and who can use it today
Price: Not published in the sources checked — check the official website. Access: General. Availability: Released 24 Oct 2026 in Asia reporting (23 Oct in US reporting; see Sources note on this page). A token, where prices are per million tokens, is roughly part of a word; prices are per million tokens processed, not per message. Open-weight means downloadable weights — check the licence for commercial use, because downloadable does not automatically mean unrestricted.

Sources
Official — Moonshot AI — official website (homepage — announcement page not verified; this link does not by itself verify the launch facts below)
Also checked: ScriptByAI — AI Model Release Calendar, updated 23 Oct 2026 — a calendar or category page verifies date, lab and type only, not price or access.
Official sources are listed first, because a lab’s own announcement or product page is the primary source for price, access and availability. Secondary coverage is listed second, and is never used to upgrade an unverified figure into a settled fact.
