Moonshot AI

Moonshot AI is the Beijing lab whose assistant ships under the Kimi name, and the homepage in October 2026 leads with Kimi K3 rather than the K2 open-weight model this entry was originally written around: the site describes K3 as 2.8 trillion parameters, natively multimodal, with a million-token context, aimed at long-horizon coding, knowledge work and deep reasoning. Around the assistant it lists deep research, one-click website building, table generation and self-directed editing of PPT decks, plus AI Agent and an agent cluster, Kimi Code, an open platform and an enterprise edition. The company still presents itself as Moonshot AI (Beijing Moonshot Technology), and the research list runs from K2.6 in April 2026 to K3 in July 2026.

It suits people who want a general assistant that reads very large inputs in one pass and who are content working in Chinese or English: the app is offered for iOS, Android, macOS and Windows with a browser plugin, and an open platform and API sit behind the consumer product. It suits less well anyone who needs the open weights specifically: the homepage now puts the proprietary flagship first, and the figure the site gives is a million-token context for K3 rather than the two million tokens this entry previously quoted.

Not verified: no pricing page was opened, so no cost and no tier is quoted here — the site does link a pricing page, which was not read. Nothing was run or tested, so the context length, the parameter count and the benchmark standing are the vendor's own descriptions. Whether K3 or K2.6 weights are published under an open licence was not confirmed on this pass, and the older claim that K2 was open-weight was not re-checked. Availability outside China and the behaviour of the agent cluster were not examined.
