Overview
Everything you need to know about this AI model, including capabilities, performance, pricing, and technical details.
Kimi / Kimi K3.1 Pro
proKimi K3.1 Pro is Moonshot AI's flagship model and the first in its K3.1 series, released on October 23, 2026. Moonshot calls it its most capable open-weight model in the 3-trillion-parameter class.
Chat with it for long coding projects, financial research, and work across long reports or codebases. It reads images, reasons through problems before it answers, and holds a very large amount of context in view as you work.
It has no built-in web search on Aymo. For tasks that need current information, switch mid-thread to a model with web search, such as Grok 4.7.
Why Kimi K3.1 Pro
