Kimi K3.1 Pro

Kimi K3.1 Pro is Moonshot's post-trained successor to Kimi K3. It keeps the 1M-token context window and the native understanding of images and video, and adds Moonshot's latest training for long-horizon coding, agentic knowledge work and research over long documents, with reasoning, function calling and structured outputs. Reach for it where K3 fits today: long-context reasoning and multi-step agent work. Stay on K2.6 for high-volume traffic where the cost per task matters more than the last points of quality.
