Kimi K3.1 PRO Highspeed

Best suited to long-horizon coding, research, and multi-step agent work. The new Kimi Pro series offers roughly a 1-million-token context window and image and video input; thinking is required, making it a fit when deeper reasoning is worth the extra usage.

Moonshot flagship model with native vision and up to a 1M-token context window. It currently runs at max reasoning effort and suits long-horizon coding, knowledge work, and complex tasks that coordinate terminal tools. For stable use, preserve the full reasoning history and start a new session in a compatible agent harness.

Free models are for learning and trial purposes only and may be removed at any time. Premium models have limited quotas with 5 requests per minute, and their availability is not guaranteed.

Built for agents, coding, and long-context tasks, offering more complete multimodal understanding, a million-token context window, and long-horizon reasoning than MiMo V2. Compared with Chinese peers such as Qwen, GLM, and DeepSeek, its strengths are Xiaomi ecosystem fit and engineering automation scenarios.
