Kimi-k2.5 is Moonshot AI's most versatile and intelligent flagship multimodal model to date. Built with a native multimodal architecture, it deeply integrates visual understanding, logical reasoning, code generation, and Agent task processing capabilities. Compared to its predecessor, K2, the k2.5 model marks a significant breakthrough in Agent automation, supporting over 300 steps of complex tool calling for autonomous data crawling, code execution, and in-depth research report writing. Its unique dual-mode design ("Thinking" and "Non-thinking") allows the model to perform long-horizon reasoning for complex logic while maintaining ultra-fast response speeds for standard conversational tasks.
