Kimi K2 Turbo Preview

Kimi K2 Turbo Preview is a high-speed variant within the Kimi K2 family, engineered as a fine-tuned MoE language model optimized for agentic tasks, coding, and conversational use cases. Built on a trillion-parameter Mixture-of-Experts architecture with 32 billion active parameters across 384 experts, it inherits the core capabilities of its base model while prioritizing rapid inference. The dramatic speed improvement—delivering up to 40 tokens per second compared to the previous generation's 10 tokens per second—transforms how users interact with long documents and real-time workflows, making it particularly effective for scenarios that demand both deep reasoning and swift response generation.

The speed gains stem from advanced inference optimizations including enhanced dynamic expert routing, refined selection algorithms, and improved parallel processing that collectively reduce routing overhead. As a preview release offering early access to the accelerated MoE variant, it sits at the intersection of preview-stage experimentation and production-ready capability. Its 160K vocabulary size and extended context handling make it well-suited for complex coding tasks, multi-turn agentic workflows, and applications where throughput and responsiveness are critical—positioning it as a practical choice for developers building interactive AI systems that operate across lengthy documents and sustained conversations.
