kimi-k2-turbo-preview

The Kimi K2 Turbo Preview is a high-speed version of the Kimi K2 series model launched by Moonshot AI. Its core positioning is **“a revolutionary speed upgrade while maintaining powerful reasoning capabilities at the trillion-parameter scale,”** aiming to fundamentally address the longstanding challenge of balancing large-model performance with inference speed.

• A 4x Speed Revolution: The output speed has significantly increased from 10 tokens per second in the original version to 40 tokens per second, representing a 300% boost. This makes real-time AI interactions, long-text generation, and complex logical reasoning exceptionally smooth.
• Trillion-Parameter Scale Retained: While achieving extreme acceleration, the model still maintains a total parameter scale of 1T (1 trillion) and 32B active parameters. It adopts a 384-expert mixture-of-experts (MoE) architecture, ensuring that the reasoning depth remains fully consistent with the original Kimi K2 model.
• Ultra-Long Context Support: Continuing the Kimi family’s strength, it supports a context length of 256K tokens, effortlessly handling long-document analysis, large-scale codebase reviews, and multi-turn complex dialogues.
• Advanced Reasoning Optimization Techniques: Through dynamic expert routing enhancement (reducing computational overhead), memory-access optimization (improving cache efficiency), and computation-graph simplification, the model achieves a dramatic leap in throughput without sacrificing output quality.
• Seamless Integration and Replacement: It remains fully compatible with the original Kimi K2’s API, allowing developers to upgrade directly without modifying their code. Additionally, during specific promotional periods, it offers a cost-effective tiered pricing strategy.
