Kimi’s model development demonstrates a clear technological progression path, with four current model lines each offering unique characteristics to address different application scenarios.

The Kimi K2 Series, as the newest flagship model, adopts an innovative Mixture-of-Experts (MoE) architecture with a total parameter count reaching 1 trillion, while activating 32 billion parameters per inference. This design significantly enhances complex task processing capabilities while maintaining efficient reasoning. Notably, the “turbo-preview” version within the K2 series has been specifically optimized for response speed, showing particularly outstanding performance in code generation and multi-step task planning scenarios. Developer community tests indicate a 27% improvement in Python code first-pass accuracy compared to previous generations.

The Moonshot-v1 Series utilizes a traditional dense architecture, offering three context length options (8k, 32k, and 128k) to accommodate diverse needs from daily conversations to long-form text processing. The vision-preview version adds image comprehension capabilities, enabling it to handle Q&A scenarios involving simple charts and diagrams. While its performance doesn’t match the K2 series, its stable output and flexible configuration options make it the preferred choice for many enterprise API integrations.

Kimi-latest serves as a special “dynamic pointer” model that automatically aligns with the current most stable production version. For developers who prefer not to frequently switch model versions, this provides the most worry-free option. The model defaults to 128k context length and features an automatic caching mechanism that significantly reduces token consumption for long-text processing.

k0-math is a specialized vertical model optimized for mathematical reasoning, employing a training approach that deeply integrates reinforcement learning with chain-of-thought techniques. While the official specifications haven’t been disclosed, tests on the international mathematical reasoning benchmark MATH show its problem-solving accuracy exceeds that of general-purpose models by over 40%, making it particularly suitable for educational tutoring and scientific computing scenarios.
