## Introduction: Kimi-VL — A Compact Yet Powerful Multimodal Vision-Language Model

# Introduction: Kimi-VL — A Compact Yet Powerful Multimodal Vision-Language Model
Moonshot AI's open-source Kimi-VL uses a Mixture of Experts (MoE) architecture, with a total of 16B parameters but only 3B activated during inference. It excels in scenarios such as 128K long context, multimodal reasoning, and agent tasks. Its Thinking version outperforms 70B-scale open-source models on mathematical reasoning benchmarks and even surpasses GPT-4o in some scenarios, providing a new solution for balancing efficiency and performance in multimodal models.

# Background: The Dilemma of Balancing Efficiency and Performance in Multimodal Models
In the field of large multimodal models, a long-standing problem is how to achieve performance close to flagship models with limited computing resources. Kimi-VL's emergence provides an answer: through the MoE architecture, with a configuration of 16B total parameters and 3B activated parameters, it achieves performance that surpasses closed-source flagship models, offering an efficient solution for resource-constrained scenarios.

## Model Architecture: Innovative Design of MoE + Native Vision Encoder

# Model Architecture: Innovative Design of MoE + Native Vision Encoder
Kimi-VL's core architecture consists of three key components:
1. **MoE Language Decoder**: Total parameters 16B, 2.8B activated during inference, reducing cost and latency;
2. **MoonViT Native Resolution Vision Encoder**: Processes native resolution inputs, with the new version supporting 3.2 million pixels (1792×1792);
3. **MLP Projector**: Connects visual and language modalities to enable cross-modal understanding and generation.
