1. Tutorial Introduction

Moondream3, proposed by the Moondream team in September 2025, is a visual language model based on a hybrid expert architecture, boasting 9 billion parameters (2 billion of which are activation parameters). This model provides state-of-the-art visual inference capabilities, supports a maximum context length of 32K, and can efficiently process high-resolution images. Moondream3 employs innovative MoE FFN and SigLIP visual encoders, making it suitable for tasks such as image question answering, image annotation, and object detection.
