Introduction to Moondream
Build with Moondream
Moondream is a tiny open-source vision AI that brings powerful image understanding to your applications and runs everywhere. Available in two optimized variants—Moondream 2B (3.9GB) for optimal performance and Moondream 0.5B (400MB) for resource-constrained environments—this compact model offers exceptional efficiency with faster inference times and lower computational requirements.
Interact with Moondream using simple, intuitive language without specialized machine learning expertise, making advanced vision AI accessible to developers of all backgrounds. As a vertically integrated model company, we deliver consistent visual understanding across our core capabilities while continuously evolving.

Core Capabilities
Visual Querying
Answer natural language questions about any image with remarkable accuracy. Identify objects, understand relationships, and extract specific information from visual content with detailed responses based on what the model sees.
Rich Image Captioning
Generate detailed descriptions that capture the essence of any image, going beyond simple object identification to convey scene context, relationships, and even subtleties like mood or style—perfect for content management, accessibility, or creative applications.
Object Detection
Identify and locate objects within images with high precision, making it invaluable for applications in retail, inventory management, security, and analytics where understanding what objects are present and their positions is crucial.
Visual Pointing
Refer to precise locations when asked about specific elements in an image, making it ideal for interactive applications where users need to identify or work with specific parts of visual content.
What is Moondream?
Moondream represents a new generation of multimodal AI that seamlessly combines visual perception with language understanding. At its core, Moondream integrates an advanced CLIP-based vision encoder that transforms images into rich feature representations. These visual features are then processed through a specialized projector that converts them into a format the language model can interpret and reason about.
The language model component has been meticulously optimized for visual understanding, enabling Moondream to perceive images with remarkable clarity and communicate about them using natural language. This architecture allows Moondream to process both text and images as unified inputs, perform sophisticated visual reasoning tasks, and generate detailed textual responses about visual content.
Technical Architecture
Moondream's architecture consists of three primary components working in harmony: a CLIP-based vision encoder that captures visual information, a specialized projector that translates visual features into language tokens, and a powerful language model optimized specifically for visual understanding and reasoning.
Solutions
As a vertically integrated AI company, we regularly roll out new capabilities that extend beyond the core features. Our development roadmap continuously expands what Moondream can do:
Gaze Detection
Shipped
Analyze where people in images are looking, enabling applications that understand visual attention patterns, user focus points, and interpersonal dynamics through gaze direction.
Semantic Visual Embeddings
Upcoming
Generate vector embeddings for specific visual concepts (like "nose" or "wheel"), allowing for sophisticated similarity matching, visual search applications, and fine-grained content organization.
Image Segmentation
Upcoming
Promptable (by word or point) image segmentation that returns pixel-level masks, enabling precise object isolation, background removal, and targeted visual analysis for applications like fashion, retail, and image editing.
Depth Estimation
Upcoming
Promptable depth estimation (by word or point) that enables understanding of spatial relationships in images, creating 3D representations from 2D images, and enhancing AR/VR applications with accurate depth perception.
Semantic Image Diffs
Upcoming
Automatically identify and describe differences between two visually similar images with detailed semantic explanations, perfect for UI testing, quality control, and detecting subtle changes in visual content.
More Coming Soon
Roadmap
We are constantly working on new features like promptable image embeddings (by word or point) and other enhancements to expand Moondream's capabilities. Stay connected with our community to learn about the latest features as they're released.
