Introducing Moondream3 Detect: Natural Language Object Detection Made Simple

Object detection has long been a cornerstone of computer vision, powering everything from autonomous vehicles to retail analytics. But traditional approaches often require extensive training data, complex pipelines, and specialized expertise. Today, we’re excited to announce that Moondream3 Detect is now available on WaveSpeedAI—bringing the power of natural language object detection to developers through a simple, ready-to-use API.

What is Moondream3 Detect?

Moondream3 Detect is a vision-language model that fundamentally reimagines how object detection works. Instead of being limited to predefined categories from training datasets, this model lets you describe what you want to find using plain English. Simply tell it “find the red ball” or “locate all bicycles,” and it returns precise bounding box coordinates for every matching object in your image.

Built on the Moondream3 architecture—a sophisticated mixture-of-experts model with 9 billion total parameters but only 2 billion active during inference—this model delivers frontier-level accuracy while maintaining the speed developers need for production applications. The architecture combines a SigLIP-based vision encoder with multi-crop channel concatenation, enabling token-efficient processing of high-resolution images without sacrificing detail.

Key Features

Natural Language Object Queries Forget rigid class taxonomies. Moondream3 Detect accepts any descriptive text prompt, from simple object names like “person” or “car” to more specific descriptions. This zero-shot capability means you can detect objects the model was never explicitly trained on—a game-changer for specialized applications.

Precise Bounding Box Coordinates Every detection returns normalized coordinates (x_min, y_min, x_max, y_max) ranging from 0 to 1, making it trivial to scale results to any image resolution. The model has shown significant improvements in detection accuracy, particularly for small and distant objects.

Multi-Object Detection Whether your image contains one object or dozens, Moondream3 Detect identifies and localizes all instances matching your query. Each detection is returned in a clean JSON array, ready for immediate processing.

Optimized for Real-World Performance With only 2 billion active parameters during inference, the model runs efficiently without the massive compute requirements of larger vision-language models. This translates directly to faster responses and lower costs for your applications.

Real-World Use Cases

E-Commerce and Retail

Automatically catalog product images by detecting and extracting individual items. Verify shelf placement and inventory levels through visual analysis. Build visual search features that let customers find products by uploading photos.

Robotics and Automation

Enable robots to understand their environment through natural language commands. “Find the package” or “locate the charging station” becomes actionable intelligence for autonomous systems, allowing flexible behavior without constant retraining.

Quality Control and Manufacturing

Detect defects, missing components, or assembly errors in production line images. The model’s ability to understand varied prompts means inspectors can check for different issues without building separate detection models for each case.

Content Moderation and Compliance

Identify specific objects or elements within user-generated content. Whether checking for prohibited items in marketplace listings or ensuring content guidelines are followed, natural language queries provide unprecedented flexibility.

Security and Surveillance

Build smart monitoring systems that can search for specific objects or people based on descriptions. The zero-shot capability means you can adapt to new scenarios instantly without retraining.

Accessibility Applications

Create tools that help visually impaired users understand their surroundings by detecting and describing objects in their environment through simple queries.

Getting Started with WaveSpeedAI

Integrating Moondream3 Detect into your application takes minutes, not days. WaveSpeedAI provides a ready-to-use REST API that eliminates infrastructure complexity entirely.

Simple API Request

{
  "image": "https://your-domain.com/image.jpg",
  "prompt": "person"
}

Clean Response Format

{
  "objects": [
    {
      "x_min": 0.1556,
      "x_max": 0.6881,
      "y_min": 0.2610,
      "y_max": 0.9551
    }
  ]
}

The model supports JPEG, PNG, and WebP formats with images up to 10 MB. For best results with small or distant objects, higher-resolution source images improve detection accuracy.

Why WaveSpeedAI?

No Cold Starts: Your requests are processed immediately, every time. No waiting for instances to spin up or dealing with unpredictable latency spikes.

Affordable Pricing: At just $0.001 per request, Moondream3 Detect makes AI-powered object detection accessible for applications at any scale—from prototypes to production workloads processing millions of images.

Best-in-Class Performance: WaveSpeedAI’s optimized infrastructure ensures you get the fastest possible inference times without managing GPUs or optimizing deployment configurations.

Simple Integration: A clean REST API means you can integrate object detection into any application regardless of your tech stack. No SDKs to install, no dependencies to manage.

Best Practices for Optimal Results

• Use specific, clear object names for the most accurate detections
• Provide higher-resolution images when detecting small or distant objects
• Batch your requests when processing multiple images to maximize throughput
• Normalize coordinates by multiplying by your image dimensions to get pixel-precise bounding boxes
