Amazon Nova 2 Lite detects objects via text prompts, no training needed
No data pipelines, no ML team—just a prompt and you get bounding boxes.
Amazon Nova 2 Lite, the latest multimodal foundation model on Amazon Bedrock, turns object detection into a simple text-based task. Traditional computer vision requires heavy upfront investment in data pipelines, model training, and infrastructure. Nova 2 Lite eliminates all that—just send an image and a prompt like “vehicle,” “person,” or “dent,” and the model returns precise bounding box coordinates in JSON format. This makes advanced CV accessible to small teams without ML expertise.
The solution uses a four-step pipeline: prompt engineering, Bedrock inference, coordinate conversion (from 0–1000 normalized scale to pixel values), and visualization. Costs are negligible—around $0.0003 per thousand input tokens and $0.0025 per thousand output tokens, meaning 10,000 images run for about $5.69. The model supports zero-shot detection, handles multiple object categories in one call, and can be deployed in hours using AWS Lambda and API Gateway. Use cases span manufacturing defect detection, agricultural monitoring, and logistics item tracking.
- Zero-training object detection: specify objects like 'vehicle' or 'dent' via text, and Nova returns bounding boxes in JSON.
- Cost efficient: ~$0.000069 per image for input tokens and ~$0.0005 per image for output tokens; 10,000 images cost ~$5.69.
- Deployable in hours using Amazon Bedrock, Lambda, and API Gateway—no ML infrastructure or dedicated team required.
