> Human-in-the-loop data annotation, validation, and model evaluation services for computer vision, NLP, and multimodal AI.

Sama provides human-verified data annotation, validation, and model evaluation services for AI teams. According to the company, it combines automation with expert human annotators for computer vision, NLP, and multimodal AI. The company's website lists solutions named Sama Curate, Sama Annotate, Sama Validate, and Sama GenAI.

## What It Is

Sama is a managed data services provider and platform for AI training data. Teams engage Sama to label images, video, 3D point clouds (lidar and radar), and text, and to validate datasets and evaluate model performance. Outputs are annotated and validated datasets and model evaluation results aligned to a customer's model architecture and production goals.

## How the Workflow Runs

The site describes a three-step process. First, annotation strategy aligns scope, schedule, and delivery benchmarks with model goals. Second, detailed labeling guides keep annotation consistent across teams. Third, ongoing calibration adjusts labeling instructions as the data changes. Professional services are also offered for custom processes and production constraints.

## Service Areas

- Image annotation: object detection, localization, and segmentation.
- Video annotation: object tracking and temporal attributes.
- 3D point cloud annotation for lidar and radar data.
- Text annotation for generative AI: instruction following, preference ranking, and factuality.
- Data validation and model evaluation.

Industry pages cover ADAS and autonomous vehicles, banking and financial services, consumer and media, food and agriculture, generative AI, retail and e-commerce, and robotics and manufacturing.
