Sama - 2026 Pricing, Features, Reviews & Alternatives

Sama is a cloud-based, full-cycle data annotation, validation, and evaluation service that delivers human-verified training data for enterprise AI and machine learning teams. The platform supports a broad range of data modalities, including image, video, text, audio, lidar, and sensor fusion, and provides configurable annotation workflows suited to industries such as autonomous vehicles, robotics, retail, healthcare, and natural language processing. Annotation tasks are executed by a managed workforce operating within an ISO-certified quality management system, with multi-stage quality assurance built into every project pipeline.

The service combines a SaaS annotation platform with managed workforce operations, giving enterprise teams access to scalable labeling capacity without the overhead of building in-house annotation infrastructure. Quality is enforced through SamaAssure, a structured QA framework that applies validation checkpoints and acceptance criteria across annotation batches. Sama also offers model evaluation services, allowing teams to assess model performance against human-verified ground truth data. Workforce operations are structured to meet ethical sourcing standards, with annotators employed under fair wage and working condition policies, which is increasingly relevant for enterprises with responsible AI procurement requirements.
