AI data labeling and model evaluation

Scale AI is the leading data labeling and AI data infrastructure platform used by major technology companies, government agencies, and enterprises to build and improve AI systems. The platform provides high-quality human-in-the-loop data annotation across images, video, text, 3D point clouds, and maps, along with generative AI tools and evaluation capabilities.

Key Capabilities

Scale AI offers the Data Engine for collecting, labeling, managing, and evaluating data for AI projects, supporting image annotation, semantic segmentation, LIDAR/RADAR annotation, and text labeling. Two annotation options are available: Scale Rapid with their managed workforce for turnkey labeling, and Scale Studio where teams bring their own annotators to work on the platform. The Generative AI platform provides model evaluation, RLHF data, and fine-tuning data. Scale also offers pre-built datasets and data curation tools for training foundation models.

Who Should Use Scale AI

Scale AI is designed for large enterprises, autonomous vehicle companies, government agencies, and AI research labs that need high-quality labeled data at scale. It is best suited for organizations with significant data labeling needs and budgets, particularly those working on mission-critical AI applications where data quality directly impacts model performance.

Getting Started

Visit scale.com and use the self-serve option for experimental or research projects with pay-as-you-go pricing and initial free credits. For enterprise needs, book a demo through the sales team to discuss custom pricing and deployment options. The onboarding process for enterprise customers includes dedicated support and custom workflow configuration.

Pricing & Accessibility: Scale AI uses custom enterprise pricing with costs varying by task type, volume, and platform choice (Rapid vs. Studio). A limited self-serve plan is available for experimental projects with pay-as-you-go pricing and some free credits (first 1,000 labeling units). Enterprise contracts require consultation with their sales team.

Why Consider Scale AI: Scale AI is the industry standard for high-quality data labeling at enterprise scale, trusted by leading AI companies and government agencies for mission-critical applications where data quality is paramount to model performance and safety.

Frequently Asked Questions about Scale AI

How much does Scale AI cost?
Scale AI does not publicly list pricing. Costs vary by task type, data volume, and platform choice. A limited self-serve plan offers pay-as-you-go pricing with initial free credits for the first 1,000 labeling units. Enterprise contracts require booking a demo and going through a sales process.
What types of data can Scale AI label?
Scale AI supports annotation across images, video, text, 3D point clouds, LIDAR/RADAR data, maps, and documents. This includes tasks like bounding boxes, semantic segmentation, polygon annotation, text classification, and named entity recognition.
What is the difference between Scale Rapid and Scale Studio?
Scale Rapid uses Scale's managed workforce to handle annotation end-to-end, providing turnkey labeling. Scale Studio lets you bring your own annotation specialists to work on Scale's platform, giving you more control over the labeling process while leveraging Scale's tools and quality management.
