About Scale AI

What Is Scale AI

Scale AI is a data infrastructure company. It supplies the labeled training data, human feedback, and evaluation tooling that go into building large AI models, and it also builds full systems for organizations that want to deploy AI in sensitive work.

Most language and vision models you use today were trained on data that someone had to sort, tag, and rate by hand. Scale AI does that work at scale, either with its own contributor network or with the processes it sells as a platform. Its Scale Data Engine covers image, video, text, audio, and LiDAR labeling, along with the human preference ranking that makes models more useful.

The company has widened its scope well beyond labeling. It now runs expert level model evaluations, red teaming, and a no-code agent platform called Donovan for public sector and defense work. Two limits matter before you reach out. There's no free plan and no self serve signup, so it's built for organizations with a real data budget. Pricing isn't published either. You start with a demo and get a quote.

Getting Started

  1. Go to scale.com and request a demo through the contact form for your use case, whether that's Generative AI, enterprise, healthcare, or national security.
  2. Talk through your data and model goals with the sales team. You'll define what needs labeling or evaluating and agree on scope.
  3. Get access to the Scale platform. Teams upload data, set task instructions, and configure quality controls for their project.
  4. Send work through the pipeline. Contributors label, review, and rate the data, and you track progress and accuracy as results come back.
  5. Pull the finished dataset or evaluation report and feed it into your model training or release process.

Key features

Multi-Modal Data Labeling and Annotation

Scale AI acts as a managed data annotation service for image, video, text, audio, document, and LiDAR data in one platform. You upload raw data, set the task, and get labeled output built for training or fine-tuning models. The mix of annotation types matters because most real projects need more than one, and running them through separate vendors is where quality and timelines slip.

Generative AI Data Engine

For generative models, the Scale Data Engine produces complex prompt and response pairs, applies human preferences to model outputs, and runs prompt injection tests to find vulnerabilities. That covers the work after pre-training, where a model's usefulness and safety get shaped, which is the part many teams underestimate.

RLHF and Human Preference Data

Reinforcement learning from human feedback depends on people ranking model answers, and Scale AI runs that ranking at scale through its contributor network. The company says it has paid over $1 billion to contributors and collected billions of human decisions. The result is the preference signal that steers a model toward answers users actually want.

Model Evaluation and Red Teaming

Scale AI measures how well models perform, benchmarks them against expert level tasks, and tests them for safety and alignment problems. Evaluation is separate from training, and teams use it to decide whether a model is ready to ship. For anyone releasing a model, this is the evidence that backs the launch.

Scale Donovan for Public Sector Agents

Donovan is a no-code platform for building, testing, and deploying AI agents on mission specific workflows. It runs on classified and air gapped networks and is available on DISA IL4 and FedRAMP High authorized cloud. The point for agencies is deployment where commercial tools usually can't go.

Data Governance and Quality Controls

Projects carry review steps, quality checks, and a record of who labeled what. This matters in regulated fields where someone has to show how a dataset was built and why it's trustworthy. Scale AI sells that traceability as part of the platform rather than leaving it to the customer.

API and Platform Integration

Scale AI exposes a documented API so teams can programmatically create tasks, upload data, and pull results into their own pipeline. That means labeling and evaluation can run as part of an existing ML workflow instead of through manual uploads. For engineering teams, it's the difference between a service you call and a service you babysit.

Pros and cons

Pros

  • Covers a wide range of data labeling types in one platform, from images and video to text, audio, and LiDAR
  • Human feedback and RLHF data help models learn which answers people actually prefer
  • Separate evaluation and red teaming services support model release decisions with evidence
  • Donovan brings agent deployment to classified and air gapped government networks
  • A documented API lets teams plug labeling and evaluation into their own ML pipeline

Cons

  • No free plan and no self-serve signup, so it's out of reach for individuals and small teams testing an idea
  • Pricing isn't published, which means a demo and sales cycle before you know what anything costs
  • The public sector focus of Donovan won't help commercial teams that just want a general purpose assistant
  • Running labeling through an outside vendor means data leaves your environment, which some regulated teams can't accept
