FAQ

FAQs about CVAT on OpenTrain

Short answers on hiring and running projects with CVAT.

How do I add hired Data Labelers to my CVAT workspace?

After you hire someone on OpenTrain, invite them to your CVAT workspace using your standard user management settings. Whether you're self-hosting or using CVAT's cloud platform, you control access and permissions. OpenTrain handles recruiting, communication, and payments.

Does OpenTrain access or store my annotation data?

No. Your data stays in your CVAT instance. OpenTrain is a hiring and payment platform, not an annotation tool. We never see, access, or store your images, videos, or labels.

How are Data Labelers vetted for computer vision work?

Our AI screens resumes, runs interviews, and evaluates candidates before they can apply to jobs. For CVAT projects, we look for experience with annotation types like bounding boxes, polygons, segmentation, and video tracking, plus the ability to follow labeling guidelines consistently.

How much does OpenTrain cost?

You set the rate you pay your Data Labelers. OpenTrain charges a platform fee on top of that. No subscriptions or minimums. See our pricing page for details.

Can I start with a small pilot before scaling?

Yes. Most teams post a small job, hire one or two Data Labelers, and scale up once they're confident in the quality. It's the best way to test fit before committing to a larger project.

What is Managed Service, and when should I use it?

Managed Service is for teams that need end-to-end support. We recruit, onboard, train, and manage a dedicated team for your CVAT projects. It's a good fit if you're scaling quickly, running complex annotation workflows, or don't have time to manage a distributed team yourself.
