The environments frontier AI trains on, and the agents that do the recurring work
Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.
On-device pose estimation for fitness, rehab and workout apps
17 COCO keypoints stream directly on the phone or in the browser with no API key and no video upload.
An optional API key returns repetition counts, joint angles and a movement form score for exercises like squats and push-ups.
One engine with three integration paths: native React Native (Expo Go), browser JavaScript, and a WebView or iframe embed.
Ready-made back flexibility test, flexibility analysis with automatic angle detection, and pose comparison against a reference position.
