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.
Document API changes automatically and ship accurate release notes
Register your API environments and the platform monitors them for changes, so nothing is missed between releases.
Output follows the OpenRelease standard, giving every release a consistent, reviewable structure instead of an ad-hoc bullet list.
Publish as HTML or email, or export structured JSON, YAML and PDF on higher tiers for downstream tooling.
Push notes to Slack, Dropbox, S3 or a wiki, or send them by email, reaching engineers, PMs and customers from one source.
SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.
