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.
Curate, annotate and QA multimodal training data in one governed workspace
Annotate image, video, audio, text, documents, medical imaging, pathology, geospatial, sensor and tabular data in one governed workspace rather than stitching together separate tools.
Bring your own models into the labeling loop for pre-annotation, segmentation and object tracking, with multiple model stages combined with human review before anything is approved.
Consensus, Quality Gate and expert review stages validate labels against hidden answer keys to keep training data reliable — Unitlab cites 99%+ QA-backed accuracy.
Build dataset versions as data evolves, assign tasks, track changes and keep annotation history and label lineage auditable across the AI lifecycle.
SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.
Free / Open-sourceReal-time vision AI models and a full platform to train, annotate, and deploy them
Human-validated training data and evaluation services for frontier AI models
Delivers enterprise-grade labeling and model evaluation at massive scale, but often requires higher enterprise budgets than Labelbox.
AI data infrastructure for building production-grade models
SpecialistTrack, evaluate, and ship AI models and agents in one connected environment.
The multimodal data layer for computer vision and physical AI teams
SpecialistEnterprise AI training data, annotation and evaluation services
Free / Open-sourceLabel any data. Evaluate any AI.
Free / Open-sourceFind where your physical AI models fail, then fix the data.
SpecialistFocuses strictly on LLM evaluation, testing, and observability rather than raw data annotation and training dataset curation.
