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.

Open AI research for everyone — datasets, models and tools, free for all
Re-LAION-5B offers about 5.5 billion image–text link pairs, and LAION-BVD adds a 10-million-hour open video corpus for vision-language, audio-language and video research.
Scalable, openly licensed implementations plus pretrained weights for contrastive language–image training, so teams can reproduce or fine-tune CLIP-style models themselves.
Training code, evaluation utilities, papers and documentation are released alongside results, letting researchers compare datasets and checkpoints on equal footing.
Open-sci-ref publishes open baselines and intermediate checkpoints for comparing training datasets and language-model quality.

SpecialistRelies heavily on managed human-in-the-loop workforce services for data validation, offering less self-serve technical tooling than Labelbox.
Delivers enterprise-grade labeling and model evaluation at massive scale, but often requires higher enterprise budgets than Labelbox.
