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-source database of AI models, prices and capabilities
Every model uses a consistent provider/model format so the same model across providers can be compared directly.
Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
Input and output prices per million tokens listed alongside release and update dates.
Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.


SpecialistRelies heavily on managed human-in-the-loop workforce services for data validation, offering less self-serve technical tooling than Labelbox.
#2Delivers enterprise-grade labeling and model evaluation at massive scale, but often requires higher enterprise budgets than Labelbox.

Offers robust multimodal annotation and workflow automation, featuring slightly more intuitive data curation pipelines for computer vision teams.

SpecialistTrack, evaluate, and ship AI models and agents in one connected environment.

Specializes in advanced computer vision and physical AI data pipelines, though with a narrower focus than general text-and-image labeling.

SpecialistIncludes model pricing trackers and developer news alongside tools directories, but less focused on raw API specs.

Free / Open-sourceProvides a flexible open-source alternative for custom data labeling, but requires self-hosting and manual infrastructure maintenance.


SpecialistFocuses strictly on LLM evaluation, testing, and observability rather than raw data annotation and training dataset curation.

SpecialistCatalogues and compares AI infrastructure tools and services across categories, but lacks deep per-token pricing tables.

Provides efficient smart annotation tools and managed labeling services, but has a smaller ecosystem for complex enterprise agent workflows.

SpecialistArchives how various AI models answer identical prompts over time, offering qualitative comparison rather than pricing.
