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.
Search millions of AI prompts and generate images and videos with every major model
Search and filter a large library of community prompts by model, style or category, and see the exact text behind each result.
Create images and videos on-site with models including ChatGPT Image, Midjourney, FLUX, Nano Banana, Seedream, Veo and Sora.
Browse documented AI image, video and language models in one catalogue to decide which engine fits your task.
Paid plans keep your output unlisted, and unused generation credits accumulate instead of expiring each month.

SpecialistA massive Japanese community platform specializing in AI illustration discovery, sharing, and prompt generation.
#1Free / Open-sourceProvides deep community-driven model and prompt discovery for image generation, with built-in cloud execution capabilities.
Combines prompt discovery and model hosting with online generation for Stable Diffusion and LoRA checkpoints.
Features a massive community prompt library with instant chat execution, though with less curated image-specific search filters.
Free / Open-sourceOffers trending prompt discovery paired with an integrated generation canvas for direct image remixing.
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.
Delivers enterprise-grade labeling and model evaluation at massive scale, but often requires higher enterprise budgets than Labelbox.

An online marketplace for buying and selling verified prompt templates, whereas PromptHero focuses on free community discovery.

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.
