Node-based visual AI studio for images, video, 3D and audio
Connect models, samplers, conditioning, LoRAs and output nodes on an infinite canvas where every step is visible and adjustable.
One interface for image generation, video, 3D assets and audio or music workflows, with support for leading open and partner models.
Run ComfyUI locally on your own GPU, or open the same workflows in the cloud when you don't have the hardware.
Deploy any workflow as a production API so your own app or agent can generate outputs on demand.

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.
SpecialistServes as a massive community hub for discovering open-source models, replacing ComfyUI's manual model downloading workflow.

Provides cloud-hosted ComfyUI execution and APIs, sparing you from managing local GPU hardware constraints.

SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.
#3
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.

SpecialistFocuses on custom game asset training and node workflows, but lacks ComfyUI's infinite open-source node flexibility.

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.
Delivers dedicated cloud instances pre-configured for ComfyUI and Stable Diffusion, replacing local workstation setups.

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.
