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.
Serverless cloud infrastructure for AI and data workloads
Write plain Python, attach GPUs or containers, and deploy HTTPS endpoints that autoscale with traffic and scale to zero when idle.
Launch isolated, secure environments for coding agents, RL rollouts, and untrusted code, with sub-second starts and support for over a million concurrent sandboxes.
Run fine-tunes, LoRA, full training, and reinforcement learning on elastic single or multi-node GPU capacity with no quota requests.
Serve LLMs and image, video, or audio models through OpenAI-compatible endpoints, or bring your own inference stack and let Modal handle the infrastructure.

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


SpecialistExtremely fast serverless execution optimized specifically for generative media models rather than general Python code.
#3Provides flexible GPU infrastructure and serverless endpoints, though less focused on pure Python function decorators.

SpecialistFocuses heavily on managed open-source model inference APIs rather than arbitrary custom container execution.
Rent cloud GPUs by the second from a global marketplace
Delivers robust enterprise GPU clusters and managed inference, requiring more infrastructure setup than Modal's serverless approach.

Easier model packaging via Cog, but offers less arbitrary serverless Python container execution than Modal.

SpecialistLow-cost serverless inference APIs for 200+ open models

SpecialistFocuses on custom game asset training and node workflows, but lacks ComfyUI's infinite open-source node flexibility.
Provides integrated development studios and training workflows, but with less granular serverless function orchestration.
SpecialistCombines ready-to-use model APIs and serverless GPU jobs, with simpler API consumption than custom Modal apps.
