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.
Run and scale durable AI agents on your own infrastructure
Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
SpecialistExtremely fast serverless execution optimized specifically for generative media models rather than general Python code.
Provides 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.
#3Rent 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
Free / Open-sourceThe TypeScript framework for building, deploying, and observing AI agents
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.
