Cloud infrastructure for teams that develop, train, and serve AI applications at scale.

Modal provides cloud infrastructure for AI teams that need to run inference, training, sandboxes, and serverless functions at scale. It is built for production workloads, with support for LLM, image, video, and audio inference, GPU-backed training, and isolated sandboxes for agents and untrusted code.
The platform includes OpenAI-compatible endpoints, autoscaling across CPU and GPU resources, and infrastructure for low-latency inference and async batch jobs. It also offers distributed storage for model weights and datasets, plus audit logs and enterprise-focused controls.
Pricing is billed by the second with no charge for idle time. The cheapest paid GPU rate listed is Nvidia T4 at $0.000164/sec, and CPU compute is also billed per second.
