Modal
Modal is a serverless cloud platform for AI and data workloads. Modal lets developers write ordinary Python and run it on remote GPUs and CPUs with sub-second cold starts, instant autoscaling, and declarative container images. The platform's primitives — Functions, Sandboxes, Volumes, Images, Secrets, Dicts, Queues, Schedules, and Web Endpoints — cover inference, fine-tuning, multi-node training, batch processing, agent code execution, and HTTP/web APIs. Modal sells per-second metered compute across the full NVIDIA GPU lineup (T4 → B200) under Starter, Team, and Enterprise plans. Modal Labs raised a $355M Series C in 2026 and is used in production by Decagon, Runway, Physical Intelligence, Suno, Chai Discovery, Lovable, Quora, Reducto, and many others.
Modal publishes 17 APIs on the APIs.io network, including Apps API, Dicts API, Environments API, and 14 more. Tagged areas include Serverless, GPU, Cloud Compute, AI Infrastructure, and Sandboxes.
The Modal catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Modal’s developer surface includes authentication, developer portal, documentation, getting-started guide, code examples, engineering blog, changelog, and 51 more developer resources.
