It supports fast prototyping, serverless APIs, scheduled jobs, > GPU inference, distributed volumes, and sandboxes. Important notes: - Modal's primitives are embedded in Python and tailored for AI/GPU use cases, but they can be used for general-purpose cloud compute. - Modal is a serverless platform, meaning you are only billed for resources used and can spin up containers on demand in seconds. You can sign up for free at [https://modal.com] and get $30/month of credits. ## Guide - [Introduction](https://modal.com/docs/guide) - Custom container images - [Defining Images](https://modal.com/docs/guide/images.md) -
