An incredibly fast, highly programmable serverless cloud platform designed explicitly for running complex Python and AI workloads.

About Modal

Modal fundamentally rethinks how developers deploy code to the cloud. Traditional cloud providers (like AWS) require developers to navigate a maze of Docker files, Kubernetes clusters, and complex provisioning dashboards just to run a heavy machine learning script. Modal allows developers to do this directly from their Python code.

A developer simply adds a `@modal.function` decorator above their standard Python function. When they run the script on their local laptop, the heavy lifting magically executes in the cloud in milliseconds. If a developer writes a function to transcribe an audio file using Whisper, Modal instantly spins up a massive cloud GPU, processes the audio, returns the text to the laptop, and shuts the GPU down.

The platform is revered by AI engineers for its blistering cold-start times. Unlike traditional serverless platforms that take seconds to wake up, Modal's highly optimized custom container engine spins up complex AI environments in a fraction of a second, making it the premier choice for deploying high-performance ML apps.

Frequently Asked Questions

Common questions and answers regarding Modal

Is Modal free to use?

The platform offers a highly generous free tier (often providing $30/month in credits) specifically designed to let developers build and prototype without friction.

Do I need to write Dockerfiles?

No, that is the core magic of Modal. You define your dependencies directly in the Python code, and the platform automatically builds the container environment in the background.

Can I host a web app on Modal?

Absolutely. Modal provides simple decorators to instantly expose your Python functions as standard webhooks, REST APIs, or interactive Gradio dashboards.

Does it support GPUs?

Yes, developers can explicitly request specific hardware (e.g., `gpu='A10G'`) directly in the code, and Modal will instantly provision that exact chip for the function.

Is it only for Python?

Currently, the platform and its incredible developer experience are heavily optimized and built exclusively for the Python ecosystem.
