What is Modal?
Modal is a serverless platform designed for AI and data teams who need to run demanding compute jobs without the overhead of managing infrastructure. It allows you to execute any Python function in the cloud—from simple scripts to complex model training—with just a few lines of code. We handle the servers, containers, and GPU provisioning, so you can focus entirely on building and iterating on your applications.
Key Features
🚀 Instant, Scalable Compute Run your functions on hundreds of CPUs or GPUs in parallel, scaling up and down to zero in seconds. Our custom, Rust-based container stack enables sub-second cold starts, allowing you to iterate on cloud-based code with the speed of local development.
🐍 Infrastructure as Python Code Forget YAML and complex config files. With Modal, you define all your requirements—from the specific GPU model (like an H100) to Python package dependencies—directly within your Python script using simple decorators. This keeps your logic and infrastructure definitions in one place for ultimate clarity and control.
🧠 Optimized for AI & Data Workloads Modal is purpose-built for the demands of modern AI. Load gigabytes of model weights in seconds with our optimized container file system. Leverage built-in, persistent storage solutions like network volumes and key-value stores to manage datasets and state across your jobs effortlessly.
🌐 Deploy Web Endpoints with Ease Serve any function as a secure, auto-scaling HTTPS endpoint. Modal simplifies deploying ML models for inference, building APIs, or hosting interactive web apps, complete with support for custom domains, streaming, and WebSockets.
How Modal Solves Your Problems:
Modal is designed to tackle real-world engineering challenges. Here are a few practical applications:
Deploy a Scalable AI Inference Service You've developed a custom generative AI model and need to serve it via an API, but you anticipate unpredictable traffic. With Modal, you simply wrap your inference code in a function, specify the required GPU, and deploy it as a web endpoint. Modal automatically scales your containers from zero to handle sudden traffic spikes and scales back down just as fast, so you only pay for the compute you actually use.
Accelerate Model Training and Fine-Tuning A researcher needs to run dozens of fine-tuning experiments on a large dataset. Instead of waiting for a shared GPU cluster or manually managing multiple VMs, they use Modal to launch all experiments in parallel, each with its own dedicated A100 GPU. This massively parallel approach turns a multi-day process into a task that completes in hours, dramatically shortening the research and development cycle.
Execute Large-Scale Batch Processing An analyst needs to process terabytes of data stored in a cloud bucket. Using Modal's simple fan-out parallelism, they write a Python function to process a single file and apply it across thousands of files simultaneously. This leverages massive amounts of CPU and memory on-demand, transforming a job that would take days on a single machine into one that finishes in minutes.
Unique Advantages
Unmatched Developer Velocity: The combination of sub-second container starts and zero-config deployment means you can test and deploy in the cloud as quickly as you can on your laptop. This eliminates the frustrating delays common with traditional serverless platforms and complex CI/CD pipelines, allowing you to ship faster.
True Serverless Economics for Heavy Compute: Modal applies a strict pay-for-what-you-use model, billed by the second. This principle extends to high-end GPUs, allowing you to access state-of-the-art hardware without the prohibitive cost of keeping it idle. When your code isn't running, you pay nothing.
Conclusion:
Modal removes the friction between your code and the cloud. It provides the power of a supercomputer with the simplicity of a Python library, empowering you to build and scale ambitious AI and data applications faster and more efficiently than ever before.
