A serverless runtime for AI workloads that gives Python developers autoscaling GPU containers, background tasks, and sandboxes without infrastructure work.
Beta9 is the open source runtime for serverless AI workloads that powers Beam, the fully managed platform built on top of it. It presents a Pythonic interface for deploying and scaling AI applications, so the container image, the autoscaler, and the retry policy become decorator arguments rather than infrastructure you maintain on the side.
A custom container runtime, scheduler, and embedded caching bring containers up in under a second. An endpoint decorator publishes an autoscaling inference endpoint with a chosen GPU, CPU and memory allocation, a task queue decorator turns a function into a resilient background job that can replace a Celery queue, and a Sandbox class spins up an isolated container for running code an LLM generated.
The runtime covers the parts of a deployment you would otherwise assemble yourself.
- Fast cold starts: containers launch in under a second on the purpose-built runtime and scheduler.
- Parallelization: a single workload fans out across hundreds of containers.
- Scale to zero: workloads are serverless by default rather than always on.
- Developer experience: hot reloading, webhooks, and scheduled jobs come with the runtime.
- Volume storage: distributed storage volumes mount into running containers.
- GPU support: run on Beam's cloud with 4090s, H100s and others, or bring your own GPUs.
Installation is a pip install of the client package, followed by a getting started guide for the first deployment. Beta9 can be self-hosted for free or run as managed cloud hosting through Beam, and the code is AGPL licensed.
