Open-source Python framework for real-life ML, AI, and data science workflows
Flow and step decorators turn ordinary Python functions into versioned, resumable pipelines without YAML or DSL boilerplate.
Move the same flow from a laptop to Kubernetes, AWS Batch, Azure, or GCP and run steps on GPUs, many cores, or large memory pools.
Metaflow stores variables and artifacts from every step so you can compare experiments, debug past runs, and reproduce results later.
Point a flow at your production scheduler and let it react to incoming data or events instead of manual re-runs.
Serverless cloud infrastructure for AI and data workloads
Write plain Python, attach GPUs or containers, and deploy HTTPS endpoints that autoscale with traffic and scale to zero when idle.
Launch isolated, secure environments for coding agents, RL rollouts, and untrusted code, with sub-second starts and support for over a million concurrent sandboxes.
Run fine-tunes, LoRA, full training, and reinforcement learning on elastic single or multi-node GPU capacity with no quota requests.
Serve LLMs and image, video, or audio models through OpenAI-compatible endpoints, or bring your own inference stack and let Modal handle the infrastructure.
