SkyPilot is an open-source framework for running AI and batch workloads on any infra.

SkyPilot is easy to use for AI users:

Quickly spin up compute on your own infra
Environment and job as code — simple and portable
Easy job management: queue, run, and auto-recover many jobs

SkyPilot unifies multiple clusters, clouds, and hardware:

One interface to use reserved GPUs, Kubernetes clusters, or 16+ clouds
Flexible provisioning of GPUs, TPUs, CPUs, with auto-retry
Team deployment and resource sharing

SkyPilot cuts your cloud costs & maximizes GPU availability:

Autostop: automatic cleanup of idle resources
Spot instance support: 3-6x cost savings, with preemption auto-recovery
Intelligent scheduling: automatically run on the cheapest & most available infra

SkyPilot supports your existing GPU, TPU, and CPU workloads, with no code changes.

Getting started

SkyPilot in 1 minute

A SkyPilot task specifies: resource requirements, data to be synced, setup commands, and the task commands.

Once written in this unified interface (YAML or Python API), the task can be launched on any available cloud. This avoids vendor lock-in, and allows easily moving jobs to a different provider.

Paste the following into a file my_task.yaml:

resources:
  accelerators: A100:8  # 8x NVIDIA A100 GPU

num_nodes: 1  # Number of VMs to launch

# Working directory (optional) containing the project codebase.
# Its contents are synced to ~/sky_workdir/ on the cluster.
workdir: ~/torch_examples

# Commands to be run before executing the job.
# Typical use: pip install -r requirements.txt, git clone, etc.
setup: |
  pip install "torch<2.2" torchvision --index-url https://download.pytorch.org/whl/cu121

# Commands to run as a job.
# Typical use: launch the main program.
run: |
  cd mnist
  python main.py --epochs 1

Prepare the workdir by cloning:

`1`	`git clone https://github.com/pytorch/examples.git ~/torch_examples`

Launch with sky launch (note: access to GPU instances is needed for this example):

`1`	`sky launch my_task.yaml`

SkyPilot then performs the heavy-lifting for you, including:

Find the lowest priced VM instance type across different clouds
Provision the VM, with auto-failover if the cloud returned capacity errors
Sync the local workdir to the VM
Run the task’s setup commands to prepare the VM for running the task
Run the task’s run commands

See Quickstart to get started with SkyPilot.
