SkyPilot is a framework for running LLMs, AI, and batch jobs on any cloud, offering maximum cost savings, highest GPU availability, and managed execution.

SkyPilot **abstracts away cloud infra burdens**:
- Launch jobs & clusters on any cloud
- Easy scale-out: queue and run many jobs, automatically managed
- Easy access to object stores (S3, GCS, R2)

SkyPilot **maximizes GPU availability for your jobs**:
* Provision in all zones/regions/clouds you have access to ([the _Sky_](https://arxiv.org/abs/2205.07147)), with automatic failover

SkyPilot **cuts your cloud costs**:
* [Managed Spot](https://skypilot.readthedocs.io/en/latest/examples/spot-jobs.html): 3-6x cost savings using spot VMs, with auto-recovery from preemptions
* [Optimizer](https://skypilot.readthedocs.io/en/latest/examples/auto-failover.html): 2x cost savings by auto-picking the cheapest VM/zone/region/cloud
* [Autostop](https://skypilot.readthedocs.io/en/latest/reference/auto-stop.html): hands-free cleanup of idle clusters

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

Install with pip:
```bash
pip install "skypilot[aws,gcp,azure,ibm,oci,scp,lambda,kubernetes]"  # choose your clouds
```
To get the latest features/updates, install [from source](https://skypilot.readthedocs.io/en/latest/getting-started/installation.html) or the nightly build:
```bash
pip install -U "skypilot-nightly[aws,gcp,azure,ibm,oci,scp,lambda,kubernetes]"  # choose your clouds
```

Current supported providers (AWS, Azure, GCP, Lambda Cloud, IBM, Samsung, OCI, Cloudflare, any Kubernetes cluster):

## Getting Started
You can find our documentation [here](https://skypilot.readthedocs.io/en/latest/).
- [Installation](https://skypilot.readthedocs.io/en/latest/getting-started/installation.html)
- [Quickstart](https://skypilot.readthedocs.io/en/latest/getting-started/quickstart.html)
- [CLI reference](https://skypilot.readthedocs.io/en/latest/reference/cli.html)

## 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**](https://skypilot.readthedocs.io/en/latest/reference/yaml-spec.html) (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`:

```yaml
resources:
  accelerators: V100:1  # 1x NVIDIA V100 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 torchvision

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

Launch with `sky launch` (note: [access to GPU instances](https://skypilot.readthedocs.io/en/latest/cloud-setup/quota.html) is needed for this example):
```bash
sky launch my_task.yaml
```

SkyPilot then performs the heavy-lifting for you, including:
1. Find the lowest priced VM instance type across different clouds
2. Provision the VM, with auto-failover if the cloud returned capacity errors
3. Sync the local `workdir` to the VM
4. Run the task's `setup` commands to prepare the VM for running the task
5. Run the task's `run` commands
