SkyPilot as cloud orchestrator - Open-source, per-hour billing, 20+ cloud coverage

Fetched 2026-10-04. SkyPilot is an open-source cloud orchestrator that provides a unified interface to 20+ cloud providers. Key structural facts: (1) Open-source Apache 2.0 - the catalog data is freely available. (2) Catalogs refreshed every 7 hours via GitHub Actions for AWS, GCP, and Lambda. (3) Records both on-demand Price and SpotPrice for every instance type. (4) The catalog is a CSV file (vms.csv) with InstanceType, AcceleratorName, AcceleratorCount, vCPUs, MemoryGiB, Price, SpotPrice, Region, AvailabilityZone. (5) The GPU Compass portal (gpus.skypilot.co) renders this data as a user-facing comparison tool. (6) SkyPilot itself does not mark up prices - it passes through the cloud provider's rate. (7) The orchestrator handles the complexity of launching across different clouds with different APIs. SkyPilot is the most comprehensive and frequently-updated GPU price dataset publicly available, and its open-source nature means the data can be audited and verified.
