Computable GPU Index (CGI) is an open‑source tool that calculates a USD price per GPU‑hour by aggregating published on‑demand rates from a fixed panel of cloud providers. Its methodology is mathematically robust and fully reproducible.
Because CGI is open‑source, you can download the code, run the same calculations, and compare the output to the published rates on each provider’s website. Any discrepancy can be investigated and corrected.
CGI is ideal for quick, transparent cost comparisons, but it focuses on on‑demand rates. Enterprises that rely on reserved instances, spot pricing, or complex discount structures may need additional tools for full budgeting.
