Computable

Computable publishes the Computable GPU Index, an open source reference price for GPU compute. The index is a US dollar price per GPU hour computed from the published on demand rental rates of a fixed panel of providers, and it exists because every provider quotes a different number and the existing indexes are closed. Every data point is sourced, timestamped and kept, and anyone can clone the repository and recompute a print to get the same figure the company published. It is for people who trade, rent or finance compute and need a neutral benchmark: cloud buyers negotiating rates, providers pricing inventory, and financiers underwriting GPU backed deals. The index currently tracks the H100, H200, B200 and B300, updating every 15 minutes, with charts and history on the market site. The methodology uses an interquantile mean so that outer third votes have little influence, which makes the number resistant to outliers and to manipulation by any single source. Live values can also be pulled into any MCP client through the company's MCP endpoint, which is anonymous, read only and needs no API key, so agents and internal tools can query the current rate directly. The index is free to access and no pricing is published for any other service. The company is backed by Y Combinator and founded by people from Jump Trading and Coinbase, and it invites anyone who trades, rents or finances compute to say what they want from a reference rate.
