Computable GPU Index (CGI) is a USD price per GPU-hour, computed from the published on-demand rental rates of a fixed panel of providers. The methodology is mathematically robust, and anyone can verify and reproduce every print.

Can contributors reproduce the published values on a standard laptop?
@inith271 yes! the arithmetics are light plus some small regressions.
Congrats @raysong What's been the hardest part of getting all 28 providers to agree on data quality and consistency? I'd imagine some are way messier to work with than others.
@croft_benjamin we have a very neat methodology that aggregates the data and scores providers based on the liveness of their data. feel free to check it out!
Why use a weighted median instead of a simple average?
@kisekiya to be clear, we are using a interquantile mean which is the weighted mean of the central third of the voting mass. the reason why this is better than a simple average is it makes the index resistant to outliers.
Awesome to see confirmability built in from day one instead of bolted on later. what actually triggered the idea, did you run into this exact pricing problem directly while working on Computable?
Publishing the methodology makes the index easier to trust.
@sylvialane exactly!
Are historical observations available for download and independent analysis?
@jin_shang1 they will be available soon. you could also run the code and produce the prints alongside us.
Very relevant as GPU pricing becomes harder to compare.
@wys1010hope it helps!
