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.

Really interesting direction. What do you see as the first real use case for CGI — cloud procurement, compute financing, or eventually something closer to a tradable benchmark?

@tizaolai886 eventually it will be a bit of everything you mentioned. the first use case is now cash settled derivatives, basically hedges on gpu prices, using CGI as a reference rate.

@raysong cool.. combining with finance is such a bold idea :)

Using a weighted median instead of a simple average seems like an important design choice. I’d be interested to understand how the weights are calculated and how you prevent one large provider—or several unusually low listings—from having too much influence on the final number.

@matthewwei so, we actually are using a interquantile mean instead of median. this means, any outlier would not have an impact on the price. the weights take in consideration of how lively a data source is. you can read more about it in our methodology!

Nice, this is genuinely useful. GPU pricing has been a black box for so long, having an open-source benchmark like this makes it way easier! Are you planning to pull prices from just the big cloud providers, or also smaller GPU rental platforms to keep the index honest?
Really solid writeup on the methodology, it's rare to see this much transparency.
How often do the liveness weights actually shift in practice, or is it fairly stable from week to week once things settle?
Finally, a GPU price index that doesn't make me feel like I'm deciphering ancient runes.
Already sent this to my team, we've been manually tracking cloud costs in a spreadsheet like cavemen.
Any chance you'll add Lambda Labs or Vast.ai to the provider list?
One trustworthy reference for something this opaque feels overdue to me, and being able to check how it's put together is what would make me actually believe it.

Congrats on shipping this @raysong
The interquantile mean approach is smart, trims the outlier providers without throwing away real signal like a plain median would.
Just curious if spot pricing is on the roadmap, or is CGI staying on demand only for now? Following this one for sure
