Sam Altman:

A lot of people want local inference, and somehow they assume that the problem is solved now because we have open-source models, we're going to be able to run them on our computers, and so we're not going to need all the stuff in the data center.

But from a global allocation perspective, actually it's quite terrible to have everybody, like, have a bunch of the world's limited supply of DRAM sitting in their own computer and being used five percent of the time.

Like you want maximum utilisation in the cloud if you're trying to deal with this very supply-constrained environment,

And somehow many people's intuition is the opposite of that
