OpenAI is locked into _someone's_ compute resources... the one that is the cheapest. AFAIK OpenAI doesn't have much (any?) of their own hardware. With the mega-clouds buying up all the GPUs and building datacentres, you have to 'partner' with someone. Most likely the one that gives you the biggest discounts. The amount of compute that OpenAI needs dwarfs almost any other consideration.
