This sounds like an issue where the hyperscalers are acknowledging that the new Foundation model firms may in fact be worth more than they are. Anthropic looks increasingly likely to exceed AWS revenue next year, and OpenAI will likely do the same with Azure.
3 years ago a Foundation model seemed like a feature of a hyper scaler, now hyper scalers look like part of the supply chain.
I think both got taken by surprise. Last year the talk was that AI was a bubble, demand was soft, pilots projects were failing, etc. Model providers still believed, but thought they had a long ramp up period to build out their own datacenters. Then in late Autumn/Winter, something happened. Model capability reached a threshold and demand exploded, then just kept exploding. Model firms are scrambling to find any compute capacity they can, which means striking any deals problem with hyper scalers. So question is whether model providers can get enough compute without having to effectively sell themselves to hyper scalers.
