So a big concern then? (Although not a death sentence)
Even today, Azure and AWS are not really cheaper or better - for most situations, they're more expensive, and less flexible than what can be done with OS infrastructure. For companies who are successful making software, Azure is more of a kneecap and a regret. Many switch away from cloud, despite that process being deliberately painful - a shocking mirror of how it was switching away from Microsoft infrastructure of the past.
Shouldn't something like Kubernetes or Android's flavor of open source be on the radar? Seems like there are plenty of large players that might turn their 4th place closed source API into a first place open ecosystem.
Distillation for specialisation can also raise the capacity of the local models if we need it for specific things.
So its chugging along nicely.
