Corporate AI will likely go on prem where costs can be fixed.

I would imagine this is the route it will go too, once (if) hardware supply chains catch up and costs can start coming down.

It's too useful to ignore, but too expensive to pay-as-you-go at current pricing for frontier models. Smaller, less capitalized companies will use the subscriptions (if they still exist by then), and larger firms will just build out their own compute for their dev teams.
