Hi and welcome to the Developer Forum!
Some people were earlier to the AI space than others and so were afforded access to personnel and features when demand was lower and the ratio of support personal to users was higher.
The reality is that no matter which supplier of AI services you go with, the demand now outstrips the supply of personal to help by a fair amount. This will get better with time as automation methods are developed and more staff are onboarded, for the moment it’s pretty much a waiting game and making sure you’re on as many lists as possible and take advantage of opportunities like conferences as and when they occur.
This is very much a case of the early bird catches the worm and no matter where you think you are in that list, you are before everyone who has yet to discover AI, so you are in fact ahead of the curve still by some margin.
