Just because the hardware and inference costs may decrease in the future doesn't mean prices will. The AI vendor market is the furthest thing from a competitive industry where there are limited barriers to entry and new market entrants exert downward pressure on prices and profit margins.
Every single company in this market is losing billions on this business, and the only way to make it back is to acquire paying customers at a loss and jack up prices later.
Since Guardian Angel is an inference vendor [1] hopefully they will set sustainable prices from day one so they don't need to increase prices later.
