Those aren't full prices though. You are aware of that, aren't you? Nor are the current "full API" prices necessarily truly enough to cover full costs. It is not unlikely that even those are far away from profitability. If they weren't, why all the financial gymnastics?

The real costs will only be known after the bubble bursts and the venture capital billions are going to dry up and the whole circular financing schemes are falling apart that are massively distorting numbers.

If the current subsidised rates are a good deal for you, nothing wrong with that. Just don't make decisions that are binding you to what is doomed to explode in prices in the foreseeable future. Also, if all that productive is going through the roof with AI, why is software generally getting worse and buggier. Are all those big tech companies getting suddenly more incompetent, just when they are all moving to processes that are heavily using LLMs?
