Its a google model. The edge cases are crazy to deal with and have taken a long time to find. I am also finding that since it has no fallbacks but no published rate limit I am single handedly taking the model down on what I thought were a reasonable amount of request. There is no other fallback that isn't google. I'm worried that with sustained usage from my users on launch in a few days. Clearly google can't be making that much money on it it im like 10% of the usage and the top 2-3 user of it spending several hundred a month in pre launch testing.
So why would they care to help a small time start up? I will have to jump to a cost effective different model and find the footguns all over again at somepoint.
Not sure where im going with this but just wanted to let others know </rant>
