their subscriptions aren’t subsidised. in fact its near 100% margin. you are getting the lowest priority access with no service level guarantee in the gaps in supply left over by api users, anthropic’s cost basis on hardware would be the same without subscriptions.
I don't know about near 100% margin, but definitely true on lowest priority access. Plenty of times I get model overloaded, outages, etc on my consumer subs, then switch to my work API sub and everything is perfectly fine.
