Claude Haiku can do a LOT of the things you'd think you need GPT4 for. It's not as good at complex code and really tricky language use/abstractions, but it's very close for more superficial things, and you can call haiku like 60 times for each gpt4 call.
I bet you could do multiple prompt variations with haiku and then do answer combining to compete with GPT4-T/Opus at a fraction of the price.
Interesting! I just discovered that Anthropic indeed officially support commercial API access in (at least) some EU countries. They just don't support GUI access in all those countries:
