With Windsurf I'm able to pick any of the premium language models. I.e. Claude 3.7 Sonnet costs 1 credit / prompt, whereas the thinking model costs 1.25 credits, and o3 costs a whopping 7.5 credits.

It's simply passing on the cost of respective model's costs, I think. I can image it's hard to come up with an affordable / interesting flat rate _and_ support all those differently priced models.
