I use Requesty to get access to models from all providers, including Anthropic. It is pretty cheap and competitive with others for the quality. haiku 5.5 is one of the cheapest available, cheaper than Qwen while being superior in the price range (less than 10 cents per million tokens). I put 10 dollars to use on my hobby projects and I still have more than half after a couple of weeks. Using bigger models is dramatically more expensive, of course.
