> Deepseek has some models in Bedrock.

Just looked into it, seems like at most they have just 3.2, not 4: https://aws.amazon.com/bedrock/pricing/

Looking around their catalogue more, most of their models seem quite outdated, aside from the OpenAI and Anthropic ones (but those get more expensive). I wouldn't willingly pick Bedrock and would instead throw money at OpenRouter, that has both a bunch of providers, as well as almost any model for you to try.
