AWS Bedrock Approach vs. Google & OpenAI

Are the Giants taking the same approach?

AWS Bedrock is the latest GenAI offering on AWS. A successor of its private beta launched in April, Bedrock opens doors to using foundation models (FMs) of leading AI corporations through a single API. Sparing developers the headache of deploying and managing those models themselves.

But it also comes months after Google and OpenAI released their offering. How does it compare? Which one should I choose? And is there a difference at all?
