I’m happy to see this PR and the progress the pydantic-ai team has made. Good work on this!

As a small personal request (my little selfish wish), could you please add me as a co-author to this PR?

I'm going to have to rework this a bit. I'll continue my work tomorrow.

Does AWS Bedrock supports using the OpenAI API natively, or do we need to use the Converse API?

Bedrock does not support openai api, there is a project to proxy converse api to openai api: https://github.com/aws-samples/bedrock-access-gateway

For anthropics' models, we can use AsyncAnthropicBedrock, but if we want to use aws's models(e.g. nova) or llama model on bedrock, Converse API is the next generation standard to replace Invoke API with LLMs.

Right, so this PR is still needed. 👍

Thanks.

Pipeline passing. I'll do my usual self review.

We still need to add the other inputs i.e. ImageUrl, and BinaryContent, but I'll merge without supporting it.

Thanks @Wh1isper 🙏
