Hey @viveksilimkhan1, thanks for your PR! We'll give some feedback shortly, looks great at first glance. Quick question - is |

Hi @rmitsch, as far as I know, boto3 is the recommended way for using Bedrock services in python, and since boto3 is maintained by AWS, any updates in the API in future would require minimal changes. I am not sure how this can be implemented with native REST libraries. |

For consistency we'd like all of the REST models to inherit from the REST class. Could you modify your Bedrock class to do so? You can have a look at any of the other REST-based model classes in spacy_llm/models/rest for inspiration (particularly the azure directory in particular, as it's a rather similar situation).

Yes, sure @rmitsch, will do it.

I guess it's ok to expect boto3 when using Bedrock models. It seems to be tedious to work around it otherwise.

There is no error processing here. Could you add some safeguards for common errors? Auth errors etc.

I think Titan Express and Titan Lite are quite similar in their usage, so let's merge this to one registry entry.
