Bedrock uses the Converse API (langchain-aws) and the AWS credential chain, so it has its own client like Anthropic/Google rather than the OpenAI-compatible registry. langchain-aws is an optional dependency (pip install ".[bedrock]"), lazy-imported with a clear install hint; importing the package never requires it. The model name is a Bedrock model ID / inference profile ID.
