Hi, how should we do when we use AWS Bedrock for LLM & embeddings if LangChainLLMWrapper deprecated?

Wrappers are deprecated. Use factories instead:

bedrock_llm = llm_factory(
      provider="bedrock",
      model="anthropic.claude-3-sonnet-20240229-v1:0",
      region_name="us-east-1"
)

For embeddings,

bedrock_embeddings = embedding_factory(
      provider="bedrock",
      model="amazon.titan-embed-text-v1",
      region_name="us-east-1"
)

Thank you! I tried instructor_llm_factory but ValueError when using bedrock on the newest Ragas 🤔

Please open a separate issue for it. We can take a look there. :)
