RAG Embedding LLM + MetaGPT

[Terry-cyx]

I'm going to do a work which need LLM to read PDF. I found it's easy to do in LangChain with RecursiveCharacterTextSplitter and embeddings. But in MetaGPT, it seems hard to do.
I found embedding in config2.yaml, but do not know how to use it.
I'm using zhipuai, and the ZhipuAIEmbeddings, ZhipuAILLM are customized.
Here is my chain:
embedding = ZhipuAIEmbeddings(zhipuai_api_key=api_key)
vectordb = Chroma(persist_directory=persist_directory, embedding_function=embedding)
llm = ZhipuAILLM(model="glm-4", zhipuai_api_key=api_key,temperature=0)
retriever = vectordb.as_retriever(search_type="similarity", search_kwargs={"k": 6})
qa_interface = RetrievalQA.from_chain_type(
llm,
chain_type="stuff",
retriever=retriever,
return_source_documents=True,
)
I want the function "qa_interface()" instead of self._aask() for compatibility, and sincerely ask for your help

Zhipu embedding seems not yet supported by Llama Index, need to create a custom embedding and pass to embed_model.
For more info, you can take a look at RAG Module.

@seehi can you add some documentation to clarify this issue?
