AI Foundations: Retrieval Augmented Generation (RAG) Lab

Within step 6, the instruction says after creating the Knowledge base "My Intellectual Property" folder, xto change the chuck size to 65 however a Warn is displayed saying, "Please add both embedding model and LLM in the setting>Model provider fist.  then set them in the "set default models'.    After selecting the Ok button, I try to add vai the Set default model but then see this...  

"The default embedding model for each newly created knowledge base. If you cannot find an embedding model from the dropdown, check if you are using RAGFlow slim edition (which does not include embedding models) or check https://ragflow.io/docs/dev/supported_models to see if your model provider supports this model."

Not sure how to address/resolve, any assistance will be helpful.

Thank you,

Tony
