Exercise

Creating a RAG chain

Now to bring all the components together in your RAG workflow! You've prepared the documents and ingested them into a Chroma database for retrieval. You created a prompt template to include the retrieved chunks from the academic paper and answer questions.

The prompt template you created in the previous exercise is available as prompt_template, an OpenAI model has been initialized as llm, and the code to recreate your retriever has be included in the script.

Instructions

100 XP
  • Create an LCEL chain using the pipe operator (|) to connect retriever, prompt_template, and llm in sequence.
  • The chain should map the retriever to "context" and user input to "question".
  • Invoke the chain using the .invoke() method on the question provided.
