Answer: Invite users to submit long, rather than concise, questions
The question asks which component is NOT useful for building a question-answering chatbot. Option A (inviting users to submit long questions) is counterproductive as concise questions are typically easier for chatbots to process and understand. The other options are essential: B (response-generating LLM) generates answers, C (embedding model) converts text to vectors for semantic search, and D (vector database) stores and retrieves relevant document embeddings efficiently. Community discussion shows 67% support for A, with the highest upvoted comment explicitly selecting A, confirming it as the unnecessary component.
