In this video, we build a retrieval-augmented generation chatbot to query PDF files (research articles in this case). We use LangChain for orchestration, a Hugging Face model for embeddings, Chroma for vector search, Gradio for the user interface, and Arcee Conductor to optimize inference. We first run a local version and then push it to a Hugging Face Space.

Arcee Conductor (arcee.ai/product/arcee-conductor) is an inference platform that intelligently routes any query to the best model, efficiently delivering precise and cost-effective results for any task.

If you’d like to understand how Arcee AI can help your organization build scalable and cost-efficient AI solutions, don't hesitate to contact sales@arcee.ai or book a demo at arcee.ai/book-a-demo.
