Multi-Modal Knowledge Assistant

Design a multi-modal knowledge assistant that can answer user questions using both text and images. The assistant should be able to retrieve information from a structured knowledge graph and utilize a database of images. Consider how to manage data ingestion, embeddings for text and images, and how to ensure accurate retrieval of relevant information. Discuss model choice, evaluation criteria for the quality of responses, latency issues, cost implications, safety mechanisms to filter inappropriate content, and monitoring for drift in performance.
