Design a high-level system for Gemini responding to a user query.

Focus on outlining the key components of the system that will handle user queries for Gemini. Start by identifying the user input methods, such as voice or text, and how these inputs will be processed. Detail the architecture, including data storage, processing layers, and any machine learning models that might be involved in understanding and responding to the queries. Consider how the system will ensure scalability, reliability, and low latency in responses. Additionally, think about how you would incorporate user feedback to improve the system over time.
