AI Interview Questions #3 - Prompt Caching with LLMs

Why watch

This video explains prompt caching techniques for LLMs as a real interview question from big tech companies. It covers two main approaches: exact query caching (matching identical prompts) and semantic caching (using vector embeddings to match similar prompts). The content is designed for software engineers preparing for AI engineering interviews who want to understand caching strategies for optimizing LLM API costs and performance.
