-Caching is the highest-ROI optimization for AI agents. By intercepting repeated or similar requests before they reach the LLM, production systems eliminate **20-45% of API calls** entirely.

-Agents are expensive by nature: a single user query can trigger 3-8 LLM calls across planning, tool use, and synthesis steps. Without caching, identical or near-identical workflows execute from scratch every time.
