## TL;DR

Prompt caching has become a vital strategy for managing rising LLM operating costs.

---

## Summary

Prompt caching has become a vital strategy for managing rising LLM operating costs. By reusing previously computed data it minimizes redundant computation, cutting both expense and latency. Key techniques like KV caching store and reuse key-value vectors, bypassing the costly prefill step for repeated context.

## Nauti's Take

Prompt caching is one of the most concrete opportunities to cut LLM bills hard without sacrificing quality, especially for workflows with repeating context. The risk: caches only pay off when prompts are consistently structured and privacy isn't compromised by leaked system prompts. Teams managing token budgets should evaluate KV and prefix caching deliberately instead of flipping it on globally.
