LLM Cost Optimization: Your Bill Is an Architecture Problem, Not a Prompt Problem

This story was originally published on HackerNoon at: https://hackernoon.com/llm-cost-optimization-your-bill-is-an-architecture-problem-not-a-prompt-problem. Cut LLM inference costs with architecture-first techniques: model routing, context optimization, prompt caching, semantic caching, batching, and observability.

Most LLM cost problems cannot be solved by trimming a few words from a prompt. The bigger savings come from architecture: measure every call, route simpler tasks to smaller models, control context growth, design for prompt caching, use semantic caching carefully, batch asynchronous workloads, limit unnecessary output, and put budgets around retries and agents. Most importantly, optimize cost per useful outcome, not simply token spend.
