Developer builds RRC Gateway to cut LLM costs by caching answers

By PulseAugur Editorial · [1 sources] ·

A developer has created RRC Gateway, a proxy service designed to reduce costs associated with using large language models. The gateway addresses three primary areas of expense: duplicate prompts that are answered repeatedly, excessive context window usage, and the deployment of premium models for trivial tasks. By implementing semantic caching, virtual memory for context compression, and smart routing to cheaper models for simpler queries, the service aims to significantly cut down API call costs. AI

IMPACT Could significantly reduce operational costs for applications heavily reliant on LLM APIs by optimizing prompt and model usage.

    <h1> I Kept Paying for the Same AI Answers — So I Built a Gateway That Caches Them </h1> <p>Last month I looked at our OpenAI bill and felt sick. Not because the number was huge — because I recognized the <em>questions</em>. We were paying full price, every single day, for answer…
