# LLM Token Cost Optimizer

LLM Token Cost Optimizer is a product idea in the devtools category at difficulty 3/5, with strong market demand and an estimated revenue potential of $2k-10k/mo.

## Summary

A caching and deduplication layer that sits between your app and LLM APIs (OpenAI, Claude, etc.), reducing costs by detecting semantic similarity in prompts. Saves companies 50-80% on API bills without changing their code.

## Why this is interesting

LLM API costs are a genuine pain point right now as companies scale inference workloads beyond prototype stage, and the push to cut AI infrastructure spend without sacrificing output quality is real and growing. GPTCache is the closest open-source substitute, and the fact that most teams either don't know it exists or lack the ops bandwidth to self-host it is the actual wedge here. The $2k–10k/mo revenue band is plausible for early SMB customers but likely undersells the ceiling — a single mid-size company saving $20k/month on OpenAI bills would happily pay $2k/month, so pricing discipline matters more than the band implies. The biggest risk is that OpenAI and Anthropic build native prompt caching into their APIs at the infrastructure level — which OpenAI has already started doing with their prompt caching feature — making the core value proposition obsolete before you've established enough lock-in.
