Intelligent Token Compression Middleware for LLM APIs

P6/10April 5, 2026

WhatAn API proxy layer that automatically compresses prompts and responses to minimize token usage while preserving output quality, sitting between applications and LLM providers.

SignalDevelopers are actively seeking ways to reduce token costs in production LLM applications, and a system prompt that claims 75% token reduction on outputs has generated significant excitement and engagement.

Why NowLLM API costs remain a major line item for AI-native startups, and as models get more capable the volume of API calls is exploding — but pricing hasn't dropped proportionally, creating urgent demand for optimization layers.

MarketEvery company making LLM API calls pays for tokens; the LLM API market is $10B+ and growing fast. Competitors like prompt caching (offered by providers) address a different angle — no one owns the compression-at-the-edge layer yet.

MoatProprietary compression models trained on millions of prompt-response pairs would improve over time, creating a data flywheel that new entrants can't replicate.
