Tracer

The page outlines a sequence for AI startups: find product-market fit with the strongest model, add observability from the first call, then route repetitive traffic to a low-cost model.

Field notes on routing LLM traffic to cheap models with guarantees: what works, what fails, and the numbers behind it.

Agents spend most of their tokens deciding which tool to call next. That decision repeats. Route it through a small classifier and cut end-to-end agent cost without changing the agent's behaviour.

The page describes routing certifiable support-ticket intents to a small classifier and deferring other requests to an LLM to reduce costs while maintaining accuracy.

Tracer is a YC-backed research lab that helps AI teams improve performance per token through intelligence allocation and coordination. Echo is Tracer's latest product.

Tracer ML’s Echo orchestration is presented as comparing an open-weight ensemble with frontier models on cost and quality. The headline asks whether it can deliver Claude-class performance for one-third the price.
