Q: What is Echo?

Echo is a code AI tool listed on Use AI Tools. Echo is an AI system from Tracer built by pooling open-weight models instead of relying on a single hosted one. The launch post describes it as reaching Fable-level results at roughly a third of the cost, by routing work across a pool of models. It is aimed at developers who want frontier-adjacent coding performance without paying frontier API prices. Access runs through a hosted sign-in, so you use it as a service rather than running it locally.
