Echo by Tracer

Echo combines specialist open-weight models into one system, allocating compute where it improves the result. Echo is now live: one model name and one OpenAI-compatible endpoint for chat, code, and agents.

Echo is powered by adaptively coordinated open-weight models behind one stable interface. It adapts the capabilities and computation to each request.

1. Talk to one model: Questions, careful analysis, math, and code share the same conversation.
2. Keep your OpenAI client: Set Echo's base URL, model name, and API key. Echo adapts behind the same stable interface.
3. Use Echo across the agent loop: Point OpenCode and other compatible harnesses at Echo. The harness keeps its tools and loop; Echo adapts inside each model call.

Emergence is a research hypothesis until a coordinated system beats its strongest component. We measure the whole against that bar.

1. Paired comparisons: Same task. Same harness. Echo against the strongest single-model baseline measured in that cohort.
2. Whole-system economics: Quality, latency, and cost recorded end to end under explicit, consistent accounting rules.
3. Auditable evidence: Dated cohorts, explicit denominators, reproducible artifacts, and visible limitations.
