Summary: Sakana AI introduced Fugu, a multi-agent orchestration service exposed through an OpenAI-compatible API that routes a task across multiple LLMs assigned Thinker, Worker, and Verifier roles. It is built on two ICLR 2026 papers, TRINITY (a lightweight evolved coordinator) and Conductor (reinforcement learning over natural-language coordination strategies), and ships in Fugu and Fugu Ultra variants. Vendor product page; no independent evaluation.
Why it matters: Packaging mixture-of-agents routing behind one API surface lowers the integration cost of orchestrating several models for multi-step tasks.
