Sakana Fugu

Sakana AI's orchestration 'model': one OpenAI-compatible API (Fugu, plus the deeper Fugu Ultra) that is actually a trained coordinator assembling a pool of other labs' frontier models, assigning roles, verifying, and synthesizing one answer. Built on the TRINITY + Conductor ICLR 2026 papers. The routing is a black box you cannot inspect; intelligence is borrowed from the underlying models. Not available in the EU/EEA yet.
