Sakana AI launches Fugu models for multi-agent orchestration

Sakana AI released Fugu Max and Fugu Ultra v2, two models sharing a learned orchestration architecture that routes tasks across lean open and specialized models, including Nvidia Nemotron. Fugu Max costs $2/$6 per million tokens, while Fugu Ultra v2 targets peak capability, scoring 48.3 on Chartography and 74.3 on DeepSWE.

Why it matters: Instead of building ever-larger single models, this bets on learned routing across a mix of smaller specialized models, a cheaper architecture that could matter if it holds up on real-world tasks, since it decouples capability gains from constantly training bigger foundation models.
