Sakana AI unveiled Fugu Max and Fugu Ultra v2, the next evolution of its multi-agent orchestration system, arguing the frontier that matters is the Pareto frontier of capability vs cost.
- Fugu Max orchestrates its largest pool of open-weights and specialized models yet (including the NVIDIA Nemotron family), dynamically routing tasks to the leanest capable model — near-elite performance at 2-6x lower cost.
- Fugu Ultra v2 pushes peak capability higher, outperforming Opus 5 and Fable 5 on Chartography and beating top models on DeepSWE.
A live demo and blog post are available.
