Sakana’s Fugu Ultra v2 turns model choice into the model
Most AI systems still make you bet on one giant model. Fugu Ultra v2 takes the opposite route: it learns to route difficult, multi-step work across a fixed pool of open and specialized models, then recursively calls its own orchestrator when needed. That makes capability less dependent on any single vendor, while its sibling Fugu Max pushes the same architecture toward lower cost.
