Sakana AI ships Fugu Max and Fugu Ultra v2 to push the cost-performance Pareto frontier
hardmaru · x · 2026-09-11
Sakana AI (hardmaru) released Fugu Max and Fugu Ultra v2, two flavors of the same orchestration architecture: Fugu Max targets the best output at the lowest cost, while Fugu Ultra v2 maximizes capability on complex multi-step tasks without indispensable reliance on the frontier models it orchestrates.
- Thesis: the industry has raced on one axis (bigger, pricier foundation models), but the frontier that matters is 2D — capability vs cost; orchestration that picks the right machinery per task beats monolithic huge models.
- By orchestrating a large pool of open and specialized models, Fugu extends the cost-performance Pareto frontier beyond what any single model reaches.
- Timeline: April beta proved multi-agent orchestration as a unified foundation model; June GA + Fugu Ultra v1 showed the orchestration layer can match closed frontier models on benchmarks.
