Fugu Max is the cost-performance tier of Sakana AI's Fugu family: like Fugu Ultra v2, OpenRouter describes it as a learned multi-agent orchestration system rather than a single checkpoint, routing requests across models behind a 1M-token-context endpoint. It is proprietary and priced well below Fugu Ultra v2, fitting routine and moderately difficult coding and interactive tasks.
