So sánh

Fugu Ultra v2 is the higher-performance tier of Sakana AI's Fugu family: rather than a single trained checkpoint, OpenRouter describes it as a learned multi-agent orchestration system that routes each request across a pool of models, exposed here with a 1M-token context. It is proprietary and priced at the top of the Fugu line, aimed at the hardest coding, reasoning, and tool-use tasks where Fugu Max's lower cost is not enough.
