{"slug": "new-model-available-fugu-ultra-v2", "title": "New Model Available: Fugu Ultra v2", "summary": "Sakana AI released Fugu Ultra v2, a higher-performance model in its Fugu family that functions as a learned multi-agent orchestration system rather than a single monolithic model. Fugu Ultra v2 routes tasks across a fixed pool of open and specialized models and recursively calls instances of itself, prioritizing answer quality on complex multi-step reasoning, autonomous research, and full-stack software development without relying on individual proprietary frontier models. It supports configurable reasoning effort (high, xhigh, max), function calling, structured outputs, image and PDF input, and built-in web search, with prompts above 272K tokens billed at a higher rate and orchestration tokens billed as standard input/output tokens.", "body_md": "Fugu Ultra v2 is the higher-performance model in Sakana AI's Fugu family.
