Fugu Ultra is the higher-performance model in Sakana AI's Fugu family. Rather than a single monolithic model, Fugu is a learned multi-agent orchestration system: a language model trained to route tasks across a swappable pool of underlying models and to recursively call instances of itself.

Fugu Ultra prioritizes answer quality on complex, multi-step reasoning, coding and agentic workflows. It supports configurable reasoning effort, tool calling and built-in web search. Orchestration tokens consumed by the system are billed as standard input/output tokens. Hormouz exposes an OpenAI-compatible API. Point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs unchanged.

Pricing is usage-based: $5/M in · $30/M out. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
