Fugu Ultra v2 is the top model of Sakana AI's Fugu family, and it is not a single model: a trained orchestrator sends parts of each task to a fixed pool of open and specialised models and can call copies of itself. The Ultra version puts answer quality first, for complex multi-step reasoning, autonomous research and full-stack software development. It supports image and PDF input and built-in web search; very long prompts are billed at a higher rate.

It accepts text, image and file (PDF) input and returns text, and supports tool calling, structured JSON output and streaming. It always reasons before answering, and you choose how hard it thinks with the reasoning effort setting. Fugu Ultra v2 is commonly used for autonomous research, full-stack development, complex multi-step reasoning and deep analysis. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $5 per million input tokens and $30 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
