# Fugu

> Fugu is Sakana AI's orchestration model, balancing strong performance with low latency. Rather than answering directly, it routes a task across a pool of expert agents and frontier models behind one OpenAI-compatible API, then synthesizes the result. Platform usage bills at the standard rate of the underlying model that Fugu selects, so effective cost varies per request. It supports OpenAI-compatible Chat Completions and Responses APIs, including built-in tools such as web_search.
