About
Sakana Fugu is a multi-agent orchestration system from Tokyo-based Sakana AI, delivered as a single model through an OpenAI-compatible API. A trained conductor model breaks each request into sub-tasks and delegates them to a swappable pool of frontier LLMs — including recursive calls to itself — then verifies and synthesizes one response. Fugu is the lower-latency tier for everyday work like coding and chat, while Fugu Ultra coordinates a deeper agent pool for hard multi-step reasoning; both offer a 1M-token context window. The service is not yet available in the EU/EEA.
Create an account and API key via Sakana AI's console at https://sakana.ai/fugu, then point any OpenAI-compatible client at the Fugu endpoint. To use Fugu inside Claude Code or Codex, run the official one-line installer from Sakana AI's GitHub repo: curl -fsSL https://sakana.ai/fugu/install | bash, then launch claude-fugu or codex-fugu.
