Sakana Fugu

Sakana Fugu is an API that orchestrates multiple AI models to handle complex coding, research, reasoning, and security tasks.

Sakana Fugu

Sakana Fugu coordinates specialized AI agents through one OpenAI-compatible API. It offers Fugu, Fugu Ultra, Fugu Max, and Fugu Cyber for different balances of latency, quality, cost, and cybersecurity focus.

It is used by developers, researchers, security teams, and enterprises for coding, code review, paper reproduction, research, vulnerability analysis, and agent workflows. Usage is paid through monthly subscriptions or token-based billing; Fugu Cyber requires access approval, and service is unavailable in the EU/EEA.
