Frequently Asked Questions

What is Sakana Fugu?
Sakana Fugu is a multi-agent AI orchestration system by Sakana AI that coordinates multiple frontier language models (GPT, Claude, Gemini) behind a single OpenAI-compatible API endpoint. Instead of relying on one model, Sakana Fugu dynamically assembles and directs a pool of specialized AI agents to solve complex tasks with frontier-level performance.
How is Sakana Fugu different from ChatGPT or Claude?
ChatGPT and Claude are single-model products — you get one model per request. Sakana Fugu is fundamentally different because it orchestrates multiple models simultaneously. When you send a request to Sakana Fugu, a trained conductor model decides which experts to activate, assigns roles (Thinker, Worker, Verifier), and coordinates their outputs into one response that often surpasses any single model.
What models does Sakana Fugu use behind the scenes?
Sakana Fugu coordinates a pool of frontier models including GPT-5.5, Claude Opus, Gemini 3.1 Pro, and instances of itself recursively. The exact model routing is proprietary — Sakana Fugu's conductor model dynamically selects which agents to activate based on the specific task. With Sakana Fugu (balanced), you can opt out specific agents for compliance reasons.
Is Sakana Fugu available in the EU?
No, Sakana Fugu is currently unavailable in EU/EEA member states. Sakana AI states that GDPR compliance is in progress. Users in the EU cannot access Sakana Fugu's API or subscription plans at this time. Check the official Sakana Fugu console for updates on regional availability.
How much does Sakana Fugu cost?
Sakana Fugu offers three subscription tiers: Standard at $20/month for lightweight usage, Pro at $100/month for 10x usage, and Max at $200/month for 20x heavy workloads. Sakana Fugu also offers pay-as-you-go API pricing: Fugu Ultra costs $5/1M input tokens and $30/1M output tokens. Subscribe before July 2026 for one free month.
Can I use my existing OpenAI code with Sakana Fugu?
Yes. Sakana Fugu provides an OpenAI-compatible API endpoint. If your application already calls GPT, Claude, or Gemini via the OpenAI SDK format, you can switch to Sakana Fugu by changing the endpoint URL and API key — no SDK migration or code rewrite required. Sakana Fugu handles all model coordination transparently.
What is the difference between Sakana Fugu and Fugu Ultra?
Sakana Fugu (balanced) optimizes for a balance of performance and latency, making it ideal for everyday coding, chat, and review tasks. Sakana Fugu Ultra maximizes answer quality by coordinating deeper expert agent pools — it is designed for Kaggle competitions, research paper reproduction, security analysis, and complex multi-step reasoning where quality trumps speed.
What research is behind Sakana Fugu?
Sakana Fugu is built on two peer-reviewed ICLR 2026 papers: TRINITY (an evolved LLM coordinator that assigns Thinker, Worker, Verifier roles) and the Conductor (which uses reinforcement learning to discover natural-language coordination strategies). The Sakana Fugu conductor is a 7B parameter model trained to orchestrate much larger frontier models.
Does Sakana Fugu store my data?
Sakana Fugu usage data is used to improve performance by default, but you can opt out anytime via the Sakana Fugu console settings. Model routing information (which agents handled your request) is not disclosed. Sakana Fugu provides real-time token usage and cost tracking per request through the API response headers.
How often is Sakana Fugu updated?
Sakana AI evaluates new frontier models on approximately a 2-week cycle. When a new model releases (like a new GPT or Claude version), Sakana Fugu's agent pool is updated to include it after evaluation. This means Sakana Fugu automatically benefits from improvements across the entire AI ecosystem without you changing anything.

About This Sakana Fugu Guide

This Sakana Fugu guide is an independent resource maintained to help developers, researchers, and AI users understand Sakana AI's multi-agent orchestration product. We compile information from Sakana AI's official announcements, technical papers (TRINITY and the Conductor, both ICLR 2026), and publicly available benchmark data.

We aim to present Sakana Fugu information accurately and objectively, including both its strengths (multi-agent orchestration, benchmark performance) and its current limitations (no EU availability, new product without long track record). For the most up-to-date Sakana Fugu information, we recommend checking the official Sakana AI website at sakana.ai.

If you have a question about Sakana Fugu that is not answered above, contact the Sakana Fugu support team directly at fugu-support@sakana.ai. For Sakana Fugu account and billing questions, visit the Sakana Fugu console at console.sakana.ai.
