# Sakana Fugu: The Multi-Agent AI System That Works Like a Team
We’ve all been there: copy-pasting a prompt from ChatGPT to Claude, and then to Gemini, trying to find which AI gives the best answer.
Different AI models have different strengths. Some are excellent programmers, some write beautifully, and others are master logicians. But constantly switching between them is slow and frustrating.
Sakana AI has introduced a brilliant solution: Sakana Fugu.
Fugu is a multi-agent AI system that bundles multiple frontier models into a single, seamless package. To you, it looks like a single chatbot. But behind the scenes, it acts as a project manager, coordinating a team of top-tier AI models to solve your task.
What is Sakana Fugu?
Sakana Fugu is a collaborative AI framework. Instead of relying on one massive AI model to do all the work, Fugu orchestrates a pool of specialized models (such as GPT-5, Claude Opus, and Gemini Pro).
When you give Fugu a complex, multi-step prompt, it:
- Analyzes the task and breaks it down into steps.
- Assigns specialized roles (like researcher, coder, and editor) to different AI models.
- Passes the work back and forth between them until the final, polished result is ready.
By working as a team, these models achieve far better results than any single AI could on its own.
The Secret Sauce: Teamwork Over Size
Fugu’s intelligent coordination is based on two core concepts presented at the ICLR 2026 conference:
1. The Manager (TRINITY)
Think of TRINITY as the manager of the team. It is a compact coordinator model that assigns specific roles to the worker LLMs. For example, it might tell Gemini to generate the initial code, tell Claude to find the bugs, and tell GPT to write the user documentation. They collaborate seamlessly without needing to merge their code bases.
2. The Conductor
The Conductor acts as the communication network designer. It figures out the best way for the worker AIs to talk to each other for your specific question. It writes custom instructions for each worker model, discovering collaboration strategies that human designers might never have thought of.
Why Fugu is the Future of AI
Fugu represents a major shift in how we use artificial intelligence:
- It is Future-Proof: When a new, more powerful LLM is released, Sakana AI simply adds it to Fugu’s model pool and updates the coordinators. Fugu gets smarter automatically, while your API endpoint remains exactly the same.
- Superior Reasoning: Collaborative AI excels at complex, multi-step problem solving where single models often get lost or make mistakes.
- Easy to Use: You don't need to know how to build complex agent networks. You just call one API, and Fugu handles all the heavy lifting.
Getting Started with Sakana Fugu
For developers on macOS or Ubuntu, you can install Fugu locally with a single terminal command:
curl -fsSL https://sakana.ai/fugu/install | bash
Once installed, you can start it by running:
codex-fugu
The Verdict
Sakana Fugu is proof that the future of AI isn't just about building bigger models—it's about teaching AI how to work together. By organizing different models into a cooperative team, Fugu delivers a smarter, faster, and more accessible AI experience for everyone.
