How to Download Sakana Fugu AI

This guide will walk you through downloading Sakana Fugu AI from our website. Follow these simple steps to get started with the Fugu or Fugu Ultra variant.

Step 1: Visit the Official Website

Open your web browser and go to the Sakana AI official website. Look for the “Products” or “Fugu AI” section on the homepage.

Step 2: Choose Your Variant

On the Fugu AI page, you will see two options:

  • Standard Fugu – Best for everyday coding, chat, and general tasks. It balances performance and speed.
  • Fugu Ultra – Designed for complex challenges like AI research, cybersecurity analysis, and patent investigation. It uses a deeper pool of expert models for higher accuracy.

Click the “Get Started” or “Learn More” button under your preferred variant.

Step 3: Create an Account

You will be prompted to sign up. Provide your email address and create a password. You may also need to verify your email by clicking a link sent to your inbox.

Step 4: Select a Plan

After logging in, you will see available subscription plans. Fugu Ultra costs $5 per million input tokens and $30 per million output tokens. Standard Fugu pricing may vary. Choose the plan that fits your needs and complete the payment process if required.

Step 5: Access the API Key

Once your account is active, navigate to the “API Keys” or “Dashboard” section. Click “Generate New Key” to create your unique API key. Copy this key and store it securely – you will need it to connect to the service.

Step 6: Download the Client Library (Optional)

For easier integration, you can download the official client library. On the same dashboard, look for a “Downloads” or “SDK” section. Choose your programming language (e.g., Python, JavaScript) and download the library. Alternatively, you can use the OpenAI-compatible API endpoint directly with your existing tools.

Step 7: Start Using Fugu AI

With your API key and client library ready, you can now send requests to the Fugu AI system. Follow the documentation provided on the website to make your first call. The system will automatically delegate sub-tasks to frontier models like GPT-5.5, Gemini 3.1 Pro, and Claude Opus 4.8, then synthesize the results for you.

Important Notes

  • Fugu AI is currently offered as a proprietary API. There is no standalone software to install on your device.
  • The service is restricted in the EU/EEA due to GDPR compliance. Check availability in your region before signing up.
  • Some users report slower response times for complex tasks. Test the system with your specific workflow to evaluate performance.
