Disclaimer for Fugu AI – Sakana Fugu

Last updated: June 2026

This Disclaimer governs your use of the Fugu AI orchestration system (also referred to as “Sakana Fugu” or “FUGU”) and the website fugubysakana.store. By accessing or using our services, you acknowledge and agree to the terms outlined below.

General Information Only

The content provided on this website and through the Fugu AI API is for general informational and operational purposes only. While we strive to keep information accurate and up to date, we make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability, or availability of the AI outputs, system performance, or any related materials.

No Professional Advice

Fugu AI is an orchestration model that synthesizes outputs from multiple third-party AI systems. It does not provide legal, financial, medical, or other professional advice. You should not rely on any output from Fugu AI as a substitute for consultation with qualified professionals. Any decisions you make based on system outputs are your sole responsibility.

Limitation of Liability

To the fullest extent permitted by applicable law, Sakana AI, its co-founders, affiliates, and operators of fugubysakana.store shall not be liable for any direct, indirect, incidental, consequential, or punitive damages arising from or related to:

  • Your use or inability to use the Fugu AI system or API
  • Any errors, omissions, or inaccuracies in AI-generated outputs
  • Delays, slow response times, or underwhelming performance in practical tests
  • Interruptions or unavailability of the service due to technical issues, export controls, or regulatory restrictions
  • Reliance on the “collective intelligence” of third-party models, including GPT-5.5, Gemini 3.1 Pro, and Claude Opus 4.8
  • Vendor lock-in, geopolitical export controls, or changes in access to frontier models

You assume all risk for any results or outcomes derived from using Fugu AI.

No Guarantee of Performance

While Sakana AI’s technical reports indicate that Fugu Ultra achieves competitive benchmark scores (e.g., 73.7 on SWE-Bench Pro and 95.5 on GPQA-Diamond), we do not guarantee that your specific use case will achieve similar results. Performance may vary based on task complexity, input quality, and the availability of underlying third-party models. Independent validation of claims is encouraged.

Third-Party Models and Content

Fugu AI dynamically delegates sub-tasks to publicly available frontier models. We do not control the outputs, accuracy, or behavior of these third-party systems. Any content generated through Fugu AI may reflect the biases, limitations, or errors of the underlying models. We disclaim all liability for content produced by third-party AI systems.

Geographic and Regulatory Restrictions

Fugu AI is currently offered as a proprietary API and is restricted in the EU/EEA due to GDPR compliance requirements. If you access our services from a restricted region, you do so at your own risk and are responsible for compliance with local laws. We make no representation that our services are appropriate or available for use in all jurisdictions.

Pricing and Subscriptions

Pricing, including the $5 per million input tokens and $30 per million output tokens for Fugu Ultra, as well as any subscription plans, is subject to change without notice. We are not liable for any losses incurred due to pricing changes, billing errors, or service tier modifications.

User Responsibility

You are solely responsible for:

  • Ensuring your use of Fugu AI complies with all applicable laws and regulations
  • Evaluating the suitability of AI outputs for your intended purpose
  • Protecting your own data and intellectual property when using the API
  • Verifying any claims or performance metrics through independent testing
