General Information

The information provided by Sakana Fugu AI (accessible at fuguai.online) is for general informational and educational purposes only. All content, outputs, and services are provided on an “as is” and “as available” basis without any representations or warranties of any kind, express or implied.

No Professional Advice

The content generated by Fugu AI, including outputs related to Japanese Mythos5 and Fable5, does not constitute professional advice (legal, financial, medical, or otherwise). You should not rely solely on AI-generated outputs for critical decisions. Always consult qualified professionals for specific guidance tailored to your situation.

Limitation of Liability

To the fullest extent permitted by applicable law, Sakana AI, its co-founders, affiliates, and licensors shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the Fugu AI system, including but not limited to:

  • Errors, omissions, or inaccuracies in generated content
  • Loss of data, revenue, or business opportunities
  • Reliance on outputs for coding, research, cybersecurity, or patent analysis
  • Delays, slow response times, or underwhelming performance in practical tests
  • Any damages resulting from vendor lock-in, geopolitical export controls, or restricted model access

No Warranty Regarding Performance

While Sakana Fugu AI claims performance comparable to leading restricted models on benchmarks such as SWE-Bench Pro (73.7) and GPQA-Diamond (95.5), we make no guarantees that actual results will match these benchmarks in your specific use case. Independent validation may vary, and user experiences—including reports of slow response times—should be considered when evaluating the system.

Third-Party Models and Outputs

Fugu AI orchestrates outputs from publicly available frontier models including GPT-5.5, Gemini 3.1 Pro, and Claude Opus 4.8. We do not control, endorse, or assume responsibility for the accuracy, legality, or appropriateness of content generated by these third-party models. The system intentionally omits restricted models such as Claude Mythos Preview and Fable 5 from its agent pool.

Commercial Availability and Restrictions

Fugu AI is currently offered as a proprietary API. Access is restricted in the EU/EEA due to GDPR compliance requirements. Pricing for Fugu Ultra is $5 per million input tokens and $30 per million output tokens, with additional subscription plans available. Availability and pricing are subject to change without notice.

Content Usage

You are solely responsible for how you use content generated by Fugu AI. You must comply with all applicable laws, regulations, and third-party rights. We disclaim any liability for misuse of outputs, including but not limited to copyright infringement, defamation, or violation of export controls.

No Endorsement

References to any third-party products, services, or organizations (including Anthropic, Google, or OpenAI) do not imply endorsement by or affiliation with those entities. All trademarks are property of their respective owners.

We reserve the right to update or modify this disclaimer at any time. Changes will be posted on this page with an updated “Last updated” date. Your continued use of the service after changes constitutes acceptance of the revised terms.
