Independent and unofficial

fugu-ai.com is an independent guide site. It is not affiliated with, endorsed by, sponsored by, or in any way officially connected to Sakana AI Co., Ltd. or any of its products. All information here is published for general reference.

Trademarks

Sakana, Sakana AI, Fugu, and Namazu, as well as all other product names mentioned on this site — including ChatGPT, Claude, and Gemini — are trademarks of their respective owners. They are used on this site for identification and commentary only. We do not use Sakana AI’s logo or artwork; all diagrams and images are our own original work.

Pricing, benchmarks, and dates

Prices, plan allowances, and benchmark figures on this site are accurate as of the date stamped on each page and can change without notice. Benchmark scores are reported by the vendors that published them; we do not independently verify them. Before spending money, always confirm current figures on the official pricing page.

No professional advice

Nothing on this site constitutes legal, financial, or security advice. Content about security-oriented AI tools describes official access processes and legitimate defensive uses only.

Eligibility for third-party services

The services we cover set their own eligibility rules — for example, Sakana’s terms require users to be at least 18 and do not offer the service in certain regions. Nothing on this site changes, or should be read as encouraging you to bypass, those rules.
