Sakana Fugu Ultra Joins Vercel AI Gateway With No Markup
Sakana Fugu Ultra just made its debut on Vercel AI Gateway. This means developers can now tap into one of the most capable AI models available, and they won’t pay any extra fees to do it.
Unlike most AI models, Sakana Fugu Ultra doesn’t run as a single system. Instead, it pulls from a pool of publicly accessible frontier models. As a result, it routes each task to one to three agents, depending on the complexity of the problem. Then, it merges their answers into one final response.
According to reasoning and science benchmarks, Sakana Fugu Ultra performs on par with Claude Mythos Preview and Fable 5. That puts it firmly in frontier territory, and many developers will likely take notice.
Getting started is simple. Developers just need to set the model to sakana/fugu-ultra inside the AI SDK. From there, they can stream responses straight into their applications.
Meanwhile, Vercel AI Gateway continues to expand its toolkit. The platform offers a single API for calling models, tracking usage, and managing costs. It also supports retries, failover, and performance tuning, which together push uptime higher than most individual providers offer.
Additionally, the Gateway includes built-in custom reporting, Zero Data Retention support, and budget controls for API keys. So, teams get more visibility and more control over their AI spending.
Notably, Vercel reflects provider pricing with zero markup. This applies across the board, including Bring Your Own Key requests. Therefore, cost-conscious teams can scale their AI use without worrying about hidden platform fees.
Developers curious about Sakana Fugu Ultra can try it directly in the model playground. Given its multi-agent design and frontier-level performance, it may quickly become a popular pick on the Gateway’s model leaderboard.
