It coordinates several models, routing work to 1-3 agents depending on the problem and combining their results into a single answer.\n\nBased on reasoning and scientific benchmarks, Fugu Ultra has capabilities similar to those of Claude Mythos Preview and Fable 5.\n\nTo use Fugu Ultra, set `model`\n\nto `sakana/fugu-ultra`\n\nin [AI SDK](https://ai-sdk.dev/):\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [custom reporting](https://vercel.com/changelog/custom-reporting-ai-gateway), [Zero Data Retention support](https://vercel.com/blog/zdr-on-ai-gateway), [budgets for API keys](https://vercel.com/docs/ai-gateway/authentication-and-byok/api-keys), and more.\n\nAI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.\n\nTry Sakana Fugu Ultra in the [model playground](https://vercel.com/ai-gateway/models/fugu-ultra).", "url": "https://wpnews.pro/news/sakana-fugu-ultra-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/sakana-fugu-ultra-now-available-on-ai-gateway", "published_at": "2026-06-22 00:00:00+00:00", "updated_at": "2026-06-22 07:40:14.810086+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-tools", "ai-infrastructure"], "entities": ["Sakana AI", "Sakana Fugu Ultra", "AI Gateway", "Vercel", "Claude Mythos Preview", "Fable 5", "AI SDK"], "alternates": {"html": "https://wpnews.pro/news/sakana-fugu-ultra-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/sakana-fugu-ultra-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/sakana-fugu-ultra-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/sakana-fugu-ultra-now-available-on-ai-gateway.jsonld"}}
