🐡 One day a regulation changes and the model you depend on loses its API overnight—that reality lays bare the risk of single-vendor dependence in AI.
Export controls on Fable and Mythos showed access can be cut in an instant. So rather than betting everything on one giant model, maybe the resilient blueprint for AI sovereignty is collective intelligence: many models, orchestrated to collaborate. That is the question Sakana AI poses.
Its answer is Sakana Fugu: One Model to Command Them All. Fugu isn't a mere router—it's a language model trained to call various LLMs in an agent pool. You send a request to one endpoint, and Fugu decides whether to solve it directly or assemble a team of specialized models, handling selection, delegation, verification, and synthesis internally. It calls itself recursively, and because agents in the pool are swappable, it can dynamically route around restricted models—the crux of "sovereignty." It builds on Trinity and Conductor (ICLR 2026), running on learned orchestration rather than fixed workflows.
🚀 The accuracy-focused Fugu Ultra stands shoulder-to-shoulder with Fable 5 and Mythos Preview on rigorous reasoning, science, and engineering benchmarks, and on some tasks beats Gemini 3.1 Pro, Opus 4.8, and GPT 5.5. Among 500 beta users, a code reviewer found more than twenty issues where competitors flagged about three, and data-science research progressed with little human intervention. From monolithic scaling toward a collaborative ecosystem.
