Sakana AI Launches Fugu and Fugu Ultra — an Orchestration 'Model' That Routes Around the Fable 5 Export Ban

Sakana AI·high signal

Tokyo's Sakana AI launched Fugu and Fugu Ultra on June 22: an orchestration system that presents a single OpenAI-compatible API while internally routing each task across a swappable pool of frontier LLMs, dynamically and without hardcoded rules. CEO David Ha framed it explicitly as a hedge against single-vendor risk after the June 12 export controls cut off Claude Fable 5/Mythos — 'relying on a single company's APIs for critical infrastructure... is a material vulnerability' — with Fugu Ultra benchmarking shoulder-to-shoulder with those now-banned models. The builder takeaway: multi-model orchestration is being productized as resilience against geopolitical and vendor lock-in, not just cost/quality routing.
