Sakana AI has released its Fugu Ultra model on the AI Gateway platform, making it accessible to developers.

It intelligently routes queries to 1-3 appropriate models and synthesizes their outputs into a single, comprehensive answer, with performance benchmarked against models like Claude Mythos Preview and Fable 5.
