Sakana's Fugu Turns Model Choice Into Routing — Including Recursive Copies of Itself

Sakana AI's Fugu collapses the question of 'which model' into dynamic routing and delegation behind a single API, and can spawn recursive sub-agents.

Sakana AI's Fugu reframes a problem most developers currently solve by hand: which model should handle a given task. As @theneurondaily described it, Fugu 'turns model choice into routing and delegation behind one API,' abstracting away the model-selection decision entirely. Instead of a developer hard-coding when to call a cheap model versus an expensive one, Fugu makes that determination dynamically per request.
