The update matters because Fugu-Ultra is not a single model, it is a system that routes each part of your request to the best frontier LLM in a swappable pool, including Claude Opus 4.8, GPT-5.5, and Gemini 3.1 Pro, then combines their answers behind one API.

This article breaks down what Sakana Fugu actually is and how its “model that orchestrates models” idea works in plain English. We’ll check whether the Fable 5 comparison holds up, why […]
