Sakana AI launches Fugu to orchestrate swappable agents

On June 22, 2026, hardmaru announced the launch of Sakana Fugu. Fugu dynamically orchestrates leading models for complex tasks. hardmaru says a well-orchestrated pool of swappable agents can match restricted frontier models such as Fable and Mythos, and that Fugu routes around vendor restrictions through an entirely swappable agent pool.

hardmaru describes orchestration models as the next frontier beyond larger individual models. The Tokyo team’s vision and results are on the Fugu release page.
