RT by @hardmaru: ベースモデルに依存しないオーケストレーションに向けて ブログ：https://sakana.ai/fugu-gemma4/ Sakana…

TL;DR - Sakana AI announced that Fugu, its multi-agent orchestration product exposed as a single foundation-model endpoint, now has a "conductor" model retrained on the open Gemma 4 base, aiming for base-model-independent orchestration. It matters because it decouples routing intelligence from any single vendor's model, a step toward sovereign, swappable agent stacks.

• Fugu is a two-layer system: a swappable "model pool" that performs the actual work, and a "conductor model" that decides task allocation across those models.
• Clients send one request to a single endpoint; Fugu decides how to process it and dispatches to appropriate models, reportedly exceeding single-model performance and cost-performance.
• The model pool was designed to be interchangeable from the start; this release extends interchangeability to the conductor itself, now trained on Gemma 4.
• On Sakana's internal evaluation set, the Gemma 4-based conductor matched prior performance while reducing cost; next steps target conductors built on Sakana's own in-house models for sovereignty requirements. No public benchmark numbers were given.
