サカナ フグ

Sakana Fugu

Sakana AI's multi-agent platform that dynamically bundles multiple LLMs and serves them as a single API. Internally it directs (orchestrates) world-class specialist models so that it behaves as if it were a single model. It comes in two variants, Fugu and Fugu Ultra, matching or surpassing single frontier models across coding, reasoning, and science benchmarks. With an OpenAI-compatible API, it embodies an “AI sovereignty” philosophy that avoids dependence on any single vendor.
