Sakana Fugu Wraps Multi-Agent Orchestration in a Single LLM API

Sakana Fugu exposes a multi-agent orchestration system as a single model via Chat Completions and Responses API endpoints, dynamically coordinating a pool of frontier models including GPT-5, Gemini 3.1 Pro, and Opus 4.8. It benchmarks against those three models as baselines and ships with a one-line Codex integration for Ubuntu and macOS. The coordinator layer is retrained as new frontier models are released.
