About the Company

Sakana AI

Orchestrates multiple LLMs via API

Sakana AI builds AI foundation models and a multi-agent orchestration platform. Its flagship product, Sakana Fugu, runs as a single language-model interface that plans, delegates to, and combines outputs from a swappable pool of LLMs—including closed frontier models, open models, and its own instances—behind an OpenAI-compatible API. Fugu comes in two flavors: a low-latency everyday model and Fugu Ultra for tackling tough, multi-step tasks in software engineering, scientific research, and cybersecurity. The company differentiates itself by treating orchestration as a core capability to hedge against vendor lock-in and export-control shifts, using techniques like evolutionary model merging and agentic research systems. Sakana aims to provide reliable, flexible AI tooling for developers and enterprises through its API and tool integrations, while continuing to publish research on learned model orchestration.
