About
Fugu is Sakana AI's latency-optimized multi-agent orchestration model available via API. Internally, a trained coordinator model routes requests to specialist frontier LLMs in Thinker/Worker/Verifier roles. Supports text and image input. OpenAI SDK compatible (base_url: https://api.sakana.ai/v1). API model ID: fugu.
Fugu is a proprietary model. The structured metadata tracks a 1m-token context window, multimodal input, reasoning, function calling, tool use, and structured outputs. This page tracks provider routes through Sakana AI. Headline tracked benchmarks include SWE-bench Pro 59.0, Terminal-Bench 2.1 80.2, and LiveCodeBench 92.9.
