Sakana AI ships Fugu beta

Sakana AI opened early beta applications on April 24 for Sakana Fugu, a commercial system that coordinates multiple AI models behind one application programming interface. (sakana.ai) The Tokyo-based company said Fugu is its “flagship international commercial AI product” and will be offered first through an API that has already been used internally by Sakana researchers and engineers. (sakana.ai 1) (sakana.ai 2) A multi-agent system works like a dispatcher: instead of sending every task to one model, it assigns parts of the job to different models and combines the results. Sakana said Fugu learns those coordination patterns rather than relying on fixed hand-written workflows. (sakana.ai) Sakana said that setup is meant to spare developers from juggling separate API keys and manually choosing among model providers for each task. The company said Fugu supports standard OpenAI-format endpoints so teams already using GPT-, Gemini-, or Claude-style API workflows can swap it in with smaller changes. (sakana.ai) The company’s benchmark table lists two versions, Fugu Mini and Fugu Ultra, and shows Fugu Ultra at 95.1 on GPQAD, ahead of Gemini 3.1 High at 94.4, GPT 5.4 High at 90.9, Opus 4.6 Max at 92.7, and Fugu Mini at 92.4. (sakana.ai) Sakana said Fugu is the product version of research it has been publishing on collective intelligence, including systems that combine models through tree search, automate scientific research, and use evolutionary search to improve programs. The company tied Fugu specifically to its ICLR 2026 papers “Trinity” and “Conductor.” (sakana.ai) The release also extends Sakana’s shift from research lab to software vendor. In November 2025, the company said it had raised 32 billion yen, about $200 million, in a Series B while building enterprise AI products for large Japanese customers. (sakana.ai) Sakana was founded in Tokyo in 2023 by Chief Executive David Ha, Chief Technology Officer Llion Jones, and Chief Operating Officer Ren Ito. Fugu is now the company’s latest beta product after its Marlin research assistant beta opened earlier in April 2026. (sakana.ai 1) (sakana.ai 2) For now, Sakana is not broadly releasing Fugu; it is taking applications from early beta testers. The pitch is simple: one endpoint, multiple models, and Sakana handling the routing. (sakana.ai)
