Sakana AI 推出商用 AB-MCTS 技術的企業級代理 Sakana Marlin，可自動生成多達百頁研究報告與簡報

Tokyo-based Sakana AI shipped its first commercial product ‘Sakana Marlin’ this week. Sakana team positions it as a Virtual CSO (Chief Strategy Officer). It is a B2B autonomous research agent built for enterprises. Marlin does not answer in seconds like a chatbot. You give it one research topic. It then runs autonomously for up to about eight hours. Each run returns a long report plus a presentation slide deck. Sakana says a single session issues hundreds to thousands of LLM queries. What is Sakana Marlin Marlin is an enterprise research agent, not a chat assistant. You give it one topic or question. It then plans hypotheses, browses sources, and verifies findings on its own. It compresses weeks of strategy work into hours. The deliverable is structured for decision-makers. The Japanese announcement describes reports of dozens of pages. The English announcement cites reports of up to roughly 100 pages. At a press hands-on, reports ran 60–100 pages and cited 60–80 sources. Each report includes a main body, references, and appendices. Presentation slides are generated using image-generation AI. Sakana team refined Marlin through a closed beta in April 2026. Around 300 professionals tested it on real tasks during that beta. Those tasks spanned strategy formulation, market research, risk analysis, and competitive analysis. Sakana has also partnered with MUFG and taken strategic investment from Citigroup.
