Sakana Marlin is the first commercial product from Tokyo-based AI startup Sakana AI, launched on June 15, 2026. It is not a standalone large language model but an autonomous B2B research agent that orchestrates multiple frontier LLMs (including OpenAI o4-mini, Google Gemini 2.5 Pro, and DeepSeek-R1) via the company's proprietary AB-MCTS algorithm (Adaptive Branching Monte Carlo Tree Search, NeurIPS 2025 Spotlight). The agent operates without human intervention for up to eight hours, delivering strategy reports of up to 100 pages with executive summary slides. Its target audience is financial institutions, corporate strategy teams, consulting firms, and think tanks, where it is positioned as a "Virtual CSO" (Chief Strategy Officer).
