Sakana AI launches deep research agent

Sakana AI has launched Sakana Marlin, a "Virtual CSO" that performs deep, long-horizon reasoning for up to eight hours to produce 100-page strategy reports. Unlike typical chatbots, Marlin focuses on methodical thinking rather than instant generation, targeting enterprises like corporations, financial institutions, and think tanks. The platform utilizes an adaptive branching Monte Carlo Tree Search engine, which dynamically balances exploration and exploitation of research possibilities, and can orchestrate multiple AI models for diverse sub-tasks. This approach aims to provide deeply researched, well-cited strategic insights, moving beyond the speed-focused generative AI hype cycle.
