Sakana AI Marlin, released on June 15, 2026, is an autonomous research agent designed to support enterprises in making high-level strategic decisions. This tool aims to function as a Virtual Chief Strategy Officer and technically addresses the limitations of existing conversational models, which often only provide superficial summaries or short answers within a limited timeframe. When a user inputs a complex business topic or technical exploration task, Marlin autonomously continues its exploration loop, dynamically scaling its inference-time compute resources in the background for up to 8 hours. Its core technology incorporates an Adaptive Branching Monte Carlo Tree Search architecture, which allows it to independently evaluate the various logical branches that emerge during research, correct errors, and explore the optimal path leading to the final output. While existing search-based AI tools excel at quickly compiling web search results, they have significant limitations in analyzing the inter-contradictions or causal relationships within large volumes of data. Marlin goes beyond the capabilities of conventional AI chatbots, which simply summarize information in a piecemeal fashion based on short-term memory. Instead, Marlin functions more like an experienced senior advisor who spends days cross-referencing specialized books and global reports in a library to produce high-quality, in-depth articles. By moving beyond a linear search flow, Marlin independently reviews multiple alternative hypotheses and dynamically assigns appropriate large language models to each branch, allowing it to self-monitor for logical flaws. Through this orchestration process, it presents a comprehensive and in-depth research report and presentation slides, spanning dozens of pages, with clear citations of the original sources. In complex, technology-driven business environments, including the biotechnology and fine chemicals sectors, Marlin can deliver disruptive results. For example, Marlin can be deployed in a medium- to long-term project to comprehensively review global patent disputes related to a specific gene-editing technology and the latest rulings from courts in various countries, identifying potential alternative technologies. Operating in the background for 8 hours and meticulously comparing academic journals and documents from regulatory agencies in different countries, Marlin structures the complex web of legal risks and technical options into a set of strategic options. By reducing the time required for human research teams to gather and analyze information and refine presentation slides from weeks to just a few hours, executives and senior researchers can free themselves from the inefficiencies of the preliminary information-gathering process and focus their efforts entirely on making final strategic decisions and determining whether to proceed with the development of new pipelines.

Analysis of the Feasibility of Introducing New Drugs and Global Patent Trends: To analyze the global patent dispute landscape and next-generation workaround technology pipelines in the field of Targeted Protein Degraders, the system was configured to analyze a vast range of sources, including PubMed and ClinicalTrials.gov, using AB-MCTS for 8 hours. As a result, a quantitative report of over 100 pages and a slide deck for decision-making were obtained, significantly reducing the review period from 3 weeks to 1 day.
