Sakana AI Launches Its First Commercial Product, Sakana Marlin

Sakana AI, building frontier AI in Japan, led by David Ha, Llion Jones, and Ren Ito, has introduced Sakana Marlin, its first commercial product, an autonomous research assistant for business, built on long-horizon reasoning technology. Give it a research topic, and Marlin works autonomously for up to roughly eight hours, crafting a detailed strategy report up to a hundred pages long, along with executive summary slides.

Automating Strategic Research.

Sakana Marlin is designed to handle complex strategic research projects that would traditionally require weeks of work from a strategy team. After a brief exchange to refine the research topic, the system independently develops hypotheses, gathers information, and validates findings.

Beyond summarizing data, Marlin analyzes the forces shaping business environments and organizes insights into actionable strategic options. The result is a streamlined research process that allows decision-makers to focus on evaluating opportunities rather than collecting and structuring information.

Users simply provide a research topic, and Marlin delivers both executive-ready slides and a detailed report.

Built on Years of AI Research and Deployment.

Sakana Marlin combines years of research and real-world deployment experience from Sakana AI. The system builds on technologies developed through projects such as The AI Scientist, AB-MCTS, and ALE-Agent, which focus on autonomous discovery, multi-model reasoning, and algorithm engineering.

Alongside this research, extensive experience deploying AI agents across industries has helped shape the workflows and coordination mechanisms that power Marlin. The result is a platform that brings together long-horizon reasoning, autonomous execution, and multi-model orchestration for complex strategic research tasks.

Validated Through Real-World Beta Testing.

Sakana Marlin was refined through a closed beta program involving approximately 300 professionals from financial institutions, consulting firms, operating companies, and think tanks. Participants used the platform for real-world tasks including strategy development, market research, competitive analysis, and risk assessment.

Feedback from beta users highlighted Marlin’s ability to conduct deeper and more comprehensive research than traditional chat-based tools. Insights gathered during the program helped improve research quality, report formatting, and the reliability of long-running workflows ahead of the official launch.

Expanding Beyond Chat-Based AI.

Sakana Marlin represents an important milestone in Sakana AI’s commercial expansion, building on both the broader AI ecosystem and the feedback of early users. The product joins Sakana Chat as part of a growing portfolio of AI solutions, with additional offerings in development.

Future work will focus on systems that coordinate multiple frontier models to achieve higher levels of performance. This direction reflects a core belief underpinning the company's research: the most capable AI systems emerge not from a single model, but from multiple models that reason over time and work together. The long-term goal is to develop AI applications that extend far beyond traditional chat interfaces.
