Sakana AI Commercializes AB-MCTS in Sakana Marlin: An Enterprise Agent That Generates Up to 100-Page Research Reports with Slides
Sakana AI, a Tokyo-based artificial intelligence startup, shipped its first commercial product, Sakana Marlin, in June 2026. The company positions Marlin as a Virtual CSO (Chief Strategy Officer)—a B2B autonomous research agent designed specifically for enterprise use cases.
Unlike a chatbot that responds in seconds, Marlin operates on a fundamentally different tempo. Users provide a single research topic, and the agent runs autonomously for up to eight hours. Each run produces a comprehensive output, including research reports that can span up to 100 pages, complete with presentation slides.
## Under the Hood: AB-MCTS
Marlin is powered by AB-MCTS (Attention-Based Monte Carlo Tree Search), a proprietary algorithm that Sakana AI has now commercialized. AB-MCTS combines the structured exploration of Monte Carlo tree search with attention mechanisms, enabling the agent to navigate complex research spaces efficiently. This architecture allows Marlin to break down broad topics into subtasks, gather and synthesize information from multiple sources, and iteratively refine its outputs without human intervention.
## Enterprise Impact
The product targets organizations that need deep, structured research at scale—strategic planning, competitive analysis, market intelligence, and long-form content generation. By automating the research pipeline, Marlin aims to reduce the time and cost associated with traditional consulting or in-house research teams.
## 2026 Context
Marlin enters a market increasingly dominated by specialized AI agents, not general-purpose chatbots. Enterprises in 2026 are prioritizing agents that can handle complex, multi-hour workflows with minimal oversight. Sakana AI's move reflects a broader industry shift toward “deep reasoning” agents that combine planning, search, and generation to deliver production-ready assets.
## Availability and Future Plans
Sakana Marlin is available now as a cloud-based service. The company has not disclosed pricing details but indicates it will be subscription-based, tailored to research volume and report length. Future updates are expected to include integration with enterprise data sources and support for multi-modal outputs beyond text and slides.
