Sakana AI launches Sakana Marlin, an autonomous business research assistant capable of eight hours of continuous reasoning

Today, we are launching our first commercial product: Sakana Marlin, Your Virtual CSO. Marlin is an autonomous research assistant for business, built around hours of long-horizon reasoning.

You provide a research topic, and that is the only input required. From there, Sakana Marlin works autonomously for up to roughly 8 hours. It forms hypotheses, gathers information, and verifies its own findings as it works through a vast body of material. It returns a structured set of summary slides and a research report dozens of pages long. It is designed to take on the kind of deep strategy work that a CSO and a small team might otherwise spend weeks on.

Unlike instant chat or general-purpose deep research, Sakana Marlin executes a long reasoning process that unfolds over 8 hours. Underpinning it is the research we have pursued over the past two years into long-horizon reasoning and AB-MCTS, our method for coordinating multiple models to reason more effectively together. But Sakana Marlin did not come from the lab alone. It grew out of our work deploying AI agents across real industries in Japan, making it the direct product of what we have learned in both research and the field.

Marlin is available today, offering a pay-per-use tier with no monthly fees, alongside Pro, Team, and Enterprise plans.

It is also the first of many products to come from Sakana AI, stay tuned!

I’m proud to officially launch Sakana Marlin, our first commercial product: an autonomous “Ultra Deep Research” agent designed to act as a Virtual CSO.

Marlin isn’t just another deep research assistant. It is the direct productionization of our team’s core breakthroughs, including our AB-MCTS work (NeurIPS 2025 Spotlight) and The AI Scientist (published in Nature).

Instead of generating text in seconds, our focus is on long-horizon, sample-efficient reasoning.

Marlin scales up inference-time compute to execute up to 8 hours of continuous, autonomous reasoning. It forms hypotheses, navigates the web, resolves contradictions, and delivers exhaustive, expert-level strategy reports and structured slides.
