# Sakana AI Source: https://sakana.ai/marlin-release/ ## Sakana AI Launches Its First Commercial Product, Sakana Marlin (https://sakana.ai/marlin-release/) June 15, 2026*An autonomous research assistant that completes strategic research in a matter of hours.* --- *(English Announcement Below\.) (https://sakana.ai/marlin-release/#English)* Sakana AI today began offering **Sakana Marlin**, our first commercial product, an autonomous research assistant for business. Simply specify a research topic, and it will work autonomously for up to approximately eight hours, generating structured summary slides and a detailed research report of dozens of pages. **👉 Product page: sakana\.ai/marlin (https://sakana.ai/marlin/)** ## **Sakana Marlin, Your Virtual CSO.** Sakana Marlin is an autonomous research assistant built on our proprietary long-horizon reasoning technology. It is designed for AI to take on the kind of heavyweight strategic research that a Chief Strategy Officer (CSO) would spend weeks conducting with a small team. When you first set a research topic, Sakana Marlin refines the investigation’s objectives through dialogue. Once the direction is set, the AI works autonomously without human intervention, repeatedly forming hypotheses, gathering information, and verifying its findings, digging into key points from vast amounts of information. It goes beyond mere summarization, organizing the causal relationships in complex business environments into structured "strategic options" that executives can immediately consider. By having Sakana Marlin handle exhaustive research and structuring, humans can focus on the highest-value work: decision-making itself. **Using it is as simple as entering a research topic.** Once you give it a topic, Marlin completes the research and outputs both summary slides and a detailed report. *Example output: detailed report (top) / summary slides (bottom)*It can be used by a wide range of professionals who regularly conduct research, including corporate strategy and business planning departments at financial institutions and operating companies, consulting firms, think tanks, and research agencies. It is available for same-day self-service use, with plans ranging from a monthly free Pay-per-Use tier to Pro, Team, and Enterprise plans. For details on pricing and purchasing, please see the product page (https://sakana.ai/marlin/). ## **Development Background: Integration of Research and Implementation** Sakana Marlin was developed by integrating the research insights and implementation experience that Sakana AI has accumulated over the years. In the research domain, we have released the "AI Scientist" that automates the process of scientific discovery, "AB-MCTS" that coordinates multiple models to enhance reasoning ability, and "ALE-Agent" that automates algorithm engineering. At the same time, through practical applications such as implementing AI agents in various domestic industries, we have been building mechanisms for agents to autonomously execute advanced workflows. These long-horizon reasoning and multi-model optimal control technologies have culminated in Sakana Marlin. Technical details are available in our beta release blog (https://sakana.ai/marlin-beta/).

Approximately 300 professionals from diverse industries including financial institutions, operating companies, consulting firms, and think tanks participated, using it in real tasks such as strategy formulation, market research, risk analysis, and competitive analysis. While we received many evaluations that it was "more practical at digging deeper into information compared to existing chat-based research tools," we also received specific requests regarding output formats and report structure. For the official release, we have strengthened research quality, output format, and stability for long-duration tasks based on this feedback. ## **Conclusion** We express our deep respect to the AI community that develops and releases excellent foundation models. Our achievements stand on top of these preceding technological foundations and the open ecosystem. We also thank all our beta testers who provided candid feedback. The official release of Sakana Marlin is an important step for us in commercial product deployment. Going forward, we will continue to incorporate research results in multi-model optimal control technology and agent technology, and proceed with development toward providing diverse AI solutions that go beyond chat services. We are looking for people to help shape the future of AI in Japan together with Sakana AI. Please see our careers page (https://sakana.ai/careers/).

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\. **👉 TrySakana Marlin (https://sakana.ai/marlin/)\! \(sakana\.ai/marlin (https://sakana.ai/marlin/)\)** *Note: This service is subject to regional availability restrictions\. For more information, please see our Terms of Service\.* ## **Sakana Marlin, Your Virtual CSO\.** Sakana Marlin is designed to take on the kind of substantial strategy research that a Chief Strategy Officer \(CSO\) and a small team might otherwise spend weeks on\. The user begins by setting a research topic, and Sakana Marlin sharpens the direction of the investigation through a brief exchange with the user\. Once the course is set, it works without further human input: it repeatedly forms hypotheses, gathers information, and verifies its findings on its own, digging through a vast body of material to surface the questions that matter\. It does more than summarize\. Marlin maps the causal relationships at work in complex business environments and organizes them into structured strategic options\. By taking on the work of comprehensive research and structuring, Marlin frees people to concentrate on the highest-value work of all: the decisions themselves\. **Using Marlin is simple: you enter a research topic\.**Once you set the theme, Marlin carries the research through to completion and delivers both summary slides and a detailed report\. *Example output: detailed report \(top\) and summary slides \(bottom\)\.*Marlin is built for the wide range of professionals who work with research every day—corporate strategy and business-planning teams at financial institutions and operating companies, consulting firms, think tanks, and research houses\. We have made Marlin available as a pay-per-use tier to monthly Pro, Team, and Enterprise-tier plans\. For pricing and purchasing details, please see theproduct page (https://sakana.ai/marlin/)\. ## **The Background: Bringing Research and Deployment Together** Sakana Marlin brings together the research insight and the deployment experience that Sakana AI has accumulated over the years\. On the research side, we have published work such asThe AI Scientist (https://sakana.ai/ai-scientist-nature/), which automates the process of scientific discovery;AB-MCTS (https://sakana.ai/ab-mcts/), which coordinates multiple models to strengthen their reasoning; andALE-Agent (https://sakana.ai/ahc058/), which automates algorithm engineering\. In parallel, through real-world deployment—including implementing AI agents across a range of industries in Japan—we have been building the machinery for agents to execute sophisticated workflows on their own\. These technologies for long-horizon reasoning and the optimal control of multiple models are what came together in Sakana Marlin\. Technical details are available in ourbeta-release blog post (https://sakana.ai/marlin-beta/)\. [](https://sakana.ai/ai-scientist-nature-jp/)*Sakana Marlin’s advanced research capabilities utilize several techniques from Sakana AI’s research efforts, including AB-MCTS \(NeurIPS 2025 Spotlight (https://arxiv.org/abs/2503.04412)\) and The AI Scientist \(Published inNature (https://www.nature.com/articles/s41586-026-10265-5)\)\.* ## **Working With Around 300 Beta Testers** Sakana Marlin was refined to a level fit for real-world use through a closed beta that began in April 2026\. Around 300 professionals from a range of industries—financial institutions, operating companies, consulting firms, and think tanks—took part, putting Marlin to work on real tasks such as strategy formulation, market research, risk analysis, and competitive analysis\. Many told us that Marlin was more practical at digging deeply into information than the chat-based research tools they had used before, while also sharing specific requests around output formats and report structure\. For the official release, we have drawn on this feedback to strengthen research quality, output formatting, and the stability of long-running tasks\. ## **Looking Ahead** We are grateful to the AI community whose open foundation models our work builds on, and to our beta testers for their candid feedback\. Sakana Marlin is an important step in our commercial rollout\. It joinsSakana Chat (https://chat.sakana.ai/)in a growing lineup, with more on the way, includingwork that coordinates frontier models (https://sakana.ai/fugu-beta/)to push performance further\. Each grows from the same conviction that runs through our research: that the most capable AI comes not from a single model, but from systems that reason over time and work together\. We will keep building in this direction, toward AI solutions that reach well beyond chat\. We are looking for people to help shape the future of AI in Japan together with Sakana AI\.
