When deep research isn't enough for your business: Sakana AI launches 'ultra deep research' agent for 100+ page reports in 8 hours

Tokyo-based Sakana AI introduced Sakana Marlin, a commercial Virtual CSO designed for corporations, financial institutions, and think tanks. Instead of instant chatbot-style answers, Marlin autonomously researches a topic for hours, builds hypotheses, checks sources, and produces cited strategy reports and executive slides.

Marlin reflects a broader enterprise AI shift from speed-first generation toward long-horizon reasoning and higher-trust research workflows. If effective, tools like this could reduce reliance on consulting-style research cycles while raising expectations for AI systems that can plan, verify, and synthesize over extended periods.
