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 AI startup Sakana AI launched its first commercial product, Sakana Marlin, an autonomous B2B research agent designed for deep, long-horizon reasoning. The service, which had been in beta since April, was commercialized and aims to produce reports of over 100 pages in 8 hours, positioning itself as a "Virtual CSO" distinct from instant-response chatbots.
