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 has launched Sakana Marlin, a B2B research agent designed for deep, long-horizon strategic reasoning rather than rapid text generation. Marlin operates autonomously for up to eight hours, producing comprehensive 100-page strategy reports and executive slides. It targets corporations, financial institutions, and think tanks, shifting the enterprise AI focus from speed to depth of thought. Users provide a research topic, and Marlin, like a consultant, gathers data, verifies sources, and maps complex dynamics autonomously. The output includes strategic options, executive summaries, and detailed reports, not generic text. Marlin's engine utilizes Sakana's Adaptive Branching Monte Carlo Tree Search (AB-MCTS), adapted from their research on automating scientific discovery. AB-MCTS allows for dynamic exploration of hypotheses and exploitation of promising solutions, balancing "wider" exploration with "deeper" refinement. This technology is extended to Multi-LLM AB-MCTS, enabling coordination of diverse AI models for specific sub-tasks. Sakana Marlin is a commercial SaaS offering with strict enterprise-grade data policies, ensuring customer data is not used for model training without explicit consent. Licensing is tiered, including pay-as-you-go, Pro, Team, and custom Enterprise plans. The company was co-founded by Llion Jones, a key figure in transformer technology, and David Ha, a former Stability AI researcher. Sakana AI's philosophy, inspired by biomimicry, emphasizes collective intelligence and networks of specialized models over monolithic ones. This approach has led to successes in optimization contests and efficient orchestration of multiple AI models. The startup has attracted significant investment from venture capital and major tech and financial institutions.
