Sakana AI releases Marlin, an 8-hour autonomous research agent at ¥150,000 per month

Sakana AI released Marlin, an autonomous agent that runs up to 8-hour research sessions, reconciles contradictions across web sources, and delivers reports of up to 100 pages with executive-summary slides — coming out of a 300-person closed beta in finance and consulting. The 'Virtual CSO' branding is marketing dressing; the engine is a reasoning method Sakana presented at NeurIPS 2025, and the per-session pricing marks the company's move from model APIs to managed research as a service.
