Large Psychology Model

Millionways AI released Thorsten-4, a large psychology model trained on 35M+ hand-tagged words from four years of repeated interviews with 7,000+ people to infer motives and decision styles behind language. A hedge fund now runs a dedicated $50M portfolio on its signals, and enterprises can plug it into existing agent tooling.

Millionways AI released Thorsten-4, billed as a Large Psychology Model trained on 15+ years of psychology research, repeated interviews with 7,000+ people by 50+ psychologists over four years, and 35M+ hand-tagged words. It claims 90% validated accuracy in predicting motives, decision styles and likely reactions, targeting agent use cases such as sales calls, interviews and customer service where LLMs misread human hesitation.

Millionways has launched Thorsten-4, a Large Psychology Model that scores each person in a conversation across 50 behavioral and psychological traits. Its training data comes from over 35 million words hand-tagged by trained psychologists from repeated interviews with more than 7,000 people over four years, rather than scraped web text. The model aims to move from reading text to reading people, predicting hesitation, withholding and disengagement.
