58AI Score

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.

Psychology has its own AI model now, and I think that’s a very big deal.

a model that reads the person, where language models read the text.

millionways has launched Thorsten-4, a Large Psychology Model

it scores each person in a conversation on 50 behavioral and psychological traits.

It learned from 35M+ words that trained psychologists hand-tagged from repeated interviews with 7,000+ people over four years, so its training data is observed human behavior instead of scraped internet text.

↳ 引用 @outofcords (Martin Cordsmeier): AI can write code, pass the bar exam and sound human.

It still can’t tell when you’re unsure, holding back or about to walk away.

Today we’re introducing Thorsten-4, a Large Psychology Model that predicts what people will do next.
