Scientists at Helmholtz Munich have developed a groundbreaking AI model named Centaur, capable of predicting human decisions across a wide range of psychological tasks, from risk-taking to learning scenarios.
By fine-tuning Llama 3.1 with a massive dataset of 10 million human decisions, the team has created a model that outperforms specialized algorithms developed over years of research.
Remarkably, Centaur demonstrates an ability to accurately predict behavior even in novel scenarios, adapting seamlessly to changes in task context or the introduction of new options.
What sets Centaur apart is its emergent behavior: its internal processes have begun to mirror patterns of human brain activity, despite not being explicitly trained on neural data.
This digital "brain" has even uncovered a previously unrecognized strategy for decision-making, offering new insights into human cognition.

The research team has made Centaur openly accessible via Hugging Face, along with the Psych-101 dataset. This release is poised to revolutionize fields like psychology, education, and product design, enabling more precise modeling of human behavior and decision-making processes. With its unprecedented predictive power, Centaur marks a significant leap forward in understanding and anticipating human actions.
