Open Models, Closed Minds? On Agents Capabilities in Mimicking Human Personalities through Open Large Language Models

Understand

The emergence of unveiling human-like behaviors in Large Language Models (LLMs) has led to a closer connection between NLP and human psychology.

• Scholars have been studying the inherent personalities exhibited by LLMs and attempting to incorporate human traits and behaviors into them.
• However, these efforts have primarily focused on commercially-licensed LLMs, neglecting the widespread use and notable advancements seen in Open LLMs.
• This work aims to address this gap by employing a set of 12 LLM Agents based on the most representative Open models and subject them to a series of assessments concerning the Myers-Briggs Type Indicator (MBTI) test and the Big Five Inventory (BFI) test.
