Important Caveats

1. Limited Direct Research: Much of the analysis of personality trait expression in LLMs comes from broader studies of model behavior rather than targeted research on character trait representation.

2. Evolving Field: Many observations are based on rapidly evolving technology, and newer models may exhibit different behaviors.

3. Proprietary Systems: Detailed technical information about commercial LLMs is often limited due to proprietary restrictions.
