- The process of building a coherent model persona from character archetypes and traits during training
- Stable, reidentifiable dispositional profiles that can be interpreted as characters with broadly coherent beliefs, values and traits
- The degree to which an LLM's generated responses consistently reflect an assigned persona
- Behavioural drift in multi-turn LLM interaction; documented in prior work for persona, identity, and instruction-following
- Keeping a model anchored to its intended persona during deployment, preventing drift to harmful behaviors
- Framework by Marks et al. proposing that models infer a context-appropriate persona for next-token prediction and post-training concentrates distribution around helpful assistant
- Key open question identified for future work on pretraining data as mechanism
