Given how broad the capabilities of LLMs are and how varied their training data is, it is insufficient to identify
risks solely via *ex post facto* usage and analysis. Rather, as has been done for other LLMs, we performed
various kinds of *proactive* risk identification, colloquially called “r... | {

LLM. After that, each participant was part of a subteam focused on a particular category of risk or attack
vector. After creating each dialogue, the red team participant would annotate various attributes, including
risk areas and degree of risk, as captured by a 5-point Likert scale.

**Large Language Models.** The recent years have witnessed a substantial evolution in the field of LLMs.
