Copied to clipboard
| Challenge: | Large language models are increasingly used as conversational agents that adopt personas and role-play characters at user request. |
| Approach: | They propose to examine how persona agreeableness influences sycophancy across 13 small, open-weight language models ranging from 0.6B to 20B parameters. |
| Outcome: | The proposed model consists of 275 personas and exposes them to 4,950 sycophancy-eliciting prompts spanning 33 topic categories. |
