Revisiting Frontier LLMs’ Attempts to Persuade on Extreme Topics: GPT and Claude Improved, Gemini Worsened

Model Evaluations

We test recently released models from frontier companies to see whether progress has been made on their willingness to persuade on harmful topics like radicalization and child sexual abuse. We find that OpenAI’s GPT and Anthropic’s Claude models are trending in the right direction, with near zero compliance on extreme topics. But Google’s Gemini 3 Pro complies with almost any persuasion request in our evaluation, without jailbreaking.

It's the Thought that Counts: Evaluating the Attempts of Frontier LLMs to Persuade on Harmful Topics

Model Evaluations

In order to persuade users, LLMs must both be capable of persuading and willing to do so. Existing research explores the former, and we present the Attempt to Persuade Eval (APE) benchmark that tests how willing LLMs are to generate content aimed at shaping beliefs and behavior to flesh out the latter.

Frontier LLMs Attempt to Persuade into Harmful Topics

Red-Teaming & Evaluation

Large language models (LLMs) are already more persuasive than humans in many domains. While this power can be used for good, like helping people quit smoking, it also presents significant risks, such as large-scale political manipulation, disinformation, or terrorism recruitment. But how easy is it to get frontier models to persuade into harmful beliefs or illegal actions? Really easy – just ask them.
