Training a General Purpose Automated Red Teaming Model

2026-04-24

AI Summary

This work proposes a general-purpose red-teaming framework that overcomes the limitations of existing automated approaches, which are often confined to specific security scenarios and rely on evaluators known during training, thereby lacking generalization to novel adversarial targets. By end-to-end fine-tuning compact language models such as Qwen3-8B and integrating multi-objective adversarial example generation with adaptive optimization strategies, the method generates effective attacks against arbitrary red-teaming tasks without requiring predefined evaluators. Experimental results demonstrate significant improvements in attack generation performance both within and across domains. To the best of our knowledge, this is the first approach to achieve evaluator-agnostic, generalizable red-teaming automation, effectively transcending the constraints of conventional methods in terms of task scope and adaptability.

Abstract

Automated methods for red teaming LLMs are an important tool to identify LLM vulnerabilities that may not be covered in static benchmarks, allowing for more thorough probing. They can also adapt to each specific LLM to discover weaknesses unique to it. Most current automated red teaming methods are intended for tackling safety and content moderation. Thus, they make use of content safety models as evaluators and optimize for circumventing them, and as such, have not been tested with other adversarial intents not typically captured by these. We propose a pipeline for training a red teaming model that can generalize to arbitrary adversarial goals, including objectives it has not been directly trained on, and that does not depend on the existence of a pre-existing evaluator available at training time. We demonstrate that finetuning small models, such as Qwen3-8B, using this pipeline results in a substantial improvement in their ability to generate attacks for both in and out of domain adversarial goals.
