What happened?

The HarmProfile dataset has been launched via arXiv and consists of over 80,000 validated instances where advanced language models generated harmful content. The study covers 23 language models from 13 different model families, distributed across 15 areas of harm and 57 subcategories. Instead of merely recording whether an attack is successful, researchers analyze the actual text generated by the models when security safeguards fail.

Why it matters

Traditional evaluations often focus on whether a 'jailbreak' succeeds or fails, without closely examining what the model actually generates. By mapping content, severity, and variation in model failures, researchers can create a model-specific risk profile. This allows for a deeper understanding of how different architectures and training methods influence the nature of harmful output.

Who is affected?

The results are primarily relevant for AI researchers, security experts, and language model developers who need to improve their protection mechanisms. It also provides evaluators with tools to compare risks between different model families based on actual text output.

Impact on the EU

HarmProfile has been published as an open research resource and is available to researchers and authorities within the EU. The methodology of content-centric risk profiling can provide a concrete foundation for security assessments and compliance checks, although the dataset itself is not directly linked to specific EU legislation.

What else you should know

The researchers also noted significant variations in how models respond to the same types of misuse. Certain models exhibit very high levels of severity within specific subcategories, demonstrating that single general safety tests are insufficient to capture complex risk patterns.

Frequently asked questions

Quick answers about this story

Vad har hänt?
Forskare har publicerat datasetet HarmProfile som samlar över 80 000 validerade exempel på skadlig text från 23 ledande språkmodeller över 15 skadekategorier.
När hände det?
Forskningen publicerades som ett preprint-dokument på arXiv i augusti 2026.
Varför spelar det roll?
Det flyttar fokus från om en attack lyckas till att analysera det skadliga innehållet, dess svårighetsgrad och variation, vilket ger en mer detaljerad riskprofil för olika AI-modeller.
Hur många modeller ingår i studien?
Datasetet innehåller data från 23 olika avancerade språkmodeller fördelade på 13 modellfamiljer.
