arXiv:2606.10080v1 Announce Type: new Abstract: Generative models have shown remarkable progress in a variety of domains such as protein design, but such power enables the opaque generation of hazardous proteins. In this work, we introduce VFUSE (Virulent Feature Understanding with Sparse autoEncoders), a mechanistic interpretability approach that trains SAEs on diffusion-transformer activations to audit protein models for hazard-aware features. We apply VFUSE to RoseTTAFold3 and RFDiffusion3, popular open-weight models for protein folding and synthesis. We find that for certain blocks, linear
The rapid advancement in generative AI for protein design necessitates concurrent development of ethical auditing tools to mitigate potential misuse, especially with models becoming more accessible.
This work directly addresses the dual-use concerns of advanced synthetic biology, providing a critical mechanism for identifying and understanding hazardous features in AI-designed proteins before they can be widely deployed.
The ability to audit generative protein models for 'virulent features' introduces a new layer of oversight and safety, potentially influencing future regulatory frameworks and development practices in synthetic biology.

VFUSE provides a method to scrutinize generative protein models for the presence of harmful characteristics.
This scrutiny could lead to the development of industry standards and regulations for 'safe' generative protein design.
The existence of such auditing tools may spur a 'red team-blue team' dynamic in synthetic biology, where capabilities for both generation and detection of hazardous biological materials rapidly advance.
