<p><span style="font-size:14.0px"><p>LLMs have gained significant attention recently due to their remarkable capabilities. A similar, yet less explored field focuses on text-to-image (T2I) model architectures. Since a picture is worth more than a thousand words, one can assume that T2I models possess at least as many capabilities as text-to-text models (T2T). Therefore, it is important to subject these models to an "alignment" process. In T2T models, some neurones in the architecture are repurposed as safety neurones. To better understand the alignment process, the locations of safety neurones in both architectures should be compared.<br><br><br>Objective: The work aims to investigate the localisations of safety neurones in T2I models and compare them with T2T models. For this purpose, the proposed approaches for the localisation of safety neurones from T2T models will be adapted and implemented for T2I models. Finally, results regarding the localisation and significance of the neurones are analysed to highlight similarities and differences in the architectures.<br><br><br>Results: The results of this work aim to conceptualise the differences in model architectures for LLM security research. Since T2I models receive less attention, it is important to motivate further research on these models. For this purpose, a comprehensive comparison of different architectures and their associated safety neurones will be conducted as part of the work. The results are verified by a targeted deactivation of the identified neurones and then compared with randomly deactivated neurones.<br><br><br>What you do with us:</p>
