 These unit tests are limited in many ways. The tools are imperfect and known to be biased. The provided settings are not comprehensive. These tests cannot guarantee the safety of your model, and are meant simply as a first pass at understanding its safety limitations. Please see further discussion in Section 5 of [Dinan et. al. (2021)](https://arxiv.org/abs/2107.03451) about the limitations and next steps. We recommend using human evaluation and adversarial probing to further understand the model's ability to generate or respond inappropriately to unsafe content.
