 Further Details, Social Impacts, Bias, and Limitations Please refer to our [paper](https://arxiv.org/abs/2212.10465). Cosmo is mostly trained on social chitchat. Therefore, we do not encourage having knowledge-intensive conversations (e.g., science, medical issues, law). Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. 2021](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. 2021](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.
