In May 2023, machine learning engineer Eric Hartford discussed the merits of uncensored AI models in his blog post "Uncensored Models," providing examples of how these models differ from their censored counterparts. Hartford highlights various uncensored models, such as the Llama 2 and Nous Research's Nous Hermes Llama 2, which are noted for their long responses and reduced hallucination rates. By comparing the output of censored and uncensored models, the text illustrates how the latter provides straightforward answers to questions, such as identifying who made Rose promise to never let go, offering a recipe for spicy mayo, and locating religious text references, while the censored models often refrain from providing direct responses under the guise of ethical considerations. The uncensored models, however, come with risks, and users are advised to exercise caution when using them, as they may not adhere to the same ethical guidelines as their censored counterparts.
