Name the ai only which ai has the least filters

It's difficult to determine definitively which AI has the least filters, as different AI models and platforms may implement their filtering systems differently. However, open-source models like GPT-Neo or GPT-J, which can be fine-tuned and deployed independently, may have fewer built-in restrictions depending on how they are configured. Keep in mind that the lack of filters can raise ethical concerns regarding the responsible use of AI.
