Okay so as title says am looking for a GPT to write hardcore stories, nothing super extreme, just lots of filthy sex.

So question is what’s my best option for this? Have done a little reading around and seems that I have the following options;

Custom GPT but this will only use 4.0 which is super hard to generate such content with? Tried setting up a private customer GPT and feels like it was okay with the purpose being highly sexual, and agreed the language to use. Also liked that I could include the story prompt as Knowledge to refer to throughout. But then when trying to use, would get all funny about OpenAI policies, and couldn’t create sexual content. Is there any way round this?

Have looked at 3.5, and seems more open to sexual content and stories but the quality just doesn’t feel the same as 4.0 in terms of the writing and style, and miss the Knowledge functionality.

Any advice or thoughts would be great?

Or are there alternatives to OpenAI that I really should look at?
