Ever heard of the Omegaverse? It seems like OpenAI’s models are already deeply familiar. In case you’re not clued in, the Omegaverse is a niche subgenre of speculative erotic fanfiction that has developed its own complicated set of conventions and terminologies. But as Wired reports, fanfiction writers were startled when they realized that a writing assistant app called Sudowrite, which makes use of “several variants” of OpenAI’s GPT-3 — and, in our testing, the GPT-3-based ChatGPT — was suddenly spitting out incredibly specific Omegaverse-related smut. Per the report, the integration churned out a story that included something called “knotting,” an Omegaverse term that refers to a moment in which a male “Alpha’s” penis locks itself inside a vagina during sex. OpenAI has famously refused to say exactly what data it trains its large language models on, but given the damning evidence, the data clearly includes at least some Omegaverse-related works. It’s a fascinating glimpse into the vast amount of training data OpenAI’s models are trained on — and how the tech is starting to affect authors, whose work is being scraped by those models without being compensated. Though Omegaverse authors often aren’t looking to make money from their graphic labor of love, they understandably don’t think it’s right that someone else might — especially if they’re using AI chatbots like Sudowrite to generate fanfiction. And writers have been ringing the alarm bells for quite some time now. “This is particularly concerning as many for-profit AI writing programs… utilized GPT-3,” a Reddit user…ChatGPT Happy to Write Smut About Freakishly Obscure Sex Act
