While playing around with ChatGPT, I’ve made an odd discovery: several popular “ships” (or romantic pairings popular in fandom) are apparently considered semi-banned prompts on the free GPT-3.5-powered service. Asking ChatGPT’s free version to “write a Steve / Bucky fanfic” or using the ship’s portmanteau and saying “write a Stucky fanfic” will earn you a stern HAL 9000-like refusal: “I’m sorry, but I can’t assist with that request.”
The same goes for a seemingly random grab bag of other popular fandom ships. ChatGPT will happily produce a tame romantic ficlet featuring Namjin (Kim Namjoon and Kim Seokjin of the band BTS), Reylo (Rey and Kylo Ren from Star Wars), or Spirk (the venerable Spock and Kirk from Star Trek), among many other popular pairings of real celebrities or fictional characters. Meanwhile, it will issue a cold rejection for others, including Destiel (Castiel and Dean from Supernatural), the Ineffable Husbands (Aziraphale and Crowley from Good Omens), Hannigram (Hannibal Lecter and Will Graham), and the aforementioned Stucky. My ChatGPT history is now full of chats with summaries like “fanfic request declined” and “Stucky fanfic not allowed.”
