History YMMV / NovelAI

** Within the userbase themselves, the classic OldGuardVersusNewBlood, especially concerning text generator vs. image generator. The former was the reason most users subscribe, and with the name "Novel" AI, it was what appealed to them in the first place. The latter was developed later and it was at first praised for its SugarWiki/GeniusProgramming and becoming an easy money-maker due to the mass appeal for image generators, with its currency Anlas being able to be bought separately if the user does not have the infinite generation attempts from the Opus subscription tier. However, the split became clear when it was seen that there was more effort put into the image generator going by its more frequent update logs that the oldschool users only interested in storywriting felt alienated and began to stop subscribing. The absolute nadir was the 1.3 update to the furry model because it was ''yet another'' image generation update when the latest text generator model, Kayra, was released about ''half a year prior''. Text generator fans called it quits (with plenty of support to do this) and even blamed the image generator fans, while the latter defended by stating that this is the first major update for that specific model that finally allowed it to achieve the same SugarWiki/GeniusProgramming as the latest anime model and called out the impatient users.

* OnceOriginalNowCommon: When ''[=NovelAI=]'' was made as a reaction to the censorship in ''AI Dungeon 2'', people began looking forward to it, especially when the latter was hitting rock bottom in model quality no matter which model. People also began to use its API to complement it with other AI-based apps/games, which is helped by how relatively more powerful it was for something developed in-house. Everything being encrypted also won users over because of, again, scandals related to ''AI Dungeon 2'', this one where other people can read even the users' unpublished stories. However, more AI services sprang up with the same or even better quality, and even people are more appealed by [=ChatGPT=]'s instruct-style interaction (which ''[=NovelAI=]'' eventually applied but not so well). A few, like ''Spellbound Storytelling'', even encrypted requests and stories, do not have the same limitations as [=OpenAI=]-based services, and do not even require users to sign in to write stories. With how slow ''[=NovelAI=]'''s development is in both text and image department, long-time users have started complaining or even jumped ship while curious newcomers are alienated by the DifficultButAwesome tweaking just to get a good narrative or image when it can be easily done elsewhere. Heck, even ''AI Dungeon 2'' itself has caught up as of 2024, even with censorship.

* FandomRivalry: With ''VideoGame/AIDungeon2'', which, considering it was created by people who felt slighted by ''AI Dungeon''[='s=] filters and perceived privacy violations, is only natural.

* BrokenBase: The art generator. On one side of the spectrum, supporters cite it as a great example of SugarWiki/GeniusProgramming, being able to create artwork from lines of code and helping to immerse the stories they create, alongside producing visually stunning pieces (even if it takes several tries and careful wording). On the other hand, critics of it dislike people claiming generated pieces as their own work, and see art generated by neural networks as inherently conceptually too close to plagiarism for comfort due to the nature of it being trained on the work of existing artists. Others resent it [[SpotlightStealingSquad stealing the spotlight]], fearing that it will leave the text generation to be neglected in terms of updates -- and since text AI is in practice far harder to train than image AI, the image generator ''does'' get updated much more often, leading people to believe that the fears are not unfounded.

* GermansLoveDavidHasselhoff: For better or for worse, this model, especially the art generator which is made in Delaware is very popular in Japan, especially for the model trained on anime images. The text generator is no slouch there either, with one of the AI text models being specifically trained on Japanese-language works for this reason (though that is a work in progress), as well as a Japanese localization for the site being introduced in early 2023.

** The difficulty of getting characters in images to actually hold objects such as weapons in their hands -- let alone ''correctly'', with things such as characters holding swords by the blade being a common sight -- is notorious among the community.

* SpiritualSuccessor: ''Novel AI'' was created by people unsatisfied with changes that ''AI Dungeon'' underwent in 2021.

* FandomEnragingMisconception: No, the image generator does ''not'' trace, or copy/paste into a collage, or keep a database of images that it looks at and steals from, scour the Internet to swipe whatever you upload. That's simply not how the technology works, [[https://blog.novelai.net/the-magic-behind-novelaidiffusion-b4797e0d27b2?gi=93dec6162dc4 it's not even close to how it works]].

** Even though the image generator uses a modified version of the Stable Diffusion model, the base training data module for Stable Diffusion is not included, instead only having modules trained on images from Danbooru (for the anime modules) and [=e621=] (for the furry module). While the reason for this is the extensive and highly-specific tagging systems on those sites making training much easier, it still causes no end of frustration for people who want to create images that are neither anime nor furry.

On the other hand, from the opposing side, many dislike the art for being lazy while users call it their own work, and the fact that it is trained on the works of existing artists means that some see it as conceptually too close to plagiarism for comfort.

** Text in the Memory and Lorebook tends to leak into the main story verbatim if that is not specifically prepped against.

On the other hand, from the opposing side, many dislike the art for being lazy and the fact that it also uses data from other artists means that it's technically tracing from other people's artwork. One thing that does consistently almost never results in debates is that the art generator isn't likely to replace artists.
