Image Generation Models
NovelAI Diffusion has 5 different models you can choose from when generating images.
Each of these models will behave differently, and should be selected according to what kinds of images you want to generate.
A description of the model you are currently selecting is displayed right above the prompt box. You can click it to select another model.
NovelAI Diffusion Anime V3
|
|
|
V3 is our latest anime image generation model. Available for all subscribing tiers.
Based on SDXL, along with some technology of our own, it offers much higher levels of coherence and knowledge compared to our older models.
Furthermore, V3 has a special feature of focusing more on the tags placed closer to the start of the prompt. Giving you more control over how your images are generated. More about that in the Tagging page
V3 also benefits from the higher base resolution of our V2 model (832x1216), and it also allows for free generations for Opus users as long as the usual conditions are met.\
NovelAI Diffusion Anime V2
|
|
|
Our V2 anime model is a step up from our first models.
It uses the same technologies as the V1 anime models, but benefits from updated training methodologies.
V2 also marks our increase in training resolution, meaning that it generates higher resolution images without the need of SMEA sampling.
When using the NovelAI Diffusion AnimeV2, and onward, the default portrait resolution will be 832x1216, increased from V1's 512x768.
Of course Opus subscribers will be able to generate 1024x1024, 832x1216, 1216x832, and similar resolution images for free, depending on the other settings.
NovelAI Diffusion Anime (Curated)
|
|
|
The NovelAI Diffusion Anime (Curated) model provides good baseline quality and predictable subject matter.
It is trained on a somewhat smaller training set of cleaner and more focused images.
Goose Tip: The (Curated) model is great for general use, and if you want to make extra sure you don't generate any sensitive images on accident. It's the safest choice when streaming video!
NovelAI Diffusion Anime (Full)
|
|
|
The NovelAI Diffusion Anime (Full) model has an expanded training set that allows for a wider variety of generations.
Compared to the (Curated) Model, it may have an easier time working with cruder concepts.
Goose Tip: Give the (Full) model a try if you're attempting to generate something specific and the (Curated) model doesn't seem able to do it!
NovelAI Diffusion Furry (Beta)
|
|
|
The NovelAI Diffusion Furry model makes it easy to create content themed around furries and anthropomorphic animals.
This model is still being developed, so it is labeled as (Beta).
Note that this model uses different Tags from the Anime models'.
Goose Tip: Give the Furry model a try and don't overlook the possibilities of this model, it can do so much more than furry art!
Note
Please keep in mind that the NovelAI Diffusion models will not produce the same results as the standard Stable Diffusion model, even with the same prompt and seed.
