When it comes to generating NSFW AI image generator content or uncensored images with AI, the starting point is always a base model — a large, general-purpose NSFW AI image generator model trained on a wide range of data. These models aren’t uncensored by default, but they form the foundation that creators and communities fine-tune into more specialized, uncensored NSFW AI image generator versions.
The most important base models in this space are:
As the demand for artistic expression grows, the NSFW AI image generator models have gained immense popularity, leading to a diverse ecosystem of NSFW AI image generator tools.
Stable Diffusion 1.5 (SD 1.5) – The classic and most widely adopted base model. Known for speed, low VRAM usage, and an enormous ecosystem of tools and checkpoints. It generates images in 512×512 resolution.
Stable Diffusion XL (SDXL) – A more advanced version of SD with better prompt understanding, detail, and realism — though it’s heavier to run. It generates images in 1024×1024 resolution.
Pony Diffusion – Originally trained on stylized artwork (especially furry and pony styles), it’s become a foundation for some niche but very expressive fine-tunes. It generates images in 1024×1024 resolution.
Flux 1 (Flux.1): A newer open-weight model family designed for high-quality generation and flexibility. With a limited license.
Note: There are other versions of Stable Diffusion, but we don't recommend them.
How to Pick Between These Base Models
With several open-source base models available, the big question is: which one should you build on for NSFW or uncensored image generation?
Each model has different strengths, and the right choice depends on your style goals, hardware, and how much you plan to fine-tune. Here’s how to decide:
1. Hardware Requirements for NSFW Ai image generator models
- SD 1.5 is the most lightweight and also the oldest — it runs comfortably on 4–6GB VRAM and is perfect for mid-range GPUs or cloud deployments. So if you don’t have a powerful GPU this might be your only option(Although we have a new article coming up that will teach you how to rent powerful GPU’s for cheap, so stay tuned).
- SDXL and Flux 1.S require more power, typically 12–16GB+ VRAM. They offer higher quality but aren’t as portable.
- Pony Diffusion is based on SD 1.5, so it shares the same low hardware requirements — great for accessible stylized generation.
2. Style vs. Realism
- SD 1.5 leans toward stylized or “AI art” vibes — it’s great for anime, illustration, fantasy, and more playful NSFW themes. But lacks strength in realism.
- SDXL and Flux 1.S produce more realistic images, with better lighting, anatomy, and photographic depth.
- Pony Diffusion is highly stylized by design — ideal for furry, pony, and anthropomorphic art. It’s unmatched in that niche but not suited for realism. However, several fine-tunes of Pony have pushed it surprisingly far into realism. Pony is generally great at producing really detailed images that follow the prompt, but it has it’s limitations.
Which one would we pick?
Here’s a simple way to decide:
- If your hardware is limited, stick with an SD 1.5-based model. It’s lightweight, easy to run, and has the most available fine-tunes for NSFW content.
- If you have a decent GPU setup (12GB+ VRAM) and want a powerful, general-purpose model that can generate high-quality images with good variety — especially for faces and realism — go with an SDXL-based model.
- If your focus is on people, furry, or anime-style content, Pony Diffusion is your best bet. While the base model is stylized, community fine-tunes have pushed it far into realistic and high-quality territory for NSFW generation.
- We don’t recommend Flux 1 for NSFW content — yet. Despite its potential and impressive raw image quality (often better than SDXL or Pony), its restrictive license and lack of community fine-tunes limit its usefulness. It also hasn’t proven itself in NSFW-specific generation the way the other models have.
Here are examples images to help you decide:
Let’s analyze
SD1.5 – is clearly less detailed, it looks most AI of the bunch. Original image was generated into 512×512 resolution, later it was upscaled to 1024×1024 thanks to hires.fix.
SDXL – Looks really natural and realistic, hair is really detailed. Original image was generated in 1024×1024 resolution. This upgraded image quality comes with certain downsides, namely much longer image generation time and higher VRAM use.
Pony – Looks most detailed, but it feels like Ai model added too much detailing. Just like with SDXL this image was also generated in 1024×1024. Pony has another issue, faces look kinda similar, there is some variability but once you get used to it you will notice clear Pony look of the faces.
Flux. 1 – For us this strikes best balance of realism and details. Image was generated in 1024×1024 resolution. Flux models are larger than both SDXL and Pony so it requires even higher VRAM use. Interestingly image generation with flux was 2-3 times faster with same parameters as SDXL/Pony.
Even though Flux.1 is clearly most capable image model, we simply can not recommend it yet. This is because of restrictive licensing that comes with Flux.1. Because of this and higher gpu demand there are not many community finetunes and loras available for it.
Our recommendation is to go with either SDXL or Pony(SDXL for general use, Pony for more hardcore images) and pick SD1.5 only if your GPU does not support it.
I’ve Decided — Now What?
So you’ve picked your base model — great! Now it’s time to find a fine-tuned version of that model that’s been trained specifically for NSFW content.
The good news? You don’t have to train it yourself.
Most NSFW creators use community checkpoints, which are versions of SD 1.5, SDXL, or Pony that have already been trained or merged to produce high-quality, uncensored results. These are easy to download and plug into your favorite generation tool.
Where to Find Them
The best place to start is Civitai.com — the largest community hub for Stable Diffusion models, LoRAs, embeddings, and more. Just search for the base model you picked (e.g., “SDXL NSFW” or “Pony Diffusion”) and browse by popularity, style, or recent uploads.
A Few NSFW Image generator models we Recommend
Note: We’ll have a full breakdown of the best community models for each base model in an upcoming article — so stay tuned.
In the meantime, here are a few popular and reliable picks:
- SDXL:
- epiCRealism XL – Great for NSFW people and realistic scenary in general. In our testing this model produced images that are very normal looking. But, in our testing, it’s a bit difficult to get hardcore NSFW images with this model by default. Also, as name suggests model is not so good at generating anime.
- Autism Mix SDXL – Amazing for anime, especially hentai, very creative and compliant model. These are it’s weaknesses: Hands(Very hard to get correct finger count). Character sheets and multiple people(Sometimes model generates extra people or character shee), we partially solved this issue with negative prompts, but it still gives us problems from time to time.
- Animagine XL – Amazing at anime, not as good in hentai. This model was designed to know about popular anime characters. In our testing model is really good at following prompts, but it’s not as good with hentai.
- RealVisXL – Great realistic model that produces really good stylized images. In our testing images look more professional than epiCRealism. In general, model was great at generating nudes, but we had trouble generating hardcore scenes.
- DreamShaper XL – Swiss army knife of Ai models. It’s good at generating everything from realistic to anime. Only downside is that compared to dedicated realistic and anime models it’s lacking some details.
- Pony:
- Pony Realism – This is our favorite People model. It produces amazing, detailed images and is really good at following prompts(Both: SFW and NSFW).
But, it has severe limitations:- Men – It is capable of generating men, but this was clearly not the focus of the model.
- Scenary – It wants to add people to all images. There are ways to avoid this but realistically, if you care about generating scenary etc, we can’t recommend this.
- Anime – Non existant.
- Despite these limitations, if you just want to generate realistic women, you can’t go wrong with this model.
- Autism Mix Pony – Pony version of Autism mix.
- Base version of Pony – Fully uncensored and great for generating pony.
- WAI-ANI-NSFW-PONYXL – Great at generating very stylized anime images.
- Pony Realism – This is our favorite People model. It produces amazing, detailed images and is really good at following prompts(Both: SFW and NSFW).
- SD1.5:
- DreamShaper – SD1.5 version of DreamShaper. Balanced model capable of generating both realistic and anime images.
- AbyssOrangeMix3 – Model focused on anime
- Realistic Vision – Great for generating realistic images
