[NSFW] Diffusion models for porn generation

In plain words

This AI tool generates adult content using diffusion models, launched in June 2022. It is designed for users seeking to create custom explicit imagery through text prompts. The product applies diffusion-based generative technology to adult material production. Users can input descriptions to generate corresponding images. The tool represents an application of machine learning techniques to the adult content creation space.

From the sources

This is a week-end experiment of applying diffusion models, the same technology that powers Dall-E 2, to adult-content generation. Loosely inspired by Denoising Diffusion Probabilistic Models https://arxiv.org/abs/2006.11239 , Cascaded Diffusion models https://arxiv.org/pdf/2106.15282.pdf and https://github.com/openai/guided-diffusion Models have been kept small so that the training could be done using 2 1080Ti in a week-end. Training was done on ~500k video frames (extracted at one frame eachfrom orchid.gistnoesis.net

  Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.

  Tiny Diffusion – A character-level text diffusion model from scratchNov 2025 · github.com · ▲172

  I previously posted this a month and a half ago: https://news.ycombinator.com/item?id=45876742 I have rewritten it to be much more simple, from 951 lines of code to just 364, with no loss in core functionality or generation quality. I also added a tiny GPT implementation as a comparison (inspired by Andrej Karpathy's code). The two model implementations are ~80% identical, with the core differences being the generate and get_batch functions. The model architecture, training loop, etc, differ in only 19 lines of code. Trained weights are included, so you can just clone and run…

  A few months ago, I started making video clips with stable diffusion and noticed that the tools to do this were too complicated for everyday people. That's why I built neural frames. Enjoy.

  A friend and I spent 6 years making a simulation game, finally released▲1,157

  I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…
