To me they are clearly AI generated but I have a very well trained eye to spot them, to generate them download a custom model from civitAI and a LoRA of the particular anime character you want to generate, then used them with automatic webui or ComfyUI (maybe also invokeAI).

Thanks for the keywords. I've given a few googles of those words to see what you're talking about. So it seems like CivitAI has base models / training data. This seems to be more of the base artistic style for StableDiffusion or something to draw off of. LoRA is some program to tweak models / training data into a specific style (but needs a base style to work with). So the combination of those two techniques seem to generate characters (especially an anime/cartoon, where there's a lot of reference art from the show to take). But since some characters are very popular (Konosuba is a very popular anime), the LoRA would have already been done (and is possibly being shared on forums online somewhere??). So the advertiser probably just downloaded (base model) + community-sourced LoRA of the Konosuba anime, and then used a prompt to create the advertisement? Finally, take a classic "pin-up" model shot to provide a sexual base image and bam. Automatic, low effort image that probably gets a lot of clicks.

  So CivitAI is a library where people upload custom models, LoRA etc... But no training data; custom model are full Stable Diffusion model finetuned on something, LoRAs are also weights but they are not the full checkpoint, with LoRA you are able to add knowledge to the model that do not required the entire model to be finetuned (for example adding a character). If a character is popular there will be already many LoRA trained on them (like the characters of Konosuba) >So the advertiser probably just downloaded (base model) + community-sourced LoRA of the Konosuba anime, and then used a prompt to create the advertisement? Yes.
