This is a place for experimenting with SD1.5 LoRA.
The main goal is overall enhancement rather than focusing on a single concept.
■Dora_nsfw_remember is intended to complement my test merge model, but since the training is done on NovelAI v1, they should work fine with its derivative models.

■nai_v2_highres is a high-resolution stabilizing DoRA for novelai_v2.
Please download the official checkpoint from the URL below.
I’ve also made a safetensors version just in case.

■nai_v2_semi-real is a semi-realistic style DoRA for novelai_v2.
■I use OneTrainer for training and ComfyUI for inference.
■I will share my training settings and inference workflow as much as possible.
■If the prompt is short, the background may become simple or the style may lean toward realism.
By using the uploaded tipo_workflow, you can automatically generate longer prompts—so please give it a try!
■Sometimes saturation occurs due to overfitting and the model’s compatibility. Adjusting DoRA , prompt weight strength, or reviewing the cfg can help improve this.
■There’s also a high-resolution inference workflow using kohya_deep_shrink.
It expands composition and removes the need for high_res_fix.
1152px offers a good balance of quality, stability, and speed, while 1536px is more dynamic and detailed.
By the way, this Dora was created to give SD1.5 a level of concept understanding comparable to my PixArt-Sigma anime fine-tune.
SD1.5 with Dora applied will likely be the most compatible refiner—it's ideal for i2i tasks.

Description
● Trained Dora on a dataset of 400,000 images.
● The goal was to create a Dora model that maintains the original style while enhancing tag recognition and overall quality.
By adding "realistic , figure, anime screencap" images, these styles have been further strengthened. It works if you add each style tag to the prompt.As shown in the sample images, even an anime model can generate somewhat realistic-style images.
●Dataset Contents
Concept enhancement: 240,000image
Aesthetic enhancement: 130,000image
figure+realistic:30,000image
●This Dora does not have trigger tags. The goal is general concept enhancement, not restricting the original model.
This is not a major modification; it's just guiding concepts that the model already knows but have been buried and are not functioning properly.
●I aimed to evenly learn as many concepts as possible. On its own, the effect is weak, so using multiple related tags may be necessary.
If the character has long green hair, it's best to include those tags. The same applies to NSFW tags.
● If you want to reinforce specific concepts, adding a single-concept LoRA is recommended. Using Dora_nsfw_remember_v001 alongside it is also effective, as v001 focuses more on specific concepts and provides additional support.
●There may be occurrences of "censored, mosaic censoring, bar censor" but that is because these are included in my dataset. I also include uncensored images, but many images have censorship. You can enjoy them as expressions or spice, or try adding them to negative prompts. It might also be a good idea to add "uncensored" to the prompt, although it might not always resolve the issue.
● Training was done on NovelAI_v1, so it should work with its derivatives.However, some models suffer from concept forgetting due to overfitting on specific concepts or styles. What works in NovelAI may be weaker elsewhere. Increasing the LoRA weight above 1 or strengthening the tags might help.There are few issues up to a strength of 1.5. Conversely, if artifacts increase, try lowering them.
●Be careful with negative prompts.
Using terms like "worst quality, low quality:1.4" can easily produce high-quality images, but they may limit diversity.
If special tags like "slime girl" don’t seem to have an effect, the strength of these negative prompts might be too high.
●With short prompts, the background may become more plain, and the style may lean toward realism.
In that case, try adding background tags or including as many details as possible, like clothing and hairstyle, to better define the image you want to generate.
●Only general tags and character tags have been trained.
While the work’s title hasn’t been specifically trained, some character names include the title, so you might get lucky and see some reinforcement.
However, since characters and works were not the focus of the training, they may not be well-learned—so please don’t expect too much. For characters, adding a single-concept LoRA would likely be more effective.
●This LoRA is designed for 512px, so using it at higher resolutions may sometimes cause distortions.Turning off Dora during high-res fix or i2i upscaling may result in clearer images with fewer distortions.
●I'll also share my OneTrainer settings for reference.
This is U-Net-only training. Training with Clip Skip 2. For OneTrainer, it's set to 1.I'll also share my ComfyUI workflow just in case.
