Just add BREAK after it (for A1111 and derivatives), use conditioning concat node (for Comfy) <strong><u>or at least put them in the very end</u></strong>. Otherwise, significant degradation of results is likely.</p><p></p><h2 id="basic:-aroav4616">Basic:</h2><p></p><p>The checkpoint works both with short-simple and long-complex prompts. However, if there are contradictory or weird things - unlike with others they won't be ignored affecting the output. No guide-rails, no safeguards, no lobotomy.</p><p>Just prompt what you want to see and don't prompt what shouldn't be on the picture. If you want to have a view from above - don't put ceiling into positive, if you want to have crop view with head out of frame - don't make detailed description of character facial features, and so on. Pretty simple but sometimes people are missing it.</p><p></p><p>Version 0.8 comes with advanced understanding of natural text prompts. <u>It doesn't mean that you are obligated to use it</u>, tags only - completely fine, especially because understanding of tags combinations is also improved.</p><p>Do not expect it to perform like Flux or other models based on T5 or LLM text encoders. The whole size ot SDXL checkpoint is less then only that text encoder, in addition illustrious-v0.1 which is used as the base completely forgot a lot of general things from vanilla sdxl-base.</p><p>However, even in current state it works much better, allows to do new things usually impossible without external guidance, as well making manual editing, inpainting, etc more convenient.</p><p></p><p>To achieve best performance you should keep track of CLIP chunks. In SDXL the prompt is separated into a chunks of 75 (77 including BOS and EOS) tokens, that are processing by CLIP separately, and only then are concatinating and comes as conditions to unet.</p><p>If you want to specify some features for character/object and separate them from other prompt parts - make sure they are in the same chunk and optionally separate it with <code>BREAK</code>. It will not solve problem of traits mixing completely, but can reduce it improving overall understanding, since text encoders on RouWei are able to process the whole sequence, not individual concepts better then others.</p><p>Dataset contains only booru-style tags and natural text expressions. Despite having a share of furries, real life photos, western media, etc. all captions have been converted to classic booru style to avoid a number of problems from mixing of different systems. So e621 tags won't be understanded properly.</p><p></p><h3 id="sampling-parameters:-7andwk13p">Sampling parameters:</h3><ul><li><p>~1 megapixel for txt2img, any AR with resolution multiple of 32 (1024x1024, 1056x, 1152x, 1216x832,...).

Autocomplete extension might be very useful.</p><p>Most characters are recognized just by their booru tag, but it will be more accurate if you describe their basic traits.

Better to keep it clean, short and convenient description works best. Better <strong><u>not</u></strong> use long and sloppy BS like</p><pre><code>A mysteriously enchanting feminine entity of indeterminate yet youthful essence, whose celestial visage radiates with the ethereal luminescence of a thousand dying stars, blessed with locks cascading like the golden rivers of ancient mythology, perhaps styled in a manner reminiscent of contemporary fashion trends though not necessarily adhering to any specific aesthetic paradigm.

Without low brightness or low gamma or limited range (in negative) it might be difficult to achieve true 0,0,0 black, the same often true for white.</p><p>Both epsilon and vpred versions have like true zsnr, full range of colors and brightness without common flaws observed. But they behaves differently, just try it.</p><p></p><h1 id="vpred-version-9pr2w5h4d">Vpred version</h1><p></p><p>Main thing you need to know - lower your CFG from 7 down to 5 (or less). Otherwise, the use is similar with advantages.</p><p>It seems that starting from v0.7 vpred works flawlessly now. It shouldn't suffer from ignorance of tags close to the 75tokens chunk borders like nai. It is more difficult to get burned images - even on cfg7 usually it just over-saturated but with smooth gradients, which can be useful for some styles. Yes it can make anything from (0,0,0) to (255,255,255). You will find brightness meta tags described above quite useful for easier/lazy prompting, natural text expressions also work. To get the most dark image - put <code>high brightness</code> into <u>negative</u> and/or use <code>low brightness, low gamma</code> tags. If you don't like very bright skin on dark background and want to reduce contrast (or on the contrary, enhance the effect) - use hdr/sdr in negative/positive.</p><p>It was reported that in rare cases on some prompts there is a drop in contrast. Looks like other vpred models have same behaviour with such prompts, adding a "separator" closer to the border of the 75-token chunk fixes this. However, with 0.7 I haven't encountered this myself.</p><p></p><p><span style="color:rgb(134, 142, 150)">To launch vpred version you will need dev build of A1111, Comfy (with special loader node), Forge or Reforge.
