Wow guys, you have to try this for yourself! ??

Super fast generations at "normal" XL resolutions with much better quality than base SDXL Turbo!

Suggested settings for best output

Sampler: DPM++ SDE or DPM++ SDE Karras

Steps: 3 - 5

CFG: 1 - 2.25

You can run this model in Automatic1111 like a normal XL model, however not all samplers work with it. I've found DPM++ SDE is the best output performance in the 3 - 5 range, while DPM2 looks really good in the 6 - 10 step range if you're willing to wait just a bit longer. The LCM sampler and Euler A produce almost identical output, which is usable at low steps, but really lacking in detail vs. the other options.

LoRAs work fine, I've tested multiple LoRAs and they appear to still produce expected results, tho YMMV of course.

Coherence is a work in progress with this model. 1024 x 1024 is pretty well solved now, and I very rarely see errors even in 4:3 and 2:3 formats. 16:9 does result in some twinning, but it's not too bad. 21:9 is rougher with an annoying amount of twinning and errors, though not too much worse than normal mainline models.

NOTE ON LICENSING - This model is based on the SDXL Turbo model released by Stability AI. They have flagged the model as being released under a non-commercial research license and permits personal, non-commercial use only. Be aware this model cannot be used for image generation services at this time. If you have questions, please reach out to me on Discord.

TurboVisonXL V4.3.1 Release Notes

Merry Xmas!!! This version includes multiple trainings working on coherence, especially for widescreen (16:9, 21:9) output. While it's not perfect, I venture to say that TurboVision is as good as any "normal" SDXL model at this point, and in fact surpasses most models in terms of output quality and detail. While this model excels at outputting detailed coherent output in the low 3 - 6 step range, it continues to add more detail and quality the higher you get. One of my favorite tricks right now is to generate images at 5 steps then img2img with the same prompt for 30 steps with DPM++ 3M SDE Karras with denoiser at 0.55. You can even use Turbo as a FInisher for other models as well, try it!

Eyes, faces, hands. all are greatly improved. hands especially seem to really have improved, especially when inpainting.

Changelog 12/23/23

• 2 new trainings with several hundred widescreen images of different aspect ratios and dimensions, resulting in much improved wide coherence

• low-value back-merge with CineVision

Known Issues

• male genitalia

• output is on the warm side. My next trainings I'm going to focus on cooling the color temp down a bit, but in the meantime if it's too warm, add "Yellow tone, sepia" to your negs and it should cool it off.

• hands and faces can be goofy at medium distances
