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.
Description
TurboVisionXL Beta 1.3.1 Release Notes
Meet the first update for TurboVision. This has had 8 different tunings applied from my previous model trainings to attempt to curb some of the more troublesome coherence problems and improve the model's 1 shot output. This still works best at 5 steps with DPM++ SDE Karras.
ChangeLog 12/1/23
Added the following (internal only) tunings:
SCG-Detailer-v1
SCG-Detailer-V2
CVXL-Detailer-007
CineClassic-007
SCG-Classic-Cinema-009
Stylevision-tune-020231120
SCG-Cinematic-Detailer-V1-000010
Analog-photography-v2-00008
Known Issues
Coherence is improved over 1.0.1, however it's still not where it needs to be. Expect occasional twinning, floating hands, extra fingers, etc. The next update mostly solves this, but for this version you will still have occasional coherence badness.
Male Genitalia
Eyes and faces at distance (surprisingly improved over other XL models, but still not "good")
