TurboVisionXL - Super Fast XL based on new SDXL Turbo - 3 - 5 step quality output at high resolutions!

TurboVisionXL Version 2.0 Release Notes I've developed a better pipeline for updating this model while preserving its ability to generate good images at usable resolutions and aspect rations. I've got it pretty solid at 1024 x 1024 now, though you still have an increased amount of twinning and weirdness when pushing towards the 16:9 and 21:9 ARs. 2:3 and 4:3 work pretty well. Please note the style of this model is still a bit in flux. While I mixed it originally off of DynaVision, my goal is to make this model more general purpose and capable of pushing other art styles. The training in this version has added more photographic and cinematic quality, but still produces fun chibis and anime style output with minimal prompting. This version produces "usable" output as low as 3 steps, but 5 steps is still the sweet spot. Regarding samplers, I've found you can use the DPM++ SDE sampler in Auto1111 and it produces similar quality output to DPM++ SDE Karras but faster. ChangeLog 12/4/23 - Merged with an (internal only) turbo-ized version of NightVision which brought in improved coherence and better handling of wider AR's. also seems to have mostly stabilized 1024x1024 output. - 3 new trainings on cinematic photography, widescreen AR images, and more coherence focused tuning. - finished with a light backmerge with a tweaked version of XL Turbo. Known Issues - coherence is still wobbly, but improving rapidly version to version. Almost as coherent as my mainline models now. - twinning on non-square ARs can occur - hands, male genitalia and distant faces - Doesn't work with refiners (just not enough steps to give a refiner time to work) - issues with ADetailer...? (reported from comments, I can't confirm this - use Face Editor instead if its broken for you, Face Editor works fine with Turbo in my experience) - Multipass (3M and 2M) samplers are hit or miss - they're just not able to resolve fast enough versus the other samplers or they introduce errors on the multipass. best stick to the single-pass samplers for Turbo. - Restrictive Licensing - SDXL Turbo is being held on a research license by SAI currently. This is out of my hands - I choose to honor open source licensing rules, and thus, I cannot make this model available for onsite generation, as that is against the license on the base model. As soon as SAI removes the license restriction, I will allow monetization and generation options!
