( Not my Model )

Introducing RAYFLUX v3 AIO

AIO is the next gen in my RAYFLUX line, where Photoplus was technically v2.
It brings back some of the creativity of v1 to Photoplus, and is now all baked in with T5, Clip and VAE, meaning you can load it and use it with a normal Load Checkpoint workflow in Comfy.

Hope you'll enjoy,

R.

HOW IS IT DIFFERENT?

AIO is a new attempt at a model that good at photography but also performs well on creativity and general non-photo subjects. It is a dataset merge from v1 and Photoplus, with some custom LoRA merge-in and some manual block weight tweaking. I've re-upped the model to FP16 but used some optimizations to keep the full based model which includes the VAE , T5XXL-FP16 and the ViT-L-14-BEST-smooth-GmP-TE-only-HF-format from Zeroint already baked in while keeping the size on the reasonable side. The model isn't without it's quirks but responds actually better than Photoplus in a lot of subjects so I decided to go ahead and share it.

TL;DR: AIO will perform well on basically anything you throw at it, and tries to retain the slightly grain photographic style Photoplus brought, but more creative.

SETTINGS

AIO shine with a specific combination in my opinion dpm_adaptive with ddim_uniform . All the settings used for Photoplus or v1 will keep working, but the results are just more creative using this specific combo

• Unlike the other RAYFLUX models, max shift and base shift can be tweaked, with a good range being around 1.2-1.8 on max, versus 0.5-1 on min. Flux Guidance works best at a lower value, 2-3 seems to be the best range.

• As a reminder, RAYFLUXv1.0 used Heun/beta and Photoplus DPM_adaptive/beta.

• For steps, AIO works great between 14 and 20 steps.

• As a note, AIO works great at 2MP resolutions too! (see some examples below)
  

I usually do a second pass with a SD upscale at 2 steps with denoise at 0.2-0.3 . I switch the upscaling model depending on the style I'm looking for e.g. 1x_ITF_SkinDiffDetail_lite for grainy portraits (works great at x2 too!), 4xUltrasharp for generic illustration, 4x_Foolhardy_Remacri for softer, cleaner digital illustration style. The prompt you use on the SD upscale is very important in general, don't hesitate to abuse it to nudge the upscale in the direction you want (i.e. write grainy for more grain, soft for less grain, add details about your protagonist, etc.)

KNOWN ISSUES/QUIRKS

• Nipples, male or female. There's a distinct lack of nudity in my dataset and somehow this version isn't helping much with that. There's a ton of LoRAs out there for it though, so it's not too dramatic.

• it's slower and more VRAM hungry than the previous versions. With a checkpoing clocking at 21GB (although it includes T5, Clip and VAE so the UNET's footprint stays around 16GB). It takes 50-60s to generate a single 2MP image on a 4090.

• There's way more variation seed to seed as a result of my tweaking and compared to the previous 2 models, which is a good thing imho, but also makes it a bit more work to domesticate.

• Baking in encoders really did improve a lot model response, and easy of use, but somehow makes GGUF quantization trickier as I'm playing with different precision in the blocks of the base model (which started as a FP8 re-upcasted to FP16 before additional training). User foggyghost0 in the comments also reported some encoding precision issues, so please be patient while I sort this out.
