Flux.1 Krea Comprehensive Samplers and Schedulers XY plot

I know... its an old fat dude. Its my beloved husband.

The idea was to push and see what samplers do with hands and feet and other stuff. Lots of people deafault to the beaten path like "euler+ simple" and such - which is fine if you are looking for something predictable and stable for consistency and efficientcy.
If you are looking to get creative - try some of the weird combos, they might look bad on the "straight" grid but once you start adding loras and hone the prompt - some really nice surprises happen.

One of my favorite discoveries is ipndm_v + kl_optimal - it can take 8-12 loras and still be ok and it adds a "vanta_black" kinda effect by itslef.

linear_quadratic and kl_optimal have interesting flare almost like instagram filters.

sa_solver_pece is becoming my favorite - keep in mind "solvers" are slower but worth it.

The only samplers not included are LCM - since its a lightning thing and CFG ones - which are designed for high CFG workflows and Flux is only at CFG 1.

I am a traditional oil on canvas painter, so I mostly try to break things - push it from photorealism to an artistic style, which Flux doesn't understand well, but its good to see that Krea version is a bit better with painterly styles.

Enjoy ;)
