FLUX 2 vs FLUX SRPO, New FLUX Training Kohya SS GUI Premium App With Presets & Features

Tutorial Video Link

https://youtu.be/RQHmyJVOHXo

Info

FLUX 2 has been published and I have compared it to the very best FLUX base model known as FLUX SRPO. Moreover, we have updated our FLUX Training APP and presets to the next level. Massive speed up gaings with 0 quality loss and lots of new features. I will show all of the new features we have with new SECourses Kohya SS GUI Premium app and compare FLUX SRPO trained model results with FLUX 2.

More Info

  • In this video, I demonstrate the newest improvements and features added to our SECourses Premium Kohya Trainer (v35). We have achieved massive performance gains and VRAM reductions, allowing for high-quality FLUX training on GPUs with as little as 6GB of VRAM using the FLUX SRPO model.

  • I also break down the brand new FLUX 2 announcement! We perform a side-by-side comparison between my locally trained FLUX SRPO model, the base FLUX 1 Dev, and the newly released FLUX 2 Pro model to see if it’s time to switch workflows.

🚀 Key Updates Covered:

  • Full Torch Compile Support: Now enabled across all presets for faster training speeds.

  • FP8 Scaled LoRA Training: On-the-fly conversion that drastically reduces VRAM usage (0 block swaps on 24GB cards) with zero quality loss.

  • New Tools: Introducing the "FLUX FP8 Converter" to shrink DreamBooth models to 11.1GB and a new "Image Pre-processing" tool to visualize exactly how Kohya sees your dataset.

  • Hardware Optimization: New presets ranging from 6GB VRAM consumer cards up to 80GB A100/H100 configurations for lightning-fast training.

  • FLUX 2 Analysis: A realistic look at the 32-billion parameter giant and how it compares to our optimized FLUX 1 workflow.

Another question I had is have you had any success using Prodigy as an optimizer ? Thanks

SECourses: FLUX, Tutorials, Guides, Resources, Training, Scripts · December 1, 2025

i tested it extensively and sadly not

Hugo Morosini · November 29, 2025

i'm having low likeness doing a flux dev finetune with "80GB_GPUs_60GB_VRAM_Quality_1.json". I'm not changing any parameters beside the model paths, is there anything I should enable / disable ? I've noticed many things such as "fused_backward_pass" are now disabled, is that normal ? Thanks

fused_backward_pass just impacts speed. so improve your dataaset. you can see example dataset here : https://www.patreon.com/posts/114972274

Will Flux2 be trainable as Lora or Full Checkpoint with your Kohya Training App?

SECourses: FLUX, Tutorials, Guides, Resources, Training, Scripts · November 28, 2025

yes hopefully with musubi tuner app

Roni Bliss · November 28, 2025

Vs Z-Image ... Flux 2 was just murdered in cold blood. All blck forests years of work down the drain. Flux 2 isnow the new SD 3.5 cast into the shadows a slow clunky relic. WOW
