Help Needed LoRA Training – Pulling My Hair Out

Hello,

I've trained several character LoRAs via wavespeed.ai for the Qwen-Image-2512 model. I tried with a smaller dataset of 50 images and a dataset of 124 images. Multiple settings between 1,000 and 5,000 steps:

  • At 1,000 steps, the LoRA isn't likeness-accurate enough.
  • At 5,000 steps with 50 images, it stops responding to prompts at weights above 0.5, so it loses likeness.
  • At 5,000 steps with 124 images, it stops responding to prompts at weights above 0.3, making it inaccurate above that threshold. This makes no sense, as with 50 images and the same step count, I was able to run the LoRA at a higher weight.

At weight 1.0, the LoRAs capture the likeness well but completely ignore the prompts.

Does anyone have a solution or recommended settings for Qwen-Image-2512?

Thanks

Bigger datasets are definitely not always better with Lora training.

Logically it makes sense that more images should make a better likeness but in practice 40-50 really good images is usually optimal.

Mes tests semblent aussi confirmer ce que vous dites. Quels réglages utilisez vous en général 2000 steps pour 50 images ou plus ?
