Settings that work
- Train Turbo with ai-toolkit's distillation/training adapter
- One model for generation and edit; it edits when the dataset has control images (ai-toolkit README)
- ai-toolkit default guidance for Qwen Image: 3
- LoRAs trained on the non-Turbo model transfer to Turbo, but adapter-trained Turbo LoRAs come out better
- Stronger than FLUX.3 for edit-style LoRAs on the same dataset
- diffusers main (Oct 22, PR #15016): Qwen-Image LoRAs with .alpha keys now load with alpha scaling applied; before, they loaded at the wrong strength in diffusers
- diffusers v0.42.0 (Oct 23, PR #14976) adds Qwen-Image 2.1 modular pipelines
- Qwen-Image edits shift and stretch the image slightly; the Qwen2.1 Align ComfyUI node aligns the edit back to the original (SIFT + RANSAC global affine, no model or GPU needed)
- The lightx2v 4-step Lightning LoRA shifts edits to the left; at strength 0.5 the shift goes away. Lightning-v2-RL shifts less at slightly lower quality
