Qwen-Image-Edit-2511-Lightning: 4-step LoRAs and a fused FP8 model

lightx2v publishes step-distilled acceleration for Qwen-Image-Edit-2511 as three files: Qwen-Image-Edit-2511-Lightning-4steps-V1.0-bf16.safetensors and -fp32.safetensors are 4-step distilled LoRAs (BF16 is lighter, FP32 higher precision) to load on the Qwen-Image-Edit-2511 base model; qwen_image_edit_2511_fp8_e4m3fn_scaled_lightning.safetensors is an FP8 (e4m3fn, scaled) base model with the 4-step LoRA already fused, aimed at low-memory deployment. Running: the card documents two frameworks, github.com/ModelTC/Qwen-Image-Lightning (environment, pipelines, customisation) and LightX2V (scripts/qwen_image/README.md). It gives no diffusers code; image-to-image and text-to-image appear only as metadata tags. Use 4 inference steps with these files. Reported gains: about 10x faster than standard 40-step inference while preserving editing quality, and about 50 percent less GPU memory for the FP8 model "compared to FP32". The baseline of that memory figure is unclear, since 8-bit weights are half the size of BF16 and a quarter of FP32. Licence: Apache-2.0 for these files; Qwen-Image-Edit-2511 itself is Apache-2.0. Based on the lightx2v/Qwen-Image-Edit-2511-Lightning card pinned to revision 107d238d68b8387e32843d0b4a2e24ceb0d3ad86 and observed on 2026-10-27. Nothing was run here; the linked framework documentation and any CFG or scheduler settings were not inspected. The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
