Qwen Image 2.1 masked inpainting: working crop-and-stitch graph, wiring and prompting differences from Flux

Reasonable_Arm7239 · reddit · 2026-09-24

The author shares a full migration of their Flux inpainting workflow to Qwen Image 2.1. Key wiring: the cropped image goes into image1 on TextEncodeQwenImage21 (the VL encoder itself is the reference mechanism, no ReferenceLatent), and the sampler latent must come from InpaintModelConditioning. Prompting is the bigger change — 2.1 is an instruction follower, so "replace the masked object with X" beats Flux-style descriptions. Also covers negative prompts (live at CFG >1), crop-and-stitch params, addressable multi-image references, bf16 fits on 24GB, and a research/non-commercial license.
