Qwen Image 2.1 LoRAs: distinguish trainer support from downloadable adapters
A trainer implementation is not a catalog of trained adapters. Track exact bases, adapter files and loader evidence separately.
What has been established
The reviewed AI Toolkit commit includes a Qwen-Image 2.1 implementation under architecture identifier qwen_image_2, using the 2.1 configuration and components. Q10 That establishes code presence, not a training run completed by this site. RunComfy's training page is retained as a source for its own service, not independent proof of compatibility. W04
Inspect an adapter's actual base
The LoRA catalog stores base model and version independently from tags. SDXL, FLUX and earlier Qwen adapters do not become verified 2.1 adapters because they share a file extension. Relationships without an author declaration or test remain unknown rather than being guessed in either direction.
Define the task before the recipe
Describe the target output, reference roles and evaluation procedure before choosing settings. A transparency task needs genuine alpha examples, not white backgrounds or painted checkerboards. Keep a base-model comparison and evaluate adapters using held-out inputs. These are editorial experiment-design recommendations.
This batch's catalog status
The two newly cataloged adapters are SDXL-Lightning 4-step and Hyper-SD SDXL 8-step. They establish a versioned directory structure; neither is labelled Qwen 2.1 compatible. This batch has not verified a specific downloadable Qwen 2.1 adapter. Trainer code, tutorial pages and full quantized checkpoints are not counted as LoRAs. This is a collection boundary, not a claim that no such adapters exist online.
Rights and provenance
Keep base-model and adapter terms separate and retain the file identity. A license badge is not an automatic grant for every use in the dependency chain. The Qwen 2.1 research license calls for separate consideration of commercial use. Q02 Link to original weights rather than hosting them, and never run uploader scripts as part of metadata collection.
