Separate the edit target from supporting references and understand resolution and latent sizing. Sixteen UI slots are not the model’s documented reference budget.

Models, files and workflows
Page 2Verify the reviewed template’s component selections, 25-step setting and 1MP baseline before moving to 2K. Keep Diffusers defaults separate.
This reference is not a combined download list for Qwen-Image-Edit or every later similarly named model. Select the intended text-to-image template first.
A .safetensors header parsing failure can involve an incomplete or wrong download, a different format or a parser/loader mismatch. The message alone does not uniquely prove corruption.
Use the official baseline to learn node roles and establish a working environment without installing a large custom-node collection. This is an instructional path, not a generated example tested by this site.
This reference explains the roles in official SDXL examples, not a benchmark of every derivative checkpoint or a claim that every LoRA is interchangeable.
Identify the official 4-step adapter by base family and file. Keep it separate from the repository’s full checkpoints and other step variants.
One operation may receive an image on CUDA and a mask on CPU, or branches on different GPUs. This does not mean the whole application failed to recognize the GPU.
A dtype failure differs from a shape or device failure. Start with the traceback and incompatible operand types; a KSampler error alone does not identify the component that caused them.
Matrix dimensions help locate a failure during sampling, encoding or adapter use, but one numeric pair does not identify a unique missing model.
This guide follows the 5B TI2V image-input path specifically. The model-family reference explains alternatives; this page handles input, execution stages and output verification.
Distinguish 5B TI2V from the 14B text/image-to-video routes. A shared Wan 2.2 label does not make weights, VAE, encoder and latents freely interchangeable.
A normal data-dependency loop prevents a valid execution order. This is different from a supported loop/control-flow node with explicitly defined semantics.
A displayed result, screenshot or resaved image may not contain recoverable workflow data. This alone does not indicate a broken import function.
An API execution node needs class_type. The same missing_node_type category may also report a class that exists in the request but is unknown to the backend, so read message and extra_info together.
