A pinned local Qwen editing recipe versus HF-advertised hosted image-to-image support: exact inputs, controls, model/adapter boundaries and unresolved provider terms. Documentation comparison; no output generated or equivalence proven.

For editing an existing image while preserving the subject, distinguish a version-pinned local model from an advertised hosted route. The inspected Qwen-Image-Edit-2509 card reports better face/product consistency; it provides no preservation guarantee, and no output was tested here.

Local open-weight workflow. Use the Qwen/Qwen-Image-Edit-2509 card at d3968ef930e841f4c73640fb8afa3b306a78167e. Its example loads QwenImageEditPlusPipeline in bfloat16 on CUDA, supplies an ordered two-image list, a text instruction, seed0, true_cfg_scale4, guidance_scale1, 40 steps, a single-space negative prompt and one output. Its preferred one-to-three-input range is vendor guidance, not a measured limit from our review. The card declares Apache-2.0. Pin the separately installed Diffusers code: the example installs moving main. No 12-GB fit, quality or latency result is established.

Hosted candidate. The captured HF public mapping advertises Qwen/Qwen-Image-Edit-2509 live for image-to-image via WaveSpeed and fal-ai. HF's documented WaveSpeed InferenceClient takes image bytes, an editing prompt and a model ID. Combining that client interface with the captured mapping gives a proposed call with provider=wavespeed and model=Qwen/Qwen-Image-Edit-2509. This is an assembled, unexecuted recipe: the rendered guide's own example uses another model. Use an account token with Inference Providers permission; supply a permitted image and precise editing instruction, then save the returned image and request metadata if later execution is authorized.

The hosted route does not establish the local recipe's full interface. HF's generic task schema documents one image payload and several optional settings. In the separately inspected huggingface_hub SDK at a43cbe33148ae6f7ca27568922c1968b69e822d8, InferenceClient.image_to_image forwards extra keyword arguments to the provider helper, and the WaveSpeed helper serializes non-None parameters beside a single image value. Thus passing a field through the client can be distinguished from the backend accepting or applying it. This source does not establish Qwen-specific seed/true_cfg_scale effects, multi-image backend support, checkpoint equivalence or reproducibility. The primary image argument is converted from a URL, file or bytes; this helper contains no list-input conversion. These are static-source observations, not an executed request. target_size can be ignored for unsupported providers/models. The WaveSpeed mapping names wavespeed-ai/qwen-image/edit-plus-lora but supplies no upstream weight commit, quantization or adapter configuration. That name alone proves neither base-checkpoint equivalence nor an active adapter. The separate dx8152/Qwen-Edit-2509-Multiple-angles mapping explicitly marks adapter=lora and names adapter weights; keep that route distinct from the base model.

Use terms and data handling. Qwen model licensing, HF documentation licensing and hosted service conditions are different components. The HF hub-docs sources are Apache-2.0 at f726ac870c1c91810630ff84f9a6ab6d0d6936b6; their license does not grant hosted-service or input-image rights. HF's security page describes its router and directs users to each provider's policy. It cannot establish WaveSpeed retention or training practices for this exact route. Applicable HF/provider contracts, model conditions and input/output rights must be checked before use; no blanket commercial authorization or zero-retention claim is made. Provider terms were inspected separately, and originals are excluded from this packet.

Practical procedure (curator-designed, not tested). Start with one identical permitted image and one defined change. For example: change the jacket color to navy while preserving face, pose and background. Treat that wording as a proposed instruction, not a tested prompt. Hash the input; record its order, the exact prompt and all exposed parameters. For local work record the model/library commits, scheduler, dtype and hardware; for hosted work record provider, model ID, providerId, request ID and returned metadata. Inspect subject identity, text and intended versus unwanted changes separately. Keep failed outputs. Record actual cost, latency and reproducibility only after an authorized run. Local inference is a candidate when checkpoint/environment control matters; hosted inference is a candidate when its exposed controls and external processing conditions suit the task. This comparison ranks no output quality.

Evidence: original retained documentation and public metadata, source_inspected/not_run/unreviewed. Mapping entries are metadata_checked advertised support, not successful availability receipts. All reviewers share the founder operator. No API generation, model installation, source-media inspection or formal independent review occurred.
