API README

Qwen Image Edit 2509 Lora Gallery

Qwen Image Edit 2509 Lora Gallery is the 2509 route for face to full portrait. It uses Qwen’s combined visual-semantic and appearance modeling to interpret subjects, relationships, typography, spatial structure, and surface detail as a connected composition, giving this exact route a clearer production purpose than a generic image request.

Use Qwen Image Edit 2509 Lora Gallery when the project specifically requires face to full portrait. State the creative goal, then define composition, viewpoint, wording, materials, lighting, and finish; for edits, explicitly separate the intended transformation from identity, layout, or regions that must remain stable.

Highlights

2509 Portrait extension. Expands a facial crop into a complete portrait composition.
2509 Facial identity continuity. Keeps the supplied person recognizable in the generated body and scene.
2509 Anatomically coherent completion. Infers plausible proportions, pose, clothing, and occluded structure.
2509 Art-directed wardrobe and setting. Uses the prompt to define presentation beyond the reference crop. The configured adaptation adds task-specific learned behavior.

Pricing

Configuration	Billing unit	Price
Base generation	Per request	$0.035

When to Use

✅ Good fit	❌ Consider alternatives
The project needs an existing image needs a controlled revision	The intended task belongs to a different media workflow
The available inputs match every required local field	Required source material or usage permission is unavailable
Creative direction can identify subject, style, and delivery	The output must be deterministic at pixel or waveform level
The supported route controls fit the final placement	Delivery requires unsupported formats or dimensions
An asynchronous generated result fits production	A live or frame-synchronous response is mandatory

Prompt Guide

Write the request as a production brief. Identify the subject or source, state the intended result, describe composition and visual or vocal character, then list exact preservation and delivery constraints. For edits, explicitly separate what must change from what must remain unchanged.
