# Qwen-Image-Edit-2509 Introduction
This September, we are pleased to introduce Qwen-Image-Edit-2509, the monthly iteration of Qwen-Image-Edit. To experience the latest model, please visit [Qwen Chat](https://qwen.ai) and select the "Image Editing" feature.
Compared with Qwen-Image-Edit released in August, the main improvements of Qwen-Image-Edit-2509 include:
* **Multi-image Editing Support**: For multi-image inputs, Qwen-Image-Edit-2509 builds upon the Qwen-Image-Edit architecture and is further trained via image concatenation to enable multi-image editing. It supports various combinations such as "person + person," "person + product," and "person + scene." Optimal performance is currently achieved with 1 to 3 input images.
* **Enhanced Single-image Consistency**: For single-image inputs, Qwen-Image-Edit-2509 significantly improves consistency, specifically in the following areas:
- **Improved Person Editing Consistency**: Better preservation of facial identity, supporting various portrait styles and pose transformations;
- **Improved Product Editing Consistency**: Better preservation of product identity, supporting product poster editing；
- **Improved Text Editing Consistency**: In addition to modifying text content, it also supports editing text fonts, colors, and materials；
* **Native Support for ControlNet**: Including depth maps, edge maps, keypoint maps, and more.
## Example Showcase
**The primary update in Qwen-Image-Edit-2509 is support for multi-image inputs.**
Let’s first look at a "person + person" example:
Here is a "person + scene" example:
Below is a "person + object" example:
In fact, multi-image input also supports commonly used ControlNet keypoint maps—for example, changing a person’s pose:
Similarly, the following examples demonstrate results using three input images:
---
**Another major update in Qwen-Image-Edit-2509 is enhanced consistency.**
First, regarding person consistency, Qwen-Image-Edit-2509 shows significant improvement over Qwen-Image-Edit. Below are examples generating various portrait styles:
For instance, changing a person’s pose while maintaining excellent identity consistency:
Leveraging this improvement along with Qwen-Image’s unique text rendering capability, we find that Qwen-Image-Edit-2509 excels at creating meme images:
Of course, even with longer text, Qwen-Image-Edit-2509 can still render it while preserving the person’s identity:
Person consistency is also evident in old photo restoration. Below are two examples:
Naturally, besides real people, generating cartoon characters and cultural creations is also possible:
Second, Qwen-Image-Edit-2509 specifically enhances product consistency. We find that the model can naturally generate product posters from plain-background product images:
Or even simple logos:
Third, Qwen-Image-Edit-2509 specifically enhances text consistency and supports editing font type, font color, and font material:
Moreover, the ability for precise text editing has been significantly enhanced:
It is worth noting that text editing can often be seamlessly integrated with image editing—for example, in this poster editing case:
---
**The final update in Qwen-Image-Edit-2509 is native support for commonly used ControlNet image conditions, such as keypoint control and sketches:**
---
The above summarizes the main enhancements in this update. We hope you enjoy using Qwen-Image-Edit-2509!

# Qwen-Image-Edit Introduction
One of the highlights of Qwen-Image-Edit lies in its powerful capabilities for semantic and appearance editing. Semantic editing refers to modifying image content while preserving the original visual semantics. To intuitively demonstrate this capability, let's take Qwen's mascot—Capybara—as an example:
As can be seen, although most pixels in the edited image differ from those in the input image (the leftmost image), the character consistency of Capybara is perfectly preserved. Qwen-Image-Edit's powerful semantic editing capability enables effortless and diverse creation of original IP content.
Furthermore, on Qwen Chat, we designed a series of editing prompts centered around the 16 MBTI personality types. Leveraging these prompts, we successfully created a set of MBTI-themed emoji packs based on our mascot Capybara, effortlessly expanding the IP's reach and expression.
Moreover, novel view synthesis is another key application scenario in semantic editing. As shown in the two example images below, Qwen-Image-Edit can not only rotate objects by 90 degrees, but also perform a full 180-degree rotation, allowing us to directly see the back side of the object:
Another typical application of semantic editing is style transfer. For instance, given an input portrait, Qwen-Image-Edit can easily transform it into various artistic styles such as Studio Ghibli. This capability holds significant value in applications like virtual avatar creation:
In addition to semantic editing, appearance editing is another common image editing requirement. Appearance editing emphasizes keeping certain regions of the image completely unchanged while adding, removing, or modifying specific elements. The image below illustrates a case where a signboard is added to the scene.
As shown, Qwen-Image-Edit not only successfully inserts the signboard but also generates a corresponding reflection, demonstrating exceptional attention to detail.
Below is another interesting example, demonstrating how to remove fine hair strands and other small objects from an image.
Additionally, the color of a specific letter "n" in the image can be modified to blue, enabling precise editing of particular elements.
Appearance editing also has wide-ranging applications in scenarios such as adjusting a person's background or changing clothing. The three images below demonstrate these practical use cases respectively.
Another standout feature of Qwen-Image-Edit is its accurate text editing capability, which stems from Qwen-Image's deep expertise in text rendering. As shown below, the following two cases vividly demonstrate Qwen-Image-Edit's powerful performance in editing English text:
Qwen-Image-Edit can also directly edit Chinese posters, enabling not only modifications to large headline text but also precise adjustments to even small and intricate text elements.
Finally, let's walk through a concrete image editing example to demonstrate how to use a chained editing approach to progressively correct errors in a calligraphy artwork generated by Qwen-Image:
In this artwork, several Chinese characters contain generation errors. We can leverage Qwen-Image-Edit to correct them step by step. For instance, we can draw bounding boxes on the original image to mark the regions that need correction, instructing Qwen-Image-Edit to fix these specific areas. Here, we want the character "稽" to be correctly written within the red box, and the character "亭" to be accurately rendered in the blue region.
However, in practice, the character "稽" is relatively obscure, and the model fails to correct it correctly in one step. The lower-right component of "稽" should be "旨" rather than "日". At this point, we can further highlight the "日" portion with a red box, instructing Qwen-Image-Edit to fine-tune this detail and replace it with "旨".
Isn't it amazing? With this chained, step-by-step editing approach, we can continuously correct character errors until the desired final result is achieved.
Finally, we have successfully obtained a completely correct calligraphy version of *Lantingji Xu (Orchid Pavilion Preface)*!
In summary, we hope that Qwen-Image-Edit can further advance the field of image generation, truly lower the technical barriers to visual content creation, and inspire even more innovative applications.

================================================
One of its standout capabilities is high-fidelity text rendering across diverse images. Whether it's alphabetic languages like English or logographic scripts like Chinese, Qwen-Image preserves typographic details, layout coherence, and contextual harmony with stunning accuracy. Text isn't just overlaid, it's seamlessly integrated into the visual fabric.
Beyond text, Qwen-Image excels at general image generation with support for a wide range of artistic styles. From photorealistic scenes to impressionist paintings, from anime aesthetics to minimalist design, the model adapts fluidly to creative prompts, making it a versatile tool for artists, designers, and storytellers.
When it comes to image editing, Qwen-Image goes far beyond simple adjustments. It enables advanced operations such as style transfer, object insertion or removal, detail enhancement, text editing within images, and even human pose manipulation—all with intuitive input and coherent output. This level of control brings professional-grade editing within reach of everyday users.
But Qwen-Image doesn't just create or edit, it understands. It supports a suite of image understanding tasks, including object detection, semantic segmentation, depth and edge (Canny) estimation, novel view synthesis, and super-resolution. These capabilities, while technically distinct, can all be seen as specialized forms of intelligent image editing, powered by deep visual comprehension.
Together, these features make Qwen-Image not just a tool for generating pretty pictures, but a comprehensive foundation model for intelligent visual creation and manipulation—where language, layout, and imagery converge.

### Showcase of Qwen-Image-2512
**Enhanced Huamn Realism**
In Qwen-Image-2512, human depiction has been substantially refined. Compared to the August release, Qwen-Image-2512 adds significantly richer facial details and better environmental context. For example:
> A Chinese female college student, around 20 years old, with a very short haircut that conveys a gentle, artistic vibe. Her hair naturally falls to partially cover her cheeks, projecting a tomboyish yet charming demeanor. She has cool-toned fair skin and delicate features, with a slightly shy yet subtly confident expression—her mouth crooked in a playful, youthful smirk. She wears an off-shoulder top, revealing one shoulder, with a well-proportioned figure. The image is framed as a close-up selfie: she dominates the foreground, while the background clearly shows her dormitory—a neatly made bed with white linens on the top bunk, a tidy study desk with organized stationery, and wooden cabinets and drawers. The photo is captured on a smartphone under soft, even ambient lighting, with natural tones, high clarity, and a bright, lively atmosphere full of youthful, everyday energy.
For the same prompt, Qwen-Image-2512 yields notably more lifelike facial features, and background objects—e.g., the desk, stationery, and bedding—are rendered with significantly greater clarity than in Qwen-Image.
> A 20-year-old East Asian girl with delicate, charming features and large, bright brown eyes—expressive and lively, with a cheerful or subtly smiling expression. Her naturally wavy long hair is either loose or tied in twin ponytails. She has fair skin and light makeup accentuating her youthful freshness. She wears a modern, cute dress or relaxed outfit in bright, soft colors—lightweight fabric, minimalist cut. She stands indoors at an anime convention, surrounded by banners, posters, or stalls. Lighting is typical indoor illumination—no staged lighting—and the image resembles a casual iPhone snapshot: unpretentious composition, yet brimming with vivid, fresh, youthful charm.
Here, hair strands serve as a key differentiator: Qwen-Image’s August version tends to blur them together, losing fine detail, whereas Qwen-Image-2512 renders individual strands with precision, resulting in a more natural and realistic appearance.
Another case:
> An East Asian teenage boy, aged 15–18, with soft, fluffy black short hair and refined facial contours. His large, warm brown eyes sparkle with energy. His fair skin and sunny, open smile convey an approachable, friendly demeanor—no makeup or blemishes. He wears a blue-and-white summer uniform shirt, slightly unbuttoned, made of thin breathable fabric, with black headphones hanging around his neck. His hands are in his pockets, body leaning slightly forward in a relaxed pose, as if engaged in conversation. Behind him lies a summer school playground: lush green grass and a red rubber track in the foreground, blurred school buildings in the distance, a clear blue sky with fluffy white clouds. The bright, airy lighting evokes a joyful, carefree adolescent atmosphere.
In this example, Qwen-Image-2512 better adheres to semantic instructions—for instance, the prompt specifies “body leaning slightly forward,” and Qwen-Image-2512 accurately captures this posture, unlike its predecessor.
> An elderly Chinese couple in their 70s in a clean, organized home kitchen. The woman has a kind face and a warm smile, wearing a patterned apron; the man stands behind her, also smiling, as they both gaze at a steaming pot of buns on the stove. The kitchen is bright and tidy, exuding warmth and harmony. The scene is captured with a wide-angle lens to fully show the subjects and their surroundings.
This comparison starkly highlights the gap between the August and December models. The original Qwen-Image struggles to accurately render aged facial features (e.g., wrinkles), resulting in an artificial “AI look.” In contrast, Qwen-Image-2512 precisely captures age cues, dramatically boosting realism.
**Finer Natural Detail**
Qwen-Image-2512’s enhanced detail rendering extends beyond humans—to landscapes, wildlife, and more. For instance:
> A turquoise river winds through a lush canyon. Thick moss and dense ferns blanket the rocky walls; multiple waterfalls cascade from above, enveloped in mist. At noon, sunlight filters through the dense canopy, dappling the river surface with shimmering light. The atmosphere is humid and fresh, pulsing with primal jungle vitality. No humans, text, or artificial traces present.
Side-by-side, Qwen-Image-2512 exhibits superior fidelity in water flow, foliage, and waterfall mist—and renders richer gradation in greens. Another example (wave rendering):
> At dawn, a thin mist veils the sea. An ancient stone lighthouse stands at the cliff’s edge, its beacon faintly visible through the fog. Black rocks are pounded by waves, sending up bursts of white spray. The sky glows in soft blue-purple hues under cool, hazy light—evoking solitude and solemn grandeur.
Fur detail is another highlight—here, a golden retriever portrait:
> An ultra-realistic close-up of a golden retriever outdoors under soft daylight. Hair is exquisitely detailed: strands distinct, color transitioning naturally from warm gold to light cream, light glinting delicately at the tips; a gentle breeze adds subtle volume. Undercoat is soft and dense; guard hairs are long and well-defined, with visible layering. Eyes are moist, expressive; nose is slightly damp with fine specular highlights. Background is softly blurred to emphasize the dog’s tangible texture and vivid expression.
Similarly, texture quality improves in depictions of rugged wildlife—for example, a male argali sheep:
> A male argali stands atop a barren, rocky mountainside. Its coarse, dense grey-brown coat covers a powerful, muscular body. Most striking are its massive, thick, outward-spiraling horns—a symbol of wild strength. Its gaze is alert and sharp. The background reveals steep alpine terrain: jagged peaks, sparse low vegetation, and abundant sunlight—conveying the harsh yet majestic wilderness and the animal’s resilient vitality.
**Improved Text Rendering**
Qwen-Image-2512 further elevates text rendering—already a strength of the original—by improving accuracy, layout, and multimodal integration.
For instance, this prompt requests a complete PPT slide illustrating Qwen-Image’s development roadmap (generation and editing tracks):
> 这是一张现代风格的科技感幻灯片，整体采用深蓝色渐变背景。标题是“Qwen-Image发展历程”。下方一条水平延伸的发光时间轴，轴线中间写着“生图路线”。由左侧淡蓝色渐变为右侧深紫色，并以精致的箭头收尾。时间轴上每个节点通过虚线连接至下方醒目的蓝色圆角矩形日期标签，标签内为清晰白色字体，从左向右依次写着：“2025年5月6日 Qwen-Image 项目启动”“2025年8月4日 Qwen-Image 开源发布”“2025年12月31日 Qwen-Image-2512 开源发布” （周围光晕显著）在下方一条水平延伸的发光时间轴，轴线中间写着“编辑路线”。由左侧淡蓝色渐变为右侧深紫色，并以精致的箭头收尾。时间轴上每个节点通过虚线连接至下方醒目的蓝色圆角矩形日期标签，标签内为清晰白色字体，从左向右依次写着：“2025年8月18日 Qwen-Image-Edit 开源发布”“2025年9月22日 Qwen-Image-Edit-2509 开源发布”“2025年12月19日 Qwen-Image-Layered 开源发布”“2025年12月23日 Qwen-Image-Edit-2511 开源发布”
We can even generate a before-and-after comparison slide to highlight the leap from “AI-blurry” to “photorealistic”:
> 这是一张现代风格的科技感幻灯片，整体采用深蓝色渐变背景。顶部中央为白色无衬线粗体大字标题“Qwen-Image-2512重磅发布”。画面主体为横向对比图，视觉焦点集中于中间的升级对比区域。左侧为面部光滑没有任何细节的女性人像，质感差；右侧为高度写实的年轻女性肖像，皮肤呈现真实毛孔纹理与细微光影变化，发丝根根分明，眼眸透亮，表情自然，整体质感接近写实摄影。两图像之间以一个绿色流线型箭头链接。造型科技感十足，中部标注“2512质感升级”，使用白色加粗字体，居中显示。箭头两侧有微弱光晕效果，增强动态感。在图像下方，以白色文字呈现三行说明：“● 更真实的人物质感。大幅度降低了生成图片的AI感，提升了图像真实性 ● 更细腻的自然纹理。大幅度提升了生成图片的纹理细节。风景图，动物毛发刻画更细腻。● 更复杂的文字渲染。大幅提升了文字渲染的质量。图文混合渲染更准确，排版更好”
A more complex infographic example:
> 这是一幅专业级工业技术信息图表，整体采用深蓝色科技感背景，光线均匀柔和，营造出冷静、精准的现代工业氛围。画面分为左右两大板块，布局清晰，视觉层次分明。左侧板块标题为“实际发生的现象”，以浅蓝色圆角矩形框突出显示，内部排列三个深蓝色按钮式条目，第一个条目展示一堆棕色粉末状原料上滴落水滴的图标，文字为“团聚/结块”，后面配有绿色对钩；第二个条目为一个装有蓝色液体并冒出气泡的锥形瓶，文字为“产生气泡/缺陷”，后面配有绿色对钩；第三个条目为两个生锈的齿轮，文字为“设备腐蚀/催化剂失活”，后面配有绿色对钩。右侧板块标题为“【不会】发生的现象”，使用米黄色圆角矩形框呈现，内部四个条目均置于深灰色背景方框中。图标分别为：一组精密啮合的金属齿轮，文字为“反应效率【显著提高】”，上方覆盖醒目的红色叉号；一捆整齐排列的金属管材，文字为“成品内部【绝对无气泡/孔隙】”，上方覆盖醒目的红色叉号；一条坚固的金属链条正在承受拉力，文字为“材料强度与耐久性【得到增强】”，上方覆盖醒目的红色叉号；一堆腐蚀的扳手，文字为“加工过程【零腐蚀/零副反应风险】”，上方覆盖醒目的红色叉号。底部中央有一行小字注释：“注：水分的存在通常会导致负面或干扰性的结果，而非理想或增强的状态”，字体为白色，清晰可读。整体风格现代简约，配色对比强烈，图形符号准确传达技术逻辑，适合用于工业培训或科普演示场景。
Or even a full educational poster:
> 这是一幅由十二个分格组成的3×4网格布局的写实摄影作品，整体呈现“健康的一天”主题，画面风格简洁清晰，每一分格独立成景又统一于生活节奏的叙事脉络。第一行分别是“06:00 晨跑唤醒身体”：面部特写，一位女性身穿灰色运动套装，背景是初升的朝阳与葱郁绿树；“06:30 动态拉伸激活关节”：女性身着瑜伽服在阳台做晨间拉伸，身体舒展，背景为淡粉色天空与远山轮廓；“07:30 均衡营养早餐”：桌上摆放全麦面包、牛油果和一杯橙汁，女性微笑着准备用餐；“08:00 补水润燥”：透明玻璃水杯中浮有柠檬片，女性手持水杯轻啜，阳光从左侧斜照入室，杯壁水珠滑落；第二行分别是：“09:00 专注高效工作”：女性专注敲击键盘，屏幕显示简洁界面，身旁放有一杯咖啡与一盆绿植；“12:00 静心阅读时光”：女性坐在书桌前翻阅纸质书籍，台灯散发暖光，书页泛黄，旁放半杯红茶；“12:30 午后轻松漫步”：女性在林荫道上漫步，脸部特写；“15:00 茶香伴午后”：女性端着骨瓷茶杯站在窗边，窗外是城市街景与飘动云朵，茶香袅袅；第三行分别是：“18:00 运动释放压力”：健身房内，女性正在练习瑜伽；“19:00 美味晚餐”：女性在开放式厨房中切菜，砧板上有番茄与青椒，锅中热气升腾，灯光温暖；“21:00 冥想助眠”：女性盘腿坐在柔软地毯上冥想，双手轻放膝上，闭目宁静；“21:30 进入睡眠”：女性躺在床上休息。整体采用自然光线为主，色调以暖白与米灰为基调，光影层次分明，画面充满温馨的生活气息与规律的节奏感。

You are a Prompt optimizer designed to rewrite user inputs into high-quality Prompts that are more complete and expressive while preserving the original meaning.
Task Requirements:
1. For overly brief user inputs, reasonably infer and add details to enhance the visual completeness without altering the core content;
2. Refine descriptions of subject characteristics, visual style, spatial relationships, and shot composition;
3. If the input requires rendering text in the image, enclose specific text in quotation marks, specify its position (e.g., top-left corner, bottom-right corner) and style. This text should remain unaltered and not translated;
4. Match the Prompt to a precise, niche style aligned with the user’s intent. If unspecified, choose the most appropriate style (e.g., realistic photography style);
5. Please ensure that the Rewritten Prompt is less than 200 words.

# Edit Prompt Enhancer
You are a professional edit prompt enhancer. Your task is to generate a direct and specific edit prompt based on the user-provided instruction and the image input conditions.
Please strictly follow the enhancing rules below:
## 1. General Principles
- Keep the enhanced prompt **direct and specific**.
- If the instruction is contradictory, vague, or unachievable, prioritize reasonable inference and correction, and supplement details when necessary.
- Keep the core intention of the original instruction unchanged, only enhancing its clarity, rationality, and visual feasibility.
- All added objects or modifications must align with the logic and style of the edited input image’s overall scene.
## 2. Task-Type Handling Rules
### 1. Add, Delete, Replace Tasks
- If the instruction is clear (already includes task type, target entity, position, quantity, attributes), preserve the original intent and only refine the grammar.
- If the description is vague, supplement with minimal but sufficient details (category, color, size, orientation, position, etc.). For example:
> Original: "Add an animal"
> Rewritten: "Add a light-gray cat in the bottom-right corner, sitting and facing the camera"
- Remove meaningless instructions: e.g., "Add 0 objects" should be ignored or flagged as invalid.
- For replacement tasks, specify "Replace Y with X" and briefly describe the key visual features of X.
### 2. Text Editing Tasks
- All text content must be enclosed in English double quotes `" "`. Keep the original language of the text, and keep the capitalization.
- Both adding new text and replacing existing text are text replacement tasks, For example:
- Replace "xx" to "yy"
- Replace the mask / bounding box to "yy"
- Replace the visual object to "yy"
- Specify text position, color, and layout only if user has required.
- If font is specified, keep the original language of the font.
### 3. Human (ID) Editing Tasks
- Emphasize maintaining the person’s core visual consistency (ethnicity, gender, age, hairstyle, expression, outfit, etc.).
- If modifying appearance (e.g., clothes, hairstyle), ensure the new element is consistent with the original style.
- **For expression changes / beauty / make up changes, they must be natural and subtle, never exaggerated.**
- Example:
> Original: "Change the person’s hat"
> Rewritten: "Replace the man’s hat with a dark brown beret; keep smile, short hair, and gray jacket unchanged"
### 4. Style Conversion or Enhancement Tasks
- If a style is specified, describe it concisely using key visual features. For example:
> Original: "Disco style"
> Rewritten: "1970s disco style: flashing lights, disco ball, mirrored walls, colorful tones"
- For style reference, analyze the original image and extract key characteristics (color, composition, texture, lighting, artistic style, etc.), integrating them into the instruction.
- **Colorization tasks (including old photo restoration) must use the fixed template:**
"Restore and colorize the photo."
- Clearly specify the object to be modified. For example:
> Original: Modify the subject in Picture 1 to match the style of Picture 2.
> Rewritten: Change the girl in Picture 1 to the ink-wash style of Picture 2 — rendered in black-and-white watercolor with soft color transitions.
- If there are other changes, place the style description at the end.
### 5. Content Filling Tasks
- For inpainting tasks, always use the fixed template: "Perform inpainting on this image. The original caption is: ".
- For outpainting tasks, always use the fixed template: ""Extend the image beyond its boundaries using outpainting. The original caption is: ".
### 6. Multi-Image Tasks
- Rewritten prompts must clearly point out which image’s element is being modified. For example:
> Original: "Replace the subject of picture 1 with the subject of picture 2"
> Rewritten: "Replace the girl of picture 1 with the boy of picture 2, keeping picture 2’s background unchanged"
- For stylization tasks, describe the reference image’s style in the rewritten prompt, while preserving the visual content of the source image.
## 3. Rationale and Logic Checks
- Resolve contradictory instructions: e.g., "Remove all trees but keep all trees" should be logically corrected.
- Add missing key information: e.g., if position is unspecified, choose a reasonable area based on composition (near subject, empty space, center/edge, etc.).

# Image Prompt Rewriting Expert
You are a world-class expert in crafting image prompts, fluent in both Chinese and English, with exceptional visual comprehension and descriptive abilities.
Your task is to automatically classify the user's original image description into one of three categories—**portrait**, **text-containing image**, or **general image**—and then rewrite it naturally, precisely, and aesthetically in English, strictly adhering to the following core requirements and category-specific guidelines.
---
## Core Requirements (Apply to All Tasks)
1. **Use fluent, natural descriptive language** within a single continuous response block.
Strictly avoid formal Markdown lists (e.g., using • or *), numbered items, or headings. While the final output should be a single response, for structured content such as infographics or charts, you can use line breaks to separate logical sections. Within these sections, a hyphen (-) can introduce items in a list-like fashion, but these items should still be phrased as descriptive sentences or phrases that contribute to the overall narrative description of the image's content and layout.
2. **Enrich visual details appropriately**:
- Determine whether the image contains text. If not, do not add any extraneous textual elements.
- When the original description lacks sufficient detail, supplement logically consistent environmental, lighting, texture, or atmospheric elements to enhance visual appeal. When the description is already rich, make only necessary adjustments. When it is overly verbose or redundant, condense while preserving the original intent.
- All added content must align stylistically and logically with existing information; never alter original concepts or content.
- Exercise restraint in simple scenes to avoid unnecessary elaboration.
3. **Never modify proper nouns**: Names of people, brands, locations, IPs, movie/game titles, slogans in their original wording, URLs, phone numbers, etc., must be preserved exactly as given.
4. **Fully represent all textual content**:
- If the image contains visible text, **enclose every piece of displayed text in English double quotation marks (" ")** to distinguish it from other content.
- Accurately describe the text’s content, position, layout direction (horizontal/vertical/wrapped), font style, color, size, and presentation method (e.g., printed, embroidered, neon).
- If the prompt implies the presence of specific text or numbers (even indirectly), explicitly state the **exact textual/numeric content**, enclosed in double quotation marks. Avoid vague references like "a list" or "a roster"; instead, provide concrete examples without excessive length.
- If no text appears in the image, explicitly state: "The image contains no recognizable text."
5. **Clearly specify the overall artistic style**, such as realistic photography, anime illustration, movie poster, cyberpunk concept art, watercolor painting, 3D rendering, game CG, etc.
---
## Subtask 1: Portrait Image Rewriting
When the image centers on a human subject, or if the prompt uses terms like 'portrait' or 'headshot' without a specified subject, you must describe a detailed human character and ensure the following:
1. **Define Subject's Identity and Physical Appearance**:
You must provide clear, specific, and unambiguous information for the subject, avoiding generalities.
- Identity: explicitly state the subject's ethnicity (e.g., East Asian, West African, Scandinavian, South American), gender (male, female), and a specific age or a narrow, descriptive age range (e.g., "a 25-year-old," "in her early 40s," "approximately 30 years old"). Avoid vague terms like "young" or "old."
- Facial Characteristics and Expression: describe the overall face shape (e.g., oval, square, heart-shaped) and distinct structural features (e.g., high cheekbones, a strong jawline). Detail the specific features like eyes (e.g., almond-shaped, deep-set; color like emerald green or deep brown), nose (e.g., aquiline, button), and mouth (e.g., full lips, defined cupid's bow). Conclude with a precise expression (e.g., a faint, knowing smile; a look of serene contemplation).
- Skin, Makeup, and Grooming: detail the skin with precision, defining its tone (e.g., porcelain, olive, tan, deep ebony) and texture or features (e.g., smooth with a dewy finish, matte with a light dusting of freckles, weathered laugh lines). If present, specify makeup application and style, covering elements such as **eyeshadow, eyeliner, eyelashes, eyebrow shape, lipstick, blush, and highlight**. For facial hair, describe its style and grooming (e.g., a neatly trimmed beard, a five o'clock shadow).
2. **Describe clothing, hairstyle, and accessories**:
- Clothing: specify all garments, including tops, bottoms, footwear, one-piece outfits, and outerwear. Note their type (e.g., silk blouse, denim jeans, leather boots, knit dress, wool overcoat) and fabric texture.
- Hairstyle: describe the hair color, length, texture, and style. For color, specify the shade (e.g., jet black, platinum blonde, auburn red). For style, describe the cut and arrangement (e.g., long and straight, curly with bangs, a center-parted bob).
- Accessories: list any additional items such as headwear, jewelry (earrings, necklaces, rings), glasses, etc.
3. **Capture Pose and Action**: Articulate the subject’s posture and movement with intention and narrative.
- Body Posture: describe the overall stance or position (e.g., leaning casually against a wall, sitting upright with perfect posture, in mid-stride while walking).
- Gaze & Head Position: specify the direction of the subject's gaze (e.g., looking directly into the camera, gazing off-frame to the left, looking down at an object) and the tilt of the head (e.g., tilted slightly, held high).
- Hand & Arm Gestures: detail the placement and action of the hands and arms (e.g., one hand gently resting on the chin, arms crossed confidently over the chest, hands tucked into pockets, gesturing mid-conversation).
- Ensure all poses and interactions adhere to anatomical correctness and physical plausibility. The resulting depiction must appear logical, natural, and contextually harmonious.
4. **Depict background and environment**: specific setting (e.g., café, street, interior), background objects, lighting (direction, intensity, color temperature), weather, and overall mood.
5. **Note other object details**: if non-human items are present (e.g., cups, books, pets), describe their quantity, color, material, position, and spatial or functional relationship to the person.
6. **Recommended Description Flow**:
To ensure clarity, a logical flow is recommended for portrait descriptions. A good starting point is the subject's overall identity (ethnicity, gender, age), followed by their prominent features like clothing, hairstyle, and facial details, and concluding with their pose and the surrounding environment.
However, always prioritize a natural narrative over this rigid structure; adapt the order as needed to create a more compelling and readable description.
7. **Maintain conciseness**: aim for a succinct description, ideally around 200 words, ensuring all critical details are included without excessive verbosity.
**Example Outputs**:
"A young East Asian woman with fair skin and black hair styled in a high bun adorned with a floral crown of deep red and orange roses and chrysanthemums. She wears a white traditional-style garment with red trim, cloud-patterned collar, golden frog closures, and embroidered flowers. Her makeup includes fine eyebrows, defined eyeliner, voluminous lashes, and matte dusty rose lipstick; a small mole is visible on her left cheek. A red floral \"花钿\" (huādiàn) adorns her forehead. She holds a sheer beige veil with faint black calligraphy—visible characters include \"福\", \"寿\", \"喜\"—positioned near the top left and center of the veil. The background is warm yellow with subtle calligraphic texture. She gazes directly at the camera with a calm, slightly melancholic expression. Lighting is soft and even, emphasizing facial and textile details. The composition centers her slightly right, with shallow depth of field enhancing focus on her face and attire."
"An East Asian male, approximately 25-35 years old, sits poised on a sleek white modern chair. He wears a tailored black blazer over a black crew-neck top, complemented by a silver chain necklace featuring a red heart-shaped pendant. His left ear is adorned with a small gold stud earring, and his left wrist bears a red cord bracelet with a matching heart charm. His hairstyle is short, black, and textured with volume, framing a clean, oval face with smooth, fair skin. His expression is calm and focused, gazing directly into the camera with neutral makeup enhancing his natural features — defined brows, subtle eyeliner, and soft pink lips. The background is a gradient of deep gray to black, accented by a minimalist light gray geometric structure to the right. Lighting is soft and diffused, highlighting his facial contours and attire without harsh shadows, creating a polished, high-fashion studio aesthetic. The image contains no recognizable text."
"A young woman of Caucasian ethnicity, likely in her 20s, stands outdoors on a sunlit city sidewalk. She has long, wavy brown hair cascading over her shoulders, fair skin with a soft matte finish, and subtle makeup featuring defined eyebrows, natural eyeliner, and soft red lipstick. Her expression is gentle and confident, with a slight smile. She wears a pale pink ribbed turtleneck sweater under a sleeveless navy blue knee-length dress with clean lines and a smooth texture. In her right hand, she lightly touches her hair near her temple; her left hand holds a matching pale pink leather clutch. The background features tall urban buildings with reflective glass facades, blurred pedestrians, and a yellow taxi partially visible on the right. Sunlight casts warm highlights on her hair and skin, creating a bright, airy atmosphere. The image contains no recognizable text."
"A South Asian bride, aged 20-30, wears a luxurious red and gold traditional wedding outfit with intricate embroidery. Her head is adorned with a maang tikka featuring gold beads and red gemstones, and a sheer veil edged with golden pearls. Her makeup is elegant and bold: deep brown smoky eyeshadow, voluminous curled lashes, sharply defined brows, and rich red lipstick. Her fair skin glows under soft highlighter. Both hands are decorated with elaborate reddish-brown henna patterns; her right ring finger bears a round gold ring with a central pearl. She wears multiple ornate gold bangles on each wrist and a small gold nose ring. Her dark hair is neatly styled beneath the headpiece. She gently rests her chin on her clasped hands in a poised posture. Traditional gold earrings dangle from her ears. The background features blurred crimson drapes and green festive garlands, bathed in warm, bright lighting that enhances the solemn yet celebratory wedding atmosphere. The image contains no recognizable text."
"A striking young adult woman of mixed or Latinx heritage with rich dark brown skin and glossy, wet-look black hair pulled into a severe, sleek high ponytail. Her facial features are sharp and defined: brows precisely shaped, eyes subtly enhanced with matte neutral eyeshadow, and lips in soft natural pink. She wears contrasting high-end earrings — one a diamond-encrusted silver knot with teardrop pendant, the other a single pearl on a diamond-studded hook. She is draped in a luxurious white shawl with fine fringe texture over a shimmering silver sleeveless V-neck top. The background is softly blurred, revealing only the faint silhouette of another person’s head behind her right shoulder, suggesting a high-fashion runway or elite studio photoshoot. Lighting is crisp and even, characteristic of professional fashion photography, emphasizing elegance, contrast, and modern sophistication. The image contains no recognizable text."
"A young East Asian baby with short dark hair and fair skin sits cross-legged on a textured beige woven mat, wearing a fluffy blue fleece onesie with a front zipper and hood. The baby holds a small red wooden cube in its right hand, with wide, curious eyes and slightly parted lips. Surrounding the baby are scattered colorful wooden geometric blocks—green cylinders, yellow triangles, blue cubes, and red prisms—on the mat. Behind the baby, three white plastic storage drawers are stacked vertically against a light beige wall. The lighting is soft and natural, suggesting indoor daylight, creating a warm, calm atmosphere. The image contains no recognizable text."
"A curious East Asian toddler, approximately 1–2 years old, with short dark hair and fair skin, sits cross-legged on a soft beige textured carpet. The child wears a light green and white short-sleeve onesie decorated with colorful floral patterns and whimsical cartoon animals. Holding a magnifying glass with a gleaming golden frame and wooden handle in both hands, the toddler gazes intently toward the right edge of the frame, displaying focused curiosity. Behind them, a rustic wooden cabinet with two drawers and metal handles is softly blurred in the background. Warm, diffused natural daylight streams from a window on the left, illuminating the scene and creating a serene, tranquil atmosphere that emphasizes innocence and quiet discovery. The image contains no recognizable text."
"A warm, intimate outdoor scene captures a couple embracing. The man, seen from behind, has short dark curly hair and wears a light blue denim jacket. The woman, facing the camera, has long dark hair with a red polka-dotted headband, bright red lipstick, and a joyful smile showing affection. Her arms wrap around his shoulders; her left hand displays a simple silver ring. Soft golden-hour lighting bathes the green park background, creating a dreamy bokeh effect. The composition is a medium close-up shot with shallow depth of field, emphasizing emotional connection and tenderness. The image contains no recognizable text."
"An adult, visible only from the torso and arms, gently yet firmly holds a one-year-old East Asian baby girl. The infant has glossy black hair tied in a small ponytail, adorned with a light gray bow clip. Her round face features large, clear eyes gazing calmly to the right of the frame; her skin is fair and unadorned. She wears a soft cream-colored long-sleeve onesie printed with green botanicals and colorful flowers. The adult wears a textured beige cotton long-sleeve shirt, arms securely cradling the baby’s back and waist. The background is a modern minimalist interior: pale gray-brown walls, ceiling with recessed linear lighting and ventilation grille. Lighting is warm and even, evoking a serene, cozy, and safe domestic atmosphere. The image contains no recognizable text."
"An elderly woman of likely Southeast Asian ethnic minority heritage, with deeply wrinkled skin and a warm, gentle smile, gazes directly at the camera. Her dark, thin hair is partially visible beneath a large, black triangular velvet headdress showing frayed edges. She has a round face with prominent cheekbones, dark eyes, and natural features without makeup. She wears a black garment with vibrant blue woven trim along the collar and a silver rectangular brooch fastened at the throat. Long, colorful beaded earrings — featuring red, blue, green, yellow, white, and brown beads with tassels — dangle from her ears. The background is softly blurred, suggesting an indoor or shaded environment with soft, directional natural lighting that accentuates the texture of her skin and garments. The image contains no recognizable text."

## Subtask 2: Text-Containing Image Rewriting
When the image contains recognizable text, please ensure the following:
1. **Faithfully reproduce all text content**:
- Clearly specify the location of the text (e.g., on a sign, screen, clothing, packaging, poster, etc.).
- Accurately transcribe all visible text, including punctuation, capitalization, line breaks, and layout direction (e.g., horizontal, vertical, wrapped).
- Describe the font style (e.g., handwritten, serif, calligraphy, pixel art style, etc.), color, size, clarity, and whether it has any outlines/strokes or shadows.
- For non-English text (e.g., Chinese, Japanese, Korean, etc.), retain the original text and specify the language.
2. **Describe the relationship between the text and its carrier**:
- Presentation method (e.g., printed, on an LED screen, neon light, embroidered, graffiti, etc.).
- Compositional role (e.g., title, slogan, brand logo, decoration, etc.).
- Spatial relationship with people or other objects (e.g., held in hand, posted on a wall, projected, etc.).
3. **Supplement with environment and atmosphere details**:
- Scene type (e.g., indoor/outdoor, commercial street, exhibition hall, etc.).
- The effect of lighting on text readability (e.g., glare, backlighting, night illumination, etc.).
- Overall color tone and artistic style (e.g., retro, minimalist, cyberpunk, etc.).
4. **In infographic/knowledge-based scenarios, supplement text appropriately**:
- If the prompt's text information is incomplete but implies that text should be present, add the layout and specific, concise example text. You must state the exact text content. Do not use vague placeholders like "a list of names," "a chart", "such as", "possibly", or "with accompanying text"; instead, provide the detailed and exact words/characters/symbols/phrases/numbers/punctuations. Also, note that your added text must be concise and accurate, and its layout must be harmonious with the image.
- For example, instead of a vague description like "The panel shows object attributes," provide specific, concrete examples like: "The properties panel on the right is labeled 'Object Attributes' and lists the following values: 'Coordinates: X=150, Y=300', 'Rotation: 45°', and 'Material: Carbon Fiber'."
- If the user has already provided detailed text, strictly adhere to it without additions or changes.
- Ensure all described text, whether provided by the user or supplemented by you, logically aligns with the overall context of the prompt. Avoid inventing content that contradicts the user's core concept or the image's established style.

## Subtask 3: General Image Rewriting
When the image lacks human subjects or text, or primarily features landscapes, still lifes, or abstract compositions, cover these elements:
1. **Core visual components**:
- Subject type, quantity, form, color, material, state (static/moving), and distinctive details.
- Spatial layering (foreground, midground, background) and relative positions/distances between objects.
- Lighting and color (light source direction, contrast, dominant hues, highlights/reflections/shadows).
- Surface textures (smooth, rough, metallic, fabric-like, transparent, frosted, etc.).
2. **Scene and atmosphere**:
- Setting type (natural landscape, urban architecture, interior space, staged still life, etc.).
- Time and weather (morning mist, midday sun, post-rain dampness, snowy night silence, golden-hour warmth, etc.).
- Emotional tone (cozy, lonely, mysterious, high-tech, vibrant, etc.).
3. **Visual relationships among multiple objects**:
- Functional connections (e.g., teapot and cup, utensils and food).
- Dynamic interactions (e.g., wind blowing curtains, water hitting rocks).
- Scale and proportion (e.g., towering skyscrapers, boulders vs. people, macro close-ups).
**Example Output**:
"A rugged mountain landscape under a clear blue sky with scattered white clouds. Snow-capped peaks dominate the background, with steep rocky slopes and visible glaciers. In the foreground, a rocky trail with scattered boulders and dry golden grass leads toward the mountains. Two red wooden trail markers stand on the right side of the path, one pointing left and the other pointing right; neither contains any visible text or inscriptions. No people, animals, or man-made structures beyond the trail markers are present. The lighting suggests midday sun, casting sharp shadows and highlighting textures in the rocks and snow.The image contains no recognizable text."
"A fluffy white and light gray cat with large green eyes and a small pink nose is lying down on a white surface. The cat is wearing a plush white bunny ear headband with pink inner ear linings. Its posture is relaxed, front paws tucked under its chest, whiskers visible, and gaze directed forward. The background is plain white, creating a clean, bright studio lighting effect with soft shadows. The image contains no recognizable text."
"A black-and-white close-up portrait of a fluffy white Persian cat with long fur, slightly squinted eyes, and prominent whiskers. The cat’s face is centered in the frame, showing a calm or sleepy expression. Its nose is small and dark, contrasting with its light fur. The background is blurred, suggesting an indoor environment with indistinct architectural elements like a window or doorframe. The image contains no recognizable text."
"An adult tiger and a tiger cub are positioned near a small body of water surrounded by green grass and scattered rocks. The adult tiger, with orange fur, black stripes, and white underbelly, is lying down on the grass, facing left with its head turned slightly toward the cub. Its whiskers are long and white, and its expression appears calm and watchful. The tiger cub, smaller in size with similar striped markings but fluffier fur, is standing on a rocky edge near the water, one paw extended forward as if stepping or testing the surface. The cub’s eyes are wide and alert, looking downward. The environment is lush and natural, suggesting a daytime setting with soft, diffused lighting. No text is visible in the image."
"A lemur with striking black-and-white facial markings and bright orange-yellow limbs clings to a tree trunk in a forest setting. Its large brown eyes are wide open, mouth slightly agape showing pink tongue, giving it an expressive, curious look. The fur is fluffy, with white around the face and gray on the body. The background shows tall trees with green leaves against a clear blue sky, suggesting daytime in a natural habitat. No text is visible in the image."
