Qwen Image Generation

Generate and edit images using Wan and Qwen Image models. Supports text-to-image, reference-image editing (style transfer, subject consistency, multi-image composition, text rendering), and interleaved text-image output. This skill is part of QianWen-AI/qianwen-ai.

Skill directory

Use this skill's internal files to execute and learn. Load reference files on demand when the default path fails or you need details.

| Location | Purpose | |----------|---------| | scripts/image.py | Default execution — sync/async, upload, download | | references/execution-guide.md | Fallback: curl (sync/async), code generation | | references/prompt-guide.md | Prompt formulas, style keywords, negative_prompt, prompt_extend decision | | references/api-guide.md | API supplement | | references/sources.md | Official documentation URLs | | references/agent-compatibility.md | Agent self-check: register skills in project config for agents that don't auto-load |

Security

NEVER output any API key or credential in plaintext. Always use variable references ($DASHSCOPE_API_KEY in shell, os.environ["DASHSCOPE_API_KEY"] in Python). Any check or detection of credentials must be non-plaintext: report only status (e.g. "set" / "not set", "valid" / "invalid"), never the value. Never display contents of .env or config files that may contain secrets.

When the API key is not configured, NEVER ask the user to provide it directly. Instead, help create a .env file with a placeholder (DASHSCOPE_API_KEY=sk-your-key-here) and instruct the user to replace it with their actual key from the QianWen Console. Only write the actual key value if the user explicitly requests it.

Key Compatibility

Scripts require a standard QianWen API key (sk-...). Token Plan 团队版 keys (sk-sp-...) target a different endpoint (token-plan.cn-beijing.maas.aliyuncs.com) and cannot be used by these scripts. Token Plan does include 4 image generation models (qwen-image-2.0, qwen-image-2.0-pro, wan2.7-image, wan2.7-image-pro), but they are accessed only through interactive AI tools' Skill / Slash Command / Agent mechanism against a dedicated multimodal-generation endpoint — not via this skill's standard DashScope flow. Standard sk- key required for this skill. The script detects sk-sp- keys at startup and prints a warning. If qianwen-ops-auth is installed, see its references/tokenplan.md for full details.

Mode Selection Guide

| User Want | Mode | Model | |-----------|------|-------| | Generate image from text only | t2i | wan2.6-t2i (default), or wan2.7-image / wan2.7-image-pro | | Open-source / lowest-cost text-to-image | t2i | z-image-turbo (sync-only; no n; no reference images) | | Edit image / apply style transfer based on 1–4 reference images | image-edit | wan2.7-image-pro / wan2.7-image / wan2.6-image | | Subject consistency: generate new images maintaining subject from references | image-edit | wan2.7-image-pro / wan2.7-image / wan2.6-image | | Multi-image composition: combine style from one image, background from another | image-edit | wan2.7-image-pro / wan2.7-image / wan2.6-image | | Single-image editing preserving subject consistency | i2i | wan2.5-i2i-preview | | Multi-image fusion: place object from one image into another scene | i2i | wan2.5-i2i-preview | | Interleaved text-image output (e.g., tutorials, step-by-step guides) | interleave | wan2.6-image | | Fast text-to-image drafts | t2i | wan2.2-t2i-flash | | Edit text within images, precise element manipulation | image-edit | qwen-image-2.0-pro | | Multi-image fusion with realistic textures | image-edit | qwen-image-2.0-pro | | Posters / complex Chinese+English text rendering | t2i | qwen-image-2.0-pro | | Text-to-image with fixed aspect ratios (batch) | t2i | qwen-image-plus / qwen-image-max |

Model Selection

Wan Series (default)

| Model | Use Case | |-------|----------| | wan2.6-t2i | Recommended for text-to-image — sync + async, best quality | | wan2.7-image-pro | Multi-function (4K support) — text-to-image, image editing (0–9 images), sequential multi-image, interactive editing (bbox), thinking mode, color palette. Max 4K for t2i, 2K for editing | | wan2.7-image | Multi-function (faster) — same as pro but max 2K, no 4K support | | wan2.6-image | Image editing (NOT for pure text-to-image) — requires reference_images or enable_interleave: true. Style transfer, subject consistency (1–4 images), interleaved text-image output, 2K | | wan2.5-i2i-preview | Image editing — single-image editing with subject consistency, multi-image fusion (up to 3 images), async-only | | wan2.5-t2i-preview | Preview — free size within constraints | | wan2.2-t2i-flash | Fast — lower latency | | wan2.2-t2i-plus | Professional — improved stability |

Other

| Model | Use Case | |-------|----------| | z-image-turbo | Open-source SOTA T2I — sync-only; single text content per message; no n parameter (server returns 400 if provided); no reference images. Parameters: size, prompt_extend, seed. |

Qwen Image Series

| Model | Use Case | |-------|----------| | qwen-image-2.0-pro | Fused generation + editing — text rendering, realistic textures, multi-image (1–3 input, 1–6 output) | | qwen-image-2.0 | Accelerated generation + editing | | qwen-image-edit-max | Image editing — 1–6 output images | | qwen-image-edit-plus | Image editing — 1–6 output images | | qwen-image-edit | Image editing — 1 output image only | | qwen-image-plus | Text-to-image — fixed resolutions only (async) | | qwen-image-max | Text-to-image — fixed resolutions only |

Qwen Image editing models (qwen-image-2.0-pro, qwen-image-2.0, qwen-image-edit-max/plus/edit) use the same sync endpoint as wan2.6-image (/multimodal-generation/generation) with messages format. They support text editing in images, element add/delete/replace, style transfer, and multi-image fusion (1–3 input images). Size range: 512x512 to 2048x2048. qwen-image-2.0-pro and qwen-image-2.0 also support pure text-to-image (no reference images needed).

Qwen Image text-to-image models (qwen-image-plus, qwen-image-max) use a different endpoint (/text2image/image-synthesis) with input.prompt format (async-only). They support only 5 fixed resolutions: 1664\928, 1472\1104, 1328\1328, 1104\1472, 928\*1664.

Choosing between wan2.6-image and wan2.5-i2i-preview for image editing:

2. Consult the qianwen-model-selector skill when model choice depends on requirement, scenario, or pricing. 3. Text-to-image (prompt only, no reference images) → use wan2.6-t2i (default) or wan2.7-image / wan2.7-image-pro (multi-function, higher quality). NEVER use wan2.6-image for pure text-to-image — it will error without reference images or enable_interleave: true. 4. Reference images / image editing / interleaved output → wan2.7-image-pro (recommended), wan2.7-image, or wan2.6-image.

⚠️ Important: The model list above is a point-in-time snapshot and may be outdated. Model availability
changes frequently. **Always check the official model list
for the authoritative, up-to-date catalog before making model decisions.**

Model details: For more information about a specific model, direct the user to its detail page: https://www.qianwenai.com/models/ (replace with the exact model ID, e.g. wan2.7-image-pro → https://www.qianwenai.com/models/wan2.7-image-pro). NEVER modify or guess the model name in the URL.

Dynamic model queries: If the qianwen-model-selector skill or QianWen CLI (qianwen models info ) is available, use it for real-time model data. CLI requires authentication — see the qianwen-usage skill for login flow.

Execution

⚠️ Multiple artifacts: When generating multiple files in a single session, you MUST append a numeric suffix to each filename (e.g. out_1.png, out_2.png) to prevent overwrites.

Prerequisites

- API Key: Check that DASHSCOPE_API_KEY (or QIANWEN_API_KEY) is set using a non-plaintext check only (e.g. in shell: -n "$DASHSCOPE_API_KEY" ]; report only "set" or "not set", never the key value). If not set: run the qianwen-ops-auth skill if available; otherwise guide the user to obtain a key from [QianWen Console and set it via .env file (echo 'DASHSCOPE_API_KEY=sk-your-key-here' >> .env in project root or current directory) or environment variable. The script searches for .env in the current working directory and the project root. Skills may be installed independently — do not assume qianwen-ops-auth is present.

If python3 is not found, try python --version or py -3 --version. If Python is unavailable or below 3.9, skip to Path 2 (curl) in execution-guide.md.

Default: Run Script

Script path: Scripts are in the scripts/ subdirectory of this skill's directory (the directory containing this SKILL.md). **You MUST first locate this skill's installation directory, then ALWAYS use the full absolute path to execute scripts.** Do NOT assume scripts are in the current working directory. Do NOT use cd to switch directories before execution.

Execution note: Run all scripts in the foreground — wait for stdout; do not background.

Discovery: Run python3 /scripts/image.py --help first to see all available arguments.

Text-to-image (wan2.6-t2i, default)

python3 /scripts/image.py \
  --request '{"prompt":"A cozy flower shop with wooden door"}' \
  --output output/qianwen-image-generation/images/out.png \
  --print-response
Image editing with reference images (wan2.6-image)

python3 /scripts/image.py \
  --model wan2.6-image \
  --request '{"prompt":"Apply watercolor painting style to this photo","reference_images":["https://img.alicdn.com/imgextra/i1/NotRealJustExample/photo.jpg"],"n":1,"size":"1K"}' \
  --output output/qianwen-image-generation/images/out.png \
  --print-response

Request Fields (wan2.7-image-pro / wan2.7-image — Multi-function)

| Field | Type | Description | |-------|------|-------------| | reference_images | string[] | 0–9 image URLs or local paths | | reference_image | string | Single image URL/path (shorthand) | | size | string | 1K, 2K (default), or 4K (pro only, t2i mode). Or pixel dimensions | | enable_sequential | bool | true: sequential multi-image mode (n=1–12). false (default): single/batch mode (n=1–4) | | n | int | Images to generate. Sequential mode: 1–12 (default 12). Non-sequential: 1–4 (default 4). Billed per image. | | thinking_mode | bool | Enable enhanced reasoning for better quality (default: true). Only for t2i (no images, non-sequential) | | bbox_list | List[List[List[int]]] | Interactive editing regions. Format: [[[x1,y1,x2,y2],...], ...]. List length = image count.

NEVER fabricate, guess, or construct usage/billing/console URLs. Only provide the exact links listed in this skill. If a URL is not listed here, do not invent one.

Output Location

Prefer the current working directory. Default subdirectory: ./output/qianwen-image-generation/.

Write prohibition: NEVER write output files into this skill's installation directory or any skills/ hierarchy. All generated content must go to output/ under the current working directory or a user-specified path.

Update Check (MANDATORY Post-Execution)

After script execution, check stderr for action signals. The script automatically detects update status and emits structured signals. You MUST act on them. This section also applies when the user explicitly asks to check for updates.

Signal: [ACTION_REQUIRED] qianwen-update-check skill is not installed

When stderr contains this signal, you MUST present the following options to the user and wait for their response before proceeding. Do NOT silently skip this.

The update-check skill is not installed. It keeps you informed about new QianWen-AI/qianwen-ai features and bug fixes.
>
1) Install now — I'll run the install command for you
2) Skip for now — do nothing this time
3) Never remind me — permanently suppress this prompt

After the user responds:

1. Look for qianwen-update-check/SKILL.md in sibling skill directories. 2. If found — run: python3 /scripts/check_update.py --print-response and report the result. 3. If not found — present the install options above.
