DashScope (阿里通义万象)
Read when the user picks --provider dashscope, sets default_model.dashscope, or asks for Qwen-Image behavior. The SKILL.md only names the default — this file covers model families, sizing rules, and limits.
Model Families
qwen-image-2.0* — recommended modern family. Members: qwen-image-2.0-pro, qwen-image-2.0-pro-2026-03-03, qwen-image-2.0, qwen-image-2.0-2026-03-03.
- Free-form
sizein宽*高format - Total pixels must be between
512*512and2048*2048 - Default ≈
1024*1024 - Best choice for custom ratios (e.g.
21:9) and text-heavy Chinese/English layouts
Fixed-size family — qwen-image-max, qwen-image-max-2025-12-30, qwen-image-plus, qwen-image-plus-2026-01-09, qwen-image.
- Only five sizes allowed:
1664*928,1472*1104,1328*1328,1104*1472,928*1664 - Default is
1664*928 qwen-imagecurrently has the same capability asqwen-image-plus
Legacy — z-image-turbo, z-image-ultra, wanx-v1. Only use when the user explicitly asks for legacy behavior.

Not Exposed
DashScope APIs also support negative_prompt, prompt_extend, and watermark, but baoyu-imagine does not expose them as CLI flags today.
