Key features and benefits
Quality and style
Qwen Image 3 Pro targets premium photorealism and refined artistic output from natural-language prompts. It excels at detailed scenes, precise text rendering, and coherent multi-image generation for story-driven shorts.
Aspect ratios
Supported aspect ratios include 1:1, 1:2, 1:4, 2:1, 2:3, 3:2, 3:4, 4:1, 4:3, 4:5, 5:4, 9:16, and 16:9. VidMachine defaults to 9:16 for shorts and start frames so generated assets align with vertical delivery formats.
Reference images
When your project or scene pipeline provides reference URLs—such as a project hero image or the previous segment's starting frame—VidMachine sends up to 4 references so the model can use visual context alongside your text prompt.
OpenRouter routing
On VidMachine this model runs only through OpenRouter's dedicated Images API (POST /api/v1/images), not Replicate. You need OPENROUTER_API_KEY configured in the environment; billing uses VidMachine credits per image.
