## Resolution

`resolution` selects the output pixel tier while `aspect_ratio` controls its shape. Use `1K` for faster generation or `2K` for maximum detail. Qwen Image 3.0 Pro output pricing varies by tier, and each input/reference image is billed separately.

| Aspect ratio | 1K dimensions | 2K dimensions |
| ------------ | ------------- | ------------- |
| `1:1`        | 1024×1024     | 2048×2048     |
| `16:9`       | 1344×768      | 2688×1536     |
| `9:16`       | 768×1344      | 1536×2688     |
| `4:3`        | 1184×864      | 2368×1728     |
| `3:4`        | 864×1184      | 1728×2368     |
| `3:2`        | 1248×832      | 2496×1664     |
| `2:3`        | 832×1248      | 1664×2496     |
