Supported Resolutions
Output width and height of the v2 API for each of the 11 aspect ratios at the 1k and 1.5k size tiers, plus the defaults.
The v2 API uses aspectRatio + size to determine the output resolution. All dimensions are divisible by 16 as required by diffusion backends.
| Aspect Ratio | 1k (Width × Height) | 1.5k (Width × Height) |
|---|---|---|
| 1:1 | 1024 × 1024 | 1536 × 1536 |
| 2:3 | 848 × 1280 | 1024 × 1536 |
| 3:2 | 1280 × 848 | 1536 × 1024 |
| 3:4 | 864 × 1152 | 1152 × 1536 |
| 4:3 | 1152 × 864 | 1536 × 1152 |
| 3:5 | 768 × 1280 | 912 × 1536 |
| 5:3 | 1280 × 768 | 1536 × 912 |
| 9:16 | 720 × 1280 | 864 × 1536 |
| 16:9 | 1280 × 720 | 1536 × 864 |
| 1:3 | 512 × 1536 | 512 × 1536 |
| 3:1 | 1536 × 512 | 1536 × 512 |
- Default:
aspectRatio: "1:1",size: "1k"→ 1024 × 1024. 1.5kcaps the longest edge at 1536 px. For extreme ratios (1:3, 3:1) the dimensions are identical to 1k.- All aspect ratios are available across all model types (SDXL, DiT, Tsubaki.2).
