GPT-Image-2
GPT-Image-2 Image Generation
- Asynchronous processing mode, returns a task ID for subsequent queries
- Compatible with OpenAI Images protocol, supports text-to-image / image-to-image
- Supports 13 image aspect ratios, passed through the aspect_ratio field
- Added resolution tier field, supports 1K / 2K / 4K resolution selection (4K full aspect ratio supported)
- Added size field, supports custom pixel dimensions (mutually exclusive with aspect_ratio / resolution, total pixels ≥ 2,088,960 required for precise generation)
- Up to 10 reference images, supports mixed URL and base64 inputs
- Submitted prompts will undergo platform sensitive word / security review, violating content will be directly rejected

Image Generation Aspect RatioDefault value varies with
resolution:- Defaults to
autowhenresolutionis1K/2K - Defaults to
16:9whenresolutionis4K
auto- Automatically selects the most suitable ratio1:1- Square16:9/9:16- Wide horizontal / vertical4:3/3:4- Standard horizontal / vertical3:2/2:3- Classic horizontal / vertical5:4/4:5- Nearly square horizontal / vertical2:1/1:2- Wide horizontal / tall vertical21:9/9:21- Ultra-wide horizontal / ultra-tall vertical
Only aspect ratio strings or
auto are supported; passing pixel dimensions (e.g., 1024x1024) will cause an errorResolution TierControls the actual output image clarity:
1K- 1024 baseline, cost-effective for daily use (default)2K- 2048 baseline, suitable for posters / high-definition needs4K- 3840 baseline, supports all 13 ratios
When passing
size, resolution and aspect_ratio cannot be passed at the same time; otherwise, a 400 error will be returned.Custom Pixel Dimensions (mutually exclusive with
Recommendations:
aspect_ratio / resolution)Format is widthxheight, e.g., 2048x1536, 3840x2160.Usage Limitations:- Format must match

aspect_ratioandresolution; only one of the three can be chosen; passing both will return 400 - Total pixels (width × height) must be within 655,360 ~ 8,294,400
| Total Pixel Range | Upstream Behavior |
|---|---|
| ≥ 2,088,960 (approx. 2.0M) | Exact output according to the passed size ✅ |
| < 2,088,960 | Silently replaced with a similar ratio (~1.57M) (equivalent to not passing size) ⚠️ |
When total pixels are below approximately 2,088,960, upstream does not report an error but silently replaces output size. For precise control, it is recommended to have total pixels ≥ 2,088,960.For small size needs, please use the combination of
aspect_ratio + resolution=1K.| Requirement | Recommended Method |
|---|---|
| Precise pixel size control | size with total pixels ≥ 2,088,960 |
| Small size (< 2M pixels) | aspect_ratio + resolution=1K |
| Medium to large sizes with any ratio | size; 2K / 4K range supports precise output for any ratio |

Custom Size (size parameter)
When you need precise control over pixel dimensions, use thesize parameter instead of the aspect_ratio + resolution combination.
Valid range: Total pixels 655,360 ~ 8,294,400 (upstream official limit)
Tested effective lower limit: Total pixels ≥ 2,088,960 (approximately 1440×1452 or 2048×1020 equivalent area)
Below this lower limit, the upstream does not report an error but silently replaces it with a close proportion size of about 1.57M pixels.
Common size examples
| size value | Total pixels | Recommended use |
|---|---|---|
2048x2048 | 4,194,304 | Square HD |
2048x1536 | 3,145,728 | 4:3 landscape |
1536x2048 | 3,145,728 | 3:4 portrait |
2048x1152 | 2,359,296 | 16:9 landscape |
1152x2048 | 2,359,296 | 9:16 portrait |
3840x2160 | 8,294,400 | 4K 16:9 (highest quality) |
