1:1 aspect ratio (1:1)
The square is the neutral default of image generation: no orientation bias, equal composition weight in every direction, and the widest model support.
Standard pixel sizes
| Size string | Resolution | Megapixels |

1:1 FAQ
What resolution is 1:1?
1:1 is a ratio, not a fixed resolution — any pixel dimensions where width ÷ height = 1 ÷ 1 is "1:1". Common generation sizes include 1024×1024, 2048×2048, 4096×4096, listed in the table above.
Which AI models generate 1:1 images?
On our gateway, GPT Image 2, GPT Image 2.5 Flare, GPT Image 2.5 Sunburst, Qwen Image 2.1 (Unrestricted), Seedream 5 Pro (Unrestricted), NovelAI V5 (Unrestricted), NovelAI V4.5 (Unrestricted), GPT Image 2 HD, Nano Banana 2.1, Nano Banana 3 Pro, Nano Banana 3.1 Flash, Grok Image 2.0, Seedream 5 Pro, Qwen Image 2.0, Qwen Image 2.0 Pro, Qwen Image 3.0, Qwen Image 3.0 Pro, Wan 2.7 Image, Kling 3.0 Image, Z-Image Turbo support 1:1 natively for image generation. Pass the size string (e.g. "1024×1024") in your API request.
Which AI video models output 1:1?
Video models output 16:9 or 9:16; 1:1 is an image-only ratio on our gateway.
How much does a 1:1 generation cost?
Aspect ratio doesn't affect price — image models bill per generated image (from $0.025) and video models per clip. See the pricing page for live rates.
