mai-image-2.6-flash for quick iteration on posters, product shots, and other images from a prompt, or to edit and combine reference images. It accepts the same parameters as MAI Image 2.6 and is faster and lower-cost.
Models
- mai-image-2.6-flash — Faster, lower-cost Microsoft MAI Image 2.6 Flash for text-to-image, image editing, and multi-image composition
Features
- Text-to-image generation from prompts of up to 32,000 characters.
- Editing a single reference image, or combining up to 5 reference images into one image.
- Seven aspect ratios at
1Kor2K, plus customWIDTHxHEIGHTsizes. - Optional web search that looks up real-time information before generating, for current events and real places, products, or people.
Input modes
- Text-to-image — Omit
image_urls. The output size comes fromsizeandresolution. - Editing / composition — Pass 1 to 5 URLs in
image_urls. One image is edited; two or more images are combined into one. The output is about 1 megapixel and follows the reference images.
Required parameters
prompt(string): Description of the image or the requested edit, 1–32,000 characters. Must contain non-whitespace text. Put any exact on-image text in quotes.
Optional parameters
image_urls(array of strings): 1 to 5 publicly accessible HTTP(S) reference image URLs in JPEG, PNG, or WebP format. Selects editing / composition mode.size(string):1:1,4:3,3:4,3:2,2:3,16:9,9:16, or a customWIDTHxHEIGHT. Default is1:1. See Size.resolution(string):1Kor2K. Default is1K. Applies only to aspect-ratio sizes.enable_web_search(boolean): Look up real-time web information before generating. Default isfalse.
Size
Each aspect ratio maps to fixed pixel dimensions at the selectedresolution:
size | 1K | 2K |
|---|---|---|
1:1 | 1024×1024 | 1536×1536 |
4:3 | 1152×864 | 1760×1312 |
3:4 | 864×1152 | 1312×1760 |
3:2 | 1248×832 | 1856×1248 |
2:3 | 832×1248 | 1248×1856 |
16:9 | 1344×768 | 2048×1152 |
9:16 | 768×1344 | 1152×2048 |
- Custom
WIDTHxHEIGHTsizes need both sides divisible by 32, each side at least 768, and total pixels at most 2,359,296 (for example1536x1536or3072x768). A custom size is used exactly as given;resolutionapplies to aspect-ratio sizes.

}
}
Notes
- Each request returns one PNG image.
image_urlsmust be an array, even for one image.- In editing / composition mode, the output size follows the reference images. If you also send
sizeorresolution, use valid values. - Reference images larger than 1 megapixel are downscaled before generation.
