What are the resolution limits?
FLUX.2 generates images up to 4MP (e.g., 2048x2048).
Parameter | Value |
Minimum resolution | 256 x 256 pixels |
Maximum resolution | 4 megapixels (e.g., 2048x2048) |
Dimension step | Multiples of 16 pixels |
Default (no input) | 1024 x 1024 |
Any aspect ratio | Supported |
We recommend staying at or below 2MP for optimal quality and speed. Input images over 4MP are automatically resized.
FLUX.1 Kontext outputs at a fixed 1MP resolution with flexible aspect ratios. Dimensions are adjusted to multiples of 32 pixels.
