About FLUX.2 [dev]
FLUX.2 [dev] is a 32-billion parameter image generation model that excels in generating highly detailed, photorealistic images and performing precise image editing, including multi-reference editing with strong consistency across subjects, products, and styles. It is best at rendering complex typography, infographics, and UI mockups with legible fine text, and supports flexible input/output ratios up to 4 megapixels.
Some other noteworthy features of FLUX.2 [dev] include native support for LoRA fine-tuning workflows, making it suitable for rapid prototyping and custom training, and efficient resource usage for high-volume generation tasks.

https://hub.oxen.ai/api/ai/images/edit| Field | Type | Required | Default | Description |
|---|---|---|---|---|
prompt | string | Yes | — | Prompt for generated image. Use @Image1, @Image2, etc. to reference the input images. |
input_image | array<string>nullable | No | — | Input images to transform or use as reference. Reference them in the prompt as @Image1, @Image2, etc. |
aspect_ratio | string | No | "16:9" | 1:116:99:164:33:43:22:3match_input_image |
resolution | string | No | "1 MP" | 1 MP2 MP0.5 MP |
num_inference_steps | integer | No | 30 | Number of denoising steps. Recommended range is 28-50, and lower number of steps produce lower quality outputs, faster. Range: 1 – 50 |
guidance | number | No | 2 | Guidance for generated image. Lower values can give more realistic images. Good values to try are 2, 2.5, 3 and 3.5 Range: 0 – 10 |
seed | integernullable | No | — | Random seed. Set for reproducible generation |
output_format | string | No | "webp" | Format of the output imageswebpjpgpng |
output_quality | integer | No | 80 | Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs Range: 0 – 100 |
disable_safety_checker | boolean | No | false | Disable safety checker for generated images. |
