Features

FLUX.2 [dev] — Edit

FLUX.2 [dev] Edit is the lean editing companion to FLUX.2 [dev] Text-to-Image: a lightweight, open-source model that updates existing images quickly while keeping their core look intact. It is built for day-to-day production tasks where you need reliable edits at scale without burning GPU budget.


Built for

  • Quick visual tweaks to existing assets
  • Consistent updates to product, UI, or brand imagery
  • High-volume editing in cost-sensitive pipelines
  • Workflows already using FLUX.2 [dev] for generation
  • LoRA-based domain or brand customisation on a small footprint

Lean editing engine for everyday pipelines

Instead of regenerating images from scratch, FLUX.2 [dev] Edit focuses on local changes. You feed it an image plus an edit prompt (and, when supported, a mask or strength setting); it modifies only the requested areas, keeping layout, characters, and overall style stable so assets remain recognisable across versions.


Key benefits

• Prompt-guided adjustments

Change lighting, colour, clothing, props, or background details with short text instructions, replacing manual retouching and pixel-level editing.

• Consistent look and feel

Refresh campaigns, seasonal variants, or A/B test creatives while preserving character identity, composition, and brand language across all outputs.

• Open and integration-friendly

Built on the same open FLUX.2 stack, making it straightforward to plug into internal tools, debug behaviour, or extend with custom logic.

• Small, efficient footprint

The compact dev architecture keeps inference costs low, which is ideal for batch processing, automation, and always-on backend services.

• Flexible I/O

Accepts standard image formats and returns JPEG or PNG, so edited results fit directly into web, design, and post-production workflows.

• Repeatable results

Seed control plus fixed prompts make it easy to recreate previous edits or generate controlled variations for QA, experimentation, and asset refreshes.


Pricing

Simple per-image billing:

  • $0.024 per edited image

Parameters

Task Submission Parameters

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The positive prompt for the generation.
imagesarrayYes[]1 ~ 3 itemsList of URLs of input images for editing. The maximum number of images is 3.
sizestringNo-256 ~ 1536 per dimensionThe size of the generated media in pixels (width*height).
seedintegerNo-1-1 ~ 2147483647The random seed to use for the generation. -1 means a random seed will be used.
enable_sync_modebooleanNofalse-If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API.
enable_base64_outputbooleanNofalse-If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
