Features

FLUX.2 [turbo] — Text-to-Image

FLUX.2 [turbo] is the speed-optimized text-to-image model in the FLUX.2 family, built for ultra-fast generation with strong prompt adherence and dependable output quality. It’s ideal for real-time creation, high-volume pipelines, and rapid iteration where latency matters.

Where FLUX.2 [turbo] fits best

Real-time applications requiring low latency
High-volume batch generation workflows
Rapid iteration, prototyping, and creative exploration
Cost-sensitive production pipelines that still need consistent quality

Key benefits

Turbo-fast generation Optimized for minimal latency so you can generate more variations per minute.
Quality you can ship Designed to preserve the core FLUX.2 look and coherence while prioritizing speed.
Prompt-smart outputs Handles detailed prompts (objects, lighting, style cues) with reliable composition and fewer “random surprises.”
Format-ready files Supports common output formats including JPEG, PNG, and WebP for web, design, and production workflows.

Parameters

Parameter	Description
prompt*	Text description of the desired image (the more specific the prompt, the more consistent the result).
width	Output width (px).
height	Output height (px).
seed	Use -1 for random results, or set a fixed value for reproducible generations.

How to use

Write a detailed prompt describing subject, environment, style, and lighting.
Set output size by choosing width and height (square for general use, wide for banners, tall for posters).
Set a seed:
- Use -1 for random variations each run
- Use a fixed number to reproduce a result or explore controlled variations
Run the model and download the generated image.

Parameters

Task Submission Parameters

Request Parameters

Parameter	Type	Required	Default	Range	Description
prompt	string	Yes		-	The positive prompt for the generation.
size	string	No	1024*1024	256 ~ 1536 per dimension	The size of the generated media in pixels (width*height).
seed	integer	No	-1	-1 ~ 2147483647	The random seed to use for the generation. -1 means a random seed will be used.
enable_sync_mode	boolean	No	false	-	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_output	boolean	No	false	-	If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.

Response Parameters

data.model	string	Model ID used for the prediction
data.outputs	array	Array of URLs to the generated content (empty when status is not `completed`)
data.urls	object	Object containing related API endpoints
data.urls.get	string	URL to retrieve the prediction result
data.has_nsfw_contents	array	Array of boolean values indicating NSFW detection for each output
data.status	string	Status of the task: `created`, `processing`, `completed`, or `failed`
data.created_at	string	ISO timestamp of when the request was created (e.g., “2023-04-01T12:34:56.789Z”)
