Features

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

How to use

1. Write a detailed prompt describing subject, environment, style, and lighting.
2. Set output size by choosing width and height (square for general use, wide for banners, tall for posters).
3. Set a seed:

• Use -1 for random variations each run
• Use a fixed number to reproduce a result or explore controlled variations

4. Run the model and download the generated image.

Pricing

• $0.01 per generated image
