FLUX.2 Pro Text-to-Image API by Black Forest Labs
FLUX.2 Pro is a state-of-the-art text-to-image generation model that raises the bar for photorealistic quality, prompt fidelity, and production reliability. Built on a multimodal flow matching architecture, it delivers up to 4MP coherent scenes with realistic lighting, spatial logic, and fine detail that close the gap with professional photography.
FLUX.2 Pro — Text to Image
Developer: Black Forest Labs
Model ID: black-forest-labs/flux-2-pro/text-to-image
Release Date: November 25, 2025
Overview
FLUX.2 Pro is a state-of-the-art text-to-image generation model that raises the bar for photorealistic quality, prompt fidelity, and production reliability. Built on a multimodal flow matching architecture, it delivers up to 4MP coherent scenes with realistic lighting, spatial logic, and fine detail that close the gap with professional photography.
FLUX.2 Pro is designed for real-world production pipelines, combining maximum quality with practical generation speeds — typically under 10 seconds — making it suitable for high-throughput commercial workflows.
Key Capabilities
- Production-grade quality up to 4MP — High-fidelity, coherent scenes with realistic lighting, spatial logic, and fine detail.
- Brand-accurate results — Exact hex-color matching, reliable typography, and structured controls (JSON, pose guidance) for fewer manual fixes and stronger brand compliance.
- Strong prompt fidelity — Precise positioning, physics-aware lighting, and composition control with support for up to 32K tokens for long and detailed prompts.
- Balanced speed and quality — Optimized to deliver maximum quality while keeping generation times practical, enabling real-world production pipelines.
Use Cases
- Commercial advertising — High-quality product visuals, campaign assets, and promotional imagery at scale.
- Brand asset creation — Logos, signage, and branded content with hex-code color accuracy and typographic precision.
- Creative production — Concept art, editorial illustration, and photorealistic scene generation.
- Rapid prototyping — Fast iteration on visual ideas without manual editing overhead.
Input Parameters
| Parameter | Type | Default | Range | Description |
|---|---|---|---|---|
prompt | string | — | — | Text description of the image to generate. Required. |
width | integer | 1024 | 256–2048 | Width of the generated image in pixels. |
height | integer | 1024 | 256–2048 | Height of the generated image in pixels. |
output_format | string | jpeg | jpeg, png | Output image format. |
safety_tolerance | integer | 2 | 0–5 | Moderation strictness level. 0 = most strict, 5 = least strict. |
seed | integer | -1 | — | Random seed for reproducibility. Use -1 for a random seed. |
Output
Returns a URL to the generated image. The model supports asynchronous generation: the response first contains a polling URL, which resolves to the final image once generation is complete.
Output formats: JPEG, PNG Maximum resolution: 4 megapixels (e.g., 2048×2048)
Pricing
Pricing is based on the resolution of the generated image, measured in megapixels (MP). 1 MP = 1,048,576 pixels (e.g., 1024×1024). Resolution is capped at 4 MP for billing purposes.
SKUs
| SKU | Description | Unit Price |
|---|---|---|
sku_gen_first_mp | First megapixel of the generated image | $0.03 |
sku_gen_extra_mp | Each additional megapixel beyond the first (up to 4 MP) | $0.015 |
Formula
cost = sku_gen_first_mp + max(0, min(4, ceil(width × height / 1,048,576)) - 1) × sku_gen_extra_mp
Examples
| Resolution | Megapixels (billed) | Cost |
|---|---|---|
| 1024×1024 | 1 MP | $0.030 |
| 1024×1536 | 2 MP | $0.045 |
| 1536×1536 | 3 MP (ceil) | $0.060 |
| 2048×2048 | 4 MP | $0.075 |
Megapixels are always rounded up (
ceil). The first megapixel is billed at 0.015. Resolution beyond 4 MP is not additionally charged.
