Flux 2 Pro
32 billion parameters. Hex colour precision. Up to 4MP.
From Black Forest Labs, Flux 2 Pro is a 32-billion parameter model combining a Mistral-3 24B vision-language model with a rectified flow transformer. Nearly 3x the parameter count of its predecessor. It accepts hex colour codes directly in prompts and reproduces them with exact accuracy, making it the go-to model for brand work and material studies where colour fidelity matters.
Example outputs
“A contemporary office lobby with polished concrete floors, #C8A97E brass reception desk, diffused overhead lighting, architectural photography”
“A sports car in #1B3A5C midnight blue, three-quarter front view on a reflective dark surface, studio automotive photography”
“Character concept art: a cyberpunk street vendor, detailed clothing and gear, neon-lit alley background, concept art style”
“A ceramic homeware collection arranged on a linen backdrop, soft natural light from the left, editorial product photography”
“An outdoor restaurant terrace at golden hour, string lights, timber and greenery, warm Mediterranean atmosphere”
“A fitness app onboarding screen, bold typography, clean layout with progress indicators, dark mode UI design”

Flux 2 Pro from Black Forest Labs is a 32-billion parameter image generation model. It uses a latent flow matching architecture that combines a Mistral-3 24B vision-language encoder with a rectified flow transformer. The result is the strongest prompt-following accuracy in its class, with photorealistic output at resolutions up to 4 megapixels.
The standout feature for design professionals is hex colour matching. Include a hex code in your prompt and Flux 2 Pro reproduces it with zero drift. No more guessing whether the model will interpret 'brand orange' correctly. Specify #E07830 and get #E07830. This is transformative for brand guidelines, material palettes, and any workflow where colour accuracy is non-negotiable.
Flux 2 Pro also processes up to 10 reference images simultaneously, preserving character features, product details, and style elements across multi-image prompts. Generation takes 2-4 seconds with configurable speed and quality settings.
Built for brand work
Hex colour codes, multi-reference consistency, and photorealistic rendering make Flux 2 Pro the natural choice for brand identity work, packaging design, and any project with strict colour specifications.
Architecture and product visualisation
The 32B parameter scale handles complex compositional prompts with multiple elements, materials, and lighting conditions. Architectural renders, interior scenes, and product photography benefit from the model's ability to maintain coherence across busy compositions.
Speed and quality balance
Generates in 2-4 seconds with configurable settings. Run fast for iteration, switch to quality mode for the final render. The speed-to-quality ratio makes it practical for real-time design sessions.
