In the fast-paced world of artificial intelligence, a German start-up has caused quite a stir: Black Forest Labs from Freiburg im Breisgau. Founded in 2024 by Robin Rombach, Andreas Blattmann and Patrick Esser – all former employees of Stability AI and co-developers of the ground-breaking Stable Diffusion – the company has quickly made a name for itself in the AI image generation industry.
The three founders previously conducted research in the field of AI image generation at the Ludwig Maximilian University of Munich under the direction of Björn Ommer. Their expertise flowed into the development of Stable Diffusion before they decided to go their own way with Black Forest Labs. With an impressive funding round of 31 million dollars behind them, the company launched in 2024 and has been working on the further development of its Flux models ever since.
Flux 1.1pro is the premium model from the Flux family and is characterized by the following main features:
-
- Outstanding picture quality: Remarkable details, realistic textures and natural lighting effects
- Precise prompt compliance: Understanding complex instructions with high accuracy
- Lightning-fast generation: Around 6 times faster than previous models (less than 10 seconds per image)
- Versatile output formats: Support for different image sizes and formats
- High output diversity: different creative interpretations from the same prompt
In the market for AI image generators, Flux 1.1pro is positioning itself as a premium alternative to established models, combining more realistic images with a competitive pricing model.
Flux 1.1pro vs. DALL-E: A detailed comparison
Picture quality and realism
Flux 1.1pro delivers exceptional realism and detail, especially in portraits and human figures. While DALL-E 3 delivers impressive artistic interpretations, Flux 1.1pro demonstrates superior capabilities in realistic textures, lighting effects and anatomical correctness.
Prompt fidelity and speed
Both models demonstrate high prompt fidelity with different strengths: DALL-E 3 often interprets complex conceptual instructions more creatively, while Flux 1.1pro impresses with its more precise implementation of specific visual details. With generation times of less than 10 seconds, Flux is significantly faster than DALL-E 3.
Sample images in comparison
Portrait photo: With identical prompts, Flux 1.1pro produces more natural skin tones, more realistic hair textures, more authentic facial expressions and more detailed fabric textures.
Futuristic city: Flux 1.1pro convinces with superior light refractions, more coherent architectural details, stronger depth effect and more realistic color transitions.
Image size and use cases for Flux 1.1pro
Flux 1.1pro allows the dimensions of the image to be freely selected (max. 1440 x 1440 pixels). This enables the Evoya Agent to independently select the correct image size for a given application. Example prompt:“Create a header image for our LinkedIn page.”
Possible use cases
Flux 1.1pro is particularly suitable for:
-
- Professional applications: Product and architectural visualization, fashion design, concept art for film and games
- Creative projects: Book covers, social media content, art projects, personalized merchandise
- Business solutions: Customized image generation, integration into design workflows, automated content creation, prototyping
Flux 1.1pro from Black Forest Labs represents a significant advance in AI image generation and offers a convincing alternative to established models such as DALL-E 3:
-
- Outstanding realism in portraits and human figures
- Impressive speed for fast iterations
- Precise implementation of specific visual details
- Flexible configurability for different use cases
While DALL-E 3 continues to shine in conceptual and artistic interpretations, Flux 1.1pro impresses with its photorealistic quality and technical precision. The choice between the two models ultimately depends on the specific requirements of the project in question.
The future looks bright for Black Forest Labs and the Flux family of models. With their expertise in diffusion technology and focus on quality and speed, further innovations are likely to follow that will continue to push the boundaries of AI image generation.

Tip: To compare both image models, simply give the Evoya agent of your choice two image generation tools – one with DALL-E, one with Flux 1.1pro.
And this is how it works:
- Tools > Create two tools
- Select DALL-E for one model and Flux 1.1pro for the other
- Provide both tools to the agent of your choice
Done. We hope you enjoy trying it out!
