What FLUX Pro brings to the table
State-of-the-art prompt adherence
FLUX Pro consistently ranks at or near the top of independent benchmarks for prompt accuracy. Specific subjects, materials, lighting, and composition land reliably without re-prompting.
Cinematic photorealism
Output rivals Midjourney 6 for photorealism with stronger prompt fidelity. The model handles human hands, complex lighting, reflections, and material textures cleanly.
Fast production-grade generation
FLUX Pro generates a high-quality image in roughly 4.5 seconds - about 6x faster than its predecessor while keeping the same fidelity. That speed is why it became the default for production creative pipelines.
Up to 1440x1440 resolution
FLUX Pro supports image generation up to 1440 pixels on the long edge with multiple aspect ratios. Plenty for paid social, blog headers, and most commercial creative work.
Optional prompt upsampling
FLUX Pro includes optional prompt upsampling that enhances short prompts with additional descriptive detail. Useful for users who want strong output without prompt engineering.
Diverse style range
From photorealistic product shots to illustrative and artistic output, FLUX Pro handles a wide creative range in a single model. Style direction comes through as described.
Built for commercial use
FLUX Pro is designed for commercial workflows. It's integrated by Adobe Firefly, Mistral's Le Chat, and platforms across the creative software industry - the model has production scale baked in.
Pairs with the FLUX ecosystem
Use FLUX Pro for hero shots, Flux 2 Klein for fast iteration and editing, and FLUX 2 for the highest-fidelity hero work. All available on Fliki.
Top-ranked on Artificial Analysis
FLUX 1.1 Pro debuted under the codename 'blueberry' at the top of the Artificial Analysis text-to-image leaderboard, beating prior FLUX, Midjourney, and Ideogram releases on Elo score. That third-party benchmark is a cleaner signal than vendor demos when you're choosing a hero-shot model for production work.
How it works
How to generate an image with FLUX Pro
FLUX Pro runs inside Fliki's standard image generator. Here's the six-step flow.

Write your prompt
FLUX Pro rewards detailed prompts. Mention subject, action, environment, lighting, camera details, and style. For text inside images, put the words in quotes - FLUX Pro renders them clearly.

Select FLUX Pro as your model
Open Fliki's model selector and choose FLUX Pro. Your prompt is routed to Black Forest Labs' flagship production model.

Pick your aspect ratio
Choose 1:1, 16:9 or 9:16 depending on the destination. FLUX Pro supports all standard ratios with native composition.

Add reference images (optional)
Skip this step - FLUX Pro (FLUX 1.1 Pro) is a pure text-to-image model and does not accept reference inputs. For reference-driven workflows, use FLUX 2 or FLUX 2 Klein instead.

Set the resolution
FLUX Pro supports up to 1440x1440. Use lower resolutions for fast iteration; bump up when you're ready for final delivery.

Generate
Hit Generate. FLUX Pro returns in roughly 4.5 seconds. Optional prompt upsampling expands short prompts automatically - leave it on for creative exploration, off for strict control. Paid plans only.
