What Makes FLUX Different
FLUX represents the cutting edge of text-to-image generation, developed by Black Forest Labs — the same research team behind Stable Diffusion. Unlike earlier diffusion models that required negative prompts, classifier-free guidance tuning, and careful seed management, FLUX models understand natural language with remarkable precision. You describe what you want in plain English; the model delivers.
On Fauxto Labs, we provide access to the complete FLUX ecosystem — four generation models and two editing models. The lineup spans two generations: the original FLUX 1 (SRPO) and the newer FLUX 2 family, which includes FLUX 2, FLUX 2 Pro, and FLUX 2 Flex for generation, plus FLUX 2 Edit and FLUX Edit Pro for image editing. Understanding when to reach for each model can dramatically improve your output quality while saving credits.
Three qualities set FLUX apart from the competition: superior prompt understanding that faithfully renders complex scene descriptions, exceptional photorealism and detail that holds up at print resolution, and a versatile style range spanning fashion editorial to documentary photography to digital illustration.
FLUX 2 Pro
FLUX 2 Pro is the flagship generation model — professional-grade output with the highest fidelity in the FLUX lineup. At 8 credits per image, it delivers stunning detail, precise prompt adherence, and commercial-ready quality that you can confidently use for hero images, campaign key art, and high-resolution print work.
If your project demands the absolute best from FLUX and you want images that survive close inspection at large sizes, FLUX 2 Pro is the model to reach for. It excels at complex compositions, realistic skin textures, accurate text rendering, and nuanced lighting scenarios.
FLUX 2
FLUX 2 is the workhorse of the second-generation lineup. At 5 credits per image, it offers a significant quality jump over the original FLUX 1 while keeping costs manageable. FLUX 2 produces enhanced realism, better color accuracy, and notably crisper text rendering in images — a common pain point with earlier models.
For most day-to-day generation tasks — social media assets, blog illustrations, concept art, and product mockups — FLUX 2 is the sweet spot between quality and budget. It handles complex scenes with multiple subjects well and produces consistent, reliable results across a wide range of styles.
FLUX 2 Flex
FLUX 2 Flex sits between FLUX 2 and FLUX 2 Pro at 6 credits per image. What makes it unique is its built-in prompt expansion capability — it intelligently extends shorter prompts with creative details, making it ideal for users who prefer quick, conversational descriptions rather than meticulously crafted prompts.
If you often find yourself writing short prompts like “a sunset over a mountain lake” and wanting the model to fill in the cinematic details, FLUX 2 Flex is your best bet. It adds artistic interpretation without losing the core intent, producing images that feel more creative and dynamic than a literal interpretation.
FLUX 1 (SRPO)
FLUX 1, also known as FLUX SRPO, is the original FLUX model that established the family's reputation. At 5 credits per image, it delivers raw, authentic photorealism with a documentary-style aesthetic. While the FLUX 2 family has surpassed it in several areas, FLUX 1 still holds its own for lifestyle photography, natural portraits, and content where authenticity matters more than polish.
The images from FLUX 1 feel like they were captured by a skilled photographer on location rather than composited in a studio. If your brief calls for “real” rather than “perfect,” FLUX 1 remains a strong and cost-effective choice.
BeforeAfterFLUX Edit Pro
FLUX Edit Pro (10 credits) is the premium image editing model. Upload an existing image and describe the change you want in natural language — it handles complex edits like changing entire backgrounds, swapping outfits, adjusting lighting conditions, and making precise object modifications while maintaining perfect coherence with the rest of the image.
When you need high-stakes editing for commercial work, client deliverables, or any scenario where the result needs to look flawless, FLUX Edit Pro delivers the precision and quality to get it right.
FLUX 2 Edit
FLUX 2 Edit (7 credits) offers the same text-based editing approach as Edit Pro at a lower cost, making it ideal for routine adjustments like color corrections, style transfers, and moderate composition changes. It accepts a reference image and a text prompt describing the desired change.
For iterative workflows where you're making multiple edits and refinements, FLUX 2 Edit keeps the per-edit cost manageable while still delivering strong results across a wide range of modification types.

Advanced Prompting Techniques
Mastering FLUX starts with understanding how to craft effective prompts. The models respond best to structured, descriptive language — think of it as writing a shot list for a photographer rather than typing keywords into a search engine.
The Prompt Formula
A reliable structure is: Subject + Action/Pose + Environment + Style + Technical Details. For example: “A professional woman, sitting confidently, in a modern office, corporate headshot style, 85mm lens, soft lighting, high detail.” Each component adds specificity that steers the model toward your intent.
Quality Enhancers
Appending terms like highly detailed, 8K resolution, photorealistic, and sharp focus nudges the model toward higher-fidelity output. These work across all FLUX models but have the most visible impact on FLUX 2 Pro, which has the headroom to render that extra detail.
Style Modifiers
Words like cinematic, dramatic lighting, golden hour, studio photography, and editorial style give the model a clear creative direction. Combining a style modifier with technical terms — “shallow depth of field, rule of thirds composition, professional color grading” — produces results that feel intentional rather than random.
Generation vs. Editing
When using FLUX generation models (FLUX 2 Pro, FLUX 2, FLUX 2 Flex, FLUX 1), write your prompt as a complete scene description. When using FLUX editing models (FLUX Edit Pro, FLUX 2 Edit), write your prompt as an instruction describing the change you want: “Change the background to a tropical beach at sunset” or “Replace the red dress with a blue business suit.” The editing models understand modification language naturally.
Aspect Ratios
All FLUX models support multiple aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, and 21:9. Choosing the right aspect ratio upfront avoids awkward crops later and gives the model more room to compose the scene naturally for your intended output format.
Choosing the Right FLUX Model
With six models in the lineup, picking the right one comes down to what you're trying to do. For generating new images from text, start with FLUX 2 (5 credits) for everyday work, step up to FLUX 2 Pro (8 credits) for premium output, or try FLUX 2 Flex (6 credits) if you prefer shorter prompts with creative interpretation. FLUX 1 (5 credits) is still a strong option for natural, documentary-style imagery.
For editing existing images, FLUX Edit Pro (10 credits) handles complex modifications like background swaps, outfit changes, and lighting adjustments, while FLUX 2 Edit (7 credits) covers routine adjustments like color corrections and style transfers at a lower cost.
Frequently Asked Questions
Which FLUX model should I use for portraits?
For the highest quality portraits, use FLUX 2 Pro (8 credits). For everyday portrait work, FLUX 2 (5 credits) delivers excellent results at a lower cost. For natural, documentary-style portraits, FLUX 1 (5 credits) produces an authentic look. If you want to modify an existing portrait, use FLUX Edit Pro (10 credits) or FLUX 2 Edit (7 credits) to adjust lighting, backgrounds, or styling.
What's the difference between FLUX 2 and FLUX 2 Pro?
FLUX 2 (5 credits) is the standard second-generation model with enhanced realism and better text rendering.
