Flux AI's Models: All Versions Compared
Developed a suite of models—Schnell, Dev, Pro, and Pro Ultra—balancing speed, quality, and accessibility. Offers open-source options for developers and high-resolution outputs for professional use.
FLUX AI's Models is Black Forest Labs' AI image generation suite — covering text-to-image generation and in-context image editing with photorealistic precision. From FLUX.1 [pro]'s benchmark-leading prompt fidelity to FLUX.2 [pro]'s 4-megapixel output with 10-reference multi-subject support, every FLUX model available on AI Compare Hub can be tested side-by-side against other leading AI image models, for free.
What you can create with FLUX AI's models
-
Photorealistic images from text
FLUX.1 [pro] and FLUX.2 [pro] produce photorealistic images that match or exceed DALL·E 3 and Midjourney on benchmark evaluations. The 12-billion-parameter rectified flow transformer architecture delivers sharp detail, accurate lighting, and strong prompt adherence across all subject types.
-
In-context image editing
FLUX.1 Kontext (released May 2025) introduced in-context editing — describe the change you want to make and provide the source image, and the model edits precisely without disrupting surrounding areas. Adobe integrated FLUX.1 Kontext Pro into Photoshop's Generative Fill in September 2025.
-
Ultra-high-resolution multi-reference images
FLUX.2 [pro] generates images up to 4 megapixels — the highest resolution in the FLUX family — and accepts up to 10 reference images simultaneously for multi-subject and brand-consistent creative work.
-
Rapid-iteration image generation
FLUX.1 [schnell] is available under an Apache 2.0 open-source licence and optimised for sub-second generation speed. Use it for fast concept exploration before refining with FLUX.1 [pro] or FLUX.2 for the final output.
-
Typography and text-accurate image generation
FLUX.2 [pro] pairs a Mistral-3 vision-language model with a rectified flow transformer, delivering exceptional typography accuracy within generated images — readable text, precise colour accuracy, and multi-character consistency.
Why creators choose FLUX AI's models
-
32-billion-parameter architecture FLUX.2 [pro]
FLUX.2 [pro] scales to 32 billion parameters — nearly 3x the size of the original FLUX.1 series — combining a Mistral-3 vision-language model with a rectified flow transformer. The result is a step-change in image quality, typography precision, and multi-subject coherence.
-
In-context editing without scene disruption
FLUX.1 Kontext is one of the only image models that can edit a specific region of an image based on a text instruction without altering surrounding areas. This makes precise creative revision possible without starting over, and underpins Adobe Photoshop's Generative Fill feature.
-
Open-source accessibility
FLUX.1 [schnell] is released under Apache 2.0 — freely available for commercial use, local deployment, and model fine-tuning. FLUX.1 [dev] is available for non-commercial use. This open-source commitment makes FLUX AI one of the few frontier image model providers accessible to developers without API dependency.
-
Multi-reference character consistency
FLUX.2 [pro] accepts up to 10 reference images simultaneously, enabling consistent multi-subject and multi-character generations. This directly addresses one of the most persistent challenges in AI image workflows: keeping the same characters, objects, and styles consistent across an image series.
-
Broad integration ecosystem
FLUX models are integrated into Adobe Photoshop Generative Fill (FLUX.1 Kontext Pro), Amazon Bedrock, and a growing range of developer tools. The $140 million Meta partnership further signals the ecosystem's commercial and research significance.
How to compare FLUX AI's models on AI Compare Hub
- Choose your generation type. FLUX AI's models support Text-to-Image generation and Image-to-Image editing via FLUX.1 Kontext variants. Select the generation type that fits your use case from the AI Compare Hub interface.
- Select a FLUX model version. Choose FLUX.1 [pro] for benchmark-level text-to-image, FLUX.1 Kontext for in-context editing, FLUX.2 [pro] for maximum resolution and multi-reference support, or FLUX.1 [schnell] for rapid-iteration generation. Add one or more other models to compare against.
- Enter your prompt and generate. Write your prompt, set aspect ratio and resolution, then generate. AI Compare Hub runs all selected models simultaneously — results appear side-by-side for direct comparison.
Common questions
What AI models does FLUX AI offer on AI Compare Hub?
FLUX AI's model family on AI Compare Hub includes FLUX.1 [schnell] (Apache 2.0 open-source), FLUX.1 [dev] (non-commercial), FLUX.1 [pro] (API), and FLUX.1 Kontext variants for image editing. The FLUX.2 series — including FLUX.2 [pro] (32B parameters, 4MP output), FLUX.2 [max], FLUX.2 [dev], and FLUX.2 [klein] — represents the latest generation with sub-second generation capability on consumer hardware.
What is the difference between FLUX.1 and FLUX.2?
FLUX.1 (the original series) uses a 12-billion-parameter rectified flow transformer and sets the benchmark for text-to-image quality and prompt fidelity. FLUX.2 (launched November 2025) scales up to 32 billion parameters and combines a Mistral-3 vision-language model with the rectified flow architecture — delivering higher resolution up to 4MP, stronger typography, and multi-reference support for up to 10 input images simultaneously.
What is FLUX.1 Kontext?
FLUX.1 Kontext (released May 2025) is Black Forest Labs' in-context image editing model. It allows users to describe a specific change to make to an existing image — editing only the specified region without disrupting surrounding areas. FLUX.1 Kontext Pro was integrated directly into Adobe Photoshop's Generative Fill tool in September 2025.
Which FLUX model is best for AI image generation?
FLUX.2 [pro] is the highest-quality option for maximum resolution, multi-reference support, and typography accuracy. FLUX.1 [pro] is the proven choice for benchmark-level text-to-image with strong prompt fidelity. FLUX.1 Kontext is the best option when you need to edit existing images rather than generate from scratch. FLUX.1 [schnell] is the best choice for rapid iteration and local deployment.
Are FLUX models available for local deployment?
Yes — FLUX.1 [schnell] is released under an Apache 2.0 open-source licence and available for free local deployment and commercial use. FLUX.1 [dev] is available under a non-commercial research licence. FLUX.2 [klein] (January 2026) offers sub-second generation at 4B and 9B parameter sizes under Apache 2.0, optimised specifically for consumer hardware deployment.
