How to compare FLUX AI's models on AI Compare Hub

  1. 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.
  2. 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.
  3. 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.
