Generate images with FLUX.2 [dev] for free, without an account: the open-weights text-to-image model released by Black Forest Labs in late 2025, known for sharp detail, faithful prompt following, readable text inside images, and editing guided by reference pictures. Write a sentence, get a high-resolution image in the embedded demo below.

How to use FLUX.2

  1. Describe the image as a full sentence, with the text you want rendered between quotes if any.
  2. Optionally add one or more reference images to keep a character, a product or a style consistent.
  3. Click Generate and wait for the shared queue; a 1-megapixel image takes tens of seconds.
  4. Download the result, or refine the sentence rather than adding keyword lists: FLUX follows language, not tags.

Limits and questions

What is the difference between FLUX and Stable Diffusion?

Both are open text-to-image models. FLUX (FLUX.1 in 2024, FLUX.2 in 2025, FLUX 3 in 2026) uses a larger flow-matching transformer with much better prompt adherence and text rendering. The large [dev] checkpoints need far more VRAM than SD 1.5 or SDXL, the Klein models much less, and all of them have fewer community fine-tunes.

Can I run FLUX on my own computer, and is FLUX 3 out?

Yes to both. FLUX.2 [dev] is downloadable from Hugging Face under a non-commercial licence, but it has 32 billion parameters: expect 24 GB of VRAM or more, or quantised versions in ComfyUI. FLUX 3 Image Klein, published with open weights on 15 October 2026, has 5.6 billion parameters, generates native 4K and runs on an 8 GB card with its int8 build. It ships as two checkpoints, a step-distilled one for generation and a base one for fine-tuning, under the FLUX Kommunity License: free commercial use under 5 million dollars in annual revenue, a commercial licence above that. This demo runs FLUX.2 [dev].

Why is the demo slow or unavailable?

This demo is hosted by a third party (Hugging Face Space) and embedded here; it can be slow, queued or temporarily unavailable when the host is busy. Nothing to install, no account needed.
