FLUX 3 Image Generator
FLUX 3 is Black Forest Labs' image generation model released on October 1, 2026. It generates images up to native 4K resolution, renders readable text inside images, and supports layout boxes that control where each element appears. This page runs FLUX 3 text-to-image in the browser: type a prompt, pick a size, and download the result — no install.
Powered by the FLUX 3 API (blackforestlabs/flux-3/text-to-image on fal.ai). Generation typically takes 5-20 seconds.
What is new in FLUX 3?
FLUX 3 shipped as a multimodal foundation with an image model on top. Compared with FLUX 2 (November 2025), the headline changes are:
| Capability | FLUX 2 (Nov 2025) | FLUX 3 (Oct 1, 2026) |
|---|---|---|
| Max resolution | 2MP typical | Native 2K and 4K output |
| Text in images | Improved, still error-prone at length | Precise text rendering (posters, UI mockups) |
| Layout control | Prompt-only | Layout boxes — place elements by region |
| Editing | Regional edits (dev) | Local edits + combine up to 10 references |
| Video | — | Image-to-video endpoint (single still → clip) |
How much does FLUX 3 cost?
Black Forest Labs sells FLUX 3 through its own API and partners like fal.ai, billed per generated image (higher resolution costs more). On this site you can try the model with free credits first, then buy credit packs — one credit covers a 1024px image, larger sizes cost proportionally more.
FLUX 3 or Nano Banana 2 — which one should you use?

Is there a free tier?
Yes — this tool offers free credits while capacity lasts. When the free queue is full, leave your email in the generator above and you get credits as soon as a slot opens. If you want to run FLUX 3 locally instead, watch Black Forest Labs' releases: earlier FLUX generations shipped open-weight variants, and we will update this page when a FLUX 3 open-weights version is confirmed.
