Flux AI Image Generator

Flux is a family of AI image models made by Black Forest Labs. You write what you want to see, and Flux makes the picture. FLUX.2 is the newer family, from the small Klein models up to Pro and Max. Enhance AI is not linked to Black Forest Labs. We let you use Flux online, next to every major AI model, in one account.

It is free to try. You need an account, and making one is free with no card. New accounts get free tokens, and they work on every Flux model, Flux 2 Pro and Flux 2 Max too. A picture costs 1 to 20 tokens, depending on the model. The free tokens come once and do not refill. When they run out, plans start at $19, paid one time. No account yet? Our free image generator makes 3 pictures a day with no account. It uses a different AI model, not Flux.

Start with Flux 2 Klein 9B. It costs 3 tokens a picture and can use up to 3 of your own images. For quick, cheap tries, use Flux Red at 1 token. It can make up to 4 pictures at once. For words in the picture, like a poster title, use Flux 2 Pro (9 tokens) or Flux 2 Max (20 tokens).

Say what the picture is of first. Then add the details, the place, the light and the style. For example: a ceramic coffee mug, steam rising, on a wooden table, morning window light, close up product photo. Say what you want, not what you do not want: write "an empty street", not "no people". Put exact words in quotes, and use Pro or Max for them. Test a new prompt on Flux Red for 1 token, then use your best one on Klein 9B.

Yes, on the models that take your images. Upload up to 3 photos on Flux 2 Klein 4B, Flux 2 Klein 9B, Flux 2 Pro and Flux 2 Max, or 1 photo on EA Flux 2, and say what to change. Flux Red and Flux 2 Turbo work from words only. For more ways to change a photo, see image to image.

Use Flux 2 Pro or Flux 2 Max for that. Put the exact words in quotes and keep them short. Always check the spelling before you use the picture. The other Flux models can try, but check their letters closely.

FLUX.2 is the second version of Flux from Black Forest Labs. Here, the FLUX.2 models are Klein 4B, Klein 9B, Turbo, Pro, Max and EA Flux 2. Flux Red is built on the first version, FLUX.1, and is the lowest cost Flux model here. Flux Red and EA Flux 2 are names from Enhance AI. Our FLUX.2 page tells you more.

Pick a shape: square, wide (3:2, 4:3 or 5:4), tall (2:3, 3:4 or 4:5) or 9:16 for reels and stories. You can also add a style, like Watercolor or Anime AI. Pictures come out at up to about 1 megapixel, like 1024 by 1024 for a square. That looks sharp on a phone but is small for a big print, so make it bigger first with the AI image upscaler. It works with no account, 3 pictures a day. There is no watermark on Flux pictures.

Yes. You own the pictures you make and can use them for personal or commercial work, like ads, client work and products you sell. You are responsible for what you make and for any photo you upload. Section 6 of the terms has the exact words.

Like every AI image model, it can slip on hands, small details and crowds, and letters can come out wrong. The same person can also look different in each picture, because every run starts fresh. Adding your own images helps keep a face the same on Klein, Pro and Max. These guides help: how to fix AI hands and fixing AI image problems.

No install. Flux runs on our servers, so it works in the browser on any phone or computer. You cannot upload your own LoRA here, because each Flux model runs as it is. If you run Flux on your own computer, our guide shows how to merge a LoRA into a checkpoint.

Yes, with image to video. Video is not paid with tokens. It is paid from your wallet, which starts at zero on a new account, so free tokens do not cover video. You see the price before you make one.
