## Flux 2 Flex - Online AI Image Generator

The current Flux 2 Flex form accepts a text prompt or up to eight reference images and exposes Flex or Pro variants, eight aspect ratios, 1K or 2K output, and output count.

## Flux 2 Flex reference and prompt examples

The gallery illustrates typography, portrait, product, concept-art, logo, and illustration directions; it is not a benchmark or output guarantee.

## Why Flux 2 Flex

The live form exposes variant, reference, ratio, resolution, and output-count choices. Those controls, not generic model claims, define what this page can submit.

### Prompt-led generation

Start from a required prompt of up to 5,000 characters. Evaluate the returned image against every requested subject, action, layout, and text detail rather than assuming adherence.

### Up to eight reference images

Image mode accepts one to eight JPEG, PNG, or WebP files, each up to 10 MB, so a run can be conditioned on supplied visual material.

### Flex and Pro variants

The variant control offers Flex and Pro. Treat the labels as selectable form options and compare returned results; the page does not promise that one wins every task.

### 1K and 2K output settings

The resolution control offers 1K and 2K. Inspect the delivered dimensions and image detail after each run before using an asset downstream.

### Eight aspect ratios

Choose 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, or Auto. Ratio controls framing, not prompt accuracy or identity preservation.

### Visible run settings

The browser form shows model access, inputs, settings, and the credit estimate before submission. Review those values again whenever the catalogue changes.

## Who uses Flux 2 Flex reference images, and for what?

Designers, marketers, ecommerce teams, and concept artists can use these candidate workflows to evaluate prompt, reference, variant, ratio, and resolution controls; every returned image still needs review.

### Marketing and social concepts

Test poster, ad, and social-layout ideas, then verify text, logos, product details, and disclosure requirements before publication.

### Brand-direction exploration

Explore shapes, colors, and lettering directions as drafts. Generated marks and words require human redraw, rights review, and exact typography checks.

### Concept art and illustration

Compare visual directions for characters, environments, and key art while checking composition and subject details against the prompt.

### Product mockups

Use supplied product references to test studio or lifestyle concepts, then reject results that alter packaging, labels, proportions, or regulated claims.

### Reference-led variations

Provide visual references when a style board, character sheet, or product photo should condition the run; references guide rather than lock the result.

### Variant and resolution comparisons

Hold the prompt and references constant while comparing Flex versus Pro or 1K versus 2K, then record which returned result fits the task.

## Flux 2 Flex reference-image FAQ

Answers about the current form's access, inputs, variants, ratios, resolutions, output count, credit estimate, and review boundaries.

### What is Flux 2 Flex?

Flux 2 Flex is a selectable image model in this app. Its form accepts text or image input and exposes Flex or Pro, ratio, 1K or 2K, and output-count controls.

### What access is required for this model?

The current catalogue marks this as a paid-access model. Confirm access and the displayed credit estimate before submitting; do not rely on an old free-access description.

### Which variants can I select?

The variant control offers Flex and Pro inside the same form. Compare them with the same prompt and references because the labels alone do not establish the better result for a task.

### Which resolutions and ratios are available?

The form offers 1K or 2K and eight ratio choices: 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, and Auto. Verify delivered dimensions after the run.

### What run time and credit estimate are configured?

The model metadata estimates about 60 seconds and 2 credits. Queue conditions and returned task state can vary, so treat both as current form estimates rather than guarantees.

### Can paid-plan output be used commercially?

Paid plans include this app's commercial license. You remain responsible for prompt and reference rights, applicable model terms, and the final use.

### How many reference images can image mode accept?

Image mode accepts one to eight JPEG, PNG, or WebP files up to 10 MB each. References condition the run but do not guarantee identity, text, or product-detail preservation.

### What output-count control is available?

The live form includes an output-count field. Read the available values and updated credit estimate before submitting because count can affect the run cost.

### Does this page expose guidance or sampling-step controls?

No. The current form does not expose guidance scale or sampling steps. Use only the variant, ratio, resolution, reference, and output-count controls that are actually displayed.

### What limits should I check before using Flux 2 Flex?

Generated output from Flux 2 Flex can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use. Where the form accepts a reference image, supported files are JPEG, PNG, WebP up to 10 MB each.

### What happens to the files I upload to Flux 2 Flex?

An upload is stored against your own account, not pooled with other people's. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure removes the stored objects it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what Flux 2 Flex makes commercially?

Every paid plan includes a commercial licence for what Flux 2 Flex makes; the free tier is for personal use.
