How to Use FLUX 3 Klein

Start with a clear subject or a specific edit, then review the full image for unintended changes.

Choose Text for a new image or Edit for 1–10 reference images. Describe each reference by its order, such as image 1 and image 2.
Write the scene or edit instructions and choose an aspect ratio and resolution. Keep Enhance Prompt off for literal edits; it is enabled by default in Text mode.
Sign in, review the credit estimate and generate one PNG. Inspect text, product geometry, faces and unchanged areas before using the result.

FLUX 3 Klein Questions

Is this the full FLUX 3 model family?

No. This page runs the FLUX 3 Klein image model for text-to-image and image editing. Other FLUX 3 variants and video generation are not included.

How many credits does FLUX 3 Klein use?

One image costs 2 credits at 1K, 3 credits at 2K or 7 credits at 4K. The same quote applies to Text and Edit. Sign-in and sufficient credits are required.

Can I edit several reference images together?

Yes. Edit accepts 1–10 reference images. Identify each by order in the prompt and explain what it should control. Auto aspect ratio follows the first image.

When should I turn off Enhance Prompt?

Turn it off when an edit must follow literal wording, preserve a composition or reproduce specific text. It is off by default in Edit mode. This does not guarantee that every unrequested detail stays unchanged.

Can I download the model or run it locally here?

This is an online generator, not a model-weight download or local deployment service. It returns one generated PNG. Custom dimensions and batch generation are not exposed here.

How can I turn the result into a video?

Save the generated image and upload it to Kling 4.0 Frames or the image-to-video tool. Video generation is a separate task with its own credit quote.
