What are the FLUX Tools?
Last updated: June 12, 2026
FLUX Tools are purpose-built editing endpoints for specific tasks. They complement the general FLUX.2 models, which handle text-to-image and prompt-based editing. Each tool takes an input image and returns a result through the same async submit-and-poll pattern as the rest of the API.
Tool | What it does | You provide | Pricing |
FLUX Outpainting | Extends an image beyond its original borders, filling the new area with coherent content. | An input image and a larger target canvas | from $0.10/MP |
FLUX Eraser | Removes a masked object and rebuilds the scene behind it. | An input image and a mask of what to remove | from $0.03/image |
FLUX Virtual Try-On | Dresses a person in a garment, keeping their face and pose. | A person image and a garment reference | from $0.037/image |

How billing works
Like all generations, you are only charged for successful results. Failed or moderated requests do not consume credits.
