# FLUX 3 Image now available on AI Gateway

By Steven Van · 2026-10-05

Developers can generate and edit images with up to ten references using one API key, without a Black Forest Labs account.

Text prompts and existing images can use the same Black Forest Labs model through [Vercel](<https://creatorstoolbox.com/tools/vercel>) AI Gateway, with one API key and no Black Forest Labs account required.

## Reference images and resolution

FLUX 3 Image supports up to ten reference images for editing, combining subjects, or changing composition. It offers five resolution tiers from 768 × 768 to 4K, with square, portrait, and landscape aspect ratios.

## Generate and edit with the AI SDK

To get started, set AI\_GATEWAY\_API\_KEY and use bfl/flux-3-image as the model ID in AI SDK 7 or later. Call generateImage with a text prompt to create an image. To edit one, pass it in prompt.images alongside an instruction describing the change.

The release note demonstrates generating a square, 1K image of a blue ceramic vase, then changing the vase to terracotta while keeping the flowers and setting.

## Terminal access

FLUX 3 Image also works through AI CLI with the same API key and model ID. The terminal command accepts a prompt and an output directory to generate and save an image. Vercel’s [image generation guide](<https://vercel.com/docs/ai-gateway/modalities/image-generation/ai-sdk>) covers the AI SDK workflow.
