FLUX Image Generator - Text to Image

Turn text prompts into high quality images. Generate one image or hundreds in a single run, choose from fast FLUX models or premium Gemini and GPT image models, and get every image hosted on a stable URL you can drop straight into a sheet, CMS, or app.

Models

• FLUX schnell - fastest and lowest cost, great for bulk runs
• FLUX dev - higher quality FLUX
• Gemini 2.5 Flash Image / Nano Banana and Gemini 3 Flash Image / Nano Banana 2
• Gemini 3 Pro Image - premium quality
• GPT-5 Image and GPT-5 Image mini

FLUX models are fast and cheap; the Gemini and GPT image models produce premium results at a higher cost per image.

What you get

• A generated image for every prompt
• Square, portrait, landscape, wide, and tall aspect ratios
• Up to 4 variations per prompt
• A stable hosted image URL for each result, plus the prompt, model, provider, and dimensions in one clean row
• Optional fixed seed for reproducible results on FLUX models

Use cases

• Blog, ad, and social media visuals at scale
• Product and concept mockups from a list of ideas
• Thumbnails and hero images for content pipelines
• Bulk creative testing across many prompts at once

How to use

1. Add one or more Prompts, one image idea per line
2. Pick a Model: FLUX schnell for fast and cheap, FLUX dev for higher quality
3. Choose an Aspect ratio and Images per prompt
4. Optionally set an Output format and a fixed Seed
5. Run the actor. Each image appears as a row in the Dataset tab, and the files live in the Key-value store

Input example

{
  "prompts": [
    "A golden retriever puppy in a field of sunflowers, soft morning light, photorealistic",
    "Minimal product shot of a matte black water bottle on a marble surface"
  ],
  "model": "flux-schnell",
  "aspectRatio": "1:1",

  "height": 1024,

}

Free tier

You can try this actor for free, with limits:

• Up to 3 images per run, generated on the fast FLUX schnell model
• 3 runs per day, with a 30-minute cooldown between runs

Upgrade to a paid plan to use every model (including the premium Gemini and GPT image models), generate up to 4 images per prompt across 25 prompts, and run without daily limits or cooldowns.

Notes

• The imageUrl is a stable, public link to the file in this run's key-value store. Download it or reference it directly.
• Each prompt is generated independently, so one bad prompt never stops the rest of the run. Failed prompts come back with status set to error and a short message.
• Use a fixed seed when you want the same prompt to produce the same image across runs.
