FLUX.2 Klein AI Image Generator — Text-to-Image & Image-to-Image ⚡

AI image generator and editor powered by FLUX.2 Klein — create stunning images from a text prompt, or transform an existing photo, in just a few seconds. No GPU, no subscription, no monthly fees: you pay a tiny fixed price per image. A fast, affordable alternative to Midjourney, DALL·E 3, and Adobe Firefly.

Two modes in one Actor:

• 🖋️ Text to Image — describe anything and get a high-quality image.
• 🖼️ Image to Image — edit, restyle, or transform a photo you already have (just add an image URL).

Perfect for social media content, product shots, blog and ad creatives, thumbnails, app assets, faceless content pipelines, and n8n / Make / Zapier workflows and AI agents.

Examples

Every image below was generated by this Actor with the default 4 steps — each took only a couple of seconds.

Text to Image

Image to Image

Start from one photo and restyle it with a prompt — the input below is the demo image from the imageUrl field:

Gallery — one model, every style

A few of the styles and domains FLUX.2 Klein handles out of the box — photography, illustration, 3D, concept art, design, and more. Every image below was generated by this Actor at the default 4 steps, square_hd (1024×1024), in about a second each:

Why this Actor?

• ⚡ Fast — FLUX.2 Klein is distilled for speed and runs in as few as 4 steps, generating an image in a few seconds (most hosted endpoints take much longer).
• 💸 Cheap — from $0.003 per image (as low as $3 per 1,000) for both text-to-image and image-to-image. Pay only for successful images; failed runs are never charged.
• 🎨 Quality — FLUX.2 Klein delivers sharp detail, strong prompt following, and excellent text rendering.
• 🔌 Automation-ready — call it from the Apify API, n8n, Make, Zapier, LangChain, or any AI agent via MCP.
• 📐 Flexible formats — square, portrait, and landscape sizes for text-to-image; 15 aspect ratios for image-to-image.
• 🖼️ Batch — generate up to 4 images per run.

How it compares

Great when you want image generation on demand without a subscription — ideal for occasional use, automated pipelines, and pay-as-you-go scaling.

How it works

1. Pick a Mode — Text to Image or Image to Image — and write a prompt.
2. For Image to Image, add a public image URL to edit (Mode switches automatically when an image is provided).
3. The Actor generates your image(s) and stores them in the run's dataset and key-value store.
4. Download the file(s) from the output, or pipe the URL into the next step of your workflow.

Input example — Text to Image

{
"mode":"text-to-image",
"prompt":"A beautiful sunset over a calm ocean, cinematic, highly detailed",
"imageSize":"landscape_16_9",
"numImages":1,
"numInferenceSteps":4,
"outputFormat":"jpeg"
}

Input example — Image to Image

{
"mode":"image-to-image",
"prompt":"make it a watercolor painting at sunset",
"imageUrl":"https://cdn.doggi-dev.net/media-gen-gateway/req-b6f24df387a7461788b4bfafffe9c7e7_0.jpeg",
"aspectRatio":"auto",
"numImages":1,
"outputFormat":"jpeg"
}

Output sizes

FLUX.2 Klein renders at roughly 1 megapixel. For Text to Image, pick imageSize:

For Image to Image, the output stays ~1 MP and follows aspectRatio (auto preserves the input image's ratio).

Output example

{
"imageUrl":"https://api.apify.com/v2/key-value-stores/.../records/image_1.jpg?signature=...",
"prompt":"A beautiful sunset over a calm ocean, cinematic, highly detailed",
"mode":"text-to-image",
"width":1024,
"height":576,
"seed":42,
"requestId":"req-...",
"model":"flux-2-klein-t2i"
}

Pricing

You are charged per generated image — for both text-to-image and image-to-image — at a price that drops with your Apify plan. The price is the same whether you generate 1 or 4 images per run.

Generate up to 4 images per run. Failed generations are never charged — you only pay for images you actually receive. (Apify also applies its standard tiny platform fees for the Actor start and each dataset record.)

Tips for great results

• Be specific — describe subject, style, lighting, and mood: "a red fox in a snowy forest at golden hour, cinematic, shallow depth of field".
• For Image to Image, describe the change you want ("turn it into a watercolor", "make it night time"), not the whole scene.
• Use the negative prompt (text-to-image) to suppress artifacts: "blurry, low quality, distorted, extra fingers".
• Keep steps at 4 for the fastest, cheapest results; raise them only if you want extra detail.
• Set a seed to reproduce or iterate on a result you like.

Use it from the API

curl-X POST "https://api.apify.com/v2/acts/danitn11~flux2-klein-image-generator/runs?token=YOUR_TOKEN"\
-H"Content-Type: application/json"\
-d'{ "prompt": "A beautiful sunset over a calm ocean, cinematic", "imageSize": "landscape_16_9" }'

Works the same from the Apify n8n node, Make, Zapier, LangChain, or the Apify MCP server for AI agents.

For the full request/response shape (run-sync, async, polling, downloading the image), see the OpenAPI spec at ./openapi.yaml — import it into Postman, Insomnia, or any OpenAPI client.

Templates & integrations

Drop this Actor into a no-code workflow to automate image creation end to end. In each tool, search for the Apify connector, authenticate with your Apify API token, and select danitn11/flux2-klein-image-generator with the action Run Actor (or Run Actor and get dataset items to receive the image URL back).

• n8n — add the Apify node → Run Actor, map prompt (and imageUrl for editing) from a previous step (e.g. a new row in a Sheet or a form submission), then push the resulting imageUrl to your publishing node.
• Make.com — use the Apify › Run an Actor module, then a Watch / Get dataset items module to read back imageUrl. Chain into Buffer, Google Drive, or a social uploader.
• Zapier — trigger (new row, form submission, etc.) → Apify: Run Actor → action (post to social, save to Drive, send a Slack message).

Common pattern — automated image pipeline:

New prompt(Sheet / form / webhook)
 → Run thisActor(prompt [+ imageUrl])
 → Get imageUrl
 → Post to social / save to storage / attach to a listing

Use with AI agents (MCP server)

This Actor works as a tool for any MCP-compatible AI agent (Claude, Cursor, VS Code Copilot, custom agents) through Apify's hosted MCP server. Your agent can generate or edit images as part of a larger task — "design a thumbnail and post it" — with billing through your Apify account.

Server URL (with this Actor preselected as a tool):

https://mcp.apify.com?tools=danitn11/flux2-klein-image-generator

Authenticate with OAuth (you'll be redirected on first connect) or an Authorization: Bearer <APIFY_TOKEN> header.

Claude Code

$claude mcp add--transport http apify "https://mcp.apify.com?tools=danitn11/flux2-klein-image-generator"-H"Authorization: Bearer <APIFY_TOKEN>"

Claude Desktop / claude.ai — add a custom connector with the server URL above (OAuth flow handles auth).

Cursor / VS Code — add to .cursor/mcp.json (or "MCP: Open User Configuration" in VS Code):

{
"mcpServers":{
"apify":{
"url":"https://mcp.apify.com?tools=danitn11/flux2-klein-image-generator",
"headers":{"Authorization":"Bearer <APIFY_TOKEN>"}
}
}
}

Local stdio (npx)

{
"mcpServers":{
"apify":{
"command":"npx",
"args":["-y","@apify/actors-mcp-server","--tools","danitn11/flux2-klein-image-generator"],
"env":{"APIFY_TOKEN":"<APIFY_TOKEN>"}
}
}
}

Then just ask your agent: "Generate a 16:9 image of a sunset over the ocean, cinematic." The agent calls the Actor, waits for the result, and gets back the image URL from the output schema.

FAQ
