First input image. Must be jpeg, png, gif, or webp.

input_image_2

*file

Preview

Second input image. Must be jpeg, png, gif, or webp.

aspect_ratio

string

Aspect ratio of the generated image. Use 'match_input_image' to match the aspect ratio of the input image.

Default: "match_input_image"

seed

integer

Random seed. Set for reproducible generation

output_format

string

Output format for the generated image

Default: "png"

safety_tolerance

Safety tolerance, 0 is most strict and 2 is most permissive. 2 is currently the maximum allowed.

Default: 2

Run this model in Node.js with one line of code:

npx create-replicate --model=flux-kontext-apps/multi-image-kontext-max

or set up a project from scratch

Install Replicate’s Node.js client library:

npm install replicate

Set the REPLICATE_API_TOKEN environment variable:

export REPLICATE_API_TOKEN=<paste-your-token-here>

Find your API token in your account settings.

Import and set up the client:

import Replicate from "replicate";
import fs from "node:fs";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,
});

Run flux-kontext-apps/multi-image-kontext-max using Replicate’s API. Check out the model's schema for an overview of inputs and outputs.

const input = {
  prompt: "Put the woman into a white t-shirt with the text on it",
  aspect_ratio: "1:1",
  input_image_1: "https://replicate.delivery/pbxt/N5rSeJrCafWpmJuLb62moY8pSMEpSBBwSf7N6hxyIn4fNYMa/w8msa88d01rm80cq3hzsqrdehg.png",
  input_image_2: "https://replicate.delivery/pbxt/N5rSdTCgBqIRvbkedcfLfS5xTSEEOqMtX9FsR1hLK9JYryml/0_1.webp",
  output_format: "png",
  safety_tolerance: 2
};

const output = await replicate.run("flux-kontext-apps/multi-image-kontext-max", { input });

// To access the file URL:
console.log(output.url()); //=> "http://example.com"

// To write the file to disk:
fs.writeFile("my-image.png", output);
