Edit images using Bytedance's Seedream 5.5 model.
The client provides a convenient way to interact with the model API.
npm install --save @fal-ai/clientSet FAL_KEY as an environment variable in your runtime.
export FAL_KEY="YOUR_API_KEY"The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.
import { fal } from "@fal-ai/client";
const result = await fal.subscribe("bytedance/seedream/v5.5/edit", {
input: {
prompt: "Replace the product in Figure 1 with that in Figure 2. Seamlessly render the logo in Figure 3 into the product design, in a frosted glass texture.",

},
logs: true,
onQueueUpdate: (update) => {
if (update.status === "IN_PROGRESS") {
update.logs.map((log) => log.message).forEach(console.log);
}
},
});
console.log(result.data);
console.log(result.requestId);The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.
import { fal } from "@fal-ai/client";
fal.config({
credentials: "YOUR_FAL_KEY"
});The client API provides a convenient way to submit requests to the model.
import { fal } from "@fal-ai/client";
const { request_id } = await fal.queue.submit("bytedance/seedream/v5.5/edit", {
input: {
prompt: "Replace the product in Figure 1 with that in Figure 2. Seamlessly render the logo in Figure 3 into the product design, in a frosted glass texture.",
image_urls: ["https://storage.googleapis.com/falserverless/example_inputs/seedreamv45/seedream_v45_edit_input_1.png", "https://storage.googleapis.com/falserverless/example_inputs/seedreamv45/seedream_v45_edit_input_2.png", "https://storage.googleapis.com/falserverless/example_inputs/seedreamv45/seedream_v45_edit_input_3.png"]
},
webhookUrl: "https://optional.webhook.url/for/results",
});You can fetch the status of a request to check if it is completed or still in progress.
import { fal } from "@fal-ai/client";
const status = await fal.queue.status("bytedance/seedream/v5.5/edit", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
logs: true,
});Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.
import { fal } from "@fal-ai/client";
const result = await fal.queue.result("bytedance/seedream/v5.5/edit", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.
You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.
You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.
We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.
import { fal } from "@fal-ai/client";
const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);Read more about file handling in our file upload guide.
prompt string* requiredThe text prompt used to edit the image.
The size of the generated image. Total pixels must be between 921600 and 4624220, with aspect ratio between 1/16 and 16. Default value: auto_2K

"image_size": {
"width": 1280,
"height": 720

output_format OutputFormatEnumThe file format of the generated image. Default value: "png"
