# gpt-image-1 > OpenAI's latest image generation and editing model: gpt-1-image. ## Overview - **Endpoint**: `https://fal.run/fal-ai/gpt-image-1/edit-image` - **Model ID**: `fal-ai/gpt-image-1/edit-image` - **Category**: image-to-image - **Kind**: inference ## Pricing Your request will cost different amounts based on the input and output. - You will be charged $0.002 per 1,000 input text tokens. One word is roughly 4 tokens. - You will be charged $0.005 per 1,000 input image tokens. One 1024x1024 image is roughly 135 tokens in low fidelity mode, or 3,050 tokens in high fidelity mode. - For **low** quality, you will be charged $0.011 for 1024x1024 or $0.016 for any other size *per output image*. - For **medium** quality, you will be charged $0.042 for 1024x1024 or $0.063 for any other size *per output image*. - For **high** quality, you will be charged $0.167 for 1024x1024 or $0.25 for any other size *per output image*.

See the input and output schema below, as well as the usage examples. ### Input Schema The API accepts the following input parameters: - **`prompt`** (`string`, _required_): The prompt for image generation - Examples: "Make this pixel-art style." - **`image_urls`** (`list`, _required_): The URLs of the images to use as a reference for the generation. - Array of string - Examples: ["https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk.png"] - **`image_size`** (`ImageSizeEnum`, _optional_): Aspect ratio for the generated image Default value: `"auto"` - Default: `"auto"` - Options: `"auto"`, `"1024x1024"`, `"1536x1024"`, `"1024x1536"` - **`background`** (`BackgroundEnum`, _optional_): Background for the generated image Default value: `"auto"` - Default: `"auto"` - Options: `"auto"`, `"transparent"`, `"opaque"` - **`quality`** (`QualityEnum`, _optional_): Quality for the generated image Default value: `"auto"` - Default: `"auto"` - Options: `"auto"`, `"low"`, `"medium"`, `"high"` - **`input_fidelity`** (`InputFidelityEnum`, _optional_): Input fidelity for the generated image Default value: `"high"` - Default: `"high"` - Options: `"low"`, `"high"` - **`num_images`** (`integer`, _optional_): Number of images to generate Default value: `1` - Default: `1` - Range: `1` to `4` - Examples: 1 - **`output_format`** (`OutputFormatEnum`, _optional_): Output format for the images Default value: `"png"` - Default: `"png"` - Options: `"jpeg"`, `"png"`, `"webp"` - **`sync_mode`** (`boolean`, _optional_): If `True`, the media will be returned as a data URI and the output data won't be available in the request history. - Default: `false` **Required Parameters Example**: ```json { "prompt": "Make this pixel-art style.", "image_urls": [ "https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk.png" ] } ``` **Full Example**: ```json { "prompt": "Make this pixel-art style.", "image_urls": [ "https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk.png" ], "image_size": "auto", "background": "auto", "quality": "auto", "input_fidelity": "high", "num_images": 1, "output_format": "png" } ``` ### Output Schema The API returns the following output format: - **`images`** (`list`, _required_): The generated images. - Array of ImageFile - Examples: [{"width":1024,"height":1536,"content_type":"image/png","url":"https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk_pixel.png","file_name":"cyberpunk_pixel.png"}] **Example Response**: ```json { "images": [ { "width": 1024, "height": 1536, "content_type": "image/png", "url": "https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk_pixel.png", "file_name": "cyberpunk_pixel.png" } ] } ``` ## Usage Examples ### cURL ```bash curl --request POST \ --url https://fal.run/fal-ai/gpt-image-1/edit-image \ --header "Authorization: Key $FAL_KEY" \ --header "Content-Type: application/json" \ --data '{ "prompt": "Make this pixel-art style.", "image_urls": [ "https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk.png" ] }' ``` ### Python Ensure you have the Python client installed: ```bash pip install fal-client ``` Then use the API client to make requests: ```python import fal_client def on_queue_update(update): if isinstance(update, fal_client.InProgress): for log in update.logs: print(log["message"]) result = fal_client.subscribe( "fal-ai/gpt-image-1/edit-image", arguments={ "prompt": "Make this pixel-art style.", "image_urls": ["https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk.png"] }, with_logs=True, on_queue_update=on_queue_update, ) print(result) ``` ### JavaScript Ensure you have the JavaScript client installed: ```bash npm install --save @fal-ai/client ``` Then use the API client to make requests: ```javascript import { fal } from "@fal-ai/client"; const result = await fal.subscribe("fal-ai/gpt-image-1/edit-image", { input: { prompt: "Make this pixel-art style.", image_urls: ["https://storage.googleapis.com/falserverless/model_tests/gpt-image-1/cyberpunk.png"] }, 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); ``` ## Additional Resources ### Documentation - [Model Playground](https://fal.ai/models/fal-ai/gpt-image-1/edit-image) - [API Documentation](https://fal.ai/models/fal-ai/gpt-image-1/edit-image/api) - [OpenAPI Schema](https://fal.ai/api/openapi/queue/openapi.json?endpoint_id=fal-ai/gpt-image-1/edit-image) ### fal.ai Platform - [Platform Documentation](https://docs.fal.ai) - [Python Client](https://docs.fal.ai/clients/python) - [JavaScript Client](https://docs.fal.ai/clients/javascript)
