Generate Stunning High-Resolution Images with ByteDance's Res-Adapter Actions

In today’s digital landscape, the ability to create high-quality visuals is crucial for applications across various industries. The ByteDance Res-Adapter provides developers with powerful Cognitive Actions designed to generate consistent high-resolution images using diffusion models. These pre-built actions streamline the image generation process, allowing you to produce stunning visuals without the need for extensive training or complex adjustments.

Prerequisites

To get started with the ByteDance Res-Adapter Cognitive Actions, you will need:

• An API key for the Cognitive Actions platform.
• Basic familiarity with JSON and making HTTP requests.

Authentication typically involves passing your API key in the headers of your requests.

Cognitive Actions Overview

Generate Consistent High-Resolution Images

Description:
This action enables the generation of high-resolution images that exceed the trained resolution domain of diffusion models without requiring further training or inference adjustments. It's a versatile tool for enhancing image quality seamlessly.

Category: image-enhancement

Input

The input for this action follows the schema defined as CompositeRequest. Here are the key fields:

• seed (integer, optional): Random seed for generating images. Leave blank to use a randomized seed.
  Example: 42
• width (integer, optional): Width of the output image in pixels. Default is 1024.
  Example: 1024
• height (integer, optional): Height of the output image in pixels. Default is 1024.
  Example: 1024
• prompt (string, required): Text prompt guiding the image generation.
  Example: "Female in a fantasy world, Fluid brushwork, Bright colors..."
• modelName (string, optional): Select a Stable Diffusion model. Default is 'dreamlike-art/dreamlike-diffusion-1.0'.
  Example: "dreamlike-art/dreamlike-diffusion-1.0"
• showBaseline (boolean, optional): Show a comparison baseline without the Res-Adapter applied. Default is true.
  Example: false
• guidanceScale (number, optional): Scale for classifier-free guidance. Range is 0 to 20, default is 7.5.
  Example: 7.5
• negativePrompt (string, optional): Specify undesired elements in the output image.
  Example: "NSFW, poor bad amateur assignment cut out ugly"
• resAdapterAlpha (number, optional): Alpha parameter for the Res-Adapter. Must be between 0 and 1. Default is 0.7.
  Example: 0.7
• numInferenceSteps (integer, optional): Number of steps for denoising during image generation. Default is 25.
  Example: 25

Example Input

{
  "seed": 42,
  "width": 1024,
  "height": 1024,
  "prompt": "Female in a fantasy world, Fluid brushwork, Bright colors, Emphasis on light and atmosphere...",
  "modelName": "dreamlike-art/dreamlike-diffusion-1.0",
  "showBaseline": false,
  "guidanceScale": 7.5,
  "negativePrompt": "NSFW, poor bad amateur assignment cut out ugly",
  "resAdapterAlpha": 0.7,
  "numInferenceSteps": 25
}

Output

The action returns a URL to the generated image, as well as a reference to a baseline image if requested.

• with_res_adapter: URL of the generated image using the Res-Adapter.
  Example: https://assets.cognitiveactions.com/invocations/...
• without_res_adapter: URL of the baseline image (if applicable).
  Example: null

Example Output

{
  "with_res_adapter": "https://assets.cognitiveactions.com/invocations/2c15ba47-9ef7-4dad-9ca9-d420abda06dc/0c9dd859-3b4d-46f9-adef-48a06bc4c9e2.png",
  "without_res_adapter": null
}

Conceptual Usage Example (Python)

Here’s how you might implement this action in your application:

import requests
import json

# Replace with your Cognitive Actions API key and endpoint
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute" # Hypothetical endpoint

action_id = "b88cd748-46ea-4873-9208-4db74ce9c272" # Action ID for Generate Consistent High-Resolution Images

# Construct the input payload based on the action's requirements
payload = {
    "seed": 42,
    "width": 1024,
    "height": 1024,
    "prompt": "Female in a fantasy world, Fluid brushwork, Bright colors...",
    "modelName": "dreamlike-art/dreamlike-diffusion-1.0",
    "showBaseline": False,
    "guidanceScale": 7.5,
    "negativePrompt": "NSFW, poor bad amateur assignment cut out ugly",
    "resAdapterAlpha": 0.7,
    "numInferenceSteps": 25
}

headers = {
    "Authorization": f"Bearer {COGNITIVE_ACTIONS_API_KEY}",
    "Content-Type": "application/json"
}

try:
    response = requests.post(
        COGNITIVE_ACTIONS_EXECUTE_URL,
        headers=headers,
        json={"action_id": action_id, "inputs": payload}
    )
    response.raise_for_status() # Raise an exception for bad status codes (4xx or 5xx)

    result = response.json()
    print("Action executed successfully:")
    print(json.dumps(result, indent=2))

except requests.exceptions.RequestException as e:
    print(f"Error executing action {action_id}: {e}")
    if e.response is not None:
        print(f"Response status: {e.response.status_code}")
        try:
            print(f"Response body: {e.response.json()}")
        except json.JSONDecodeError:
            print(f"Response body: {e.response.text}")

In this example, you replace YOUR_COGNITIVE_ACTIONS_API_KEY with your actual API key. The action ID for generating consistent high-resolution images is referenced, and the payload is constructed to match the required input schema.
