Generate Stunning Images with the RealVisXL 4.0 Cognitive Actions

The RealVisXL 4.0 Cognitive Actions provide developers with powerful tools for generating high-quality, realistic images using advanced AI models. Leveraging the capabilities of the RealVisXL 4.0 model, which builds upon the Stable Diffusion XL architecture, these actions enable customizable image generation tailored to your specific needs. By integrating these pre-built actions into your applications, you can create stunning visuals effortlessly.

Prerequisites

Before you begin using the RealVisXL 4.0 Cognitive Actions, ensure that you have the following:

  • An API key for the Cognitive Actions platform, which you will need to authenticate your requests.
  • A basic understanding of how to make HTTP requests and handle JSON payloads.

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

Cognitive Actions Overview

Generate Realistic Image with RealVisXL 4.0

This action allows you to generate high-quality, realistic images based on a descriptive text prompt. It supports various customizable parameters to refine the output, including dimensions, guidance intensity, and the method for scheduling the image generation process.

Input

The input for this action follows the schema defined below:

{
  "seed": 42,
  "width": 768,
  "height": 1024,
  "prompt": "RAW photo, a portrait photo of a woman in casual clothes, natural skin, tailored black three-piece suit, skin, 8k uhd, high quality, film grain, Fujifilm XT3",
  "scheduler": "DDIM",
  "guidanceScale": 7,
  "negativePrompt": "(deformed iris, deformed pupils, semi-realistic, cgi, 3d, render, sketch, cartoon, drawing, anime:1.4), text, close up, cropped, out of frame, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad anatomy, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck",
  "numberOfPictures": 1,
  "numInferenceSteps": 30
}
  • seed (integer): A random seed for reproducibility (default: 42).
  • width (integer): The width of the generated image in pixels (default: 512).
  • height (integer): The height of the generated image in pixels (default: 768).
  • prompt (string): A descriptive text prompt for guiding image generation.
  • scheduler (string): The scheduler method to use, with a default of "DDIM".
  • guidanceScale (integer): The intensity of prompt guidance (default: 7).
  • negativePrompt (string): Describes unwanted elements to avoid in the generated images.
  • numberOfPictures (integer): The number of images to generate (1 to 4, default: 1).
  • numInferenceSteps (integer): The number of steps for image refinement (default: 20).

Output

Upon successful execution, the action returns a list of URLs pointing to the generated images. Here’s an example of the output:

[
  "https://assets.cognitiveactions.com/invocations/ad44c427-7434-4b6d-8fdc-772edcfe9d0c/b44a087c-c574-486e-b320-e6e30d4a382f.png"
]

Conceptual Usage Example (Python)

Here’s how you might call the Generate Realistic Image action using Python:

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 = "13a823c6-cdcb-4383-9251-521452f8bb94"  # Action ID for Generate Realistic Image

# Construct the input payload based on the action's requirements
payload = {
    "seed": 42,
    "width": 768,
    "height": 1024,
    "prompt": "RAW photo, a portrait photo of a woman in casual clothes, natural skin, tailored black three-piece suit, skin, 8k uhd, high quality, film grain, Fujifilm XT3",
    "scheduler": "DDIM",
    "guidanceScale": 7,
    "negativePrompt": "(deformed iris, deformed pupils, semi-realistic, cgi, 3d, render, sketch, cartoon, drawing, anime:1.4), text, close up, cropped, out of frame, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad anatomy, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck",
    "numberOfPictures": 1,
    "numInferenceSteps": 30
}

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}  # Hypothetical structure
    )
    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 code snippet, replace the placeholders with your actual API key and endpoint URL. The input payload is structured according to the action's requirements, ensuring that all necessary parameters are included.
