Accelerate Image Generation with ByteDance Hyper FLUX 8-Step Actions

In the realm of digital content creation, the ability to generate high-quality images efficiently can significantly enhance the user experience. The ByteDance Hyper FLUX 8-step action set provides developers with powerful tools to leverage advanced image synthesis techniques. By utilizing a state-of-the-art diffusion model, these Cognitive Actions allow you to create stunning visuals with adjustable parameters, making it easier than ever to integrate image generation into your applications.

Prerequisites

Before you start using the Hyper FLUX 8-step Cognitive Actions, ensure you have the following:

  • An API key for the Cognitive Actions platform. This key is essential for authentication when making requests.
  • Familiarity with basic JSON structure as the input and output of these actions will be in JSON format.

Authentication typically involves including your API key in the request headers.

Cognitive Actions Overview

Generate Image with Hyper FLUX 8-step

This action allows you to utilize the ByteDance Hyper FLUX 8-step diffusion model for accelerated image synthesis. You can customize various parameters, including image dimensions, aspect ratio, and output quality.

Category: image-generation

Input:

The input for this action is structured as follows:

  • prompt (required): A string describing the desired image content.
    • Example: "a dog smiling and looking directly at the camera, wearing a white t-shirt with the word \"HYPER\" printed on it."
  • seed (optional): An integer to set a random seed for reproducible generation. Default is 0.
  • width (optional): An integer representing the width of the generated image. Must be a multiple of 16 and only applicable when aspect_ratio is set to custom.
  • height (optional): An integer representing the height of the generated image. Must be a multiple of 16 and only applicable when aspect_ratio is set to custom.
  • aspectRatio (optional): A string indicating the aspect ratio for the generated image. Default is 1:1. Options include 1:1, 16:9, 21:9, etc.
  • outputFormat (optional): A string specifying the file format for output images. Options are webp (default), jpg, png.
  • guidanceScale (optional): A float value guiding the diffusion process. Ranges from 0 to 10, with a default of 3.5.
  • outputQuality (optional): An integer indicating compression quality for output images, ranging from 0 (lowest) to 100 (highest). Not applicable to .png format.
  • numberOfOutputs (optional): An integer to specify how many images to generate (1-4). Default is 1.
  • disableSafetyChecker (optional): A boolean to disable the safety checker. Default is false.
  • numberOfInferenceSteps (optional): An integer that controls the number of inference steps (1-30). Default is 8.

Example Input:

{
  "prompt": "a dog smiling and looking directly at the camera, wearing a white t-shirt with the word \"HYPER\" printed on it.",
  "aspectRatio": "1:1",
  "outputFormat": "webp",
  "guidanceScale": 3.5,
  "outputQuality": 80,
  "numberOfOutputs": 1,
  "numberOfInferenceSteps": 8
}

Output: The action returns a list of URLs pointing to the generated images.

Example Output:

[
  "https://assets.cognitiveactions.com/invocations/096493f1-a5a5-47d5-84f9-b04442c2bd73/be294b53-6a55-4969-af0a-099c4e9aa0f3.webp"
]

Conceptual Usage Example (Python): Here’s how you might call the Hyper FLUX 8-step 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 = "205e3b29-5a8e-4442-a909-af92a3925d71" # Action ID for Generate Image with Hyper FLUX 8-step

# Construct the input payload based on the action's requirements
payload = {
    "prompt": "a dog smiling and looking directly at the camera, wearing a white t-shirt with the word \"HYPER\" printed on it.",
    "aspectRatio": "1:1",
    "outputFormat": "webp",
    "guidanceScale": 3.5,
    "outputQuality": 80,
    "numberOfOutputs": 1,
    "numberOfInferenceSteps": 8
}

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 YOUR_COGNITIVE_ACTIONS_API_KEY with your actual API key. The payload variable is structured according to the action's schema, and the request is sent to the specified endpoint.
