Generate realistic images with the RealVisXL_V4.0 model hosted on HuggingFace. RealVisXL 4.0 is a highly advanced image generation AI model designed for photorealistic outputs. It’s built on the Stable Diffusion XL (SDXL) architecture and fine-tuned to create images with exceptional detail and realism.

​
Getting Started

​
Steps

  1. In your Edge Impulse project, choose Data acquisition > Synthetic data.
  2. Select the ‘Huggingface RealVisXL_4.0 Synthetic Image Generator’ block, fill in your prompt and label, and hit Generate data.
    You need a HuggingFace API Key/Access Token. See below to create one and set the permissions.
  3. Your synthetic data will show on the right side, for quick evaluation of your prompt.

Generate an Access Token in Hugging Face

See https://huggingface.co/docs/hub/en/security-tokens for more information. To create an Access Token in the Hugging Face web interface, click on your avatar (top-right corner) and select Settings. Navigate to the Access Token view (left menu) and click on New token. Add a Name and for the Type use the “Fine-grained (custom)” option. Copy the newly generated Access Token Finally, add the following permissions:
  • Make calls to the serverless Inference API
  • Make calls to Inference Endpoints

Limitations and warnings

  • The model is still in the training phase. This is not the final version and may contain artifacts and perform poorly in some cases.
  • The model can produce NSFW (Not Safe For Work) images!
