Real ESRGAN

Real-ESRGAN with optional face correction and adjustable upscale

Features

Real-ESRGAN is an advanced image super-resolution model developed by nightmareai, now available through WaveSpeedAI. It enhances image clarity and resolution, making it ideal for restoring low-quality or blurry photos.

Key Features

• Image Enhancement: Improves image clarity and resolution.
• Fast Inference with WaveSpeedAI: Delivers rapid processing speeds.
• Cost-Effective Deployment: Offers affordable usage rates.

ComfyUI

nightmareai/real-esrgan is also available on ComfyUI, providing local inference capabilities through a node-based workflow. This ensures flexible and efficient video generation on your system, catering to various creative workflows.

Limitations

• Artifact Introduction: May produce artifacts in certain scenarios.
• Out-of-Distribution Challenges: Less effective on unfamiliar degradations.
• Resource Requirements: High-resolution processing demands significant GPU memory.

Out-of-Scope Use

The model and its derivatives may not be used in any way that violates applicable national, federal, state, local, or international law or regulation, including but not limited to:

• Exploiting, harming, or attempting to exploit or harm minors, including solicitation, creation, acquisition, or dissemination of child exploitative content.
• Generating or disseminating verifiably false information with the intent to harm others.
• Creating or distributing personal identifiable information that could be used to harm an individual.
• Harassing, abusing, threatening, stalking, or bullying individuals or groups.
• Producing non-consensual nudity or illegal pornographic content.
• Making fully automated decisions that adversely affect an individual’s legal rights or create binding obligations.
• Facilitating large-scale disinformation campaigns.

Accelerated Inference

Our accelerated inference approach leverages advanced optimization technology from WavespeedAI. This innovative fusion technique significantly reduces computational overhead and latency, enabling rapid image generation without compromising quality. The entire system is designed to efficiently handle large-scale inference tasks while ensuring that real-time applications achieve an optimal balance between speed and accuracy.
