Controlnet QR Pattern (QR Codes) - A Stable Diffusion-based model designed to generate artistic QR codes with enhanced scannability.

## Primary Function of Controlnet QR Pattern The primary function of the Controlnet QR Pattern (QR Codes) model is to generate artistic QR codes that remain scannable. It achieves this by conditionally controlling the processing of the closest black and white pixels (25% each) to maintain QR code integrity while integrating artistic elements. ## Compatible Base Model The Controlnet QR Pattern (QR Codes) model is compatible with the Stable Diffusion 1.5 (SD 1.5) base model. ## Recommended Parameters Recommended parameters for the Controlnet QR Pattern (QR Codes) model include: - **Base model**: meinamix v8 - **Steps**: 30 - **Image size**: 1024x1024 - **ControlNet settings**: - Preprocessor: none - Weight: 1 - Start/end control: (0, 0.8) - Control mode: Balanced - **ADetailer steps**: 36 (for facial detail enhancement). ## ADetailer Functionality ADetailer is an extension supported by the Controlnet QR Pattern (QR Codes) model that improves facial details in generated images. It is particularly useful for artistic QR codes containing human faces, ensuring finer details and higher visual quality. ## Artistic Integration Challenges The artistic integration of QR codes may appear unnatural because the model prioritizes scannability by focusing on the closest black and white pixels (25% each). This can limit the seamless blending of artistic elements, requiring parameter adjustments for optimal results. ## Rounded QR Code Tool The model recommends using [qrcode.antfu.me](https://qrcode.antfu.me/) to generate rounded QR codes, which tend to produce better artistic results. ## Supporting the Creator Users can support the creator, an Argentine student, through their [ko-fi page](https://ko-fi.com/nacholmo). The model is provided as a free community resource, and contributions help sustain open-source development. ## Model Statistics and Metadata Key statistics and metadata for the Controlnet QR Pattern (QR Codes) model include: - **Release date**: July 7, 2023 - **Last update**: November 16, 2024 - **Type**: ControlNet - **Usage stats**: 25,528 downloads - **Base model**: SD 1.5 - **Hash**: AutoV2, F0648652D7. ## Workflow for Unscannable Output If the initial QR code output is unscannable, users should: 1. Generate multiple images with varied parameters. 2. Adjust ControlNet weight, steps, or image size. 3. Use ADetailer for facial detail refinement. 4. Refer to the [full guide](https://antfu.me/posts/ai-qrcode-101) for additional optimization tips. ## Alternative Models Yes, some users recommend QRCode Monster as an alternative to Controlnet QR Pattern (QR Codes), particularly for balancing scannability and artistic style. The choice depends on specific use-case requirements. ### Citation sources: - [Controlnet QR Pattern (QR Codes)](https://civitai.com/models/90940/controlnet-qr-pattern-qr-codes) - Official URL Updated: 2025-04-01
