About clarity-upscaler

Clarity-Upscaler is a free and open-source artificial intelligence tool designed to enhance and increase the resolution of digital images. It serves as an accessible alternative to paid services like Magnific, offering advanced upscaling capabilities for various use cases including anime, patterns, and general photography. The software supports multi-step upscaling processes and can generate outputs up to 13k by 13k pixels in multiple formats such as JPG, PNG, and WebP. Key features include specialized models for anime and Flux-based upscaling, support for custom safety tensors and LoRa models, and options for image sharpening and fractality adjustments. Users can integrate the tool through several methods: a web application, a REST API for developer integration, a ComfyUI node for workflow automation, or directly via Cog for command-line execution. While the core codebase is open-source and community-driven, the developer also provides optimized, non-open-source versions via their commercial platform for adv

👋 Hello

I build open source AI apps. To finance my work i also build paid versions of my code. But feel free to use the free code. I post features and new projects on https://twitter.com/philz1337x

🔎 Upscaling with Flux

Flux Upscaling is now available at ClarityAI.co/flux-upscaler and is not open-source

It supports Flux LoRas with a style or a face
It's very good at faces, text, art, and generating error-free images

🚀 Options to use Clarity-Upscaler

Note that this repository is an implementation for cog. If you are not familiar with cog, I recommend the easier solutions. The free options are ComfyUI and A1111, while the paid but easy-to-use options are my app ClarityAI.co and the ComfyUI API Node.

🧑‍💻 App

The simplest option to use Clarity is with the app at ClarityAI.co

⚙️ API

To integrate Clarity Upscaler with an API into your application use: ClarityAI.co/API

🐰 ComfyUI

1. API node

Open ComfyUI Manager, search for Clarity AI, and install the node.
Create an API key at: ClarityAI.co/ComfyUI
Add the API key to the node as a) envirement variable CAI_API_KEY OR b) to a cai_platform_key.txt text file OR c) in api_key_override field of the node.

Full instructions: https://github.com/philz1337x/ComfyUI-ClarityAI

2. Free workflow

Download the repo https://github.com/philz1337x/ComfyUI-ClarityAI and use the file free-wokflow.json

🕵️‍♂️ Cog

If you are not familiar with cog read: cog docs

run download_weights.py
predict with cog:

cog predict -i image="link-to-image"

🤹‍♂️ A1111 webUI
