# Final2x

> Final2x is an Electron desktop app over a PyTorch backend (Final2x-core, built on the cccv library) that upscales images with built-in super-resolution models or custom ones. Desktop builds exist for Windows (also winget and Scoop) and macOS; Linux users install the Python backend with pip and PyTorch. Code is BSD-3-Clause, but the README does not state licences for the bundled weights or any hardware requirements. No face restoration or plugins. Active: v4.1.0 released Sep 2026.

## What it replaces
- Topaz Gigapixel: Photo upscaling up to 16x (partial). Plain model-based upscaling; no face recovery, generative models or editor plugins.

## Facts, with sources

| Question | Status | Answer | Source | Checked |
|---|---|---|---|---|
| Runs on my machine? | Confirmed | Yes, desktop app with a local Python backend | https://github.com/EutropicAI/Final2x/tree/main/core | 2026-10-16 |
| Code licence | Confirmed | BSD-3-Clause | https://github.com/EutropicAI/Final2x/blob/main/LICENSE | 2026-10-16 |
| Model weights licence | Unknown | README permits built-in and custom models, but no complete per-weight licence inventory was found in the README or model registry; BSD-3-Clause code licensing alone does not establish all model terms | https://github.com/EutropicAI/Final2x#readme | 2026-10-16 |
| Commercial use | Unknown | BSD-3-Clause covers the code; permission for commercial use of every selectable built-in or custom weight remains unverified. Check the chosen model's upstream licence | https://github.com/EutropicAI/Final2x#readme | 2026-10-16 |
| Paid services needed? | Confirmed | None required | https://github.com/EutropicAI/Final2x#readme | 2026-10-16 |
| Hardware | Unknown | Not documented; backend needs PyTorch 2.0+ | none found | - |
| Operating systems | Confirmed | Windows, macOS, Linux (Linux via pip backend) | https://github.com/EutropicAI/Final2x#readme | 2026-10-16 |
| Setup effort | Confirmed | Easy on Windows and macOS (release download, winget, Scoop); Linux needs Python, PyTorch and pip | https://github.com/EutropicAI/Final2x#-installation | 2026-10-16 |
