The best place to find AI Upscaling models
OpenModelDB is a community driven database of AI Upscaling models. We aim to provide a better way to find and compare models than existing sources.

90s Sonic 2x (Small)
by pokepress
Model designed for upscaling footage from Adventures of Sonic the Hedgehog and Sonic SatAm (sorry Sonic Underground fans). These shows (produced by separate contractors/production companies) aired from 1993-1994. While they do consist of cel-based animation, some segments use panning to achieve > 24fps, so you'll probably want to use QTGMC to deinterlace if you're looking for maximum quality.

StarSample V2.0 Lite NS
by .derpy.
This is a model for the restoration of My Little Pony: Friendship is Magic, however it also works decently well on similar art.
V2.0 greatly improves upon V1.0's dataset in every way, taking models from (realistically) only being viable at 1x, to now being far more competent at 2x, more so for the models trained with heavier architectures in this release.
Improvements come as a significantly better understanding of compressions, and partly architecturally/partly dataset improved handling of details and overall understanding of content, leading to less artifacting and "AI smudging". The dataset takes from a larger variety of sources, despite being smaller than V1.0 (when tiled V1.0 would be 71,876 pairs), due to being filtered for IQA scores and detail density. It also contains many thousands of image pairs manually created to cover areas where there wasn't sufficient information.
This release also includes "NS", or "No Scale" models, which are a better representation of my initial goal with StarSample, and (StarSample V2.0 NS) should provide great 1x restoration results with little apparent artifacting, even where the heavier 2x models can fail due to having to increase resolution.

Archiver AntiLines
by Loganavter
A specialized model from the Archivist suite, designed to remove linear artifacts. It excels at eliminating horizontal lines that other denoisers often mistake for part of the line art.
This model is optimized for input resolutions between 720p and 1080p. Using it on significantly different resolutions may produce suboptimal results.
All Archivist models are trained on a custom dataset generated by a physics-based degradation simulator. Recommended Workflow: Use Archivist to fix physical defects, then pass the result through DRUNet (low strength) to stabilize.

Archiver Medium
by Loganavter
A general-purpose model from the Archivist suite, providing a balanced approach to removing common film grain and dirt while preserving the original drawing texture. It is the recommended starting point for most footage.
This model is optimized for input resolutions between 720p and 1080p. Using it on significantly different resolutions may produce suboptimal results.

Archiver RGB
by Loganavter
A specialized model from the Archivist suite, specifically tuned for tackling heavy chromatic (color) noise and severe color channel degradation, often seen in Metrocolor films. Note: its capabilities overlap with the Rough model, but it is better suited for color-based artifacts.
This model is optimized for input resolutions between 720p and 1080p. Using it on significantly different resolutions may produce suboptimal results.

Archiver Rough
by Loganavter
An aggressive restoration model from the Archivist suite for severely degraded footage. It attempts to reconstruct heavily damaged or lost details through hallucination. Note: its capabilities overlap with the RGB model, but it focuses more on structural integrity than color noise.
This model is optimized for input resolutions between 720p and 1080p. Using it on significantly different resolutions may produce suboptimal results.
