Topaz Video AI Anime Upscaling: Full Gaia Model Review & Comparison with UniFab Kairo Model

What Is Topaz Anime?

Topaz Anime refers to the anime-focused upscaling capabilities within Topaz Video AI, a widely acclaimed AI video enhancer developed by Topaz Labs. Rather than offering a standalone “Topaz Anime” product, the company integrates its anime upscaling engine—primarily the Gaia model—into the broader Topaz Video AI workflow.

Gaia: Topaz Video AI Anime Upscaling Model

The core of Topaz Video AI’s anime functionality centers on its Gaia model. Gaia model distinguishes itself as a dedicated high-quality (HQ) animation upscaling engine within the Topaz ecosystem. Using proprietary deep neural networks trained specifically on animation and CG footage, Gaia promises to amplify crisp lines, revive faded colors, and enhance frame-to-frame consistency without introducing excessive artifacts or shimmer. 

Best Topaz Settings for Anime

Users can adjust several advanced parameters:

• Add Noise: Adds fine digital grain before enhancement, which can sometimes help preserve texture or counteract excessive smoothing.
• Focus Fix: Downscales and then re-upsizes input to counteract blurriness in sources, with “Normal” and “Strong” presets for varying degrees of correction.
• Input Video Type: Lets users specify if the material is “High Quality” (live footage) or “Computer Generated” (animation/3D), ensuring optimal processing for anime-style works.

These parameter settings give users a granular degree of control. However, as we’ll discover in our benchmarks, more control does not always equate to better ultimate results.

Gaia's Performance on Real-World Anime Footage

To move beyond marketing claims and evaluate how Topaz Gaia performs in practical workflows, we tested it on a real-world anime clip under controlled conditions.

Test Environment & Footage

Test Machine:

• GPU: NVIDIA GeForce RTX 4070
• CPU: AMD Ryzen 7 5700G with Radeon Graphics

Test Footage: A 1 minute 59 second anime source video at 30fps and 720×720 resolution, with slightly blurry details such as character outlines and clothing folds, and minor edge aliasing.

Processing Target: Upscale the footage to 3840×2160 (4K) resolution.

Topaz Anime Upscaling Effect Analysis

When processing the 720×720 anime source to 4K on our RTX 4070 rig, Topaz Gaia delivered a mixed performance that aligns with our earlier observations.

• Artifact Smoothing: The model effectively reduced compression blockiness and minor edge aliasing, resulting in a cleaner, more polished base for the upscaled output.
• Line Sharpness Trade-off: While compression artifacts were smoothed, the overall image retained a slight softness. Thin black character outlines and clothing details, such as the folds on the characters' pants, were not fully reconstructed to the razor-sharp definition that anime fans often prefer. In some areas, these lines appeared to blur slightly into the background, rather than standing out crisply.
• Style Preservation: Gaia maintained the original color palette and cartoon art style without introducing unnatural "plastic" textures or color distortion. The character proportions and facial features remained stable, avoiding the warping that can occur with less specialized models.

In summary, Topaz Gaia excels at noise and artifact reduction, creating a visually cleaner image. However, for this 720×720 to 4K workflow, it does so at the expense of the crisp line work that is a hallmark of quality anime upscaling, making it a strong choice for artifact removal but less ideal for hyper-detailed reconstruction.

Real-World User Perspectives on Topaz Gaia

While Topaz markets the Gaia model as a solution for anime upscaling, real-world user feedback from the official Topaz Labs community paints a more critical picture. One user, identified as sinan.saymaz and labeled as a "TOPAZ VIDEO AI OWNER," stated bluntly:
"The Gaia model doesn’t improve quality at all. In fact, it tends to make it worse. Here is the proof of it:"
— sinan.saymaz, Topaz Labs Community Forum

This sentiment aligns with our own observations: when processing 720×720 anime footage to 4K, Gaia excels at smoothing compression artifacts but often sacrifices the crisp line work that anime fans prioritize, resulting in an overall softer, less detailed output that can feel like a step backward rather than an improvement.

Topaz Gaia vs UniFab Anime Model—The Ultimate Comparison

UniFab's Anime Model at a Glance

While Topaz has long been a leading name in AI upscaling, UniFab Video Upscaler AI’s Kairo Model has quickly gained attention among video professionals and hobbyists alike. UniFab positions its Anime Model not just for restoration, but for real-time enhancement of animation with a user-friendly interface. The Kairo Model, in particular, is engineered to preserve both linework and color saturation, often addressing the very shortcomings we noted with Gaia.

Real-Word Test on Visual Quality

Our empirical tests using identical clips revealed marked differences when upscaling anime to 4K. For a 1min59s, 30fps, 720×720 source upscaled to 3840×2160, Gaia’s output appeared noticeably soft, especially in intricate patterns and thin linework.

In contrast, UniFab’s Kairo Model offered noticeably crisper edges, denser black levels, and no visible loss of small details.

In summary: UniFab’s Kairo Model consistently outperforms Topaz Gaia in both sharpness and texture retention, with noticeably better clarity in direct side-by-side anime upscaling comparisons.

Real-Word Test on Processing Speed

Performance doesn't just end with picture quality—processing speed is a key deciding factor for many users. Our benchmarks document a clear pattern: UniFab's Anime Model almost always finished first.

Testing three representative samples:

💡 In two out of three typical real-world cases, UniFab doubled Gaia’s speed—an especially valuable distinction for anyone batch processing or working under tight deadlines.

Pricing Comparison

When it comes to investing in an AI upscaling solution for anime, price and licensing flexibility weigh heavily.

In summary: For dedicated anime enhancement, UniFab’s flexible licensing and lifetime options provide a much lower barrier to entry and long-term ownership.

Final Verdict: Choose Topaz Anime or UniFab Anime Model?

Which is the best anime upscaler? After dozens of test runs, it’s clear: if your goal is purely anime upscaling, UniFab's Kairo Model delivers better detail, faster processing, and dramatically lower long-term costs compared to Topaz Gaia. Its ease of use lowers the entry barrier for both beginners and long-time fans.

FAQs about Topaz Anime

How does Topaz Video AI anime upscaling work for animated videos?

Topaz Video AI anime upscaling works by using specialized AI models trained to recognize animation-specific features such as clean line art, flat colors, and sharp edges. Instead of treating anime like live-action footage, the AI focuses on edge refinement, anti-aliasing, and artifact reduction, which are critical for animation quality.

The typical workflow includes:

• Importing the anime clip into Topaz Video AI
• Selecting an appropriate AI model (commonly Proteus or Gaia CG)
• Manually adjusting parameters like sharpness, detail recovery, and de-haloing
• Previewing multiple frames to avoid over-processing
• Exporting the upscaled video, often followed by compression with tools like HandBrake

This approach allows users to upscale anime to higher resolutions (1080p or 4K) while preserving the original art style.

What are the best Topaz settings for animes?

The best Topaz settings for animes focus on preserving clean line art, flat colors, and sharp edges without introducing noise or grain. Most users recommend using Proteus (Manual) or Artemis HQ, depending on source quality.

Commonly recommended settings include:

• AI Model: Proteus (Manual) or Artemis HQ
• Denoise: Very low (around 5–10%)
• Sharpen: Low (5–10%) to avoid harsh outlines
• Detail Recovery: Medium to high for clearer line work
• Grain: 0 (anime does not benefit from added grain)

These settings help enhance clarity while maintaining the original anime art style.
