NeuroStream & NeuroServer — Local Rendering for Large Models
As our models have grown more powerful, so have their hardware demands. The best results were increasingly locked behind extremely powerful GPUs, limiting how many users could actually take advantage of them locally. As those requirements kept growing, we knew we needed to rethink how we build, deliver, and run these models. That rethinking led to NeuroStream.
NeuroStream is a proprietary, industry-first technology that reduces VRAM requirements by up to 95%, allowing large models like Wonder 2 and Wonder 3 to run on everyday hardware without sacrificing output quality. The only tradeoff is a minor reduction in processing speed. What once required an extremely powerful GPU accessible only on the cloud can now run on the hardware most users already have.
To use NeuroStream technology on your device we’ve built NeuroServer. This lightweight local server runs on your machine when you select a model that requires it. Topaz Gigapixel will automatically spin up NeuroServer in the background, load the model, and process your images. When it’s no longer needed, the server shuts down on its own.
This opens a new chapter for what’s possible in Topaz Gigapixel. NeuroStream removes the biggest barrier to running powerful models locally, and we’re already working on bringing more models to the application using this technology. We’re excited about what’s ahead as we break down barriers for AI processing.
Wonder 2 Local Render — Photorealistic Recovery, Now Running Locally
Wonder 2 quickly became a fan favorite after its launch, delivering artifact-free enhancements, reliable text preservation, and our most powerful realistic recovery to date. The catch was that Wonder 2’s resource demands meant it could only run in the cloud.
That changes today.
With the introduction of NeuroStream and NeuroServer, we’ve built the infrastructure to bring Wonder 2 to your local machine. These technologies allow larger, more demanding models to run directly on your device and Wonder 2 is the first to take advantage of them.
Local rendering is currently supported on:
- NVIDIA GPUs: 8GB VRAM or more
- AMD GPUs: 8GB VRAM or more
- Apple Silicon: 16GB RAM, macOS 14 or later
Intel Mac and Windows ARM (Snapdragon) users will continue to use cloud render for Wonder 2. Cloud render supports output up to 100MP.
For supported hardware, you can choose between local and cloud render depending on your preference. The two models have a slightly different character: the local model renders a bit sharper and less grainy than the cloud version, with particularly strong handling of faces and skin detail. If portraits are a big part of your workflow, it’s worth trying both and seeing which look you prefer.
With local rendering now available, you can process
