Topaz Wonder 2 (now runs locally in Topaz Photo): Wonder 2 is our newest image enhancement model that denoises, sharpens, and upscales in a single step, with no sliders or tuning required. It is a giant, powerful model that now runs locally thanks to our proprietary NeuroStream technology, which dramatically reduces VRAM usage and allows powerful AI to run on standard creator hardware.

Topaz Astra update: Astra now includes Starlight Fast 2, along with new scene detection and batch rendering. These updates allow creators to enhance videos faster and process multiple files more efficiently, making Astra more powerful for real-world workflows.
Additional information:
DALLAS, March 3, 2026 – Topaz Labs, the leader in AI-powered image and video enhancement, today announced Topaz NeuroStream, a proprietary VRAM optimization that allows complex AI models to be run on consumer hardware. This announcement comes alongside a new local image enhancement model, Wonder 2 (Local), that would not be possible without NeuroStream optimization.
Designed as foundational technology, NeuroStream will not be limited to only Topaz Labs models in the future, and has the power to change local AI model use across the entire image and video industry.
“We envision a world where AI models are simply on your device—no cloud needed, no additional usage costs, no specialized hardware, and no security gaps” says Topaz Labs CEO Eric Yang. “Our pro customers have been asking for this since we launched our first large, generative model. And now, we’re very excited to make it a reality.” Without rendering costs, NeuroStream democratizes the use of large AI models. “Creators shouldn’t need specialized hardware or complex workflows to achieve professional results.”
Optimized for NVIDIA Hardware
With a focus on local processing, Topaz Labs has collaborated with NVIDIA to optimize NeuroStream. Very few consumer systems can run a large video model, but with NeuroStream implemented, that same model can be used on every NVIDIA GeForce RTX and RTX PRO GPU.
“As the demand for local processing on RTX GPUs continues to grow, NeuroStream provides an opportunity to run complex AI models on nearly all hardware,” said Gerardo Delgado Cabrera, director of product for AI PCs at NVIDIA. “This latest collaboration with Topaz Labs is part of ongoing efforts to help develop technology optimized for use with NVIDIA-powered devices.”
About NeuroStream: Industry-First VRAM Optimization
NeuroStream is a proprietary technology that reduces VRAM usage by up to 95%, enabling large, complex AI models to run locally on consumer-grade GPUs without sacrificing performance, speed, or output quality. This breakthrough dramatically expands hardware compatibility, democratizing advanced image and video enhancement models previously limited to high-end systems or cloud-only usage.
About Wonder 2 Local: Denoise, Sharpen & Upscale Instantly
Announced in January 2026, the Wonder 2 model represents a fundamental shift in AI image enhancement. It is the first model to denoise, sharpen, and upscale an image simultaneously, eliminating the need for multiple tools, sequential processing, or parameter tuning. Wonder 2 (Local) is now available in Topaz Photo.
