SwiftVR is an open-weight model for video to video from H Oliday, released under Apache License 2.0. It has 5B parameters. At 16-bit it needs about 12 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index. It draws 969 downloads a month.
SwiftVR is a streaming one-step generative video restoration (VR) framework presented in SwiftVR: Real-Time One-Step Generative Video Restoration.
Runs On
What it takes to serve SwiftVR (5B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.
| Precision | Weights | Memory needed | Cheapest setup | Per hour | Also fits |
|---|---|---|---|---|---|
| 16-bit | 10.0 GB | 12.0 GB | 1x MI300X (192 GB) Vultr |
$1.85 | 1x H100 $1.99 · 1x MI325X $2.00 |
| 8-bit | 5.0 GB | 6.0 GB | 1x MI300X (192 GB) Vultr |
$1.85 | 1x H100 $1.99 · 1x MI325X $2.00 |
| 4-bit | 2.5 GB | 3.0 GB | 1x MI300X (192 GB) Vultr |
$1.85 | 1x H100 $1.99 · 1x MI325X $2.00 |
Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 24, 2026.

SwiftVR: Real-Time One-Step Generative Video Restoration
SwiftVR is the first generative video restoration model to reach real-time 1080p streaming on a consumer-grade GPU (≈26 FPS on a single RTX 5090), sustains 31 FPS at QHD (2560×1440) and 14 FPS at 4K (3840×2160) on a single H100, and streams at resolutions where every compared diffusion-based VR baseline runs out of memory.

Questions About SwiftVR
How much GPU memory does SwiftVR need?
About 12 GB at 16-bit and 3 GB at 4-bit: the weights (5B parameters) plus a working margin. A long context needs more.
What is the cheapest GPU to run SwiftVR on?
At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.
