GlirOSRequirements
What your PC and browser need
GlirOS has no hard minimum except Windows: it fits the AI model to your PC. This page says what we recommend for the Windows app and for the web version, and what each one can do.
The Windows app
The app runs the models on your own PC, on the graphics card when it has one.
Windows
Windows 11, or Windows 10 version 2004 (build 19041) or later, on a 64-bit Intel or AMD PC (x64). PCs with an ARM processor can't run the app; they can use the web version. On Windows 10 the window has a plain title bar.
Microsoft Edge WebView2
The app shows its window with WebView2. Windows 11 has it. On Windows 10, GlirOS offers Microsoft's download if it is missing.
Memory
16 GB of memory is recommended. With less, GlirOS picks a smaller model: Qwen 3.5 2B runs on a PC with 4 GB of memory.
Disk space
The models take the space: 1.9 to 15.4 GB each for the ones GlirOS suggests, 17 to 23 GB for the larger ones on its list. Keep about 5 GB free for a small model, and 20 GB or more if you want larger ones. Each model is downloaded once and checked before it is used.
Installing
GlirOS.exe installs itself in your own user folder: no admin rights and no separate installer. It isn’t signed with a certificate Windows trusts yet, so Windows names an unknown publisher and may say Windows protected your PC; choose More info, then Run anyway.
Internet
Only to download models, and for what you switch on: web search, cloud models and online tools. Once its models are downloaded, the app works offline.
Which model GlirOS suggests
When you first start the app, it checks your PC and suggests a model; you can pick another in Settings > Models. Only a separate graphics card's own memory counts as graphics memory. Built-in graphics share the PC's ordinary memory.
| Your PC has | GlirOS suggests | Download |
|---|---|---|
| A graphics card with 12 GB or more | Gemma 4 26B A4B, partly in the PC's memory: the larger models | 15.4 GB |
| A card with 10 to 11 GB | Gemma 4 12B | 7.4 GB |
| A card with about 9 GB | Qwen 3.5 9B | 6.6 GB |
| A card with 8 GB | Gemma 4 E4B: better answers, still quick | 5.2 GB |
| A card with 6 GB, like many gaming laptops | Qwen 3.5 4B | 3.4 GB |
| A card with about 4 to 5 GB | Qwen 3.5 2B | 1.95 GB |
| No graphics card, 16 GB of memory or more | Qwen 3.5 4B, on the processor or the built-in graphics: it works, only slower | 3.4 GB |
| No graphics card, less memory | Qwen 3.5 2B | 1.95 GB |
GlirOS suggests only models it has tested. How fast a model answers depends on your PC: Settings > Benchmark measures it on yours. Making pictures, video and voices needs more: on a small card, GlirOS may set the chat model aside while it makes a picture. A PC without a graphics card
Graphics drivers
This is our advice, not a measurement. GlirOS uses the graphics card through Vulkan, so an up-to-date driver gives it the best chance of using your card.
Update it from the maker
Before the first model download, update the driver from the graphics maker and restart the PC: NVIDIA (the NVIDIA app, or nvidia.com/drivers), AMD (AMD Software: Adrenalin Edition, or amd.com/support), Intel (Intel Driver & Support Assistant, or intel.com). If in doubt, use your PC maker's support page.
Stable, not beta
Choose the latest stable driver, not a beta. Windows Update offers drivers too, but they are often older. Never use a driver-download site or a tool that scans for drivers.
See that it works
In GlirOS, Settings > Models says Runs fast on your graphics card for a model that fits, and the loaded model shows how many of its layers are on the GPU. GlirOS doesn't show the driver version: Windows' Device Manager or the maker's app does.
Videos on an NVIDIA card
Making videos with an NVIDIA card's own encoder needs driver 610 or newer. With an older driver GlirOS uses another encoder and says so.
The web version
The web version runs in the browser, with nothing to install. It is for trying GlirOS and for using it from a phone; the full app is the Windows app.
Models in the browser
The web version's models run on the graphics card through WebGPU, from Qwen 3.5 2B (suggested, about 1.4 GB) to Qwen 3.5 9B (about 5.4 GB). A current Chrome or Edge on a computer has WebGPU. Each model is downloaded once into the browser; clearing the site's data removes it.
Without WebGPU
Where the browser has no WebGPU, the models say Can't run in this browser. GlirOS Helper (Lite) still runs on the processor in every modern browser, more slowly, and a cloud model works with your own API key.
Built-in graphics
On a PC with only built-in graphics, GlirOS asks before it loads a model there, because it can make the PC slow. The other ways are High performance in Windows Settings > System > Display > Graphics, or GlirOS Helper (Lite).
Phones, tablets and Macs
There is no Mac, Android or iPhone app; the web version works on them in the browser. Phones are weak for models of their own, so on a phone the best way is to open your own PC with remote access, or to use a cloud model. Remote access needs Chrome 137, Safari 17 or Firefox 129, or newer.
Only in the Windows app
The larger models on your graphics card, project folders, connectors (MCP), Research and the AI media add-ons are in the Windows app only.
