Contribute
See what your PC can do
The network runs on PCs like yours. The local check estimates a hardware tier, then tells you what that tier can host today.
- Windows 10/11 64-bit today. macOS and Linux are not supported yet.
- 8 GB RAM minimum; a 4 GB GPU helps, and a 4-core CPU can still contribute.
- You choose whether the worker runs, the idle-only wait, and active hours. The app enforces those settings locally; CPU, GPU, temperature, and bandwidth ceilings are not exposed in this build.
The check runs locally. Nothing is uploaded until you ask for an invite.
Contribution is invite-only. There is no public signup.
Local check
Check this PC
Four quick steps estimate the tier this PC can host. The check runs in your browser.
We read
- Browser
- Graphics adapter or CPU
- Memory estimate
- Operating system
The check runs locally. Nothing is uploaded until you ask for an invite.
The browser can't read exact VRAM. The Windows app confirms it after install.
What we detect
Browser and operating system, a graphics adapter string or CPU core count, an approximate memory size, and WebGPU/WebGL support. No hardware strings leave this page.

Benchmarking
Running the local benchmark
A fixed workload runs in a local worker. No network requests, no model weights, no uploads.
Elapsed 0s Up to 20 seconds. You can cancel at any time.
This check pauses if the tab is hidden for more than 5 seconds.

Check paused
The tab was hidden for more than 5 seconds, so the local check stopped. Nothing was uploaded.

Your result
Best fit
LFM3-1.7B
Estimated from browser signals; the native app is authoritative.
Low confidence: the browser could not confirm a precise memory value.
Detected specs
Nothing was uploaded. The native worker app is authoritative.
Manual route
Enter specs manually
Use the numbers you know. This is a low-confidence estimate; the Windows app re-checks the machine after install.
Nothing is stored on a server. A coarse tier and timestamp may be saved in this browser after a result appears.
Requirements
What a worker PC needs
Minimums are per worker, not per request. The native app re-checks them before install.
| Operating system | Windows 10/11 64-bit |
|---|---|
| System RAM | 8 GB minimum |
| Graphics | 4 GB VRAM or CPU |
| Disk space | ~5 GB available (LFM3 + app) |
| Network | Broadband; unmetered preferred |
Invite and install
Install after an invite
Invited contributors receive the Windows installer and a one-time enrollment token by email. The installer is not publicly linked until it is code-signed.
There is no public installer download, no account signup, and no API key creation on this page.
What the invite covers
- The model and role the worker will serve.
- A one-time enrollment token, bound to the install.
- The limits the worker must respect on the machine.
Do not forward the email or share the token. The operator sends both manually.
You’re on the list.
We’ll email you when access opens.
Control and safety
You keep control
The worker runs only while its limits allow it. You can stop at any time.
-
Pause any time
Stop accepting jobs without uninstalling the app. The worker leaves the scheduling pool.
-
Schedule and idle limits
Choose whether contribution is enabled, the idle-only wait, and active hours. The app enforces those settings locally. CPU, GPU, temperature, and bandwidth ceilings are not exposed in this build.
-
Idle-only option
Accept work only while the PC is idle, so daily tasks keep their headroom.
-
Schedule windows
Choose the hours the worker may accept jobs. Outside them, it stays offline.
-
Uninstall and clear
Remove the app and its local data. The invite and enrollment token are not reused.
-
Electricity stays yours
A working GPU or CPU draws more power. You cover the electricity; credits are not live.
Do I need a dedicated GPU?
No. LFM3-1.7B runs on CPU with 8 GB RAM and 4+ cores. A 4–7 GB GPU moves the estimate to the entry tier. CPU workers run at lower throughput and lower priority.
Can I contribute from a laptop?
Sometimes. A laptop with 8 GB RAM and 4+ cores can host LFM3, but thermals and power limits matter. The browser estimate is coarse; the native app confirms the machine.
Does the browser check certify my PC?
No. It estimates a tier from browser signals. Exact VRAM and model load are checked by the Windows app after install, and that check can revise the tier.
