Frequently Asked Questions
Quick answers to common questions about licenses, installation, and GPU requirements.
How do I activate my $35 Lifetime License?
Open the Cosmic-Gen desktop application on macOS or Windows. Click the Settings icon in the sidebar, select “License”, enter your Gumroad license key, and click “Activate License”. Your unlimited local generation grant will unlock immediately.
Can I use my license on both macOS and Windows?
Yes. A single lifetime license is granted per user and allows you to activate the application on your personal desktop workstations (e.g. your Mac laptop and Windows desktop rig).
Do Cloud GPU credits expire?
No. Cloud credits are non-expiring and strictly pay-as-you-go ($1.00 USD = 100 credits). There are no monthly recurring fees or auto-renewals.
What are the minimum hardware requirements for Local Mode?
Windows requires an NVIDIA GPU with at least 8GB VRAM (RTX 3060 or higher recommended). macOS requires Apple Silicon (M1, M2, M3, or M4) with 16GB or more of unified memory.
