Everything you need to know about GPU HOURS. Buy, use, sell or gift GPU hours priced in USDG on Robinhood Chain. Build without limits.
What is an hour
One GPU hour is the compute of one RTX-4090-class GPU for one hour. Everything in the Studio is priced in hours from what the job actually costs at wholesale, so an hour buys a consistent basket: roughly 40 short essays of chat, 300 images, or one hour of a private endpoint that is yours alone.
Hours are prepaid service credits, like a gift card for compute. They never expire. They are not an investment and pay no yield.
Pricing
Retail is 1.20 USDG per hour. The market bid, what you get when you sell an hour back, is 1.14 USDG. Both follow real GPU rental markets with a 24-hour lag, so the price you see today is the price you get today.
- Chat: about 0.025 h per 1,000 words in and out, model dependent.
- Images: 0.003 h standard, 0.006 h high quality.
- Private endpoint: 1 h per hour, billed while running, stops at zero.
The price index on the Foundry page is information about rental markets, not a promise about hours.

Providers
Inference is bought wholesale through OpenRouter. GPU rentals come from RunPod and Vast. Jobs inherit each provider's acceptable-use policy; anything they refuse, we refuse.
Regions
Hours themselves are not geo-restricted. Paying from NVDA or other stock tokens means a swap in your own wallet first, and that leg follows the stock tokens' own rules: not available to persons in the US, UK, Canada or Switzerland.
Refunds
Refunds are given for jobs that were paid for and not delivered. A failed job never deducts hours. There is no refund for hours you simply decided not to use, because they never expire.
