Free GPU credits

Lium is a GPU marketplace: H100s, H200s, B200s and RTX cards from many providers, billed per second with no minimum rental, so a small credit goes a long way. These are the ways to get credit today.

$5 when you sign up

  1. Create a Lium account.
  2. Click the verification link we e-mail you. The $5 lands on your balance; on a company or other less common e-mail domain it waits until you add a card.
  3. Rent a GPU with it within 14 days, when it expires.
One credit per person. Signups that look automated, or that come after the day's credit budget is spent, get no credit.

Refer & Earn

Every account has a referral code. You earn 5% for 3 months, then 2.5% for 3 months of each referred account's top-ups, and withdraw it to your Lium balance or a crypto wallet. Your code, link and earnings are on Refer & Earn; listing Lium on a site is covered on Partners.

Credit for startups, research and open source

Building something that needs more GPU time than the signup credit? Ask us. There is no fixed amount: we look at each request, and credit we grant is free credit on your account that expires within 90 days.
  1. Sign up for a Lium account.
  2. E-mail support@lium.io from that account's address with what you are building, a link to it (site, paper or repository), and the GPU model and hours you need.
  3. We reply by e-mail, and any credit we grant lands on your balance.
