Student Credits — $20 free credit (A6000/L40 only) high confidence
Official /students page (read 2026-10-22): sign up with your student email to get $20 of free Thunder Compute credit, added automatically after signup ('no application and no waiting'). Credit is restricted to RTX A6000 and L40 GPUs — at listed on-demand rates (A6000 $0.35/hr, L40 $0.79/hr) that is ~57 A6000-hours or ~25 L40-hours. Not usable on H100 SXM ($3.20/hr) or A100 80GB ($1.09/hr).
Eligibility
Students enrolled at US universities only ('Only students enrolled at US universities qualify'). Must sign up with a university email; the system 'verify your email domain automatically'. No other credential (not even strictly .edu, though the company's own blog FAQ phrases it as 'verified .edu email') is stated. No credit card or payment method is mentioned as required to claim the credit; after it is exhausted, standard pay-as-you-go billing applies.
How to claim
1) Sign up at console.thundercompute.com/signup using your university email; 2) email domain is verified automatically and the $20 credit is added to the account right after signup; 3) use the credit on A6000 or L40 instances. No application, no waiting.
Expiry
No expiration date, renewal cycle, or re-eligibility window is stated on the /students page. After the credit is spent, usage continues at normal pay-as-you-go rates.
Gotchas
US-institution-only; credit locked to A6000/L40 (cheapest GPUs in their lineup, not the H100/A100 most workloads need); fraud or abuse 'may result in credit removal or account suspension'. One account/student implied by the auto-verification; no stated way to re-claim. WebSearch was unavailable this session (budget exhausted), so a 2025-2026 history of the offer (e.g., whether it was ever larger or previously also covered A100) could not be verified.
Referral Program — 3% of referred customers' lifetime spend, paid in credits high confidence
Official /referrals page (read 2026-10-22): 'Earn 3% in credits on the lifetime spend of every customer you refer to Thunder Compute.' Example given: refer $10,000 in spend -> $300 in credits. Recurring/ongoing, not one-time. Referring 25 users who spend money unlocks affiliate status. No dollar cap or per-referral limit is stated beyond the illustrative example.
Eligibility
Open to any Thunder Compute user (no student/startup-specific tier, region or startup-age criterion stated). Payout is Thunder Compute credits, not cash.
How to claim
Share your referral link; each referred paying customer generates 3% of their lifetime spend as credit to your account.
Expiry
No expiry stated; credit accrues for the lifetime of referred customers' spend.
Gotchas
Credits only, not cash. 'Fraud or abuse of the referral program may result in credit removal and/or account suspension.' You need referrals who actually spend; a referred free-credit-only student account generates no referral value unless they top up. Not a startup program — it's a generic growth incentive.
As of 2026-10-22 Thunder Compute has no free tier, no trial credits, and no startup program: /startup and /changelog both 404; the pricing page lists only paid on-demand rates (A6000 $0.35/hr, L40 $0.79/hr, A100 80GB $1.09/hr, H100 SXM $3.20/hr; sandbox GPUs H100 $2.95/GPU-hr and A100 $1.95/GPU-hr; data egress $0.00/GB; disk $0.219/GB/mo) with a reserved/volume-pricing mention that is discounted committed spend, not free; the sign-up page (console.thundercompute.com/signup) mentions no promotional credit. The company's own 'Free Cloud GPU Credits in 2026' blog directory attributes to Thunder Compute only the $20 student credit and the 3% referral program — no startup-tier entry. So there is no evidence a startup program ever existed or was sunset; the only distinct free offers are the student credit and the referral credits above. Caveat: WebSearch's session budget was exhausted, so 2025-2026 change history was verified by reading official pages only, not by news search.
