Vast.ai vs LowCostGPU prices, GPU by GPU
Public on-demand list prices per GPU-hour on Vast.ai's pricing page (2026-09-04) against LowCostGPU's fixed rates today — every LowCostGPU price is the public marketplace median × 0.70, rounded down, re-checked weekly.
| GPU | Vast.ai list | LowCostGPU on-demand | LowCostGPU interruptible | Difference |

Configurations differ (node sizes, tiers, regions); the note beside each card says which Vast.ai price is quoted. Negative differences mean Vast.ai is cheaper on that card.
When to stay with Vast.ai
- The absolute floor price on consumer cards: unverified and community hosts routinely list the RTX 3090, 4090 and 5090 under LowCostGPU's on-demand rate, and interruptible bids go lower still, if host-by-host variance is an acceptable trade-off.
- DLPerf and per-host reliability scores let you shop performance and risk directly, and 68+ GPU types — down to old Pascal and Turing cards — cover configurations no fixed-catalogue cloud stocks.
- 1, 3 and 6-month reserved contracts negotiated directly with a specific host, if locking in one known machine matters more than a uniform fleet.
Why teams switch to LowCostGPU
- Every LowCostGPU instance already clears Vast's own bar for a verified-datacenter host — Tier-III facility, audited uptime — at one fixed price, with no DLPerf shopping or reliability-score checking needed.
- On flagship datacenter cards the fixed price (market median × 0.70) is usually at or below Vast's own verified-host rate: Vast lists the H100 SXM at $2.21/hr and the A100 80 GB at $1.32/hr on verified hosts (checked 2026-09-04); unverified prices below that carry the interruption and data-loss risk Vast's own documentation warns about.
- Storage that is not exposed to a host-set rate billing continuously while stopped: a flat $0.08/GB/month here, the same price on every machine.
- More coins, no processor pass-through: USDT (TRC-20/ERC-20), BTC, XMR, LTC, ETH, TRX and SOL directly, no KYC step — Vast's crypto option runs through BitPay or Crypto.com, which apply their own verification.
Switching from Vast.ai: what maps to what
| On Vast.ai | On LowCostGPU |
|---|---|
| Community / unverified host listing | Instance on a verified Tier-III datacenter — the same bar as Vast's own verified badge, on every machine |
| Datacenter-verified host | Instance — verified is the only tier, at one fixed price |
| Interruptible bid | Interruptible instance, flat −50% |
| Reserved host (1/3/6-month) | Reserved instance, −35% from 3 months |
| DLPerf / reliability score | Uniform hardware baseline, 99.9% SLA on every machine |
| vast CLI / API | lowcostgpu CLI / REST API |

Vast.ai alternative: FAQ
Is LowCostGPU cheaper than Vast.ai?
It depends which part of Vast's market you compare against. On verified-datacenter-host pricing, generally yes: Vast lists the H100 SXM at $2.21/hr and the A100 80 GB at $1.32/hr on verified hosts (checked 2026-09-04), while LowCostGPU fixes both at the public market median × 0.70. On consumer cards, Vast's cheapest unverified and interruptible listings can undercut LowCostGPU — the RTX 4090 has been seen from about $0.29/hr on unverified hosts versus $0.39/hr on Vast's own verified hosts (checked 2026-09-04) — in exchange for the host-by-host reliability risk LowCostGPU does not carry.
What is DLPerf, and do I need to check it on LowCostGPU?
DLPerf is Vast's synthetic deep-learning benchmark score, used to compare real throughput across hosts running the same GPU model, since cooling and power delivery vary machine to machine on a marketplace. LowCostGPU does not publish an equivalent score because every machine sits in the same class of verified Tier-III facility — the variance DLPerf exists to catch is the thing being removed.
Can I still bid for the absolute cheapest GPU-hour like on Vast?
No — LowCostGPU publishes one price per GPU and a flat −50% interruptible tier instead of a bidding system. That is a deliberate trade: no auction to watch, but no path to Vast's occasional rock-bottom unverified listing either.
Does LowCostGPU accept the same payment methods as Vast.ai?
Both take crypto, differently: Vast routes it through BitPay or Crypto.com on top of card-first billing; LowCostGPU is crypto-only — USDT (TRC-20/ERC-20), BTC, XMR, LTC, ETH, TRX and SOL directly, with no card and no KYC at any step.
Try the switch for the price of a coffee
Top up $40 in USDT or Monero, deploy the same image you run on Vast.ai, and benchmark it. No card, no KYC, per-second billing — stop it the minute you are done.
