Vast.ai (live API) — GPU pricing & deliverability
5 tracked offerings · grade mix A:0 · B:0 · C:1 · D:1 · U:3. Public bundles API exposes price, GPU count, VRAM, geolocation and PCIe details per listing, but nothing about inter-node fabric or NVLink topology. Multi-node contiguity is not a marketplace concept here: each listing is a single host.

Grades measure what sellers publish — deliverability of the written claim, not measured performance. No fleet holds a measured (Verified) badge yet; that tier arrives with the verification harness. Source classes: API = provider's live pricing API · vendor = provider's published page · mkt API = marketplace API · 3rd-party = aggregator (provider publishes no price on its own pages) · quote = quote-gated or "starting at", not a walk-up price. Quote-class prices are shown in tables but excluded from headline ranges, spreads, and fair-price bands.
Terms & trust (as published, 2026-09-14)
| Uptime SLA | not published |
| SLA remedy | none stated — ToS affirmatively disclaims availability: 'Company cannot guarantee the Website and that Company Services will be always available' and 'Company shall have no liability whatsoever for any loss...during any downtime'. Credits spent are final and non-refundable; unspent balance refunds at sole discretion. |
| Capacity guarantee | On-demand instances 'Cannot be interrupted' (host-set fixed price); interruptible instances are bid-based and 'Can be stopped by higher bids'; reserved instances offer prepaid discounts (up to 50%) with 'Same priority as on-demand'. No published guarantee that on-demand capacity will be available to start. |
| Egress fees | Host-set per-host bandwidth pricing, shown during instance selection: 'Data transfer costs vary by host and include both upload and download traffic. Charges apply per byte transferred' — charged 'regardless of what state [the instance] is in'. No free-egress claim. |
| Billing granularity | per-second for active rental ('charged...for every second your instance is in the active/connected state'); storage billed continuously including while stopped |
| Self-serve signup | yes — credit cards via Stripe, plus crypto (BitPay, Crypto.com); no sales contact needed for on-demand |
| Security certifications | SOC 2 Type II certified (platform-level); SOC 3 report available on request; HIPAA workloads supported on Secure Cloud tier with BAAs 'available for qualifying customers'. Docs say Secure Cloud providers are vetted datacenters with ISO 27001 / Tier 3-4 standards, but compliance page caveats partner certs 'are encouraged...but are not strictly required'. |
Notes: Marketplace: no uptime SLA anywhere; the substitute is (1) per-second billing only while active and (2) host 'reliability scores' — verification requires reliability over 90% and unstable machines are auto-deverified, but this is a historical score, not a contractual commitment. Tier distinction: 'Secure Cloud' = certified/vetted datacenter partners (Tier 3/4, HIPAA-eligible) vs community/unverified hosts where 'Provider security varies significantly'.

Reliability record
Vast.ai (live API) publishes no machine-readable incident history (status page: https://status.vast.ai). We track every provider's public status feed weekly; a seller you cannot audit for downtime is a seller whose SLA you cannot price. Absence is a finding.
