DFARS
☆ Shortlist
Quick takeThe short version. Every tile links to the full detail below.
Constant is a direct operator with a broad GPU lineup spanning current-generation NVIDIA capacity. Running its own network, it suits teams moving from experimentation into sustained production or those that need range across training, inference and fine-tuning without managing separate provider accounts.
The tradeoff: procurement is configuration-dependent and may require a quote process rather than instant checkout. Best fit for buyers with a clear workload plan.
Best for: Buyers who want a direct relationship with the operator that owns the metal. Not for: Teams prioritising a marketplace's breadth of third-party supply.
Confidence: HighEvidence reviewed: 6 checks
Confirmed
Network ownership
Constant operates its own network (1.5M IPv4 addresses across 1698 prefixes) rather than presenting another hyperscaler's capacity as its own.
Confirmed
Direct operator classification
Constant controls GPU infrastructure and sells access directly. Not a marketplace or hyperscaler resale offer.
