Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fireworks AI

  • Reserved and enterprise-tier pricing is not published and requires sales contact.
  • Model catalog is curated to ~30 models, smaller than DeepInfra's 100+ model library.
  • On-demand GPU rates are scheduled to increase from September 1, adding cost unpredictability for locked-in workloads.

Hetzner Cloud

  • Cost-Optimized plans are shown as currently unavailable
  • The shared-resource tiers are positioned for variable usage and development rather than sustained production workloads
  • Regions are limited to Germany, Finland, the United States and Singapore, so latency to other markets is a real constraint
  • The uptime guarantee is 99.9 percent, below what the large hyperscalers offer on comparable services
  • Support is 24/7 by email, without a phone channel
