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.
Microsoft Azure
- The 12 months of free services is available only to new customers who have not previously had an Azure account or received 12 months of free services
- The 12 months free offer is not available to customers who sign up directly for pay as you go in China and India
- Customers who try Azure free must move to pay as you go within 30 days to keep receiving the 12 months of free services
- Free services are capped at specified monthly amounts, and only some of them are always free
