The short version

  • Only Fireworks AI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog consumption-based pricing model makes costs hard to predict and can scale quickly; Fireworks AI reserved and enterprise-tier pricing is not published and requires sales contact.
  • They diverge on capability: Datadog covers Infrastructure monitoring, Fireworks AI covers Serverless inference.

Where each one falls short

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

Datadog

  • Consumption-based pricing model makes costs hard to predict and can scale quickly
  • Add-on modules significantly increase costs: custom metrics, indexed spans, extended retention
  • No free tier for production monitoring
  • High costs for organizations with large amounts of log data or high-cardinality metrics

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.
