The short version

  • Only HeyGen has a free tier, so it costs nothing to try first.
  • Each has a real cost: DeepInfra focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.; HeyGen avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds
  • They diverge on capability: DeepInfra covers Open model hosting, HeyGen covers AI avatars.

Where each one falls short

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

DeepInfra

  • Focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.
  • Model selection is limited to what DeepInfra chooses to host, unlike self-managed platforms.
  • No published free tier; usage is billed from the first token.

HeyGen

  • Avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds
  • Cannot reliably choreograph natural interactions like walking through a room, using devices, or drinking from objects
  • Billing gap between marketed unlimited plans and actual credit consumption is highest complaint with lost credits on failed renders
  • Inconsistent lip sync and voice quality with slow processing and occasional moderation blocks without explanation
  • Customer support described as non-existent with no way to complain or reach a human representative
