The short version

  • Only Replika has a free tier, so it costs nothing to try first.
  • Each has a real cost: Firebolt compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop; Replika the App Store listing confirms Replika (Luka, Inc.) is free to download with core messaging available at no cost, but premium features are gated behind in-app purchases with no price figures disclosed in the listing.
  • They diverge on capability: Firebolt covers Sub-second Queries, Replika covers Conversational AI.
