The short version

  • Each has a real cost: Modal the Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute; 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: Modal covers Serverless GPUs, Replika covers Conversational AI.

Where each one falls short

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

Modal

  • The Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute
  • Compute is billed per second across separate GPU and CPU meters, so total cost depends on execution time rather than any fixed rate
  • The Starter plan's $30 monthly free credit is the only allowance below the paid base fee
  • Enterprise volume discounts are custom and unpublished

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.
