The short version

  • Only Replika has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lambda Labs on demand capacity is first come access rather than guaranteed, so an instance type can be unavailable when needed; Replika pricing not published on main website or pricing page
  • They diverge on capability: Lambda Labs covers NVIDIA GPUs, Replika covers Conversational AI.
  • Prices and features above were last checked on 30 August 2026.
