Pros & Cons

Retell AI

  • Modular pricing allows choosing the right LLM and TTS combination for specific quality/cost needs
  • Enterprise custom pricing can reduce costs to as low as $0.05/minute at high volume
  • No mandatory base subscription — usage-based pricing starting at $0.07/minute
  • Real total cost ($0.13-$0.31/minute) is significantly higher than the advertised $0.07/minute base rate
  • Multiple separate fees (phone numbers, concurrent call slots) add complexity to cost estimation
  • Advanced LLM models (like Claude 3.5) add meaningfully to per-minute cost
