- Discounted pricing based on volumes
- Fully managed agent setup
- Additional included concurrency
- Early access to beta features
- Higher limit on Knowledge Bases
- Custom concurrent calls based on volumes
- Premium private Slack channel support with dedicated support teams

GPT-4.1 Pricing:
GPT-4.1 costs $0.045/minute, with a Fast Tier option at $0.0675/minute. [(1) ](
) This is in addition to the Conversation Voice Engine cost, which ranges from $0.07-$0.08/minute depending on whether you use Elevenlabs/Cartesia voices ($0.07/minute) or OpenAI voices ($0.08/minute) .
Total Cost Calculation:
Your total per-minute cost = Conversation Voice Engine + LLM + Telephony. For example, using GPT-4.1 with Elevenlabs voices and Retell Twilio telephony would be approximately: $0.07 (voice engine) + $0.045 (GPT-4.1) + $0.015 (telephony) = $0.13/minute base rate.
Volume Scaling:
Teams using Retell report cutting call-handling costs by up to 80% compared to traditional IVR systems, thanks to its pay-per-minute model and auto-scaling infrastructure. [(3) ](
