Retell AI

Key facts: Retell AI shipped Tell-1 on November 12, 2026, a voice model for live contact-centre calls with interleaved reasoning, alongside a new Dialer product for outbound campaigns.

It is pay as you go, with no minimums and no contracts, and the first 20 simultaneous calls are free.

Plans: Pay as you go: $0.07–$0.31 a minute for AI voice agents, depending on the voice and model you pick. Tell-1 Beta costs $0.035 a minute as the LLM, and $0.011 per AI message for chat agents. Sign up free with $10 of starter credit. Enterprise is custom pricing.
