Retell AI pros and cons
Transparent per-minute, pay-as-you-go pricing with no platform fee
Full feature access from day one, nothing locked behind higher tiers
Strong developer tooling: API, testing/simulation suite, webhooks, functions
Wide model and voice choice (GPT, Claude, ElevenLabs, Retell voices)
Headline $0.07/min rate is misleading; real costs run $0.13-$0.31/min
Costs stack across LLM, TTS, and telephony, making budgeting complex
Enterprise plan is expensive, starting around $8,000
Sesame pros and cons
Exceptionally natural, human-like voices with breaths, pauses and emotion
Voices can be interrupted and respond in real time
Free to try via browser and mobile preview
Open-source CSM-1B model available for developers under Apache 2.0
Still an early preview and research product, not a polished mainstream app
Access and features are limited and can change without notice
Primarily English-focused, with limited multilingual support
