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
Vapi pros and cons
Full control over the voice stack (STT, LLM, TTS, telephony)
Low-latency, near-human real-time conversations
Flexible REST API and official SDKs for any language
Advanced features like Squads, function calling, and RAG
Headline $0.05/min excludes provider costs, so real cost is much higher
Pricing is hard to predict and budget across multiple vendors
Steep learning curve for non-developers
