Our take
Pick Smallest.ai if you're voice-stack builders who will spend $10 credits, then $0.09–$0.21 / min. Pick Vapi if you're a builder who want a voice agent with a Dashboard plus an API, and will pay hosting + provider pass-through. Skip Smallest.ai if you're a creator who want a $6 one-time MP3 pack (Narakeet). Skip Vapi if you're on a team that want one all-in per-minute rate with LLM/STT/TTS included (Bland).
