Strengths	+ Ultra-low latency text-to-speech optimized for realtime interaction + State space model architecture aimed at efficiency at scale + Cloud, on-premise, and on-device deployment options + Voice cloning and conversion capabilities	+ Vendor-neutral pipeline with pluggable STT, TTS, and LLM providers + Composable frame/pipeline architecture for custom voice flows + Multiple transport options including Daily WebRTC, LiveKit, and WebSockets + Permissive BSD-2-Clause license
Tradeoffs	− Proprietary models limit portability compared with open-weight options − Usage-based agent minutes add cost on top of base credits − Newer ecosystem than longer-established voice vendors	− Pipeline and frame abstractions take time to learn before simple bots feel simple − Latency and reliability depend heavily on the chosen providers and transport, which you must tune yourself
