Cartesia Pricing
Cartesia · Voice Agents & Speech/Audio
Voice AI research lab building state-of-the-art speech synthesis models (Sonic) with ultra-low latency (<100ms). Usage-based pricing: pay-per-character generation, entry rate around $0.017/1K characters. Enterprise custom for volume. Popular with voice agent developers who need faster-than-ElevenLabs synthesis for real-time conversations.
In other words, Cartesia is worth it for developers building real-time voice agents where sub-100ms TTS latency matters (voice interruption handling, conversational feel). Sonic model is competitive with ElevenLabs on quality and faster on latency. Usage-based pricing keeps it flexible for developer teams. Downside: newer than ElevenLabs, smaller voice library, less known outside the voice-AI developer community.
