Cartesia's cascaded voice agents top the Speech Agent Arena, beating native speech-to-speech
rohanpaul_ai · x · 2026-10-31
Cartesia launched Managed Agents, an enterprise voice agent platform ranked #1 on Artificial Analysis' Speech Agent Arena (1115) and ServiceNow's EVA-Bench. Its cascaded stack won blind human preference over native speech-to-speech models. H-Nets learn directly from raw bytes, self-determining boundaries — 3–5x efficiency gains in scaling tests and matching an 11T-token open-source model with 10x less data and compute.
