A cascaded voice agent just won a blind human-preference ranking against native speech-to-speech models.

Today, Cartesia launched Managed Agents, ranked #1 on Artificial Analysis’ Speech Agent Arena.

Most LLMs learn from chunks of text picked by a tokenizer. But here, H-Nets learn directly from raw bytes and figure out those boundaries themselves.

This leads to 3–5x better efficiency in controlled scaling experiments. At larger scale, matching an open-source model trained on 11 trillion tokens with roughly 10x less training data and compute.

#1 in blind human preference and #1 in enterprise accuracy Cascaded stack that sounds as natural as speech-to-speech Own speech models and agent harness tuned as one system

#1 on @ArtificialAnlys Speech Agent Arena and @ServiceNow EVA-Bench, built by co-designing our voice models and harness as one system.
