Retell tops $100M run rate, launches Tell 1 voice model
A voice-AI vendor shipping its own foundation model signals a shift from reselling general-purpose LLMs to owning the speech-to-reasoning stack, which could compress latency and cost for high-volume call operations. Contact-center engineering and CX teams evaluating voice-agent platforms should benchmark Tell 1 against general models like GPT-4o on latency and failure rates. Conductor's automated test-case generation also gives teams a concrete workflow for continuous agent quality control.
