What happened
SiriusXM uses Sierra to run a generative AI customer service agent named Harmony. It handles subscriber requests such as refreshing an in-car radio, making a payment, and updating billing information through natural conversation.
Summary written by usedby from the source page, in English. The figures are those of Sierra and SiriusXM, not ours.
Sierra and SiriusXM worked quickly to understand the set of needs and build a highly-tailored AI agent, affectionately called Harmony. Harmony soon aligned to SiriusXM’s business requirements and began testing top use cases in production.
When customers can have a natural conversation instead of filling out a form, they can be more specific about what they need, and they often share helpful feedback with us as well.
