Sierra: how many tokens per task, and what does it cost?
Sierra publishes no per-task cost or token figure in the AgentBurn index. AgentBurn snapshot 2026-10-27. Every figure carries a provenance label: source-backed, derived, or left empty when no public basis exists.
What it is. Outcome-priced customer agents that own the whole resolution
Sierra builds customer-facing agents across chat, voice and email that connect to CRMs, order systems and data warehouses and complete actions rather than just answer questions. Pricing is outcome-based and negotiated per resolved conversation, so the interesting metric is cost per resolution instead of cost per token.
