Sierra Agent OS

Sierra Agent OS is an enterprise platform for building and running conversational AI agents that handle customer interactions autonomously or alongside human representatives. It uses a "constellation of models" architecture that orchestrates multiple foundation models from providers like OpenAI, Anthropic, and Meta to handle different aspects of conversations. The platform includes Agent Studio for no-code agent building, an Agent SDK for developer-driven agent creation with composable skills and guardrails, a data layer called Agent Data Platform that gives agents persistent memory and access to enterprise systems like billing and CRM, and Live Assist which provides real-time AI guidance to human care representatives. Agents can be deployed as a single instance across chat, voice, email, SMS, WhatsApp, ChatGPT, and contact centers, with outcome-based pricing tied to value delivered.
