Introduction

The failure of Retrieval-Augmented Generation (RAG) in enterprise support has become too costly to ignore. In 2024 alone, over $2.3B was spent on RAG implementations - yet more than 87% failed to achieve meaningful resolution outcomes. The root cause? RAG retrieves content, not answers, and certainly not actions.

This whitepaper introduces Sophie, a RAGless, agentic AI architecture built from first principles to resolve, not just respond. Rather than rely on fuzzy search across knowledge bases, Sophie reasons through structured workflows, invokes deterministic tools, and operates within auditable guardrails to deliver precise, policy-aligned outcomes.

At the core is a Flow-First Execution Framework, where user queries are categorized into subflows based on structured attributes - not just LLM interpretation. Each step of reasoning is governed by enterprise logic, enforced through guardrails, and executed via tool-specific Skill Modules. Every decision is logged via a Traceability Layer and evaluated using CXACT, our open-source framework for agent benchmarking.

Sophie redefines what it means to “automate support.” It’s not about faster deflection. It’s about reliable resolution at scale - measurable, trusted, and real.
