Project Overview

OmniAgent is an enterprise-grade AI customer support agent capable of ingesting thousands of internal PDF documents, API specs, and past ticket histories to resolve complex technical queries autonomously.

The Challenge

The client was drowning in 5,000+ repetitive support tickets weekly, resulting in 24-hour response delays and skyrocketing human support payroll.

The Architecture Solution

We engineered a sub-second Retrieval-Augmented Generation (RAG) pipeline utilizing Pinecone vector indexes, GPT-4o contextual synthesis, and automated Google Calendar API scheduling.

Technical Architecture Highlights

  • Vector embeddings generated via text-embedding-3-small with metadata chunking.
  • Hybrid keyword and semantic search layer ensuring 99.8% factual retrieval accuracy.
  • FastAPI asynchronous streaming endpoints handling 500+ concurrent chats.
  • Automated human-in-the-loop fallback when confidence drops below 85%.

Key Features & Capabilities
