AI Agent & RAG System Em Produção

Agentic Knowledge System.

Multi-agent autonomous framework for document understanding and automated action planning

// overview

Sobre Este Projeto

Agentic Knowledge System

This project demonstrates a robust architecture for deploying autonomous agents that can:

  1. Retrieve Information: Efficiently query vector databases for semantic search.
  2. Reason: Use chain-of-thought prompting to synthesize answers from multiple sources.
  3. Act: Execute tools to fetch real-time data or perform calculations.

Key Features

  • Multi-Agent Orchestration: Uses a supervisor agent to delegate sub-tasks to specialized worker agents.
  • Dynamic Tool Selection: Agents can choose from a suite of tools based on the user query.
  • Self-Correction: Implements a feedback loop where agents can critique and refine their own outputs.

Technology Stack

  • Framework: LangChain & LangGraph
  • Vector DB: Pinecone
  • LLM: GPT-4-turbo / Claude 3 Opus
  • Backend: FastAPI

Funcionalidades Principais

Multi-Agent Orchestration

High

Hierarchical supervisor pattern that delegates complex queries to specialized sub-agents (retriever, calculator, and writer).

LangGraph Python

Dynamic Tool Integration

Medium

Equips agents with search engines, database query runners, and math parsers to ground answers in factual data.

LangChain APIs

Vector-Based RAG Context

High

Advanced chunking and ingestion pipelines with semantic vector search for precise document context extraction.

Pinecone Embeddings
// highlights

Destaques Técnicos

AI Orchestration

State Machine Routing

Utilized LangGraph to model agent interactions as state machines, resolving loops and endless loops typical in LLM routing.

Database Optimization

Hybrid Semantic Search

Implemented Pinecone namespace isolation and metadata filtering, improving document search relevance by 35%.

Arquitetura do Sistema

Padrão Arquitetural

Hierarchical Multi-Agent Architecture

A centralized Supervisor Agent receives requests, breaks them down, triggers parallel worker agents in a directed acyclic graph (DAG), and synthesizes the final response.
