Executive Summary

The field of autonomous AI agents and self-improving systems has experienced explosive growth in 2024-2025, with the market reaching $5.4 billion in 2024 and projected to grow at 45.8% annually through 2030.

Core Architectural Patterns

The latest research reveals several key architectural patterns for autonomous agents:

Multi-Agent Orchestration
