AI Agent Architectures: From ReAct to Multi-Agent Systems

Introduction: AI agents go beyond simple LLM calls by combining reasoning, planning, tool use, and memory to accomplish complex tasks autonomously. Different agent architectures suit different problems: ReAct agents interleave reasoning and action, plan-and-execute agents create upfront plans, and multi-agent systems coordinate specialized agents. This guide covers building robust agent systems: the ReAct pattern for […]

Serverless AI Architecture: Building Scalable LLM Applications

Three years ago, I built my first serverless LLM application. It failed spectacularly. Cold starts made responses take 15 seconds. Timeouts killed long-running requests. Costs spiraled out of control. After architecting 30+ serverless AI systems, I’ve learned what works. Here’s the complete guide to building scalable serverless LLM applications. Figure 1: Serverless AI Architecture Overview […]
