- AI agents are core components of modern AI systems, differing from traditional workflows by being autonomous and capable of complex task automation.
- AI agents utilize LLMs as their 'brain', tools as 'weapons' for extended capabilities, and memory for context retention and personalization.
- Memory in AI agents is categorized into short-term (within the context window) and long-term (external storage like vector databases) to manage information efficiently.
- The ReACT framework (Reasoning and Action) enables agents to interact with environments through a loop of Thought, Action, Observation, enhancing problem-solving abilities.
- Agentic patterns include ReACT, Evaluator-Optimizer (Reflection), Tool Use, and Multi-Agent systems, each serving different purposes from task automation to collaborative problem-solving.
- Multi-agent systems can operate via subagents (centralized orchestration), skills pattern (on-demand context loading), handoffs (task delegation), or router pattern (agent selection based on request).
- Workflow patterns like Prompt Chaining, Routing, Parallelization, and Orchestrator-Workers optimize task handling by breaking down problems into manageable subtasks.
- Choosing between AI agents and workflows depends on the need for flexibility and adaptability versus predictability and consistency in task execution.
- Future directions include enhancing context management, evaluation strategies, reliability, security, observability, cost-performance optimization, and implementing guardrails for AI agents.
