What Are Agentic AI Frameworks?

Agentic AI frameworks are platforms and toolkits designed to create, orchestrate, and manage autonomous AI agents—typically powered by LLMs or multi-agent systems (MAS)—capable of reasoning, memory, and dynamic task execution. Unlike traditional AI tools, these frameworks emphasize autonomy, persistent memory, workflow orchestration, and integration with external data sources or APIs.

Key Characteristics:

• Autonomous Agents: Agents operate with higher independence, chaining reasoning steps across tasks.
• Orchestration: Manage communication, task allocation, and dependencies between multiple agents or workflows.
• Memory Persistence: Agents often use context windows, vector databases, or custom stores for knowledge retention.
• Integration: Built to work with prominent LLM providers, enterprise systems, and third-party APIs.

Examples of Agentic AI Usage:

• Automating a multi-step business process across different software (e.g., customer support ticket triage)
• Multi-agent research assistants where each LLM agent specializes (e.g., data retrieval, summarization)
• Document intelligence workflows combining retrieval augmented generation (RAG) and multi-modal reasoning
