Top 7 Agentic AI Frameworks To Know in 2025

Artificial Intelligence (AI) is entering a new era where systems can act autonomously, reason through problems, and work together like professional teams. AI is no longer just about producing answers. Agentic AI is the name of this emerging field.

The world has moved from GenAI to AI Agents and now to Agentic AI. While GenAI is a type of artificial intelligence that focuses on creating text, images, and audio based on the command (also known as a prompt) by the user, AI agents come into the picture when LLMs start interacting with the tools, memory, and APIs to fetch real-time data. Agentic AI, on the other hand, solves complex workflows without much human intervention and uses single or multiple AI agents.

This transformation of independent decision-making is possible because of agentic AI frameworks. These specialized development platforms give structure to powerful Large Language Models (LLMs), enabling them to interact with tools & APIs, maintain memory, plan multiple steps, and even collaborate as a group of agents.

In this blog, we explain what agentic AI is, the 7 key agentic AI frameworks, and why they are needed.

Key Takeaways

What is Agentic AI?

Agentic AI refers to AI systems that can think, plan, and act beyond a single response. They function as independent digital collaborators, proficient in executing multi-step activities, interfacing with external apps, and adjusting to new contexts.

Agentic AI typically combines

• LLMs (like GPT, Claude, or LLaMA) for reasoning and natural language generation.
• Tools and APIs that allow access to databases, CRMs, and applications.
• Memory systems that store and recall context across long-running tasks.
• Orchestration layers that let you plan, work together, and manage workflows.

If a chatbot is like a student answering questions, an agentic AI system is like a project manager. It collects information, checks it, and gives results.
