The Difference Between AI Agents and Large Models

The Foundational Architecture of AI Agents

1. Planning: Equivalent to the Agent's "thinking mode," implemented through LLM prompt engineering, helping the Agent reasonably break down tasks, evaluate tools, and reflect on the execution process.

2. Memory: Divided into short-term and long-term memory. Short-term memory is cleared after a single session ends, while long-term memory stores user information and uses vector databases to support retrieval.

3. Tools: Agents perceive the environment by calling APIs, plugins, and other tools to obtain external information needed for tasks.

4. Action: Execute actions based on planning and memory, interact with the external environment, and complete tasks such as AI robot operations.

The Difference Between RAG and LLM

• LLM: Such as ChatGPT and Wenxin Yiyan, trained on large amounts of text data, excels at text generation and understanding, but has limited knowledge and slow update speed.

• RAG: Retrieval-Augmented Generation (RAG) expands the knowledge scope of LLMs by introducing external data, improving accuracy in query and generation tasks. It combines the generative capabilities of LLMs with external retrieval, enhancing response timeliness and information completeness.

Future Applications and Technologies of AI Agents

1. Smart Home: Agent-based home control systems can understand complex commands and automatically complete multi-step tasks.

2. Automated Customer Service: Through multi-turn dialogue and memory management, Agents can provide continuous, personalized support to users.

3. Medical Assistance: In medical diagnosis and health advice, Agents will leverage RAG and LLMs to generate accurate, personalized feedback.
