| 7 | +# Agent Architecture |
| 8 | + |
| 9 | +Understanding how AI agents are structured will help you build more effective agents. This lesson covers the fundamental components of an agent's architecture. |
| 10 | + |
| 11 | +## Basic Components of an AI Agent |
| 12 | + |
| 13 | +Every AI agent, regardless of complexity, has these basic components: |
| 14 | + |
| 15 | +```mermaid |
| 16 | +graph TD |
| 17 | + A[Sensors/Input] --> B[Processing Unit] |
| 18 | + B --> C[Decision-Making] |
| 19 | + C --> D[Actions/Output] |
| 20 | +``` |
| 21 | + |
| 22 | +### 1. Input (Sensors) |
| 23 | + |
| 24 | +This is how agents receive information from their environment. |
| 25 | + |
| 26 | +<CardGroup cols={1}> |
| 27 | + <Card title="Examples of Input" icon="eye"> |
| 28 | + - Text input from users |
| 29 | + - Data from databases |
| 30 | + - Image or audio input |
| 31 | + - API responses |
| 32 | + - Sensor readings (in physical agents) |
| 33 | + </Card> |
| 34 | +</CardGroup> |
| 35 | + |
| 36 | +### 2. Processing Unit |
| 37 | + |
| 38 | +This component processes information and converts it into a format the agent can understand. |
| 39 | + |
| 40 | +<CardGroup cols={1}> |
| 41 | + <Card title="Processing Functions" icon="gears"> |
| 42 | + - Data cleaning and transformation |
| 43 | + - Feature extraction |
| 44 | + - Context building |
| 45 | + - Information retrieval |
| 46 | + - Pattern recognition |
| 47 | + </Card> |
| 48 | +</CardGroup> |
| 49 | + |
| 50 | +### 3. Decision-Making Core |
| 51 | + |
| 52 | +The "brain" of the agent that determines what actions to take. |
| 53 | + |
| 54 | +<CardGroup cols={1}> |
| 55 | + <Card title="Decision Components" icon="brain"> |
| 56 | + - Language models (like GPT-4) |
| 57 | + - Rule systems |
| 58 | + - Planning algorithms |
| 59 | + - Knowledge base |
| 60 | + - Memory systems |
| 61 | + </Card> |
| 62 | +</CardGroup> |
| 63 | + |
| 64 | +### 4. Output (Actions) |
| 65 | + |
| 66 | +The actions the agent can perform to achieve its goals. |
| 67 | + |
| 68 | +<CardGroup cols={1}> |
| 69 | + <Card title="Action Examples" icon="hand"> |
| 70 | + - Generating text responses |
| 71 | + - Creating visual content |
| 72 | + - Making API calls |
| 73 | + - Controlling other systems |
| 74 | + - Updating databases |
| 75 | + </Card> |
| 76 | +</CardGroup> |
| 77 | + |
| 78 | +## The Agent Loop |
| 79 | + |
| 80 | +Agents operate in a continuous loop: |
| 81 | + |
| 82 | +```mermaid |
| 83 | +graph LR |
| 84 | + A[Perceive] --> B[Process] |
| 85 | + B --> C[Decide] |
| 86 | + C --> D[Act] |
| 87 | + D --> A |
| 88 | +``` |
| 89 | + |
| 90 | +This cycle allows agents to continuously: |
| 91 | +1. Gather information |
| 92 | +2. Update their understanding |
| 93 | +3. Make new decisions |
| 94 | +4. Take appropriate actions |
| 95 | + |
| 96 | +## PraisonAI Agent Architecture |
| 97 | + |
| 98 | +In the PraisonAI framework, agents follow a specific architecture: |
| 99 | + |
| 100 | +<CardGroup cols={1}> |
| 101 | + <Card title="PraisonAI Agent Components" icon="puzzle-piece"> |
| 102 | + - **Instructions**: Defines the agent's purpose and behavior |
| 103 | + - **Language Model**: Powers the agent's intelligence (e.g., GPT-4) |
| 104 | + - **Memory**: Stores context and previous interactions |
| 105 | + - **Tools**: Specialized capabilities an agent can use |
| 106 | + </Card> |
| 107 | +</CardGroup> |
| 108 | + |
| 109 | +### Simple Agent Structure |
| 110 | + |
| 111 | +```python |
| 112 | +from praisonaiagents import Agent |
| 113 | + |
| 114 | +# Create a simple agent |
| 115 | +research_agent = Agent( |
| 116 | + instructions="Research the latest developments in renewable energy", |
| 117 | + name="ResearchAgent" |
| 118 | +) |
| 119 | + |
| 120 | +# Start the agent |
| 121 | +research_agent.start() |
| 122 | +``` |
| 123 | + |
| 124 | +## Understanding Agent Communication |
| 125 | + |
| 126 | +Multi-agent systems allow agents to communicate with each other: |
| 127 | + |
| 128 | +```mermaid |
| 129 | +graph LR |
| 130 | + A[Agent 1] --> B[Agent 2] |
| 131 | + B --> C[Agent 3] |
| 132 | + C --> A |
| 133 | +``` |
| 134 | + |
| 135 | +Each agent can: |
| 136 | +- Pass information to other agents |
| 137 | +- Request assistance from specialized agents |
| 138 | +- Collaborate on complex tasks |
| 139 | + |
