| 23 | + |
| 24 | +<AccordionGroup> |
| 25 | + <Accordion title="Single Agent Example" icon="user" defaultOpen> |
| 26 | + Create and run a single agent to perform a specific task: |
| 27 | + |
| 28 | + ```typescript |
| 29 | + import { Agent, PraisonAIAgents } from 'praisonai'; |
| 30 | + |
| 31 | + async function main() { |
| 32 | + // Create a simple agent (no task specified) |
| 33 | + const agent = new Agent({ |
| 34 | + name: "BiologyExpert", |
| 35 | + instructions: "Explain the process of photosynthesis in detail.", |
| 36 | + verbose: true |
| 37 | + }); |
| 38 | + |
| 39 | + // Run the agent |
| 40 | + const praisonAI = new PraisonAIAgents({ |
| 41 | + agents: [agent], |
| 42 | + tasks: ["Explain the process of photosynthesis in detail."], |
| 43 | + verbose: true |
| 44 | + }); |
| 45 | + |
| 46 | + try { |
| 47 | + console.log('Starting single agent example...'); |
| 48 | + const results = await praisonAI.start(); |
| 49 | + console.log('\nFinal Results:', results); |
| 50 | + } catch (error) { |
| 51 | + console.error('Error:', error); |
| 52 | + } |
| 53 | + } |
| 54 | + |
| 55 | + main(); |
| 56 | + ``` |
| 57 | + </Accordion> |
| 58 | + |
| 59 | + <Accordion title="Multi-Agent Example" icon="users" defaultOpen> |
| 60 | + Create and run multiple agents working together: |
| 61 | + |
| 62 | + ```typescript |
| 63 | + import { Agent, PraisonAIAgents } from 'praisonai'; |
| 64 | + |
| 65 | + async function main() { |
| 66 | + // Create multiple agents with different roles |

| 82 | + verbose: true |
| 83 | + }); |
| 84 | + |
| 85 | + // Run the agents in sequence |
| 86 | + const praisonAI = new PraisonAIAgents({ |
| 87 | + agents: [researchAgent, summaryAgent, recommendationAgent], |
| 88 | + tasks: [ |
| 89 | + "Research and analyze current renewable energy technologies and their implementation.", |
| 90 | + "Summarize the key findings from the research.", |
| 91 | + "Provide actionable recommendations based on the summary." |
