Failover

Automatic backup when things fail

Agents can failover to backup models when the primary fails.

Quick Start

1. Simple Usage

   import { Agent } from 'praisonai';
   
   const agent = new Agent({
     llm: 'gpt-4o',
     fallback: ['gpt-4-turbo', 'gpt-3.5-turbo']
   });
   
   await agent.chat('Hello');
   // Uses gpt-4o, falls back if unavailable

2. With Configuration

   const agent = new Agent({
     llm: 'gpt-4o',
     fallback: [
       'anthropic/claude-3',
       'google/gemini-pro'
     ]
   });

User Interaction Flow

Configuration Levels

// Level 1: Array - Simple fallback list
const agent = new Agent({
  llm: 'gpt-4o',
  fallback: ['gpt-4-turbo', 'gpt-3.5-turbo']
});

// Level 2: Dict - With options
const agent = new Agent({
  llm: 'gpt-4o',
  fallback: {
    models: ['gpt-4-turbo', 'gpt-3.5-turbo'],
    retries: 2
  }
});

// Level 3: Instance - Full control
const agent = new Agent({
  failover: {
    primary: 'gpt-4o',
    fallbacks: ['gpt-4-turbo', 'claude-3'],
    strategy: 'round-robin',  // or 'priority'
    healthCheck: true
  }
});
