Routing Strategies

The SmartRouter supports 4 strategies. Set one when calling enableRouter().

cheapest​

Routes to the provider with the lowest costPerToken.

dex.enableRouter({
  strategy: 'cheapest',
  costPerToken: {
    openai: 0.005,
    anthropic: 0.003,
    google: 0.0005,
  },
})

fastest​

Routes to the provider with the best average latency based on live stats.

dex.enableRouter({ strategy: 'fastest' })

round-robin​

Distributes requests evenly across all healthy providers.

dex.enableRouter({ strategy: 'round-robin' })

fallback-chain​

Uses your preferred order. If one fails, instantly tries the next.

dex.enableRouter({
  strategy: 'fallback-chain',
  fallbackOrder: ['anthropic', 'openai', 'google'],
})

Switching at runtime​

dex.getRouter().strategy = 'fastest'
