Smart Model Routing

Never let a single point of failure kill your AI workflow AnyAPI’s routing system ensures your applications stay resilient, fast, and cost-effective by intelligently managing model selection and fallbacks. Choose your strategy: let our AI pick the perfect model, or build bulletproof fallback chains.

​
🎯 Auto Router

The smart choice that thinks for you Point your requests at anyapi/auto and watch as our AI-powered routing system automatically selects the optimal model for each prompt. No more guessing, no more manual optimization—just results. 
{
  "model": "anyapi/auto",
  "messages": [
    {
      "role": "user", 
      "content": "Explain quantum computing to a 10-year-old"
    }
  ]
}
What happens behind the scenes:
  • NotDiamond AI analyzes your prompt’s complexity, style, and requirements
  • Dynamically routes to the best-performing model for that specific task
  • Returns the response with the actual model used in the model field
Perfect for: Applications that need consistent quality without micromanagement

​
🛡️ Fallback Chains

Because reliability isn’t optional Build unbreakable AI pipelines with the models parameter. Define your preferred model hierarchy and let AnyAPI handle the rest when things go sideways. 
{
  "models": [
    "anthropic/claude-3.5-sonnet",    // First choice
    "openai/gpt-4o",                  // Solid backup
    "gryphe/mythomax-l2-13b"          // Always-available fallback
  ],
  "messages": [
    {
      "role": "user",
      "content": "Generate a product description for wireless headphones"
    }
  ]
}
Your safety net activates when:
  • 🚫 Primary model hits rate limits
  • ⏰ Provider experiences downtime
  • 🛑 Content gets flagged by moderation
  • 📏 Context length exceeds limits
  • 💥 Any other model-specific errors
The magic: You only pay for the model that actually processes your request. No extra charges for the intelligent routing.

​
🔧 OpenAI SDK Integration

Plug and play with your existing code Already using the OpenAI SDK? No problem. AnyAPI’s routing works seamlessly with your current setup: 
import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://api.anyapi.ai/api/v1',
  apiKey: 'your-anyapi-key'
});

const completion = await client.chat.completions.create({
  model: 'openai/gpt-4o',
  models: [
    'anthropic/claude-3.5-sonnet', 
    'meta-llama/llama-3.1-70b-instruct'
  ],
  messages: [{
    role: 'user',
    content: 'Write a haiku about debugging code at 3 AM'
  }]
});

console.log(completion.choices[0].message.content);

💡 Pro Tips

Mix and match strategies: Use Auto Router for general tasks and fallback chains for mission-critical workflows. Strategic ordering: Place your preferred models first in the array—AnyAPI tries them in sequence. Cost optimization: Mix premium and budget models to balance quality and spend. Monitor model usage: Check the returned model field to track which models are actually handling your requests.
