Building Reliable AI Systems with Smart Routing

Reliability is critical for production AI systems. TarqaAI's smart routing capabilities automatically handle failures, optimize latency, and balance load across providers.

What is Smart Routing?

Smart routing goes beyond simple load balancing. It intelligently selects the best model for each request based on:

Model Selection in Practice

Route each request to the right model for the task by simply changing the model field. Because TarqaAI exposes all models through one OpenAI-compatible endpoint, you can implement routing logic entirely in your application:

javascript
import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.TARQA_API_KEY,
  baseURL: 'https://tarqaai.com/v1',
});

async function routeRequest(userMessage: string, messageHistory: any[]) {
  // Route to a capable reasoning model for complex queries
  const isComplex = messageHistory.length > 8 || userMessage.length > 500;
  const model = isComplex ? 'claude-opus-4-6' : 'gemini-2.5-flash';

  const response = await client.chat.completions.create({
    model,
    messages: [...messageHistory, { role: 'user', content: userMessage }],
  });

  return response.choices[0].message.content;
}

Provider Availability

TarqaAI routes each request to the specified model through its provider. If a provider experiences degraded availability, you can switch models by updating the model field in your application — no infrastructure changes required:

javascript
// Failover example: try primary model, fall back on error
async function reliableCompletion(messages: any[]) {
  const models = ['gpt-4.1', 'claude-sonnet-4-5', 'gemini-2.5-pro'];

  for (const model of models) {
    try {
      const response = await client.chat.completions.create({ model, messages });
      return response.choices[0].message.content;
    } catch (err: any) {
      if (err.status === 503 && model !== models[models.length - 1]) continue;
      throw err;
    }
  }
}
