# Implementing Load Balancing Logic in a Flask Chatbot

![](https://clemenssiebler.com/images/fallback_larger_model.png)

In this post, we will dive deep into the load balancing logic implemented in a Flask-based chatbot that utilizes Azure OpenAI's models. Load balancing is crucial for ensuring that our application can handle varying loads effectively and maintain high availability by seamlessly switching between different models based on their performance and availability.

## Understanding Load Balancing in Chatbots

Load balancing in the context of a chatbot refers to the strategy of distributing user requests across multiple models or instances. This approach helps:

1. **Avoid Rate Limits**: Different models may have different rate limits and capabilities. By distributing requests among them, we can minimize the chances of hitting these limits.

2. **Enhance Availability**: If one model is experiencing issues or is unavailable, the system can automatically switch to another model, ensuring that the chatbot remains operational.

3. **Optimize Performance**: Different models may perform better for specific queries. Load balancing allows us to utilize the strengths of each model effectively.
