+## 🔒 Best Practices Implemented
+
+- **Rate Limiting**: To prevent abuse and ensure fair usage, rate limiting is implemented with **exponential backoff**. If the user exceeds the allowed number of requests, they will be temporarily blocked from making more requests.
+- **Caching**: Redis is used to cache frequent queries, reducing the load on the AI models and improving the response times.
+- **Input Validation**: We validate all incoming requests using **Zod** to ensure the data is structured and safe.
+- **Streaming**: For long-running processes, such as AI completions, we stream the responses in real-time.
+- **Monitoring**: The API tracks usage metrics and errors via **Prometheus**, allowing you to monitor the health and performance of your system in real-time.

--->
+- The **Rate Limiting** feature uses Redis for storing request counts, ensuring that users cannot flood the system with requests.
+- **Caching** stores frequently requested data in Redis, which minimizes the number of redundant calls to the AI models, improving efficiency and speed.
+- **Zod** ensures that all user inputs are validated before they are processed, making the application more secure and reliable.
+- **Streaming** allows for real-time responses, reducing the wait time for users interacting with models that take longer to process.
+- **Prometheus** provides valuable insights into the health of the API, making it easier to monitor usage, errors, and response times.
