 In this section, we've explored the three main Transformer architectures and some specialized attention mechanisms. Understanding these architectural differences is crucial for selecting the right model for your specific NLP task.
 
-As we move forward in the course, you'll get hands-on experience with these different architectures and learn how to fine-tune them for your specific needs. In the next section, we'll look at some of the limitations and biases present in these models that you should be aware of when deploying them.
