Pros
An AI engineer is a specialized software engineer who builds, deploys, and maintains artificial intelligence models in production environments. They bridge the gap between data science research and functional applications. While a data scientist might build a model in a controlled lab setting to prove a concept, an AI engineer takes that model and ensures it can handle thousands of users, run efficiently in real-time, and integrate seamlessly into a company's main product (like a recommendation engine on Netflix or a fraud detection system at a bank).
Cons
Neural Networks (CNNs for images, RNNs/Transformers for text). Frameworks: Choose one major framework to master deeply: PyTorch (preferred in research and increasingly in production) or TensorFlow/Keras.
