The helpful features of this AI model for Armando to answer questions include:

• Natural Language Understanding (NLU): The model can break down questions into meaningful components and identify the intent behind the question to understand what is being asked.
• Retrieval and Inference: It can search vast databases or knowledge bases to retrieve pertinent information related to the question topic.
• Natural Language Generation (NLG): The model forms coherent, contextually appropriate responses, mimicking human-like speech patterns.
• Deep Learning and Attention Mechanisms: Using advanced architectures like Transformers, the model comprehends semantic nuances and positions of answers in context, enabling accurate answer extraction.
• Unified and Efficient System: The model can quickly decide when to respond immediately and when to perform deeper reasoning for more complex inquiries.

These features combined enable the model to effectively analyze, understand, retrieve, and generate answers that help Armando address questions accurately.
