Phi-4: Key Features and Capabilities

Phi-4 is a cutting-edge language model boasting 14 billion parameters. Its architecture is optimized for memory and computational efficiency, making it suitable for developers with limited resources. The model uses a decoder-only transformer architecture and a 16K token context window (expanded from 4K during mid-training), enabling extensive conversations and detailed text generation. Training involved a massive dataset (approximately 10 trillion tokens) comprising diverse sources. Safety features, including supervised fine-tuning and preference optimization, are integrated to ensure responsible use.

Prerequisites

Before you begin, ensure you have the following:

• A Hugging Face account.
• Python 3.7 or higher installed.
• The transformers, torch, and huggingface_hub libraries. Install them using:

pip install transformers torch huggingface_hub
