This tutorial provides a comprehensive coding walkthrough for building an advanced AI pipeline using Microsoft's Phi-4-mini language model. The guide demonstrates how to leverage this compact model for high-performance tasks within resource-constrained environments like Google Colab.
Key topics covered include:
- Setting up 4-bit quantized inference to optimize GPU memory usage.
- Implementing streaming chat and multi-step chain-of-thought reasoning.
- Executing native tool calling and function calling for agentic interactions.
- Building a retrieval-augmented generation (RAG) pipeline using FAISS and sentence transformers.
- Performing lightweight LoRA fine-tuning to inject new knowledge into the model.
