a smol course

This is a practical course on aligning language models for your specific use case. It's a handy way to get started with aligning language models, because everything runs on most local machines. There are minimal GPU requirements and no paid services. The course is built around the SmolLM3 and SmolVLM2 models, but the skills you'll learn can be applied to larger models or other small LLMs/VLMs as well.

Why Small Language Models?

While large language models have shown impressive capabilities, they often require significant computational resources and can be overkill for focused applications. Small language models offer several advantages for domain-specific applications:

• Efficiency: Require significantly less computational resources to train and deploy
• Customization: Easier to fine-tune and adapt to specific domains
• Control: Better understanding and control of model behavior
• Cost: Lower operational costs for training and inference
• Privacy: Can be run locally without sending data to external APIs
• Green Technology: Advocates efficient usage of resources with reduced carbon footprint
• Easier Academic Research Development: Provides an easy starter for academic research with cutting-edge LLMs with less logistical constraints

Prerequisites

Before starting, ensure you have the following:

• Basic understanding of machine learning and natural language processing.
• Familiarity with Python, PyTorch, and the transformers library.
• Access to a pre-trained language model and a labeled dataset.
