4. Quick Start Guide
To swiftly set up and begin using the Yi-1.5 models, refer to the official README. This document guides you through the steps needed to run the models effectively.
5. Understanding the Code: An Analogy
Imagine the Yi-1.5 as a chef in a high-end restaurant. The ingredients (tokens) represent the vast corpus of data it has been trained on. The cooking (pre-training) process is how the chef learns to make exquisite dishes (model outputs). As the chef fine-tunes their skills with feedback from food critics (fine-tuning samples), they get better at preparing a wider variety of meals (improving capabilities in multiple tasks). Just like any seasoned chef goes through practice and learning, Yi-1.5 refines its ability through extensive training on various tasks, making it not only efficient but also versatile.
