Welcome to the exciting world of Qwen 1.5-1.8B Chat GGUF! This guide will walk you through everything you need to know about using this transformer-based decoder-only language model effectively.

Introduction

The Qwen 1.5 model is a beta version of Qwen 2. It boasts significant enhancements, including:

• 8 model sizes ranging from 0.5B to 72B.
• Enhanced performance in human preference for chat models.
• Multilingual support across all models.
• Stable support for 32K context lengths.
• Elimination of the need for trust_remote_code.

For detailed explanations on performance and architecture improvements, please see our blog post and the GitHub repo.

Understanding the Model

The Qwen 1.5 model showcases various sizes tailored for different requirements. Think of each model size like different sizes of tools in a toolbox. You have small tools that are perfect for delicate tasks and larger tools that can tackle robust jobs. In this scenario, the model sizes range from tiny (0.5B) to colossal (72B). Each serves its purpose based on the complexity and context of the task at hand.

Training Details

Qwen 1.5 has been pretrained using a vast amount of data and refined through supervised fine-tuning and direct preference optimization. This is like a chef masterfully preparing a dish after getting feedback from numerous taste testers – it ensures the final product is both delicious and satisfying for different palates.

Getting Started with Qwen 1.5

Follow these steps to get started with Qwen 1.5:

Requirements

Before diving in, ensure you clone llama.cpp and follow the installation guide provided there.

How to Use the Model

Cloning the repository may not be the most efficient method to download models. Instead, you can manually download the required GGUF file or use the huggingface-cli. Here’s how to do it:

huggingface-cli download QwenQwen1.5-1.8B-Chat-GGUF qwen1_5-1_8b-chat-q8_0.gguf --local-dir . --local-dir-use-symlinks False

Once you have downloaded the necessary files, you can run Qwen 1.5 using llama.cpp with the command below:

./main -m qwen1_5-1_8b-chat-q8_0.gguf -n 512 --color -i -cml -f prompts/chat-with-qwen.txt

Troubleshooting

If you encounter issues during installation or while running the model, here are some troubleshooting steps:

• Ensure you have the latest version of the huggingface-cli installed.
• Check your internet connection if downloads are failing.
• Look for error messages in the terminal, as they can provide clues for resolution.
• If a specific model file is not running, try redownloading the GGUF file.
