In this guide, we will explore the process of working with Llamacpp imatrix quantizations of the Tess-3-Llama-3.1-70B model. By the end, you’ll be able to download high-quality quantized models suited for your computing resources.

Understanding the Basics

Imagine you’re packing a suitcase for a trip. You have different sizes of clothing depending on how long you plan to stay and what the weather will be like. Similarly, when you quantize models like Tess-3-Llama-3.1-70B, you’re compressing the model to make it fit better within your system’s memory limitations while attempting to maintain optimal performance.

1. Getting Started with Quantization

To start with the quantization process, you’ll need to utilize the llama.cpp library. Specifically, you will be using the release b3509.

2. Download the Original Model

The original model can be obtained from here. You’ll then proceed to perform the quantization using the imatrix options with the dataset found here.

3. Understanding the Prompt Format

To successfully interact with the model, you’ll need to structure your prompts correctly. The format is as follows:

<|begin_of_text|><|start_header_id|>system<|end_header_id|>{system_prompt}<|eot_id|><|start_header_id|>user<|end_header_id|>{prompt}<|eot_id|><|start_header_id|>assistant<|end_header_id|>

4. Options for Downloading Quantized Models

Below are the quantized files you can choose from:

• Tess-3-Llama-3.1-70B-Q8_0.gguf | Size: 74.98GB | Description: Extremely high quality, generally unneeded but max available quant.
• Tess-3-Llama-3.1-70B-Q6_K.gguf | Size: 57.89GB | Description: Very high quality, near perfect, *recommended*.
• Tess-3-Llama-3.1-70B-Q5_K_M.gguf | Size: 49.95GB | Description: High quality, *recommended*.
• Tess-3-Llama-3.1-70B-Q2_K.gguf | Size: 26.38GB | Very low quality but surprisingly usable.

5. Downloading via huggingface-cli

First, ensure that you have the huggingface-cli installed:

pip install -U "huggingface_hub[cli]"

To target a specific file for download:

huggingface-cli download bartowski/Tess-3-Llama-3.1-70B-GGUF --include "Tess-3-Llama-3.1-70B-Q4_K_M.gguf" --local-dir ./

If the model exceeds 50GB, it will have been split into multiple files. Run this command to download them all:

huggingface-cli download bartowski/Tess-3-Llama-3.1-70B-GGUF --include "Tess-3-Llama-3.1-70B-Q8_0/*" --local-dir ./

Troubleshooting Tips

• If you encounter issues during the quantization or download process, ensure your internet connection is stable.
• Adjust the local directory permissions if you have trouble accessing or saving files.
• For optimal performance, monitor your system’s RAM and VRAM and choose quant sizes accordingly.
