Qwen2.5-1.5B-Instruct-GGUF

Introduction

Qwen2.5 is the latest series of Qwen large language models. For Qwen2.5, we release a number of base language models and instruction-tuned language models ranging from 0.5 to 72 billion parameters. Qwen2.5 brings the following improvements upon Qwen2:

Significantly more knowledge and has greatly improved capabilities in coding and mathematics, thanks to our specialized expert models in these domains.

Significant improvements in instruction following, generating long texts (over 8K tokens), understanding structured data (e.g, tables), and generating structured outputs especially JSON. More resilient to the diversity of system prompts, enhancing role-play implementation and condition-setting for chatbots.

Long-context Support up to 128K tokens and can generate up to 8K tokens.

Multilingual support for over 29 languages, including Chinese, English, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Vietnamese, Thai, Arabic, and more.

This repo contains the instruction-tuned 1.5B Qwen2.5 model in the GGUF Format, which has the following features:

Type: Causal Language Models

Training Stage: Pretraining & Post-training

Architecture: transformers with RoPE, SwiGLU, RMSNorm, Attention QKV bias and tied word embeddings

Number of Parameters: 1.54B

Number of Paramaters (Non-Embedding): 1.31B

Number of Layers: 28

Number of Attention Heads (GQA): 12 for Q and 2 for KV

Context Length: Full 32,768 tokens and generation 8192 tokens

Quantization: q2_K, q3_K_M, q4_0, q4_K_M, q5_0, q5_K_M, q6_K, q8_0

For more details, please refer to our blog, GitHub, and Documentation.

Quickstart

Check out our llama.cpp documentation for more usage guide.

We advise you to clone llama.cpp and install it following the official guide. We follow the latest version of llama.cpp. In the following demonstration, we assume that you are running commands under the repository llama.cpp.

Since cloning the entire repo may be inefficient, you can manually download the GGUF file that you need or use huggingface-cli: 1. Install

shell
   pip install -U huggingface_hub

2. Download:

shell
   huggingface-cli download Qwen/Qwen2.5-1.5B-Instruct-GGUF qwen2.5-1.5b-instruct-q5_k_m.gguf --local-dir . --local-dir-use-symlinks False

For users, to achieve chatbot-like experience, it is recommended to commence in the conversation mode:

shell
./llama-cli -m  \
    -co -cnv -p "You are Qwen, created by Alibaba Cloud. You are a helpful assistant." \
    -fa -ngl 80 -n 512

Evaluation & Performance

Detailed evaluation results are reported in this 📑 blog.

For quantized models, the benchmark results against the original bfloat16 models can be found here
