Qwen2.5-0.5B-Instruct-GGUF (Q4_K_M)

Optimized by Modelfix.com

This repository provides a high-efficiency GGUF quantization of Alibaba's Qwen2.5-0.5B-Instruct. This 0.5B model punches significantly above its weight in coding and mathematics.

📊 Quantization Benchmarks

Our validation process for this Q4_K_M build yielded the following metrics:

Perplexity (PPL): 9.249 🙂
KL Divergence: 0.025 🤩
FLIP Score: 7.8% 🙂

⚙️ Implementation Details

Format: GGUF (Quantized to Q4_K_M)
Architecture: Transformer-based decoder with RoPE, SwiGLU, RMSNorm, Attention QKV bias, and Tied Word Embeddings.
Parameters: 494 Million (0.49B)
Context Window: Native 32,768 tokens (Supports generation up to 8,192 tokens).
Attention: Grouped Query Attention (GQA) with 14 Query heads and 2 KV heads.
Multilingual: Supports over 29+ languages (English, Chinese, French, Spanish, etc.).
Strengths: Logic, reasoning, and instruction following in a compact size.
Ideal Use Case: Edge devices, mobile applications, and high-speed basic automation.

📊 Hardware Requirements & Performance

Quantization	File Size	Recommended VRAM	Recommended Device
Q8_0	~531 MB	1.2 GB	Desktop / Server
