Quantization Description

This model is quantized using selective quantization from the Qwen2.5-Coder-0.5B base model to increase its speed while preserving the capabilities in generating relevant and accurate responses related python programming. The quantization method included 32-bit quantization of the following Layers:

• q_proj
• k_proj
• v_proj
• o_proj
• lm_head

Rest of the remaining layers were quantized to q3_k_l

Model Description

Layer Name	Role (Short)	Type
q_proj, k_proj, v_proj	Compute query, key, and value for attention mechanism	Attention Proj
o_proj	Projects attention output back to model hidden size	Attention Proj
down_proj	Projects MLP output down to hidden size	MLP
gate_proj	First part of Gated MLP, controls info flow	MLP
up_proj	Expands hidden size in MLP	MLP
lm_head	Final linear layer for logits	Output Head
embed_tokens	Token embedding layer	Input Embed
norm	Final layernorm	Normalization
*_layernorm	Normalize inputs to layers	Normalization
