+//! Qwen2 model implementation with quantization support.
+//!
+//! Qwen2 is a large language model from Alibaba optimized for efficiency.
+//! This implementation provides quantization for reduced memory and compute.
+//!
+//! Key characteristics:
+//! - Streaming decode support
+//! - Grouped query attention (GQA)
+//! - RMSNorm for layer normalization
+//! - Rotary positional embeddings (RoPE)
+//! - Support for 8-bit quantization
+//!
+//! References:
