Comparative Analysis of Qwen2.5 and Llama-3.1-8B on Synthetic Context Retrieval Benchmarks

In this work, we present Qwen3, the latest version of the Qwen model family. Qwen3 comprises a series of large language models (LLMs) designed to advance performance, efficiency, and multilingual capabilities. The Qwen3 series includes models of both dense and Mixture-of-Expert (MoE) architectures, with parameter scales ranging from 0.6 to 235 billion. A key innovation in Qwen3 is the integration of thinking mode (for complex, multi-step reasoning) and non-thinking mode (for rapid, context-driven responses) into a unified framework. This eliminates the need to switch between different models--

Research goal: How does Qwen2.5's performance on synthetic context retrieval tasks (e.g., Ruler) compare to other 8B-parameter models like Llama-3.1-8B when using identical benchmark configurations?
