Xwen-7B-Chat: Top-Performing Open-Source Chat Model
Xwen-7B-Chat, developed by xwen-team, is a 7.6 billion parameter large language model post-trained from the Qwen2.5-7B base model. It is specifically designed and optimized for chat performance, demonstrating leading capabilities among open-sourced models under 10 billion parameters.
Key Capabilities & Performance
- Top-1 Chat Performance: Achieves the highest scores among open-source models below 10B parameters on widely-used benchmarks such as Arena-Hard-Auto, AlignBench, and MT-Bench (as of February 1, 2025).
- Strong Benchmark Results:
- Arena-Hard-Auto (No Style Control): Scored 59.4, outperforming Qwen2.5-7B-Instruct (50.4) and Gemma-2-27B-IT (57.5).
- Arena-Hard-Auto (Style Control): Scored 50.3, surpassing Qwen2.5-7B-Instruct (46.9) and Gemma-2-27B-IT (47.5).
- AlignBench-v1.1: Achieved a score of 6.88, higher than Qwen2.5-7B-Chat (6.56).
- MT-Bench: Scored 7.98, exceeding Qwen2.5-7B-Chat (7.71).
- High Context Length: Supports a context length of 131072 tokens, enabling extensive conversational interactions.
- Qwen2.5 Compatibility: Utilizes the same tokenizer and chat template as Qwen2.5-Instruct models, ensuring ease of integration.
When to Use Xwen-7B-Chat
