开源模型应用落地-qwen模型小试-调用qwen1.5新模型-进阶篇（六）_qwen2

一、前言

    经过前五篇“qwen模型小试”文章的学习，我们已经熟练掌握qwen大模型的使用。然而，就在前几天开源社区又发布了qwen1.5版本，它是qwen2模型的测试版本。在基于transformers的使用方式上有较大的调整，现在，我们赶紧跟上脚步，去体验一下新版本模型的推理质量。

二、术语

2.1. Qwen1.5

    Qwen1.5 is the beta version of Qwen2, a transformer-based decoder-only language model pretrained on a large amount of data. In comparison with the previous released Qwen, the improvements include:

• 6 model sizes, including 0.5B, 1.8B, 4B, 7B, 14B, and 72B;
• Significant performance improvement in human preference for chat models;
• Multilingual support of both base and chat models;
• Stable support of 32K context length for models of all sizes
• No need of trust_remote_code.
