    "# Fine-Tuning Qwen-Chat Large Language Model (Multiple GPUs)\n",
    "\n",
    "Tongyi Qianwen is a large language model developed by Alibaba Cloud based on the Transformer architecture, trained on an extensive set of pre-training data. The pre-training data is diverse and covers a wide range, including a large amount of internet text, specialized books, code, etc. In addition, an AI assistant called Qwen-Chat has been created based on the pre-trained model using alignment mechanism.\n",
    "\n",
    "This notebook uses Qwen-1.8B-Chat as an example to introduce how to fine-tune the Qianwen model using Deepspeed.\n",
