15
-
16
- ## Introduction
17
-
18
- Qwen2.5 is the latest series of Qwen large language models. For Qwen2.5, we release a number of base language models and instruction-tuned language models ranging from 0.5 to 72 billion parameters. Qwen2.5 brings the following improvements upon Qwen2:
19
-
20
- - Significantly **more knowledge** and has greatly improved capabilities in **coding** and **mathematics**, thanks to our specialized expert models in these domains.
21
- - Significant improvements in **instruction following**, **generating long texts** (over 8K tokens), **understanding structured data** (e.g, tables), and **generating structured outputs** especially JSON. **More resilient to the diversity of system prompts**, enhancing role-play implementation and condition-setting for chatbots.
22
- - **Long-context Support** up to 128K tokens and can generate up to 8K tokens.
23
- - **Multilingual support** for over 29 languages, including Chinese, English, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Vietnamese, Thai, Arabic, and more.
24
-
25
- **This repo contains the instruction-tuned 72B Qwen2.5 model**, which has the following features:
26
- - Type: Causal Language Models
27
- - Training Stage: Pretraining & Post-training
28
- - Architecture: transformers with RoPE, SwiGLU, RMSNorm, and Attention QKV bias
29
- - Number of Parameters: 72.7B
30
- - Number of Paramaters (Non-Embedding): 70.0B
31
- - Number of Layers: 80
32
- - Number of Attention Heads (GQA): 64 for Q and 8 for KV
33
- - Context Length: Full 131,072 tokens and generation 8192 tokens
34
- - Please refer to [this section](#processing-long-texts) for detailed instructions on how to deploy Qwen2.5 for handling long texts.
35

36
- For more details, please refer to our [blog](https://qwenlm.github.io/blog/qwen2.5/), [GitHub](https://github.com/QwenLM/Qwen2.5), and [Documentation](https://qwen.readthedocs.io/en/latest/).
37
-
38
- ## Requirements
39
-
40
- The code of Qwen2.5 has been in the latest Hugging face `transformers` and we advise you to use the latest version of `transformers`.
41
-
42
- With `transformers<4.37.0`, you will encounter the following error:
43
- ```
44
- KeyError: 'qwen2'
45
- ```
46
-
47
- ## Quickstart
48
-
49
- Here provides a code snippet with `apply_chat_template` to show you how to load the tokenizer and model and how to generate contents.
50
-
51
- ```python
52
- from transformers import AutoModelForCausalLM, AutoTokenizer
53
-
54
- model_name = "Qwen/Qwen2.5-72B-Instruct"
55
-
56
- model = AutoModelForCausalLM.from_pretrained(
57
- model_name,
58
- torch_dtype="auto",
59
- device_map="auto"
60
- )
61
- tokenizer = AutoTokenizer.from_pretrained(model_name)
62
-
63
- prompt = "Give me a short introduction to large language model."
64
- messages = [
65
- {"role": "system", "content": "You are Qwen, created by Alibaba Cloud. You are a helpful assistant."},
66
- {"role": "user", "content": prompt}
67
- ]
68
- text = tokenizer.apply_chat_template(
69
- messages,
70
- tokenize=False,
71
- add_generation_prompt=True
72
- )
73
- model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
74
-
75
- generated_ids = model.generate(
76
- **model_inputs,
77
- max_new_tokens=512
78
- )
79
- generated_ids = [
80
- output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
81
- ]
82
-
83
- response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
84
- ```
85
-
86
- ### Processing Long Texts
87
-
88
- The current `config.json` is set for context length up to 32,768 tokens.
89
- To handle extensive inputs exceeding 32,768 tokens, we utilize [YaRN](https://arxiv.org/abs/2309.00071), a technique for enhancing model length extrapolation, ensuring optimal performance on lengthy texts.
90
-
91
- For supported frameworks, you could add the following to `config.json` to enable YaRN:
92
- ```json
93
- {
94
- ...,
95
- "rope_scaling": {
96
- "factor": 4.0,
97
- "original_max_position_embeddings": 32768,
98
- "type": "yarn"
99
- }
100
- }
101
- ```
102
-
103
- For deployment, we recommend using vLLM.
104
- Please refer to our [Documentation](https://qwen.readthedocs.io/en/latest/deployment/vllm.html) for usage if you are not familar with vLLM.
105
- Presently, vLLM only supports static YARN, which means the scaling factor remains constant regardless of input length, **potentially impacting performance on shorter texts**.
106
- We advise adding the `rope_scaling` configuration only when processing long contexts is required.
107
-
108
- ## Evaluation & Performance
109
-
110
- Detailed evaluation results are reported in this [📑 blog](https://qwenlm.github.io/blog/qwen2.5/).
111
-
112
- For requirements on GPU memory and the respective throughput, see results [here](https://qwen.readthedocs.io/en/latest/benchmark/speed_benchmark.html).
