56
- ## :fountain_pen: 介绍
57
 
58
- MOSS是一个支持中英双语和多种插件的开源对话语言模型,`moss-moon`系列模型具有160亿参数,在FP16精度下可在单张A100/A800或两张3090显卡运行,在INT4/8精度下可在单张3090显卡运行。MOSS基座语言模型在约七千亿中英文以及代码单词上预训练得到,后续经过对话指令微��、插件增强学习和人类偏好训练具备多轮对话能力及使用多种插件的能力。
59
 
60
- **局限性**:由于模型参数量较小和自回归生成范式,MOSS仍然可能生成包含事实性错误的误导性回复或包含偏见/歧视的有害内容,请谨慎鉴别和使用MOSS生成的内容,请勿将MOSS生成的有害内容传播至互联网。若产生不良后果,由传播者自负。

332
-
333
- 在使用的时候注意 `moss-moon-003-base` 模型的 tokenizer 中,`eos token` 为 `<|endoftext|>`,在训练SFT模型时需要将该 token 指定为 `<eom>` token.

The model has seen 700B tokens during pre-training and consumed ~6.67x10<sup>22</sup> FLOPs in total.
37
+ - [**moss-moon-003-sft**](https://huggingface.co/fnlp/moss-moon-003-sft): We performed supervised fine-tuning on ~1.1M multi-turn conversational data. The fine-tuned model can follow instructions in multi-turn dialogues and refuse inappropriate requests.

45
+ - **moss-moon-003-plugin**: The final MOSS-003-plugin model trained using `moss-moon-003-pm`, which poccessed stronger abilities in understanding user intents and using plugins. Will be open-sourced in the near future.
46
 
47
+ ### Data
 
 
 
 
 
 
 
 
 
48
 
49
+ - [**moss-002-sft-data**](https://huggingface.co/datasets/fnlp/moss-002-sft-data): The multi-turn conversational data used to train MOSS-002, covering helpfulness, honesty, and harmlessness. The data is consisting of 570K English and 590K Chinese conversations generated by `text-davinci-003`.
50
+ - [**moss-003-sft-data**](https://github.com/OpenLMLab/MOSS/tree/main/SFT_data/conversations/conversation_without_plugins): The multi-turn conversational data used to train `moss-moon-003-sft`. The data is generated by `gpt-3.5-turbo` from a seed set of user prompts collected through our early deployed MOSS-002 API. In contrast to `moss-002-sft-data`, `moss-003-sft-data` is well-aligned with the real-world distribution of user intents, covering finer-grained categories and more diverse harmlessness-related data. The data consists of ~1.1M conversational data. Currently we open-sourced a small portion of it and will make public the full data in the near future.
51
+ - [**moss-003-sft-plugin-data**](https://github.com/OpenLMLab/MOSS/tree/main/SFT_data/conversations/conversation_with_plugins): The plugin-augmented multi-turn conversational data, which is consisting of ~300K conversations in which the AI assistant uses four plugins (search engine, text-to-image, calculator, and equation solver) to generate responses. Currently we open-sourced a small portion of data and will make public the full data in the near future.
52
+ - **moss-003-pm-data**: The preference data used to train `moss-moon-003-pm`, including ~180K additional dialogue contexts and their corresponding responses generated by `moss-moon-003-sft`. Will be publicly available in the near future.

54
+ ## :fountain_pen: Introduction
 
 
 
55
 
56
+ MOSS is an open-sourced plugin-augmented conversational language model. `moss-moon` models have 16B parameters, allowing users to perform inference on a single A100 GPU or 2 NVIDIA 3090 GPUs with FP16 precision, and on a single NVIDIA 3090 GPU with INT-4/8 precision. The base language model of MOSS was pre-trained on ~700B English, Chinese, and code tokens, including the PILE, BigQuery, BigPython, and our private Chinese corpus. The base model was then fine-tuned on multi-turn plugin-augmented conversational data. Finally, we performed preference-aware training to further improve the model.
57
 
58
+ **Limitations**: Due to the (relatively) small number of parameters and the autoregressive nature, MOSS is still possible to generate outputs that contain incorrect, misleading, or biased information. Please carefully check the contents generated by MOSS before you use them.

224
+ #### Model Quantization
225
 
226
+ Note: **Currently our quantized models do not support model parallism.**
227
 
228
+ In the case of limited GPU memory, you can use the quantized MOSS models to reduce memory and computation cost. We used [GPTQ](https://github.com/IST-DASLab/gptq) and OpenAI [triton](https://github.com/openai/triton) backend (only supports Linux) to implement quantized inference.
229
 
230
  ~~~python
231
  >>> from transformers import AutoTokenizer, AutoModelForCausalLM
232
  >>> tokenizer = AutoTokenizer.from_pretrained("fnlp/moss-moon-003-sft-int4", trust_remote_code=True)
233
  >>> model = AutoModelForCausalLM.from_pretrained("fnlp/moss-moon-003-sft-int4", trust_remote_code=True).half().cuda()
 
234
  >>> meta_instruction = "You are an AI assistant whose name is MOSS.\n- MOSS is a conversational language model that is developed by Fudan University.

235
  >>> plain_text = meta_instruction + "<|Human|>: Hello MOSS, can you write a piece of C++ code that prints out ‘hello, world’? <eoh>\n<|MOSS|>:"
236
  >>> inputs = tokenizer(plain_text, return_tensors="pt")
 
253
  This code uses the `std::cout` object to print the string "Hello, world!" to the console, and the `std::endl` object to add a newline character at the end of the output.

+ ## :fire: Fine-tuning MOSS
 
 
 
 
 
 
277
 
278
+ We also provided the Python code [finetune_moss.py](https://github.com/OpenLMLab/MOSS/blob/main/finetune_moss.py) for fine-tuning MOSS base model.
 
 
 
 
279
 
280
+ ### Requirements
 
 
 
 
281
 
282
  ```bash
283
  accelerate==0.17.1
 
288
  transformers==4.25.1
289
  ```
290
 
291
+ ### Start Training
292
+
293
+ Here we show an example of fine-tuning `moss-moon-003-base` on conversational data without plugins. It would be straightforward to fine-tune it on plugin-augmented data.
294
+
295
+ Step 1, prepare your data following the format in [conversation_without_plugins](https://github.com/OpenLMLab/MOSS/tree/main/SFT_data/conversations/conversation_without_plugins) and put it in the folder `sft_data`.
296
 
297
+ Step 2, download the [accelerate configs](https://github.com/OpenLMLab/MOSS/tree/main/configs) to your machine and modify it according to your compute configuration. Learn more on [accelerate documentation](https://huggingface.co/docs/accelerate/usage_guides/deepspeed).
298
 
299
+ Step 3, create `run.sh` and copy the following snippet:
300
 
301
  ```bash
302
  num_machines=4
 
321
  --save_step 2000"
322
  ```
323
 
324
+ Now you can start training:
325
+
326
  ```bash
327
  bash run.sh
328
  ```
 
 
 
 
 
329
 
330
+ Note: In the tokenizer of `moss-moon-003-base`, the eos token is `<|endoftext|>`, your need to specify it as `<eom>` when performing supervised fine-tuning.

339
+ ## :construction: Future Plans
340
 
341
+ We constantly improved the Chinese skills, honesty, harmlessness from MOSS-001 to MOSS-003, and enabled the model to use external plugins. However, MOSS-003 is still a very early version, and our journey has just begun. In the future, we will continue developing more advanced foundation models and open-sourcing more powerful MOSS.
342
 
343
+ - **Reasoning**: We are improving the reasoning abilities of MOSS by scaling up its base model and performing math-specific training.
344
+ - **Truthfulness & Safety**: We will reduce the hallucination of MOSS and improve its safety in the following versions.
345
+ - **Multi-modal**: Enabling the language model to see and to hear is a critical step towards general AI. We are working on integrating cross-modal abilities into MOSS.
346
+ - **Personalized**: Our expected MOSS should be personalized, it updates its knowledge during the interaction with users, and finally becomes an unique AI for each user.
