BatGPT-15B-sirius

介绍 (Introduction)

BatGPT-15B-sirius 是上海交通大学与武汉大学（或武汉大学与上海交通大学，排名不分先后）联合自然语言处理团队设计、预训练、对齐的系列大型语言模型 BatGPT 中的一个开源可商用版本。 BatGPT系列模型中还包括BatGPT-30B-orion，BatGPT-70B-alhena，以及BatGPT-140B-menkalinan。

BatGPT-15B-sirius 包含 150 亿参数，在中英文 1T 语料上进行了预训练，在权威的中文和英文 benchmark 上均取得同不错的效果。BatGPT-15B-sirius 有如下几个特点：

1. 支持长达32K的上下文：BatGPT-15B-sirius 采用旋转位置编码RoPE，在预训练阶段采用 2048 序列长度，并且在指令微调阶段逐步扩展到了 32K 上下文。
2. 高效的预训练目标与模型架构：BatGPT-15B-sirius 采用双向自回归预训练目标，以提高对于训练数据的运用程度，并且基于 Multi-Query Attention 技术，在保证参数规模的前提下尽可能的减少推理显存的占用，提高推理速度。
3. 商业友好的开放协议：BatGPT-15B-sirius 的源码以及权重不仅支持自由的学术研究使用，也允许免费开源商用，助推大模型进一步帮助人类的日常生活。

BatGPT-15B-sirius is an open-source commercially available version of the series of large-scale language models BatGPT, designed, pretrained, and aligned by the joint natural language processing teams of Shanghai Jiao Tong University and Wuhan University (or Wuhan University and Shanghai Jiao Tong University, in no particular order).

The BatGPT series of models also include BatGPT-30B-orion, BatGPT-70B-alhena, and BatGPT-140B-menkalinan.

BatGPT-15B-sirius contains 15 billion parameters and has been pretrained on 1T Chinese and English corpora. It achieves excellent performance on authoritative Chinese and English benchmarks. BatGPT-15B-sirius has the following characteristics:

1. Supports Contexts Up to 32K Tokens: BatGPT-15B-sirius uses rotated positional encoding (RoPE) and is pretrained with a sequence length of 2048 tokens. During fine-tuning, it gradually expands to support contexts up to 32K tokens.
2. Efficient Pre-training Objectives and Model Architecture: BatGPT-15B-sirius employs a bidirectional autoregressive pretraining objective to better utilize the training data. It also utilizes the Multi-Query Attention technique to reduce inference memory consumption and improve inference speed while maintaining model size.
3. Business-friendly Open License: The source code and weights of BatGPT-15B-sirius are not only available for academic research but also allow free and open-source commercial use, further facilitating the integration of large language models into human daily life.

简易使用

如下是一个使用 BatGPT-15B-sirius 进行对话的示例:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("MLP-lab/BatGPT-15B-sirius", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("MLP-lab/BatGPT-15B-sirius", torch_dtype=torch.float16, trust_remote_code=True).cuda()
model = model.eval()
history = []
system_prompt = None # 你也可以指定系统提示
response, history = model.chat(tokenizer, "你好", history=history, system_prompt=system_prompt)
print(response)
response, history = model.chat(tokenizer, "介绍一下你自己", history=history, system_prompt=system_prompt)
print(response)

Here is an example of a conversation using BatGPT-15B-sirius:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("MLP-lab/BatGPT-15B-sirius", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("MLP-lab/BatGPT-15B-sirius", torch_dtype=torch.float16, trust_remote_code=True).cuda()
model = model.eval()
history = []
system_prompt = None # You can give a system prompt here.
response, history = model.chat(tokenizer, "Hello", history=history, system_prompt=system_prompt)
print(response)
response, history = model.chat(tokenizer, "Please introduce yourself", history=history, system_prompt=system_prompt)
print(response)
