模型介绍/Introduction

BlueLM 是由 vivo AI 全球研究院自主研发的大规模预训练语言模型,本次发布包含 7B 基础模型和 7B 对话模型,同时我们开源了支持 32K 的长文本基础模型和对话模型。

  • 更大量的优质数据:高质量语料库进行训练,规模达到了 2.6 万亿 的 token 数,该语料库包含中文、英文以及少量日韩数据。
  • 更优的效果:其中 BlueLM-7B-Chat 在 C-EvalCMMLU 上均取得领先结果,对比同尺寸开源模型中具有较强的竞争力。
  • 长文本支持:BlueLM-7B-Base-32K 和 BlueLM-7B-Chat-32K 均支持 32K 长文本,在保持基础能力相当情况下,能够支持更长上下文理解。
  • 协议说明:BlueLM 系列欢迎开发者进行学术研究和商业应用。

BlueLM is a large-scale open-source language model independently developed by the vivo AI Lab. This release includes 2K and 32K context length versions for both Base and Chat models.

  • High-quality Data: BlueLM is trained on a high-quality data with 2.6 trillion tokens. Our train corpus mainly consists of Chinese and English data, with a small amount of Japanese and Korean data.
  • Stronger Performance: BlueLM-7B-Chat achieves a strong competitive performance in C-Eval and CMMLU benchmarks of the same size.
  • Longer Context: We have extended the context length of both BlueLM-7B-Base-32K and BlueLM-7B-Chat-32K models from 2K to 32K. The models can support longer context understanding while maintaining the same basic capabilities.
  • Model License: BlueLM weights are open for academic research and commercial use.

推理部署/Inference and Deployment

>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> tokenizer = AutoTokenizer.from_pretrained("vivo-ai/BlueLM-7B-Base-32K", trust_remote_code=True, use_fast=False)
>>> model = AutoModelForCausalLM.from_pretrained("vivo-ai/BlueLM-7B-Base-32K", device_map="cuda:0", torch_dtype=torch.bfloat16, trust_remote_code=True)
>>> model = model.eval()
>>> inputs = tokenizer("儒林外史->吴敬梓\n隋唐演义->褚人获\n红楼梦->", return_tensors="pt")
>>> inputs = inputs.to("cuda:0")
>>> pred = model.generate(**inputs, max_new_tokens=64, repetition_penalty=1.1)
>>> print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))
儒林外史->吴敬梓
