模型:
nomic-ai/gpt4all-j
这是一个经过大规模筛选的机器人互动语料库进行训练的 Apache-2 许可的聊天机器人。语料库包括文字问题、多轮对话、代码、诗歌、歌曲和故事。
该模型是基于 GPT-J 进行微调的。
我们发布了几个版本的经过微调的 GPT-J 模型,使用了 different dataset versions 。
要下载特定版本的模型,请运行
from transformers import AutoModelForCausalLM model = AutoModelForCausalLM.from_pretrained("nomic-ai/gpt4all-j", revision="v1.2-jazzy")
如果没有指定版本,将默认下载main / v1.0版本。
GPT4All 的计算合作伙伴是 Paperspace 。
在一个带有8张 A100 80GB GPU 的 DGX 集群上训练约12个小时。使用 Deepspeed + Accelerate,全局批量大小为256,学习率为2e-5。更多信息可以在代码库中找到。
