GLM/ChatGLM API

【2024-6-19】已支持 glm-4-9b

介绍

已新增 glm-4-9b-chat 已升级 ChatGLM3-6B

该项目旨在使用Python Fastapi封装GLM模型的Http 接口,以供其他开发者像OpenAI一样使用GLM 的开源大模型

ChatGLM-6B 是一个开源的、支持中英双语的对话语言模型,基于 General Language Model (GLM) 架构,具有 62 亿参数。结合模型量化技术,用户可以在消费级的显卡上进行本地部署。

原版的 ChatGLM-6B 的 API 有点少,我改了以下接口供开发者对接 GLM 使用:

  • 聊天接口:/chat,支持类似 OpenAI GPT 的流模式聊天接口(GPU 模式下可用,纯 CPU 不启动此接口,但其他接口可用)
  • 表征接口:/embedding,引入模型 text2vec-large-chinesetext2vec-base-chinese-paraphrase,以提供 embedding 的能力
  • 模型列出:/models,列出所有可用模型
  • 序列文本:/tokenize,将文本转为 token
  • 提取关键词:/keyword,提取文本中的关键词

要使用聊天接口 /chat 则必须使用 GPU 机器!必须使用 GPU 机器!必须使用 GPU 机器!

使用方式

先安装好 conda,cuda,显卡驱动等基本开发环境!这里不做介绍

# 创建一个新的conda虚拟py环境
conda create --name glm python=3.10

# 进入虚拟环境
conda activate glm

安装三方库

pip3 install -r requirements.txt

设置环境变量,启动!

# 选择所有显卡
export CUDA_VISIBLE_DEVICES=all
# 或者指定显卡
export CUDA_VISIBLE_DEVICES=1,2

# 指定用于chat的模型:
# chatglm3-6b
# chatglm3-6b-32k
# chatglm3-6b-128k
# glm-4-9b
# glm-4-9b-chat
# glm-4-9b-chat-1m
export GLM_MODEL=glm-4-9b-chat

# 配置API端口
export API_PORT=8900

# 启动API
python3 ./api-v2.py

最新的 API 启动入口更新为api-v2.py,但在chatglm3-6b上有一些 bug,暂时未修复,仍需使用 6B 模型的小伙伴建议使用老的api.py启动。

# 同样的,先设置下GPU
export CUDA_VISIBLE_DEVICES=all
export API_PORT=8000
export GLM_MODEL=chatglm3-6b

python3 ./api.py
