0. 背景

最近有同事想玩玩 SalesGPT，结果发现使用 OpenAI API 时，会发生超过 Limit 的问题无法继续对话。

今天尝试通过本地部署开源大语言模型 Mixtral 8*7B，看看能不能将 SalesGPT 的对话持续下去。

1. SalesGPT 项目介绍

SalesGPT - 开源人工智能销售代理，此项目是使用 LLMs 实现上下文感知 AI 销售代理，可以跨语音、电子邮件和短信（短信、WhatsApp、微信、微博、电报等）工作。

SalesGPT 具有上下文感知能力，这意味着它可以了解当前处于销售对话的哪个阶段并采取相应的行动。此外，SalesGPT 可以访问工具，例如您自己的预定义产品知识库，从而显著减少幻觉。

2. SalesGPT 项目 Github 地址

https://github.com/filip-michalsky/SalesGPT

3. 本地部署 SalesGPT

克隆代码，

git clone https://github.com/filip-michalsky/SalesGPT; cd SalesGPT

创建一个虚拟环境，

poetry env use python

安装依赖库，

poetry install

4. 运行 SalesGPT

创建 .env 文件，

cp .env.example .env

修改 .env 文件，示例如下，

OPENAI_API_KEY="EMPTY"
OPENAI_API_BASE="http://<本地 LLM 的 IP 地址>:8000/v1"
LANGCHAIN_SMITH_API_KEY="ls__ToDo"

运行示例，

python run.py --verbose True --config examples/example_agent_setup.json

输出如下，
