Konko

Konko API 是一个完全托管的Web API，旨在帮助应用开发人员：

  1. 选择适合其应用的正确开源或专有大型语言模型
  2. 构建应用程序更快，与领先的应用框架集成并使用完全托管的 API
  3. 微调较小的开源大语言模型，以极低的成本实现行业领先的性能
  4. 部署生产级 API，利用 Konko AI 符合 SOC 2 标准的多云基础设施，无需进行基础设施设置或管理，即可满足安全、隐私、吞吐量和延迟 SLA 要求

这个示例介绍了如何使用LangChain与Konko聊天完成模型进行交互。 模型链接

要运行此笔记本，您需要 Konko API 密钥。请登录我们的网络应用以创建 API 密钥来访问模型

from langchain_community.chat_models import ChatKonko
from langchain_core.messages import HumanMessage, SystemMessage

设置环境变量​

  1. 您可以设置环境变量：
    1. KONKO_API_KEY（必需）
    2. OPENAI_API_KEY（可选）
  2. 在当前的shell会话中，使用export命令:
export KONKO_API_KEY={your_KONKO_API_KEY_here}
export OPENAI_API_KEY={your_OPENAI_API_KEY_here} #Optional

调用一个模型​

在Konko概览页面上找到一个模型

在Konko实例上查找运行模型列表的另一种方式是通过此端点。

从此，我们可以初始化我们的模型：<br>

chat = ChatKonko(max_tokens=400, model="meta-llama/llama-2-13b-chat")
messages = [
    SystemMessage(content="You are a helpful assistant."),
    HumanMessage(content="Explain Big Bang Theory briefly"),
]
chat(messages)
AIMessage(content="  Sure thing! The Big Bang Theory is a scientific theory that explains the origins of the universe. In short, it suggests that the universe began as an infinitely hot and dense point around 13.8 billion years ago and expanded rapidly. This expansion continues to this day, and it's what makes the universe look the way it does.\n\nHere's a brief overview of the key points:\n\n1. The universe started as a singularity, a point of infinite density and temperature.\n2. The singularity expanded rapidly, causing the universe to cool and expand.\n3. As the universe expanded, particles began to form, including protons, neutrons, and electrons.\n4. These particles eventually came together to form atoms, and later, stars and galaxies.\n5. The universe is still expanding today, and the rate of this expansion is accelerating.\n\nThat's the Big Bang Theory in a nutshell! It's a pretty mind-blowing idea when you think about it, and it's supported by a lot of scientific evidence. Do you have any other questions about it?")
