LangChain AI开发框架增强了AI应用性能并优化了成本节约，提供可扩展且高效的部署选项，特别针对高需求的AI工作负载。
本教程将指导您完成将 Friendli 与 LangChain 集成的过程。
设置
请确保安装了langchain_community和friendli-client。
pip install -U langchain-community friendli-client
请登录Friendli Suite以创建一个个人访问令牌，并将其设置为FRIENDLI_TOKEN环境变量。
import getpass
import os
if "FRIENDLI_TOKEN" not in os.environ:
os.environ["FRIENDLI_TOKEN"] = getpass.getpass("Friendi Personal Access Token: ")
您可以选择要使用的模型来初始化 Friendli 聊天模型。
默认模型是 meta-llama-3.1-8b-instruct. 您可以在以下位置查看可用的模型：friendli.ai/docs.
from langchain_community.llms.friendli import Friendli
llm = Friendli(model="meta-llama-3.1-8b-instruct", max_tokens=100, temperature=0)
API 参考:友利
用法
Frienli 支持所有 LLM 的方法，包括异步 API。
您可以使用 invoke、batch、generate 和 stream 的功能。
llm.invoke("Tell me a joke.")
" I need a laugh.\nHere's one: Why couldn't the bicycle stand up by itself?\nBecause it was two-tired!\nI hope that made you laugh! Do you want to hear another one? I have a million of 'em! (Okay, maybe not a million, but I have a few more where that came from!) What kind of joke are you in the mood for? A pun, a play on words, or something else? Let me know and I'll try to come"
llm.batch(["Tell me a joke.", "Tell me a joke."])
[" I need a laugh.\nHere's one: Why couldn't the bicycle stand up by itself?\nBecause it was two-tired!\nI hope that made you laugh! Do you want to hear another one? I have a million of 'em!

llm.generate(["Tell me a joke.", "Tell me a joke."])

print(chunk, end="", flush=True)
您还可以使用所有异步API的功能：ainvoke，abatch，agenerate 和 astream。
await llm.ainvoke("Tell me a joke.")
