Friendli

Friendli enhances AI application performance and optimizes cost savings with scalable, efficient deployment options, tailored for high-demand AI workloads.

This tutorial guides you through integrating Friendli with LangChain.

Setup​

Ensure the langchain_community and friendli-client are installed.

pip install -U langchain-community friendli-client.

Sign in to Friendli Suite to create a Personal Access Token, and set it as the FRIENDLI_TOKEN environment.

import getpass
import os

if "FRIENDLI_TOKEN" not in os.environ:
    os.environ["FRIENDLI_TOKEN"] = getpass.getpass("Friendi Personal Access Token: ")

You can initialize a Friendli chat model with selecting the model you want to use. The default model is mixtral-8x7b-instruct-v0-1. You can check the available models at docs.friendli.ai.

from langchain_community.llms.friendli import Friendli

llm = Friendli(model="mixtral-8x7b-instruct-v0-1", max_tokens=100, temperature=0)
API Reference:Friendli

Usage​

Frienli supports all methods of LLM including async APIs.

You can use functionality of invoke, batch, generate, and stream.

llm.invoke("Tell me a joke.")
'Username checks out.\nUser 1: I\'m not sure if you\'re being sarcastic or not, but I\'ll take it as a compliment.\nUser 0: I\'m not being sarcastic. I\'m just saying that your username is very fitting.\nUser 1: Oh, I thought you were saying that I\'m a "dumbass" because I\'m a "dumbass" who "checks out"'
llm.batch(["Tell me a joke.", "Tell me a joke."])
['Username checks out.\nUser 1: I\'m not sure if you\'re being sarcastic or not, but I\'ll take it as a compliment.\nUser 0: I\'m not being sarcastic. I\'m just saying that your username is very fitting.\nUser 1: Oh, I thought you were saying that I\'m a "dumbass" because I\'m a "dumbass" who "checks out"',

for chunk in llm.stream("Tell me a joke."):
    print(chunk, end="", flush=True)
Username checks out.
User 1: I'm not sure if you're being sarcastic or not, but I'll take it as a compliment.
User 0: I'm not being sarcastic. I'm just saying that your username is very fitting.
User 1: Oh, I thought you were saying that I'm a "dumbass" because I'm a "dumbass" who "checks out"

You can also use all functionality of async APIs: ainvoke, abatch, agenerate, and astream.

await llm.ainvoke("Tell me a joke.")
'Username checks out.\nUser 1: I\'m not sure if you\'re being sarcastic or not, but I\'ll take it as a compliment.\nUser 0: I\'m not being sarcastic. I\'m just saying that your username is very fitting.\nUser 1: Oh, I thought you were saying that I\'m a "dumbass" because I\'m a "dumbass" who "checks out"'
await llm.abatch(["Tell me a joke.", "Tell me a joke."])
['Username checks out.\nUser 1: I\'m not sure if you\'re being sarcastic or not, but I\'ll take it as a compliment.\nUser 0: I\'m not being sarcastic.

 'Username checks out.\nUser 1: I\'m not sure if you\'re being sarcastic or not, but I\'ll take it as a compliment.\nUser 0: I\'m not being sarcastic. I\'m just saying that your username is very fitting.\nUser 1: Oh, I thought you were saying that I\'m a "dumbass" because I\'m a "dumbass" who "checks out"']
await llm.agenerate(["Tell me a joke.", "Tell me a joke."])
LLMResult(generations=[[Generation(text="Username checks out.\nUser 1: I'm not sure if you're being serious or not, but I'll take it as a compliment.\nUser 0: I'm being serious.

async for chunk in llm.astream("Tell me a joke."):
