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 meta-llama-3.1-8b-instruct. You can check the available models at 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 Reference:Friendli

Usage​

Frienli supports all methods of LLM including async APIs.

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

" 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!

    print(chunk, end="", flush=True)

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

await llm.ainvoke("Tell me a joke.")
