Fireworks
This page covers how to use Fireworks models within Langchain.
Installation and setup
-
Install the Fireworks integration package.
pip install langchain-fireworks -
Get a Fireworks API key by signing up at fireworks.ai.
-
Authenticate by setting the FIREWORKS_API_KEY environment variable.
Authentication
There are two ways to authenticate using your Fireworks API key:
-
Setting the
FIREWORKS_API_KEYenvironment variable.os.environ["FIREWORKS_API_KEY"] = "<KEY>" -
Setting
api_keyfield in the Fireworks LLM module.llm = Fireworks(api_key="<KEY>")
Using the Fireworks LLM module
Fireworks integrates with Langchain through the LLM module. In this example, we will work the mixtral-8x7b-instruct model.
from langchain_fireworks import Fireworks
llm = Fireworks(
api_key="<KEY>",
model="accounts/fireworks/models/mixtral-8x7b-instruct",
max_tokens=256)
llm("Name 3 sports.")
