Writer integration

WRITER is a platform to generate different language content. This example goes over how to use LangChain to interact with WRITER models.

Setup

To access WRITER models you’ll need to create a WRITER account, get an API key, and install the writer-sdk and langchain-community packages.

Head to WRITER AI Studio to sign up for WRITER and generate an API key. Once you’ve done this set the WRITER_API_KEY environment variable:

import getpass
import os

if not os.environ.get("WRITER_API_KEY"):
    os.environ["WRITER_API_KEY"] = getpass.getpass("Enter your Writer API key:")

The LangChain WRITER integration lives in the langchain-community package:

pip install -qU langchain-community writer-sdk

Now we can initialize our model object to interact with writer LLMs

from langchain_community.llms import Writer as WriterLLM

llm = WriterLLM(
    temperature=0.7,
    max_tokens=1000,
    # other params...
)

response_text = llm.invoke(input="Write a poem")

print(response_text)

stream_response = llm.stream(input="Tell me a fairytale")

for chunk in stream_response:
    print(chunk, end="")

WRITER support asynchronous calls via ainvoke() and astream() methods
