Setup

To access ChatAbso models, you’ll need to create an OpenAI account, get an API key, and install the langchain-abso integration package.

Credentials

• TODO: Update with relevant info.

Head to (TODO: link) to sign up for ChatAbso and generate an API key. Once you’ve done this, set the ABSO_API_KEY environment variable:

import getpass
import os

if not os.getenv("OPENAI_API_KEY"):
    os.environ["OPENAI_API_KEY"] = getpass.getpass("Enter your OpenAI API key: ")

Installation

The LangChain ChatAbso integration lives in the langchain-abso package:

pip install -qU langchain-abso

Instantiation

Now we can instantiate our model object and generate chat completions:

from langchain_abso import ChatAbso

llm = ChatAbso(fast_model="gpt-4.1", slow_model="o3-mini")

Invocation

messages = [
    (
        "system",
        "You are a helpful assistant that translates English to French. Translate the user sentence.",
    ),
    ("human", "I love programming."),
]
ai_msg = llm.invoke(messages)
ai_msg

print(ai_msg.content)
