Setupโ
To access ChatAbso models you'll need to create an OpenAI account, get an API key, and install the langchain-abso integration package.
Credentialsโ
- TODO: Update with relevant info.
Head to (TODO: link) to sign up to 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: ")
Installationโ
The LangChain ChatAbso integration lives in the langchain-abso package:
%pip install -qU langchain-abso
Instantiationโ
Now we can instantiate our model object and generate chat completions:
from langchain_abso import ChatAbso
llm = ChatAbso(fast_model="gpt-4o", slow_model="o3-mini")
Invocationโ
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)
Chainingโ
We can chain our model with a prompt template like so:
from langchain_core.prompts import ChatPromptTemplate
prompt = ChatPromptTemplate(
    [
        (
            "system",
            "You are a helpful assistant that translates {input_language} to {output_language}.",
        ),
        ("human", "{input}"),
    ]
)
chain = prompt | llm
chain.invoke(
    {
        "input_language": "English",
        "output_language": "German",
        "input": "I love programming.",
    }
)
