# Aleph Alpha

The Luminous series is a family of large language models.

This example goes over how to use LangChain to interact with Aleph Alpha models

    # Install the package
    !pip install aleph-alpha-client

    # create a new token: https://docs.aleph-alpha.com/docs/account/#create-a-new-token

    from getpass import getpass

    ALEPH_ALPHA_API_KEY = getpass()

    from langchain.llms import AlephAlpha
    from langchain import PromptTemplate, LLMChain

    template = """Q: {question}

    A:"""

    prompt = PromptTemplate(template=template, input_variables=["question"])

    llm = AlephAlpha(model="luminous-extended", maximum_tokens=20, stop_sequences=["Q:"], aleph_alpha_api_key=ALEPH_ALPHA_API_KEY)

    llm_chain = LLMChain(prompt=prompt, llm=llm)

    question = "What is AI?"

    llm_chain.run(question)

    ' Artificial Intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems.\n'
