from langchain_community.llms import AlephAlpha
from langchain_core.prompts import PromptTemplate
API Reference:PromptTemplate
template = """Q: {question}

A:"""

prompt = PromptTemplate.from_template(template)
llm = AlephAlpha(
    model="luminous-extended",
    maximum_tokens=20,
    stop_sequences=["Q:"],
    aleph_alpha_api_key=ALEPH_ALPHA_API_KEY,
)
llm_chain = prompt | llm
question = "What is AI?"

llm_chain.invoke({"question": question})
' Artificial Intelligence is the simulation of human intelligence processes by machines.\n\n'
