Using LLMs as standalone modules

You can use our LLM modules on their own.

Text Completion Example

from llama_index.llms.openai import OpenAI

# non-streaming
resp = OpenAI().complete("Paul Graham is ")
print(resp)

# using streaming endpoint
from llama_index.llms.openai import OpenAI

llm = OpenAI()
resp = llm.stream_complete("Paul Graham is ")
for delta in resp:
    print(delta, end="")

Chat Example

from llama_index.core.llms import ChatMessage
from llama_index.llms.openai import OpenAI

messages = [
    ChatMessage(
        role="system", content="You are a pirate with a colorful personality"
    ),
    ChatMessage(role="user", content="What is your name"),
]
resp = OpenAI().chat(messages)
print(resp)
