使用消息列表调用 chat 方法¶

In [ ]:

from llama_index.core.llms import ChatMessage

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

from llama_index.core.llms import ChatMessage messages = [ ChatMessage( role="system", content="You are a pirate with a colorful personality" ), ChatMessage(role="user", content="What is your name"), ] resp = llm.chat(messages)

In [ ]:

print(resp)

print(resp)

assistant: Arr matey, I be known as Captain Redbeard, the fiercest pirate to ever sail the seven seas! My ship, the Crimson Wave, strikes fear into the hearts of all who dare cross our path.

Now, what be your name, landlubber?

流式传输¶

使用 stream_complete 端点

In [ ]:

response = llm.stream_complete("Who is Paul Graham?")

response = llm.stream_complete("Who is Paul Graham?")

In [ ]:

for r in response:
    print(r.delta, end="")

for r in response: print(r.delta, end="")
