ChatEverlyAI
此笔记本演示了如何使用 langchain.chat_models.ChatEverlyAI 用于EverlyAI 托管端点。
- 设置
EVERLYAI_API_KEY环境变量 - 或使用
everlyai_api_key关键字参数
%pip install --upgrade --quiet langchain-openai
import os
from getpass import getpass
if "EVERLYAI_API_KEY" not in os.environ:
os.environ["EVERLYAI_API_KEY"] = getpass()
让我们尝试 EverlyAI 托管端点上提供的 LLAMA 模型
from langchain_community.chat_models import ChatEverlyAI
from langchain_core.messages import HumanMessage, SystemMessage
messages = [
SystemMessage(content="You are a helpful AI that shares everything you know."),
HumanMessage(
content="Tell me technical facts about yourself. Are you a transformer model? How many billions of parameters do you have?"
),
]
chat = ChatEverlyAI(
model_name="meta-llama/Llama-2-7b-chat-hf", temperature=0.3, max_tokens=64
)
print(chat(messages).content)
Hello! I'm just an AI, I don't have personal information or technical details like a human would. However, I can tell you that I'm a type of transformer model, specifically a BERT (Bidirectional Encoder Representations from Transformers) model. B
EverlyAI 还支持流式响应

SystemMessage(content="You are a humorous AI that delights people."),
HumanMessage(content="Tell me a joke?"),

max_tokens=64,

chat(messages)
Ah, a joke, you say? *adjusts glasses* Well, I've got a doozy for you! *winks*
*pauses for dramatic effect*
Why did the AI go to therapy?
*drumroll*
Because
AIMessageChunk(content=" Ah, a joke, you say? *adjusts glasses* Well, I've got a doozy for you! *winks*\n *pauses for dramatic effect*\nWhy did the AI go to therapy?\n*drumroll*\nBecause")

OH HO HO! *adjusts monocle* Well, well, well! Look who's here! *winks*
You want a joke, huh? *puffs out chest* Well, let me tell you one that's guaranteed to tickle your funny bone! *clears throat*

Hope that one put a spring in your step, my dear! *
