Together AI 提供了一个 API,可在几行代码中查询50 多个领先的开源模型。
本示例介绍了如何使用 LangChain 与 Together AI 模型进行交互。
安装
%pip install --upgrade langchain-together
环境
要使用 Together AI,您需要一个 API 密钥,您可以在此处找到:https://api.together.ai/settings/api-keys。这可以作为初始化参数 together_api_key
传递,也可以设置为环境变量 TOGETHER_API_KEY
。
示例
# Querying chat models with Together AI
from langchain_together import ChatTogether
# choose from our 50+ models here: https://docs.together.ai/docs/inference-models
chat = ChatTogether(
# together_api_key="YOUR_API_KEY",
model="meta-llama/Llama-3-70b-chat-hf",
)
# stream the response back from the model
for m in chat.stream("Tell me fun things to do in NYC"):
print(m.content, end="", flush=True)
# if you don't want to do streaming, you can use the invoke method
# chat.invoke("Tell me fun things to do in NYC")
# Querying code and language models with Together AI
from langchain_together import Together
llm = Together(
model="codellama/CodeLlama-70b-Python-hf",
# together_api_key="..."
)
print(llm.invoke("def bubble_sort(): "))
