集成详情
模型特性
要访问 Groq 模型,您需要创建一个 Groq 账户,获取 API 密钥,并安装 langchain-groq 集成包。
前往 Groq 控制台 注册 Groq 并生成 API 密钥。完成后,设置 GROQ_API_KEY 环境变量:
import getpass
import os
if "GROQ_API_KEY" not in os.environ:
os.environ["GROQ_API_KEY"] = getpass.getpass("输入您的 Groq API 密钥:")
要启用模型调用的自动追踪,请设置您的 LangSmith API 密钥:
os.environ["LANGSMITH_API_KEY"] = getpass.getpass("输入您的 LangSmith API 密钥:")
os.environ["LANGSMITH_TRACING"] = "true"
LangChain Groq 集成位于 langchain-groq 包中:
pip install -qU langchain-groq
实例化
现在我们可以实例化模型对象并生成聊天补全。
推理格式如果您选择设置 reasoning_format,必须确保您使用的模型支持它。您可以在 Groq 文档 中找到支持的模型列表。
from langchain_groq import ChatGroq
llm = ChatGroq(
model="qwen/qwen3-32b",
temperature=0,
max_tokens=None,
reasoning_format="parsed",
timeout=None,
max_retries=2,
# 其他参数...
)
messages = [
(
"system",
"您是一个将英语翻译成法语的助手。请翻译用户的句子。",
),
("human", "I love programming."),
]
ai_msg = llm.invoke(messages)

AIMessage(content="J'aime la programmation.", additional_kwargs={'reasoning_content': 'Okay, so I need to translate the sentence "I love programming." into French. Let me think about how to approach this. \n\nFirst, I know that "I" in French is "Je." That\'s straightforward. Now, the verb "love" in French is "aime" when referring to oneself. So, "I love" would be "J\'aime." \n\nNext, the word "programming." In French, programming is "la programmation." But wait, in French, when you talk about loving an activity, you often use the definite article. So, it would be "la programmation." \n\nPutting it all together, "I love programming" becomes "J\'aime la programmation." That sounds right. I think that\'s the correct translation. \n\nI should double-check to make sure I\'m not missing anything. Maybe I can think of similar phrases. For example, "I love reading" is "J\'aime lire," but when it\'s a noun, like "I love music," it\'s "J\'aime la musique." So, yes, using "la programmation" makes sense here. \n\nI don\'t think I need to change anything else. The sentence structure in French is Subject-Verb-Object, just like in English, so "J\'aime la programmation" should be correct. \n\nI guess another way to say it could be "J\'adore la programmation," using "adore" instead of "aime," but "aime" is more commonly used in this context. So, sticking with "J\'aime la programmation" is probably the best choice.\n'}, response_metadata={'token_usage': {'completion_tokens': 346, 'prompt_tokens': 23, 'total_tokens': 369, 'completion_time': 1.447541218, 'prompt_time': 0.000983386, 'queue_time': 0.009673684, 'total_time': 1.448524604}, 'model_name': 'deepseek-r1-distill-llama-70b', 'system_fingerprint': 'fp_e98d30d035', 'finish_reason': 'stop', 'logprobs': None}, id='run--5679ae4f-f4e8-4931-bcd5-7304223832c0-0', usage_metadata={'input_tokens': 23, 'output_tokens': 346, 'total_tokens': 369})
视觉功能
Groq 支持特定模型的视觉功能,允许您发送图像以及文本提示。
