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}) ``` ```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} print(ai_msg.content) ``` ```text theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} J'aime la programmation. ``` ## 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。 **支持视觉的模型** * `meta-llama/llama-4-scout-17b-16e-instruct` * `meta-llama/llama-4-maverick-17b-128e-instruct` 有关最新支持视觉的模型列表，请查看 [Groq 文档](https://console.groq.com/docs/vision)。 ```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} from langchain_groq import ChatGroq from langchain.messages import HumanMessage llm = ChatGroq(model="meta-llama/llama-4-scout-17b-16e-instruct") message = HumanMessage( content=[ {"type": "text", "text": "详细描述这张图片。"}, { "type": "image_url", "image_url": {"url": "https://example.com/image.jpg"}, }, ] ) response = llm.invoke([message]) print(response.content) ``` **图像 URL 要求** Groq 直接从 URL 获取图像。请确保您的图像 URL： * 可公开访问（无需身份验证） * 直接返回图像（无重定向） * 最大图像大小：每个请求 20MB *** ## API 参考 有关 `ChatGroq` 所有功能和配置的详细文档，请前往 [API 参考](https://reference.langchain.com/python/langchain-groq/chat_models/ChatGroq)。 ***
