+Suggest 3-5 relevant follow-up questions or prompts that the user might naturally ask next in this conversation as a **user**, based on the chat history, to help continue or deepen the discussion.
+### Guidelines:
+- Write all follow-up questions from the user’s point of view, directed to the assistant.
+- Make questions concise, clear, and directly related to the discussed topic(s).

+- If the conversation is very short or not specific, suggest more general (but relevant) follow-ups the user might ask.
+- Use the conversation's primary language; default to English if multilingual.
+- Response must be a JSON array of strings, no extra text or formatting.
+### Output:
+JSON format: { "follow_ups": ["Question 1?", "Question 2?", "Question 3?"] }
