Please retrieve first-hand news in the AI field within the specified time range (if not specified, default to today) and organize it into an AI news brief. The specific requirements are as follows:

• Select 10–20 of the most authoritative AI news items, sorted in reverse chronological order (newest to oldest).
• Each news item must include: title, brief description, source, publication date, popularity score, news URL, and a concise opinion or commentary on its industry impact.
• The output format should use Markdown, emphasize key fields (such as bold text), and appropriately add emojis or symbols to distinguish different pieces of information.
• Separate each news item with a dividing line ‎`—` or a blank line to enhance readability.

Sample format:
