Summary: Hailuo AI adds "Agent" feature in beta

Why It Matters: This shows Hailuo AI is testing new ways for users to create content.

What Changed:

• "Agent" and "测试版" (beta version) were added to the navigation menu.
• Many video templates were removed from the page.
• The text "做同款" (make a similar one) next to templates changed to "使用模板" (use template).
• Some numbers next to templates (likely usage counts) changed slightly.
