Bing experiments with the AI Mode button position in search tabs

Bing appears to be testing a different placement for its AI Mode button within the search tabs. The usual layout displays the button in its existing position, while the test version shows it in a different location.

I spotted this variation while browsing Bing Search. Comparing both screenshots shows the change in how the AI Mode option is positioned alongside the search navigation tabs.

Here is how the test version looks.

Here is how the search tabs usually look.

However, the new placement may create some confusion for users, as the AI Mode button appears in a different position from the usual search navigation layout. What do you think about this change?
