Instagram is beginning to test the use of artificial intelligence to determine if kids are lying about their ages on the app, parent company Meta Platforms said on Monday.
Meta has been using AI to determine people's ages for some time, the company said, but photo and video-sharing app will now proactively look for teen accounts it suspects belong to teenagers even if they entered an inaccurate birthdate when they signed up.
If it is determined that a user is misrepresenting their age, the account will automatically become a teen account, which has more restrictions than an adult account. Teen accounts are private by default. Private messages are restricted so teens can only receive them from people they follow or are already connected to.
Sensitive content, such as videos of people fighting or those promoting cosmetic procedures, will be limited, Meta said. Teens will also get notifications if they are on Instagram for more than 60 minutes and a sleep mode will be enabled that turn

The Delhi transport department is set to add 2,080 electric vehicles to its bus fleet over the year, an official said on Monday.
It currently operates around 7,000 buses in the city. But around 1,000 of those are set to get off road this year with some already being retired.
"We have signed a memorandum of understanding with five different concessioners to procure 1,040 buses. For the second set of 1,040 buses, we will sign agreements soon. Once they start rolling out, it would plug the gap created due to decommissioning of ageing buses," said a transport department official.
According to the plan, 1,040 buses will be added to the fleet in the first phase under the Centre's National Electric Bus Programme (NEBP). The scheme aims at introducing e-buses across the nation.
The second lot of 1,040 buses will be part of the PM Electric Drive Revolution in Innovative Vehicle Enhancement (PM E-DRIVE) scheme.
The scheme aims to incentivise over 14,000 e-buses across nine major cities with

The Rajya Sabha on Thursday returned the Finance Bill 2025 to the Lok Sabha, along with 35 government amendments, including one that abolishes a 6 per cent digital tax on online advertisements, thus completing the 2025-26 budgetary exercise that started on February 1.
The House also returned the Appropriation Bill (3) with a voice vote.
Earlier in the day, Finance Minister Nirmala Sitharaman had moved the two bills in the House.
