The Friday File: Mobile World Live brings you our top three picks of the week as Meta postponed the international release of its latest Ray-Ban smart glasses, Nvidia unveiled a new family of models and X’s AI tool Grok faced regulatory fire.

Meta delays latest international AI glasses launch

What happened: Meta Platforms postponed the international release of its latest Ray-Ban branded spectacles originally scheduled for early 2026, blaming limited stock and high demand in the US where the wearable is already available.

Why it matters: The Meta Ray-Ban Display model launched in the US during September 2025. At the time, the company expected to release the device in the UK, Canada, France and Italy early this year.  However, in a product update released at CES 2026 this week, Meta Platforms noted the “first-of-its-kind product” had “extremely limited inventory”, with waiting lists for the spectacles extending well into this year.

Nvidia unveils family of open AI models for AVs, robots

What happened: Nvidia took the wraps off a family of open AI models, simulation tools and datasets at CES 2026 in Las Vegas, designed to usher in a new era for autonomous vehicles (AV) and robotics.

Why it matters: During a keynote address, Nvidia CEO Jensen Huang stated the company’s new Alphamayo family of open-source AI models is “the world’s first thinking, reasoning, autonomous vehicle AI”. Huang stated the goal of Alpamayo is to bring humanlike thinking to AV decision-making while also applying the same technologies to train and operate physical robots. The new models could potentially setup an autonomous car rivalry with Elon Musk-owned Tesla, but Richard Windsor,founder of Radio Free Mobile, expressed doubt.” I still do not think that an end-to-end model where sensor data goes in one end, and driving instructions pop out of the other will ever produce a commercially viable, fully hands-off autonomous driving solution,” he stated.

X under fire over indecent Grok imagery

What happened: Regulators reportedly ramped pressure on Elon Musk’s X to address the spread of sexualised images of people across the social media platform, generated on-demand by its in-built AI tool Grok.

Why it matters: Reuters reported the European Commission (EC) described the sharing of images of undressed women and children across X as unlawful and appalling, adding to concerns raised from politicians across the world. “Tools like Grok now risk bringing sexual AI imagery of children into the mainstream,” Ngaire Alexander, head of the reporting hotline at the UK-based Internet Watch Foundation, stated. “There is no excuse for releasing products to the global public which can be used to abuse and hurt people, especially children.”
