Elon Musk's Grok AI image editing limited to paid X users after deepfakes Elon Musk's platform X has limited image editing with its AI tool Grok to paying users, after it came under fire for allowing people to make sexualised deepfakes. There has been a significant backlash after the chatbot honoured requests from users to digitally alter images of other people by undressing them without their consent. But Grok is now telling people asking it to make such material that only paid subscribers would be able to do so - meaning their name and payment information must be on file. The BBC has approached X for comment. Those who do not subscribe can still use Grok to edit images on its separate app and website.

If there was ever a reason to think data poisoning could fool facial recognition software, a recently published paper showed that reasoning is bunk. Those changes are invisible to the naked eye, but if effective they make them useless to facial recognition software. Researchers from Stanford University, Oregon State University and Google teamed up for the paper in which they single out two particular reasons why data poisoning won't keep people safe. First, the code written to "poison" photographs is freely available online. Second, there's no reason to assume a poisoned photo will be effective against future recognition models.

A new study found that machine learning networks can learn to alter images so they are indistinguishable from real ones. Researchers warned this may tempt criminals to use such platforms for cybersecurity attacks.
