Tennessee minors sue Musk's xAI, alleging Grok generated sexual images of them Governments and regulators around the world have launched probes into xAI, imposed bans and demanded safeguards in a growing push to curb illegal and offensive material. Three Tennessee plaintiffs, including two minors, sued Elon Musk's xAI on Monday, alleging that it knowingly designed its Grok image generator to let people create sexually explicit content by using real photos of others. The lawsuit, filed in the San Jose, California federal court, is seeking class-action status for people in the United States who were reasonably identifiable in sexualized images or videos generated by Grok based on real images of themselves. The artificial intelligence company did not immediately respond to a request for comment. After an outcry over sexually explicit content generated by the chatbot, xAI said in January that it had blocked all users from editing images of real people in revealing clothing and from generating images of people in revealing clothing in jurisdictions where it's illegal. Governments and regulators around the world have also since launched probes, imposed bans and demanded safeguards in a growing push to curb illegal and offensive material.

The encyclopedia company's lawsuit also said ChatGPT cannibalizes traffic to the Britannica and Merriam-Webster websites. OpenAI has been hit with another lawsuit. According to the lawsuit, ChatGPT generates made-up content or ' hallucinations ' and falsely attributes them to Encyclopedia Britannica. The lawsuit doesn't specify an amount for monetary damages, but Britannica is also seeking an injunction to prevent OpenAI from repeating these accusations. When reached out for comment, a spokesperson for OpenAI told Engadget that, ChatGPT helps enhance human creativity, advance scientific discovery and medical research, and enable hundreds of millions of people to improve their daily lives.

Amazon is replacing its $2.99 ad-free Prime Video add-on with'Prime Video Ultra' at $4.99 monthly, representing a 66% price increase for ad-free viewing. PCWorld reports that 4K streaming will become exclusive to Ultra subscribers starting April 10, 2025, while standard Prime members lose 4K but gain Dolby Vision support. The Ultra plan includes five concurrent 4K streams and 100 offline downloads, significantly raising costs for users wanting premium streaming features. It's been a little more than two years since Amazon started charging extra for ad-free Prime Video streaming, and now that we've gotten used to the extra fee, it's time for a price hike. Amazon just announced that its $2.99-a-month add-on for removing ads from Prime Video is morphing into a new plan called Prime Video Ultra, which will set you back $4.99 a month. That's a 66-percent price hike for monthly subscribers who formerly opted for the cheaper ad-free add-on. An annual subscription for Prime Video Ultra costs $45.99, a 23-percent discount compared to the new plan's monthly rate. Slated to arrive April 10, Prime Video Ultra will come with a few added benefits besides stripping away most ads (live sports and other programming will still have commercial breaks), including up to five concurrent 4K streams (up from the original limit of three) and up to 100 offline downloads (up from 25). At the same time, standard Prime members (who get Prime Video with ads included in their subscriptions, which cost $14.99 a month or $139 a year) will see some changes too, including added support for Dolby Vision HDR, an additional concurrent video stream (for a total of 4) and double the amount of offline downloads compared to the former 25-download limit.

Writing tool Grammarly has disabled an AI feature which mimicked personas of prominent writers, including Stephen King and scientist Carl Sagan, following a backlash from people impersonated. The Expert Review function, which offered writing feedback inspired by the styles of famous authors and academics, was taken down this week by Superhuman, the tech firm which runs Grammarly. The feature was met with resistance, including a multi-million dollar lawsuit, from writers who found their names and reputations used as AI personas without their consent. Shishir Mehrotra, the firm's chief executive, apologised on LinkedIn, acknowledging the tool had misrepresented the voices of experts. Investigative journalist Julia Angwin, a New York Times contributing opinion writer, is the lead plaintiff in a class-action lawsuit filed against Superhuman and Grammarly in the Southern District of New York.

A short-lived AI tool promised to help users write like the greats--and a bunch of other random people, including me. T o me, the best first sentence of any piece of journalism is the one in Joan Didion's 1987 book,, which begins like this: "Havana vanities come to dust in Miami." I love that sentence and that propulsive first chapter so much that I once sat down to try to figure out how she did it. I looked at the sentences one at a time to assess what purpose each one was serving, and I counted how many of them Didion had needed to accomplish each thing she wanted to accomplish. Then I thought about how she figured out what order to put them in to have maximum page-turning impact.

The core premise of Expert Review needed some expert review. Superhuman has taken its writing assistant Grammarly on quite the merry-go-round ride regarding its approach to AI tools. In August, the company launched a feature called Expert Review that would offer feedback on your writing, offering AI-generated feedback that would appear to come from a famous writer or academic of note. These recreations were based on publicly available information from third-party LLMs, which sounds a lot like web crawlers of dubious legality were involved. The suggested experts would be based on the subject matter and could be anyone from great scientific minds to bestselling fiction authors to your friendly neighborhood tech bloggers.

In Algorithm 1 we present the memorizing and recalling procedures of the single-layer tPC.Algorithm 1 Memorizing and recalling with single-layer tPC Here we present the proof for Property 1 in the main text, that the single-layer tPC can be viewed as a "whitened" version of the AHN. When applied to the data sequence, it whitens the data such that (i.e., Eq.16 in the main text): These observations are consistent with our numerical results shown in Figure 1. MCAHN has a much larger MSE than that of the tPC because of the entirely wrong recalls. In Figure 1 we also present the online recall results of the models in MovingMNIST, CIFAR10 and UCF101. In Fig 4 we show a natural example of aliased sequences where a movie of a human doing push-ups is memorized and recalled by the model.
