Meta Opens Quest OS To Third Parties, Including ASUS and Lenovo

Par : msmash
22 avril 2024 à 19:20
In a huge move for the mixed reality industry, Meta announced today that it's opening the Quest's operating system to third-party companies, allowing them to build headsets of their own. From a report: Think of it like moving the Quest's ecosystem from an Apple model, where one company builds both the hardware and software, to more of a hardware free-for-all like Android. The Quest OS is being rebranded to "Meta Horizon OS," and at this point it seems to have found two early adopters. ASUS's Republic of Gamers (ROG) brand is working on a new "performance gaming" headsets, while Lenovo is working on devices for "productivity, learning and entertainment." (Don't forget, Lenovo also built the poorly-received Oculus Rift S.) As part of the news, Meta says it's also working on a limited-edition Xbox "inspired" Quest headset. (Microsoft and Meta also worked together recently to bring Xbox cloud gaming to the Quest.) Meta is also calling on Google to bring over the Google Play 2D app store to Meta Horizon OS. And, in an effort to bring more content to the Horizon ecosystem, software developed through the Quest App Lab will be featured in the Horizon Store. The company is also developing a new spatial framework to let mobile developers created mixed reality apps.

An anonymous reader quotes a report from Reuters: The Dutch privacy watchdog AP on Friday said it was recommending that government organizations should stop using Facebook as long as it is unclear what happens with personal data of users of the government's Facebook pages. "People that visit a government's page need to be able to trust that their personal and sensitive data is in safe hands," AP chairman Aleid Wolfsen said in a statement. Junior minister for digitalization Alexandra van Huffelen said Facebook parent company Meta had to make clear before the summer how it could take away the government's concerns on the safety of data. "Otherwise we will be forced to stop using Facebook, in line with this advice," she said.

Meta's Not Telling Where It Got Its AI Training Data

19 avril 2024 à 17:22
An anonymous reader shares a report: Today Meta unleashed its ChatGPT competitor, Meta AI, across its apps and as a standalone. The company boasts that it is running on its latest, greatest AI model, Llama 3, which was trained on "data of the highest quality"! A dataset seven times larger than Llama2! And includes 4 times more code! What is that training data? There the company is less loquacious. Meta said the 15 trillion tokens on which its trained came from "publicly available sources." Which sources? Meta told The Verge that it didn't include Meta user data, but didn't give much more in the way of specifics. It did mention that it includes AI-generated data, or synthetic data: "we used Llama 2 to generate the training data for the text-quality classifiers that are powering Llama 3." There are plenty of known issues with synthetic or AI-created data, foremost of which is that it can exacerbate existing issues with AI, because it's liable to spit out a more concentrated version of any garbage it is ingesting.

Meta AI et Llama 3 : tout comprendre à la stratégie de Facebook et Instagram pour détrôner ChatGPT

18 avril 2024 à 16:31

Meta AI, un chatbot uniquement disponible en anglais pour l'instant, devient encore plus performant grâce au nouveau modèle de langage Llama 3, dont les deux premières versions sont dévoilées aujourd'hui (avec 8 milliards ou 70 milliards de paramètres). L'objectif de Meta est de dépasser OpenAI et Google, grâce à ses 3 milliards d'utilisateurs dans le monde.

Meta Releases Llama 3 AI Models, Claiming Top Performance

Par : msmash
18 avril 2024 à 16:40
Meta debuted a new version of its powerful Llama AI model, its latest effort to keep pace with similar technology from companies like OpenAI, X and Google. The company describes Llama 3 8B and Llama 3 70B, containing 8 billion and 70 billion parameters respectively, as a "major leap" in performance compared to their predecessors. Meta claims that the Llama 3 models, trained on custom-built 24,000 GPU clusters, are among the best-performing generative AI models available for their respective parameter counts. The company supports this claim by citing the models' scores on popular AI benchmarks such as MMLU, ARC, and DROP, which attempt to measure knowledge, skill acquisition, and reasoning abilities. Despite the ongoing debate about the usefulness and validity of these benchmarks, they remain one of the few standardized methods for evaluating AI models. Llama 3 8B outperforms other open-source models like Mistral's Mistral 7B and Google's Gemma 7B on at least nine benchmarks, showcasing its potential in various domains such as biology, physics, chemistry, mathematics, and commonsense reasoning. TechCrunch adds: Now, Mistral 7B and Gemma 7B aren't exactly on the bleeding edge (Mistral 7B was released last September), and in a few of benchmarks Meta cites, Llama 3 8B scores only a few percentage points higher than either. But Meta also makes the claim that the larger-parameter-count Llama 3 model, Llama 3 70B, is competitive with flagship generative AI models including Gemini 1.5 Pro, the latest in Google's Gemini series.

Meta To Close Threads In Turkey To Comply With Injunction

16 avril 2024 à 00:50
Meta plans to "temporarily" shut down Threads in Turkey from April 29, in response to an interim injunction prohibiting data sharing with Instagram. TechCrunch reports: The Turkish Competition Authority (TCA), known as Rekabet Kurumu, noted on March 18 that its investigations found that Meta was abusing its dominant market position by combining the data of users who create Threads profiles with that of their Instagram account -- without giving users the choice to opt in. [...] In the buildup to April 29, everyone using Threads in Turkey will receive a notification about the impending closure, and they will be given a choice to either delete or deactivate their profile. The latter of these options means a user's profile can be resurrected when and if Threads is available in the country again. "We disagree with the interim order, we believe we are in compliance with all Turkish legal requirements, and we will appeal," Meta wrote in the blog post today. "The TCA's interim order leaves us with no choice but to temporarily shut down Threads in Turkiye. We will continue to constructively engage with the TCA and hope to bring Threads back to people in Turkiye as quickly as possible."

Meta Platforms To Launch Small Versions of Llama 3 Next Week

Par : msmash
9 avril 2024 à 16:41
Meta Platforms is planning to launch two small versions of its forthcoming Llama 3 large-language model next week, The Information has reported [non-paywalled link]. From the report: The models will serve as a precursor to the launch of the biggest version of Llama 3, expected this summer. Release of the two small models will likely help spark excitement for the forthcoming Llama 3, which will be coming out roughly a year after Llama 2 launched last July. It comes as several companies, including Google, Elon Musk's xAI and Mistral, have released open-source LLMs. Meta hopes Llama 3 will catch up with OpenAI's GPT-4, which can answer questions based on images users upload to the chatbot. The biggest version will be multimodal, which means it will be capable of understanding and generating both texts and images. In contrast, the two small models to be released next week won't be multimodal, the employee said.

Meta (Again) Denies Netflix Read Facebook Users' Private Messenger Messages

Par : EditorDavid
6 avril 2024 à 14:34
TechCrunch reports this week that Meta "is denying that it gave Netflix access to users' private messages..." The claim references a court filing that emerged as part of the discovery process in a class-action lawsuit over data privacy practices between a group of consumers and Facebook's parent, Meta. The document alleges that Netflix and Facebook had a "special relationship" and that Facebook even cut spending on original programming for its Facebook Watch video service so as not to compete with Netflix, a large Facebook advertiser. It also says that Netflix had access to Meta's "Inbox API" that offered the streamer "programmatic access to Facebook's user's private message inboxes...." Meta's communications director, Andy Stone, reposted the original X post on Tuesday with a statement disputing that Netflix had been given access to users' private messages. "Shockingly untrue," Stone wrote on X. "Meta didn't share people's private messages with Netflix. The agreement allowed people to message their friends on Facebook about what they were watching on Netflix, directly from the Netflix app. Such agreements are commonplace in the industry...." Beyond Stone's X post, Meta has not provided further comment. However, The New York Times had previously reported in 2018 that Netflix and Spotify could read users' private messages, according to documents it had obtained. Meta denied those claims at the time via a blog post titled "Facts About Facebook's Messaging Partnerships," where it explained that Netflix and Spotify had access to APIs that allowed consumers to message friends about what they were listening to on Spotify or watching on Netflix directly from those companies' respective apps. This required the companies to have "write access" to compose messages to friends, "read access" to allow users to read messages back from friends, and "delete access," which meant if you deleted a message from the third-party app, it would also delete the message from Facebook. "No third party was reading your private messages, or writing messages to your friends without your permission. Many news stories imply we were shipping over private messages to partners, which is not correct," the blog post stated. In any event, Messenger didn't implement default end-to-end encryption until December 2023, a practice that would have made these sorts of claims a non-starter, as it wouldn't have left room for doubt.

Meta Used Spyware to Access Its Users' Activities on Rival Platforms

Par : EditorDavid
31 mars 2024 à 18:40
New documents from a class action against Meta "reveal some of the specific ways it tackled rivals in recent years," reports the Observer. "One of them was using software made by a mobile data analytics company called Onavo in 2016 to access user activities on Snapchat, and eventually Amazon and YouTube, too." Facebook acquired Onavo in 2013 and shut it down in 2019 after a TechCrunch report revealed that the company was paying teenagers to use the software to collect user data. In 2020, two Facebook users filed a class action lawsuit in the U.S. District Court for the Northern District of California against Meta, then called Facebook, alleging the company engaged in anticompetitive practices and exploited user data. In 2023, the plaintiffs' attorney Brian J. Dunne submitted documents listing how Facebook used Onavo's software to spy on competitors, including Snapchat. According to the documents, made public this week, the Onavo team pitched and launched a project codenamed "Ghostbusters" — in reference to the Snapchat logo — where they developed "kits that can be installed on iOS or Android that intercept traffic for specific sub-domains," allowing them "to read what would otherwise be encrypted traffic so we can measure in-app usage." The documents also included a presentation from the Onavo team to Mark Zuckerberg showing that they had the ability to track "detailed in-app activity" by "parsing Snapchat analytics collected from incentivized participants in Onavo's program...." The technology was used to do the same to YouTube from 2017 to 2018 and Amazon in 2018, according to the documents. "The intended and actual result of this program was to harm competition, including Facebook's then-nascent Social Advertising competitor Snapchat," the document alleged.

Facebook Allegedly Killed Its Own Streaming Service To Help Sell Netflix Ads

Par : BeauHD
28 mars 2024 à 23:00
An anonymous reader quotes a report from Gizmodo: Do you remember Facebook Watch? Me neither. Mark Zuckerberg's short-lived streaming service never really got off the ground, but court filings unsealed in Meta's antitrust lawsuit claim "Watch" was kneecapped starting in 2018 to protect Zuckerberg's advertising relationship with Netflix CEO Reed Hastings. "For nearly a decade, Netflix and Facebook enjoyed a special relationship," said plaintiffs in filings (PDF) made public on Saturday. "It is no great mystery how this close partnership developed, and who was its steward: from 2011-2019, Netflix's then-CEO Hastings sat on Facebook's board and personally directed the companies' relationship" The filings detail Hastings' uncomfortably close relationship with Meta's upper management, including Zuckerberg and Sheryl Sandberg. During these years, Netflix was allegedly granted special access to Facebook users' private message inboxes, among other privileged analytics tools, in exchange for hundred-million-dollar advertising deals. This gave Facebook greater dominance in its all-important ad division, plaintiffs allege, so the company was fine to retreat from Netflix's streaming territory by shuttering Watch. In 2017, Facebook Watch began signing deals to populate its streaming service with original TV Shows from movie stars such as Bill Murray. A year later, the service attempted to license the popular '90s TV show Dawson's Creek. Facebook Watch had meaningful reach on the home screen of the social media platform, and an impressive budget as well. Facebook and Netflix appeared ready to butt heads in the streaming world, and the Netflix cofounder found himself in the middle as a Facebook board member. [...] Netflix was a large advertiser to Facebook, and plaintiffs allege Zuckerberg shuttered its promising Watch platform for the sake of the greater advertising business. Zuckerberg personally emailed the head of Facebook Watch in May of 2018, Fidji Simo, to tell her their budget was being slashed by $750 million, just two years after Watch's launch, according to court filings. The sudden pivot meant Facebook was now dismantling the streaming business it had spent the last two years growing. During this time period, Netflix increased its ad spend on Facebook to roughly $150 million a year and allegedly entered into agreements for increased data analytics. By early 2019, the ad spend increased to roughly $200 million a year. Hastings left Facebook's board later in 2019.

Meta Abandons Hacking Victims, Draining Law Enforcement Resources, Officials Say

6 mars 2024 à 20:27
41 state attorneys general penned a letter to Meta's top attorney on Wednesday saying complaints are skyrocketing across the United States about Facebook and Instagram user accounts being stolen, and declaring "immediate action" necessary to mitigate the rolling threat. Wired: The coalition of top law enforcement officials, spearheaded by New York attorney general Letitia James, says the "dramatic and persistent spike" in complaints concerning account takeovers amounts to a "substantial drain" on governmental resources, as many stolen accounts are also tied to financial crimes -- some of which allegedly profits Meta directly. "We have received a number of complaints of threat actors fraudulently charging thousands of dollars to stored credit cards," says the letter addressed to Meta's chief legal officer, Jennifer Newstead. "Furthermore, we have received reports of threat actors buying advertisements to run on Meta." "We refuse to operate as the customer service representatives of your company," the officials add. "Proper investment in response and mitigation is mandatory."

Meta Says It's Deleting All Oculus Accounts At the End of the Month

Par : BeauHD
2 mars 2024 à 01:25
Emma Roth reports via The Verge: If you still haven't migrated your Oculus account to a Meta one, you might want to do that soon. In an email sent to users, the company says it will delete Oculus accounts on March 29th, 2024, preventing you from reactivating or retrieving your apps, in-app purchases, store credits, and more. You'll lose your achievements, friends list, and any content created with your Oculus account if you don't migrate to a Meta account before then. Oculus accounts have been on the way out since 2020, when the company then known as Facebook started requiring new users to sign up with Facebook accounts instead. However, it added the ability to create a Meta account in 2022, offering an alternative to users who didn't want to link their Facebook account to their Quest headset. Meta stopped letting users log in to their Oculus accounts in January 2023. If you've got a Quest gathering dust in a drawer somewhere, now's your last chance to migrate your Oculus account to a Meta one. You can migrate your account by heading to this page and signing up for a Meta account with the same email you've used for Oculus. From there, you'll be able to access all of the same games, data, and other purchases saved to your Oculus account.

Meta Wants Llama 3 To Handle Contentious Questions as Google Grapples With Gemini Backlash

Par : msmash
28 février 2024 à 15:21
An anonymous reader shares a report (paywalled): As Google grapples with the backlash over the historically inaccurate responses on its Gemini chatbot, Meta Platforms is dealing with a related issue. As part of its work on the forthcoming version of its large language model, Llama 3, Meta is trying to overcome a problem perceived in Llama 2: Its answers to anything at all contentious aren't helpful. Safeguards added to Llama 2, which Meta released last July and which powers the artificial intelligence assistant in its apps, prevent the LLM from answering a broad range of questions deemed controversial. These guardrails have made Llama 2 appear too "safe" in the eyes of Meta's senior leadership, as well as among some researchers who worked on the model itself, according to people who work at Meta. [...] Meta's conservative approach with Llama 2 was designed to ward off any public relations disasters, said the people who work at Meta. But researchers are now trying to loosen up Llama 3 so it engages more with users when they ask about difficult topics, offering context rather than just shutting down tricky questions, said two of the people who work at Meta. The new version of the model will in theory be able to better distinguish when a word has multiple meanings. For example, Llama 3 might understand that a question about how to kill a vehicle's engine means asking how to shut it off rather than end its life. Meta also plans to appoint someone internally in the coming weeks to oversee tone and safety training as part of its efforts to make the model's responses more nuanced, said one of the people. The company plans to release Llama 3 in July, though the timeline could still change, they added.
