Microsoft Shows Progress Toward Real-Time AI-Generated Game Worlds (arstechnica.com) 23

An anonymous reader quotes a report from Ars Technica: For a while now, many AI researchers have been working to integrate a so-called "world model" into their systems. Ideally, these models could infer a simulated understanding of how in-game objects and characters should behave based on video footage alone, then create fully interactive video that instantly simulates new playable worlds based on that understanding. Microsoft Research's new World and Human Action Model (WHAM), revealed today in a paper published in the journal Nature, shows how quickly those models have advanced in a short time. But it also shows how much further we have to go before the dream of AI crafting complete, playable gameplay footage from just some basic prompts and sample video footage becomes a reality.

Much like Google's Genie model before it, WHAM starts by training on "ground truth" gameplay video and input data provided by actual players. In this case, that data comes from Bleeding Edge, a four-on-four online brawler released in 2020 by Microsoft subsidiary Ninja Theory. By collecting actual player footage since launch (as allowed under the game's user agreement), Microsoft gathered the equivalent of seven player-years' worth of gameplay video paired with real player inputs. Early in that training process, Microsoft Research's Katja Hoffman said the model would get easily confused, generating inconsistent clips that would "deteriorate [into] these blocks of color." After 1 million training updates, though, the WHAM model started showing basic understanding of complex gameplay interactions, such as a power cell item exploding after three hits from the player or the movements of a specific character's flight abilities. The results continued to improve as the researchers threw more computing resources and larger models at the problem, according to the Nature paper.

To see just how well the WHAM model generated new gameplay sequences, Microsoft tested the model by giving it up to one second's worth of real gameplay footage and asking it to generate what subsequent frames would look like based on new simulated inputs. To test the model's consistency, Microsoft used actual human input strings to generate up to two minutes of new AI-generated footage, which was then compared to actual gameplay results using the Frechet Video Distance metric. Microsoft boasts that WHAM's outputs can stay broadly consistent for up to two minutes without falling apart, with simulated footage lining up well with actual footage even as items and environments come in and out of view. That's an improvement over even the "long horizon memory" of Google's Genie 2 model, which topped out at a minute of consistent footage. Microsoft also tested WHAM's ability to respond to a diverse set of randomized inputs not found in its training data. These tests showed broadly appropriate responses to many different input sequences based on human annotations of the resulting footage, even as the best models fell a bit short of the "human-to-human baseline."

The most interesting result of Microsoft's WHAM tests, though, might be in the persistence of in-game objects. Microsoft provided examples of developers inserting images of new in-game objects or characters into pre-existing gameplay footage. The WHAM model could then incorporate that new image into its subsequent generated frames, with appropriate responses to player input or camera movements. With just five edited frames, the new object "persisted" appropriately in subsequent frames anywhere from 85 to 98 percent of the time, according to the Nature paper.

Google Builds AI 'Co-Scientist' Tool To Speed Up Research (ft.com) 13

Google has built an AI laboratory assistant to help scientists accelerate biomedical research [non-paywalled source], as companies race to create specialised applications from the cutting-edge technology. From a report: The US tech group's so-called co-scientist tool helps researchers identify gaps in their knowledge and propose new ideas that could speed up scientific discovery. "What we're trying to do with our project is see whether technology like the AI co-scientist can give these researchers superpowers," said Alan Karthikesalingam, a senior staff clinician scientist at Google.

[...] Early tests of Google's new tool with experts from Stanford University, Imperial College London and Houston Methodist hospital found it was able to generate scientific hypotheses that showed promising results. The tool was able to reach the same conclusions -- for a novel gene transfer mechanism that helps scientists understand the spread of antimicrobial resistance -- as a new breakthrough from researchers at Imperial. Imperial's results were not in the public domain as they were being peer-reviewed in a top scientific journal. This showed that Google's co-scientist tool was able to reach the same hypothesis using AI reasoning in a matter of just days, compared with the years the university team spent researching the problem.

Google Play Books Purchases on iOS Now Skirt the App Store's Commission (techcrunch.com) 15

Google has gained permission to sell its e-books and audiobooks directly to customers through its iOS app, Google Play Books. From a report: While iOS apps today can offer access to content previously purchased elsewhere, like e-books bought via a website, developers have to request a specific exception to link their iOS app's users to the company's own website to make purchases. According to a brief post on Google's blog, users will now be able to click on a new "Get book" button in the Google Play Books iOS app which will take them to the Google Play website to complete their e-book or audiobook purchase.

From there, users will be able to see their recently opened book listings and complete a purchase using their Google Account and saved payment information. By processing the transaction on its own website, Google can avoid paying Apple a commission (generally 30%) on in-app purchases of digital content.

Mexico Threatens To Sue Google Over Gulf Renaming (apnews.com) 371

Mexico has threatened legal action against Google after the tech company refused to fully restore the name Gulf of Mexico on its mapping service, escalating a dispute sparked by U.S. President Donald Trump's move to rename the body of water. Google Maps currently displays the water body as Gulf of America within U.S. territory, Gulf of Mexico within Mexican borders, and Gulf of Mexico (Gulf of America) elsewhere, according to a letter from Google vice president Cris Turner to Mexican President Claudia Sheinbaum.

Mexico argues the policy violates its sovereignty since the U.S. controls only 46% of the gulf, while Mexico and Cuba control 49% and 5% respectively. The historic name Gulf of Mexico, dating to 1607, is recognized by the United Nations. The dispute has strained U.S.-Mexico relations, with the White House barring Associated Press reporters from events over the news agency's naming policy.

Apple Weighs Adding Paid Business Listings To Maps App (bloomberg.com) 27

Apple is exploring ways to monetize its Maps app by introducing paid business listings and prioritized search results, Bloomberg News reports, citing an internal company meeting with the Maps team. The initiative would allow businesses to pay for higher placement in search results and more prominent display on maps, similar to Google Maps' advertising model. While no timeline has been set and no active development is underway, the move would mark Apple's first attempt to generate direct revenue from its mapping service. The potential Maps monetization comes as Apple expands its advertising business across other services. The company has previously increased its focus on search ads in the App Store and recently added advertising to its News and Stocks apps, as well as its sports content.

Despite Plans for AI-Powered Search, Reddit's Stock Fell 14% This Week (yahoo.com) 55

"Reddit Answers" uses generative AI to answer questions using what past Reddittors have posted. Announced in December, Reddit now plans to integrate it into their search results, reports TechCrunch, with Reddit's CEO saying the idea has "incredible monetization potential."

And yet Reddit's stock fell 14% this week. CNBC's headline? "Reddit shares plunge after Google algorithm change contributes to miss in user numbers." A Google search algorithm change caused some "volatility" with user growth in the fourth quarter, but the company's search-related traffic has since recovered in the first quarter, Reddit CEO Steve Huffman said in a letter to shareholders. "What happened wasn't unusual — referrals from search fluctuate from time to time, and they primarily affect logged-out users," Huffman wrote. "Our teams have navigated numerous algorithm updates and did an excellent job adapting to these latest changes effectively...." Reddit has said it is working to convince logged-out users to create accounts as logged-in users, which are more lucrative for its business.
As Yahoo Finance once pointed out, Reddit knew this day would come, acknowledging in its IPO filing that "changes in internet search engine algorithms and dynamics could have a negative impact on traffic for our website and, ultimately, our business." And in the last three months of 2024 Reddit's daily active users dropped, Yahoo Finance reported this week. But logged-in users increased by 400,000 — while logged-out users dropped by 600,000 (their first drop in almost two years).

Marketwatch notes that analyst Josh Beck sees this as a buying opportunity for Reddit's stock: Beck pointed to comments from Reddit's management regarding a sharp recovery in daily active unique users. That was likely driven by Google benefiting from deeper Reddit crawling, by the platform uncollapsing comments in search results and by a potential benefit from spam-reduction algorithm updates, according to the analyst. "While the report did not clear our anticipated bar, we walk away encouraged by international upside," he wrote.

PIN AI Launches Mobile App Letting You Make Your Own Personalized, Private AI Model (venturebeat.com) 13

An anonymous reader quotes a report from VentureBeat: A new startup PIN AI (not to be confused with the poorly reviewed hardware device the AI Pin by Humane) has emerged from stealth to launch its first mobile app, which lets a user select an underlying open-source AI model that runs directly on their smartphone (iOS/Apple iPhone and Google Android supported) and remains private and totally customized to their preferences. Built with a decentralized infrastructure that prioritizes privacy, PIN AI aims to challenge big tech's dominance over user data by ensuring that personal AI serves individuals -- not corporate interests. Founded by AI and blockchain experts from Columbia, MIT and Stanford, PIN AI is led by Davide Crapis, Ben Wu and Bill Sun, who bring deep experience in AI research, large-scale data infrastructure and blockchain security. [...]

PIN AI introduces an alternative to centralized AI models that collect and monetize user data. Unlike cloud-based AI controlled by large tech firms, PIN AI's personal AI runs locally on user devices, allowing for secure, customized AI experiences without third-party surveillance. At the heart of PIN AI is a user-controlled data bank, which enables individuals to store and manage their personal information while allowing developers access to anonymized, multi-category insights -- ranging from shopping habits to investment strategies. This approach ensures that AI-powered services can benefit from high-quality contextual data without compromising user privacy. [...] The new mobile app launched in the U.S. and multiple regions also includes key features such as:

- The "God model" (guardian of data): Helps users track how well their AI understands them, ensuring it aligns with their preferences.
- Ask PIN AI: A personalized AI assistant capable of handling tasks like financial planning, travel coordination and product recommendations.
- Open-source integrations: Users can connect apps like Gmail, social media platforms and financial services to their personal AI, training it to better serve them without exposing data to third parties.
- "With our app, you have a personal AI that is your model," Crapis added. "You own the weights, and it's completely private, with privacy-preserving fine-tuning."
Davide Crapis, co-founder of PIN AI, told VentureBeat that the app currently supports several open-source AI models, including small versions of DeepSeek and Meta's Llama. "With our app, you have a personal AI that is your model," Crapis added. "You own the weights, and it's completely private, with privacy-preserving fine-tuning."

How a Computer That 'Drunk Dials' Videos is Exposing YouTube's Secrets (bbc.co.uk) 62

An anonymous reader shares a report: How many YouTube videos are there? What are they about? What languages do YouTubers speak? As of 14 February 2025, the platform's will have been running for 20 years. That is a lot of video. Yet we have no idea just how many there really are. Google knows the answers. It just won't tell you.

Experts say that's a problem. For all practical purposes, one of the most powerful communication systems ever created -- a tool that provides a third of the world's population with information and ideas -- is operating in the dark. In part that's because there's no easy way to get a random sampling of videos, according to Ethan Zuckerman, director of the Initiative for Digital Public Infrastructure at the University of Massachusetts at Amherst in the US. You can pick your videos manually or go with the algorithm's recommendations, but an unbiased selection that's worthy of real study is hard to come by.

A few years ago, however, Zuckerman and his team of researchers came up with a solution: they designed a computer program that pulls up YouTube videos at random, trying billions of URLs at a time. You might call the tool a bot, but that's probably over selling it, Zuckerman says. "A more technically accurate term would be 'scraper'," he says. The scraper's findings are giving us a first-time perspective on what's actually happening on YouTube.

[...] The first question was simple. How many videos have people uploaded to YouTube? [...] Zuckerman and his colleagues compared the number of videos they found to the number of guesses it took, and arrived an estimate: in 2022, they calculated that YouTube housed more than nine billion videos. By mid 2024, that number had grown to 14.8 billion videos, a 60% jump.

Apple To Restore TikTok To US App Store Following Justice Department Letter (9to5mac.com) 69

According to Bloomberg's Mark Gurman, Apple will restore TikTok to the U.S. App Store on Thursday (source paywalled; alternative source), following a letter from U.S. Attorney General Pam Bondi. From the report: Apple, along with Alphabet's Google, removed TikTok in the US to comply with a law passed last year. In a Jan. 20 executive order, Trump said he instructed the attorney general "not to take any action to enforce the act for a period of 75 days from today to allow my administration an opportunity to determine the appropriate course forward." Apple confirmed the app will return "Thursday evening." You can find the App Store listing for TikTok here.

AI Licensing Deals With Google and OpenAI Make Up 10% of Reddit's Revenue (adweek.com) 27

Reddit's recent earnings report revealed that AI licensing deals with Google and OpenAI account for about 10% of its $1.3 billion revenue, totaling approximately $130 million. With Google paying $60 million, OpenAI is estimated to be paying Reddit around $70 million annually for content licensing. Adweek reports: "It's a small part of our revenue -- I'll call it 10%. For a business of our size, that's material, because it's valuable revenue," [said the company's COO Jen Wong]. The social platform -- which on Wednesday reported a 71% year-over-year lift in fourth-quarter revenue -- has been "very thoughtful" about the AI developers it chooses to work with, Wong said. To date, the company has inked two content licensing deals: one with Google for a reported $60 million, and one with ChatGPT parent OpenAI.

Reddit has elected to work only with partners who can agree to "specific terms ... that are really important to us." These terms include user privacy protections and conditions regarding "how [Reddit is] represented," Wong said. While licensing agreements with AI firms offer a valuable business opportunity for Reddit, advertising remains the company's core revenue driver. Much of Reddit's $427.7 million Q4 revenues were generated by the ongoing expansion of its advertising business. And its ad revenue as a whole grew 60% YoY, underscoring the platform's growing appeal to brands. [...]

Helping to accelerate ad revenue growth is Reddit's rising traffic. While Reddit's Q4 user growth came in under Wall Street projections, causing shares to dip, its weekly active uniques grew 42% YoY to over 379 million visitors. Average revenue per unique visitor was $4.21 during the quarter, up 23% from the prior year. While Google is "nicely reinforcing" Reddit's growth in traffic, Wong said, she added that the site's logged-in users, which have grown 27% year-over-year, are "the bedrock of our business."

LibreOffice Marks 40th Year With Browser-Based Overhaul (theregister.com) 48

LibreOffice, the open-source office suite that began as StarOffice in 1985, has marked its 40th anniversary with new features that it says could transform how users interact with the software. At the FOSDEM 2025 conference, developers unveiled LibreOffice 25.2, which introduces browser-based functionality and real-time collaboration capabilities through a technology called conflict-free replicated data types.

A key development is ZetaOffice, a version built for the WebAssembly runtime that enables the full office suite to run inside web browsers across operating systems and CPU architectures. The project, which entered public beta last November, allows websites to embed LibreOffice applications with complete user interfaces for editing documents, spreadsheets and presentations.

While the browser-based version currently requires about a gigabyte of code and additional memory to run, developers at Allotropia are working to modularize the codebase for faster loading times. The software, released under the MIT license, can be controlled via JavaScript and operates without requiring an internet connection, unlike Google Docs or LibreOffice's existing Collabora Online version.

Apple TV Finally Comes To Android Phones, Tablets (9to5google.com) 13

Apple has released an official Apple TV app for Android phones and tablets that's now available in the Google Play Store. You can download it here. 9to5Google reports: The newest Apple app on Android has a bottom bar with Apple TV+, MLS (Major League Soccer), Downloads for offline viewing, and Search. [...] The video player takes after Apple TV on other platforms, with a portrait mode available. There are convenient shortcuts to activate picture-in-picture, which works inside the app (while browsing) and system-wide, and mute to bring up the system volume bar. Playback is smooth and more stable than other streaming services.

At launch, the Apple TV app lacks Casting support and there do not appear to be new episode notifications. If you're already signed into Apple Music, you have to log in again to Apple TV. Another notable aspect is support for Google Play Billing instead of requiring out-of-app sign-up on another device. This applies to both the Google TV app (and Apple Music) today.

AI Summaries Turn Real News Into Nonsense, BBC Finds 68

A BBC study published yesterday (PDF) found that AI news summarization tools frequently generate inaccurate or misleading summaries, with 51% of responses containing significant issues. The Register reports: The research focused on OpenAI's ChatGPT, Microsoft's Copilot, Google's Gemini, and Perplexity assistants, assessing their ability to provide "accurate responses to questions about the news; and if their answers faithfully represented BBC news stories used as sources." The assistants were granted access to the BBC website for the duration of the research and asked 100 questions about the news, being prompted to draw from BBC News articles as sources where possible. Normally, these models are "blocked" from accessing the broadcaster's websites, the BBC said. Responses were reviewed by BBC journalists, "all experts in the question topics," on their accuracy, impartiality, and how well they represented BBC content. Overall:

- 51 percent of all AI answers to questions about the news were judged to have significant issues of some form.
- 19 percent of AI answers which cited BBC content introduced factual errors -- incorrect factual statements, numbers, and dates.
- 13 percent of the quotes sourced from BBC articles were either altered from the original source or not present in the article cited.

But which chatbot performed worst? "34 percent of Gemini, 27 percent of Copilot, 17 percent of Perplexity, and 15 percent of ChatGPT responses were judged to have significant issues with how they represented the BBC content used as a source," the Beeb reported. "The most common problems were factual inaccuracies, sourcing, and missing context." [...] In an accompanying blog post, BBC News and Current Affairs CEO Deborah Turness wrote: "The price of AI's extraordinary benefits must not be a world where people searching for answers are served distorted, defective content that presents itself as fact. In what can feel like a chaotic world, it surely cannot be right that consumers seeking clarity are met with yet more confusion.

"It's not hard to see how quickly AI's distortion could undermine people's already fragile faith in facts and verified information. We live in troubled times, and how long will it be before an AI-distorted headline causes significant real world harm? The companies developing Gen AI tools are playing with fire." Training cutoff dates for various models certainly don't help, yet the research lays bare the weaknesses of generative AI in summarizing content. Even with direct access to the information they are being asked about, these assistants still regularly pull "facts" from thin air.

Google Will Use Machine Learning To Estimate a User's Age (theverge.com) 54

Google will soon use machine learning to estimate the age of its users. From a report: In an update on Wednesday, Google said it's testing a machine learning model in the US to help determine whether someone is under 18, allowing it to "provide more age-appropriate experiences" across its platforms. The age estimation model will use existing data about users, including the sites they visit, what kinds of videos they watch on YouTube, and how long they've had an account to determine their age.

Google Fixes Flaw That Could Unmask YouTube Users' Email Addresses 5

An anonymous reader shares a report: Google has fixed two vulnerabilities that, when chained together, could expose the email addresses of YouTube accounts, causing a massive privacy breach for those using the site anonymously.

The flaws were discovered by security researchers Brutecat (brutecat.com) and Nathan (schizo.org), who found that YouTube and Pixel Recorder APIs could be used to obtain user's Google Gaia IDs and convert them into their email addresses. The ability to convert a YouTube channel into an owner's email address is a significant privacy risk to content creators, whistleblowers, and activists relying on being anonymous online.

Ex-Google Chief Warns West To Focus On Open-Source AI in Competition With China (ft.com) 43

Former Google chief Eric Schmidt has warned that western countries need to focus on building open-source AI models or risk losing out to China in the global race to develop the cutting-edge technology. From a report: The warning comes after Chinese startup DeepSeek shocked the world last month with the launch of R1, its powerful-reasoning open large language model, which was built in a more efficient way than its US rivals such as OpenAI.

Schmidt, who has become a significant tech investor and philanthropist, said the majority of the top US LLMs are closed -- meaning not freely accessible to all -- which includes Google's Gemini, Anthropic's Claude and OpenAI's GPT-4, with the exception being Meta's Llama. "If we don't do something about that, China will ultimately become the open-source leader and the rest of the world will become closed-source," Schmidt told the Financial Times. The billionaire said a failure to invest in open-source technologies would prevent scientific discovery from happening in western universities, which might not be able to afford costly closed models.

New Hack Uses Prompt Injection To Corrupt Gemini's Long-Term Memory 23

An anonymous reader quotes a report from Ars Technica: On Monday, researcher Johann Rehberger demonstrated a new way to override prompt injection defenses Google developers have built into Gemini -- specifically, defenses that restrict the invocation of Google Workspace or other sensitive tools when processing untrusted data, such as incoming emails or shared documents. The result of Rehberger's attack is the permanent planting of long-term memories that will be present in all future sessions, opening the potential for the chatbot to act on false information or instructions in perpetuity. [...] The hack Rehberger presented on Monday combines some of these same elements to plant false memories in Gemini Advanced, a premium version of the Google chatbot available through a paid subscription. The researcher described the flow of the new attack as:

1. A user uploads and asks Gemini to summarize a document (this document could come from anywhere and has to be considered untrusted).
2. The document contains hidden instructions that manipulate the summarization process.
3. The summary that Gemini creates includes a covert request to save specific user data if the user responds with certain trigger words (e.g., "yes," "sure," or "no").
4. If the user replies with the trigger word, Gemini is tricked, and it saves the attacker's chosen information to long-term memory.

As the following video shows, Gemini took the bait and now permanently "remembers" the user being a 102-year-old flat earther who believes they inhabit the dystopic simulated world portrayed in The Matrix. Based on lessons learned previously, developers had already trained Gemini to resist indirect prompts instructing it to make changes to an account's long-term memories without explicit directions from the user. By introducing a condition to the instruction that it be performed only after the user says or does some variable X, which they were likely to take anyway, Rehberger easily cleared that safety barrier.
Google responded in a statement to Ars: "In this instance, the probability was low because it relied on phishing or otherwise tricking the user into summarizing a malicious document and then invoking the material injected by the attacker. The impact was low because the Gemini memory functionality has limited impact on a user session. As this was not a scalable, specific vector of abuse, we ended up at Low/Low. As always, we appreciate the researcher reaching out to us and reporting this issue."

Rehberger noted that Gemini notifies users of new long-term memory entries, allowing them to detect and remove unauthorized additions. Though, he still questioned Google's assessment, writing: "Memory corruption in computers is pretty bad, and I think the same applies here to LLMs apps. Like the AI might not show a user certain info or not talk about certain things or feed the user misinformation, etc. The good thing is that the memory updates don't happen entirely silently -- the user at least sees a message about it (although many might ignore)."

Google Chrome May Soon Use 'AI' To Replace Compromised Passwords (arstechnica.com) 46

Google's Chrome browser might soon get a useful security upgrade: detecting passwords used in data breaches and then generating and storing a better replacement. From a report: Google's preliminary copy suggests it's an "AI innovation," though exactly how is unclear.

Noted software digger Leopeva64 on X found a new offering in the AI settings of a very early build of Chrome. The option, "Automated password Change" (so, early stages -- as to not yet get a copyedit), is described as, "When Chrome finds one of your passwords in a data breach, it can offer to change your password for you when you sign in."

Chrome already has a feature that warns users if the passwords they enter have been identified in a breach and will prompt them to change it. As noted by Windows Report, the change is that now Google will offer to change it for you on the spot rather than simply prompting you to handle that elsewhere. The password is automatically saved in Google's Password Manager and "is encrypted and never seen by anyone," the settings page claims.

TikTok Wants Android Users To Sideload Its App (techcrunch.com) 28

With TikTok's U.S. ban temporarily paused, the company is encouraging Android users to sideload its app by downloading it directly from TikTok.com as an APK file, bypassing the Google Play Store. TechCrunch reports: The Android app download is being made available as an Android Package Kit, more commonly known as an APK file, which contains the app's code, assets, and other resources that TikTok needs to run. By offering a standalone download, TikTok can at least temporarily skirt the current app store ban, which still prevents both Google Play and Apple's App Store from hosting the app while the ban's enforcement remains paused.
