OpenAI Rolls Out GPT-4.5 (openai.com) 23

OpenAI released an early version of its new AI model GPT-4.5 to select users on Thursday, following development challenges that delayed the project last year. The Microsoft-backed startup said the new model responds better to subtle cues in written prompts and excels at chatting, writing and coding. OpenAI expects it will produce fewer fabricated responses than previous versions.

Initially available as a "research preview," access is limited to software developers and users who pay $200 monthly for ChatGPT Pro subscriptions. The company plans to gather feedback before wider distribution. According to OpenAI's blog post, GPT-4.5 will be the company's last model that doesn't use additional computing power to analyze queries before responding. Future releases will incorporate the reasoning approach already used in its newer models like o1 and o3.

Microsoft Urges Trump To Overhaul Curbs on AI Chip Exports (wsj.com) 30

Microsoft is pushing the Trump administration to loosen and simplify a new system that would restrict the sales of cutting-edge U.S. artificial-intelligence chips to much of the world. From a report: In a blog post that is scheduled to be released Thursday, Microsoft will call for Trump's team to ease the limits on chips that can be used in data centers for training AI models so they no longer apply to a group of U.S. allies including India, Switzerland and Israel [non-paywalled source], company officials said. Those countries are in the second tier of a three-tier system that underpins the export controls.

Microsoft says the unintended consequence of that proposed system would be that allies facing limited U.S. chip supply would turn to China to get the tech infrastructure they need. China is using the proposed rule to argue to other countries that it would be a better long-term partner for AI infrastructure than the U.S., Microsoft President Brad Smith said in an interview. "Their message is these countries can't rely on the U.S., but China is willing to provide what they need," he said. "That is not good for American business or American foreign policy."

Amazon Uses Quantum 'Cat States' With Error Correction (arstechnica.com) 11

An anonymous reader quotes a report from Ars Technica: Following up on Microsoft's announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two different types of qubit hardware to improve the stability of the quantum information they hold. The idea is that one type of qubit is resistant to errors, while the second can be used for implementing an error-correction code that catches the problems that do happen. While there have been more effective demonstrations of error correction in the past, a number of companies are betting that Amazon's general approach is the best route to getting logical qubits that are capable of complex algorithms. So, in that sense, it's an important proof of principle. Amazon's quantum computing approach combines cat qubits for data storage and transmons for error correction.

Cat qubits are quantum bits that distribute their superposition state across multiple photons in a resonator, making them highly resistant to bit flip errors. Transmons are superconducting qubits that help detect and correct phase flip errors by enabling weak measurements without destroying the quantum state. Meanwhile, a phase flip is a quantum error that alters the relative phase of a qubit's superposition state without changing its probability distribution. Unlike a bit flip, which swaps a qubit's state probabilities, a phase flip changes how the quantum states interfere, potentially disrupting quantum computations.

By alternating cat qubits with transmons, Amazon reduces the number of hardware qubits needed for error correction. Their tests show that increasing qubits lowers the error rate, proving the system's effectiveness. However, rare bit flips still cause entire logical qubits to fail, and transmons remain prone to both bit and phase flips. If you're still entangled in this story without decohering into pure quantum chaos, kudos to you!

Satya Nadella Argues AI's True Value Will Come When It Finds Killer App Akin To Email or Excel 95

Microsoft CEO Satya Nadella argues that AI's success should be measured by its impact on economic growth rather than achieving artificial general intelligence (AGI), emphasizing that true progress will come when AI finds a transformative application akin to email or Excel. The Register reports: "Us self-claiming some AGI milestone, that's just nonsensical benchmark hacking," the chief executive said during an appearance on podcaster Dwarkesh Patel's YouTube show this month. Nadella thinks a better benchmark for AI's success should be its ability to boost a country's gross domestic product. "When we say: 'Oh, this is like the industrial revolution,' let's have that industrial revolution type of growth. That means to me, 10 percent, seven percent for the developed world. Inflation adjusted, growing at five percent, that's the real marker."

Nadella suggested that growth hasn't eventuated because it's going to take time before folks understand how to use AI effectively, assuming they find a use for it -- just as it took some years for the personal computer to find its feet. "Just imagine how a multinational corporation like us did forecasts pre-PC, and email, and spreadsheets. Faxes went around, somebody then got those faxes and then did an inter-office memo that then went around, and people entered numbers, and then ultimately a forecast came out maybe just in time for the next quarter," Nadella explained. "Then somebody said: 'Hey, I'm just going to take an Excel spreadsheet, put it in an email, send it around, people will go edit it, and I'll have a forecast.' The entire forecasting business process changed because the work artifact and the workflow changed. That is what needs to happen with AI being introduced into knowledge work," the CEO said. [...]

"Don't conflate knowledge worker with knowledge work," he said. "The knowledge work of today could probably be automated, [but] who said my life's goal is to triage my email?" Instead, he argues AI agents will allow workers to focus on higher-value tasks. Whether this is actually how it'll play out, or whether enterprises will take this as an opportunity to reduce costs by cutting staff remains to be seen. ... "Today, you cannot deploy these intelligences unless and until there's someone indemnifying it as a human," he said.

Microsoft Trims More CPUs From Windows 11 Compatibility List (theregister.com) 95

Microsoft has updated its CPU compatibility list for Windows 11 24H2, excluding pre-11th-generation Intel processors for OEMs building new PCs. The Register reports: Windows 11 24H2 has been available to customers for months, yet Microsoft felt compelled in its February update to confirm that builders, specifically, must use Intel's 11th-generation or later silicon when building brand new PCs to run its most recent OS iteration. "These processors meet the design principles around security, reliability, and the minimum system requirements for Windows 11," Microsoft says.

Intel's 11th-generation chips arrived in 2020 and were discontinued last year. It would be surprising, if not unheard of, for OEMs to build machines with unsupported chips. Intel has already transitioned many pre-11th generation chips to "a legacy software support model," so Microsoft's decision to omit the chips from the OEM list is understandable. However, this could be seen as a creeping problem. Chips made earlier than that were present very recently, in the list of supported Intel processors for Windows 11 22H2 and 23H2.

This new OEM list may add to worries of some users looking at the general hardware compatibility specs for Windows 11 and wondering if the latest information means that even the slightly newer hardware in their org's fleet will soon no longer meet the requirements of Microsoft's flagship operating system. It's a good question, and the answer -- currently -- appears to be that those "old" CPUs are still suitable. Microsoft has a list of hardware compatibility requirements that customers can check, and they have not changed much since the outcry when they were first published.

Microsoft Quietly Launches Ad-Supported Version of Office Apps for Windows (windowscentral.com) 75

Microsoft has quietly launched a new version of Microsoft Office for Windows that can be used to edit documents for free, no Microsoft 365 subscription or Office license key required. From a report: This free version of Office is based on the full desktop apps, but has most features locked behind the Microsoft 365 subscription. The free version of Office for Windows includes ads that are permanently on screen when within a document in Word, PowerPoint, and Excel. Additionally, this new free version of Office also only allows you to save files to OneDrive, meaning no support for editing local files. To access the free version of Office, just skip the prompt to sign-in when you first run an Office app. From there, you will be given the choice to continue to use Office for free in exchange for ads and limited features. In this mode, you can open, view, and even edit documents, just like you can with the web version of Office.

AI Reshapes Corporate Workforce as Companies Halt Traditional Hiring 119

Major corporations are reshaping their workforces around AI with Salesforce announcing it will not hire software engineers in 2025 and other companies laying off thousands while shifting focus to AI-specific roles. Duolingo has laid off thousands after implementing ChatGPT-4, UPS cut 4,000 jobs in its largest layoff in 116 years, and IBM paused hiring for back-office and HR positions that AI can now handle.

Amazon is redirecting staff from Alexa to AI areas, while Intuit is laying off 10% of its non-AI workforce. Cisco plans to cut 7% of employees in its second round of job cuts this year as it prioritizes AI and cybersecurity. Salesforce reports its AI platform is boosting software engineering productivity by 30%. SAP is restructuring 8,000 positions to focus on AI-driven business areas. The trend extends globally, with Microsoft relocating thousands during an "exodus" from China, while entry-level jobs on Wall Street are becoming obsolete.

A study found that 3 out of 10 companies replaced workers with AI last year, with over one-third of firms using AI likely to automate more roles in 2025. Job listings at large privately-held AI companies have dropped 14.2% over six months, JP Morgan wrote in a note seen by Slashdot. The transformation is creating new opportunities, with rising demand for AI skills in job postings. A survey of more than 1,200 users found nearly two-thirds of young professionals use AI tools at work, with 93% not worried about job threats, as business leaders view Generation Z's digital skills as beneficial for leveraging AI.

Microsoft Dropped Some AI Data Center Leases, TD Cowen Says (yahoo.com) 10

Microsoft has canceled some leases for US data center capacity, according to TD Cowen, raising broader concerns over whether it's securing more AI computing capacity than it needs in the long term. From a report: OpenAI's biggest backer has voided leases in the US totaling "a couple of hundred megawatts" of capacity -- the equivalent of roughly two data centers -- canceling agreements with at least a couple of private operators, the US brokerage wrote Friday, citing "channel checks" or inquiries with supply chain providers. TD Cowen said its checks also suggest Microsoft has pulled back on converting so-called statements of qualifications, agreements that usually lead to formal leases.

Microsoft in a statement on Monday reiterated its spending target for the fiscal year ending June, but declined to comment on TD Cowen's note. Exactly why Microsoft may be pulling some leases is unclear. TD Cowen posited in a second report on Monday that OpenAI is shifting workloads from Microsoft to Oracle as part of a relatively new partnership. The tech giant is also among the largest owners and operators of data centers in its own right and is spending billions of dollars on its own capacity. TD Cowen separately suggested that Microsoft may be reallocating some of that in-house investment to the US from abroad.

Meet the Journalists Training AI Models for Meta and OpenAI (niemanlab.org) 18

After completing a journalism graduate degree, Carla McCanna took a job "training AI models to optimize accuracy and efficiency," according an article by Nieman Journalism Lab: Staff jobs are scarce... and the competition for them is daunting. (In 2024, the already beleaguered U.S. news industry cut nearly 5,000 jobs, up 59% from the previous year, according to an annual report from Challenger, Gray & Christmas....) For the past couple months, McCanna has been working close to full-time for [AI training data company] Outlier, picking up projects on its gig platform at about $35 per hour. Data work has quickly become her primary source of income and a hustle she's recommended [to her journalism program classmates]. "A lot of us are still looking for jobs. Three times I told someone what I do, and they're like, please send it to me," she said. "It's hard right now, and a lot of my colleagues are saying the same thing."

McCanna is just one of many journalists who has been courted by Outlier to take on part-time, remote data work over the past year... Several of them told me they have taken on Outlier projects to supplement their income or replace their work in journalism entirely, because of dwindling staff jobs or freelance assignments drying up. Some are early-career journalists like McCanna, but others are reporters with over a decade of experience. One thing they all had in common? Before last year they'd never heard of Outlier or even knew that this type of work existed.

Launched back in 2023, Outlier is a platform owned and managed by Scale AI, a San Francisco-based data annotation company valued at $13.8 billion. It counts among its customers the world's largest AI companies, including OpenAI, Meta, and Microsoft. Outlier, and similar platforms like CrowdGen and Remotasks, use networks of remote human workers to improve the AI models of their clients. Workers are paid by the hour for tasks like labeling training data, drafting test prompts, and grading the factual accuracy and grammar of outputs. Often their work is fed back into an AI model to improve its performance, through a process called reinforcement learning with human feedback (RLHF). This human feedback loop has been core to building models like OpenAI's GPT and Meta's Llama.

Aside from direct recruitment messages, I also found dozens of recent public job postings that underscore this growing trend of hiring journalists for data work... Rather than training a replacement, McCanna sees her data work as an asset, growing her knowledge of AI tools as they continue to embed in the workplace. "Actually doing this work you realize AI models still need us ... I think it's going to be a really, really long time until they can truly write like humans."

Is the AI Boom Leading to More Natural Gas-Powered Utilities? (msn.com) 41

New power plants burning natural gas are being built all across America, reports the Washington Post, calling it a gas boom "driven in large part by AI."

They blame tech companies like Microsoft and Meta — which "looked to gas amid a shortage of adequate new clean energy" — while noting that those companies "say they plan to offset their development of natural gas capacity with equal investments in clean energy like solar and wind." [E]ven coal is making a comeback. But the biggest push is for gas, with more than 220 plants in various stages of development nationwide. They are often pitched as a bridge until more clean power is available, sometimes with promises the plants will eventually be equipped with nascent technology that traps greenhouse gas emissions. But the timeline for installing such "carbon capture" is vague. "These companies are building these massive new gas plants that are going to be there for 30 to 50 years," said Bill Weihl, a former director of sustainability at Facebook and founder of the nonprofit ClimateVoice. "That's not a bridge. It is a giant bomb in our carbon budget...."

Public filings from some of the big tech companies driving this development show their greenhouse gas emissions are soaring... "The last few years have revealed that a global energy transition is more complex and less linear than anticipated," Microsoft's board wrote in urging rejection of a December shareholder resolution demanding the company confront the climate risks of AI. "While urgency builds for decarbonization, so does the demand for energy."

Shareholders rejected the resolution. Microsoft is battling with environmental groups over its plans to build a multibillion-dollar data center in Mount Pleasant, Wisconsin, powered with electricity from natural gas. Their petition warns Microsoft's project "will push our state's climate goals out of reach, locking us into 30 more years of fossil fuels." The company said in a statement that it remains committed to erasing its emissions by adding substantial clean power to regional power grids. "By the end of 2025 we expect to meet our goal of adding new sources of carbon-free electricity to the grid equal to 100 percent of the electricity used by our datacenters," the statement said.

Meta says it is doing the same in Louisiana [where it's building a new 4-million-square-foot data center] and is "committed to matching our electricity use with 100 percent clean and renewable energy."

The article includes two revealing quotes:
  • "It is like everyone just gave up," said Aaron Zubaty, CEO of Eolian, a large clean energy developer that works with data centers.
  • American Petroleum Institute President Mike Sommers (who represents the oil and gas industry in Washington), said "The words that have replaced 'energy transition' are 'AI' and 'data centers'. We're transitioning from the energy transition to the energy reality ... We're going to need a lot more oil and gas."

Glitches for Windows 11 Update Include Breaking File Explorer (zdnet.com) 57

Five days ago on Patch Tuesday, Microsoft released patch KB5051987 for Windows 11 version 24H2, writes the XDA Developers site.

But "As reported by Windows Latest and various communities like Reddit and Microsoft's help forum, many users have encountered a major issue..."

Some have reported that, in addition to File Explorer failing to launch, they're unable to open folders from the desktop, save Office files, or even download files. Clicking on a folder icon may display its subfolders, but the contents within remain inaccessible... Some users on Microsoft's help forum and Reddit have also reported that the KB5051987 patch fails to install entirely. The update gets stuck at a certain percentage for hours before eventually displaying an error code. While these are among the most widely reported issues, others have surfaced as well, including problems with Taskbar preview animations, the camera, and more.
"Microsoft keeps running into brick walls with the 2024 version of Windows 11," writes ZDNet. "Each new update designed to fix the outstanding bugs ends up introducing other problems..." Among the glitches resolved were ones that affected digital audio converters, USB audio drivers, USB cameras, and passkeys. The update also patched several security vulnerabilities, including some that were deemed critical....

Other glitches that may pop up include a stuttering mouse, an undetectable camera, .NET apps that cannot be installed inside the Windows Sandbox, and the Taskbar's new preview animation that does not work properly. You may also encounter other roadblocks. One person in the Windows Feedback Hub said that after installing the update, the battery life shows only 2.5 hours versus 6 hours previously. Another person found that the clipboard history no longer copies items from Microsoft Word...

Each annual Windows update can suffer from bugs, especially after being rolled out to millions of users. However, Windows 11 24H2 has been more problematic than usual. Since its official launch last October, the 2024 version has carried with it a host of known issues, many of which still haven't been resolved.

Encrypted Messages Are Being Targeted, Google Security Group Warns (computerweekly.com) 20

Google's Threat Intelligence Group notes "the growing threat to secure messaging applications." While specifically acknowledging "wide ranging efforts to compromise Signal accounts," they add that the threat "also extends to other popular messaging applications such as WhatsApp and Telegram, which are also being actively targeted by Russian-aligned threat groups using similar techniques.

"In anticipation of a wider adoption of similar tradecraft by other threat actors, we are issuing a public warning regarding the tactics and methods used to date to help build public awareness and help communities better safeguard themselves from similar threats."

Computer Weekly reports: Analysts predict it is only a matter of time before Russia starts deploying hacking techniques against non-military Signal users and users of other encrypted messaging services, including WhatsApp and Telegram. Dan Black, principal analyst at Google Threat Intelligence Group, said he would be "absolutely shocked" if he did not see attacks against Signal expand beyond the war in Ukraine and to other encrypted messaging platforms...

Russia-backed hackers are attempting to compromise Signal's "linked devices" capability, which allows Signal users to link their messaging account to multiple devices, including phones and laptops, using a quick response (QR) code. Google threat analysts report that Russia-linked threat actors have developed malicious QR codes that, when scanned, will give the threat actor real-time access to the victim's messages without having to compromise the victim's phone or computer. In one case, according to Black, a compromised Signal account led Russia to launch an artillery strike against a Ukrainian army brigade, resulting in a number of casualties... Google also warned that multiple threat actors have been observed using exploits to steal Signal database files from compromised Android and Windows devices.

The article notes that the attacks "are difficult to detect and when successful there is a high risk that compromised Signal accounts can go unnoticed for a long time." And it adds that "The warning follows disclosures that Russian intelligence created a spoof website for the Davos World Economic Forum in January 2025 to surreptitiously attempt to gain access to WhatsApp accounts used by Ukrainian government officials, diplomats and a former investigative journalist at Bellingcat."

Google's Threat Intelligence Group notes there's a variety of attack methods, though the "linked devices" technique is the most widely used. "We are grateful to the team at Signal for their close partnership in investigating this activity," Google's group says in their blog post, adding that "the latest Signal releases on Android and iOS contain hardened features designed to help protect against similar phishing campaigns in the future. Update to the latest version to enable these features."

Game Developers Revolt Against Microsoft's New AI Gaming Tool (wired.com) 109

Microsoft's newly announced Muse AI model for game development has triggered immediate backlash from industry professionals. "Fuck this shit," responded David Goldfarb, founder of The Outsiders, arguing that such AI tools primarily serve to "reduce capital expenditure" while devaluing developers' collective artistic contributions.

Multiple developers told Wired that the tool is aimed at shareholders rather than actual developers. "Nobody will want this. They don't CARE that nobody will want this," one AAA developer said, noting that internal criticism remains muted due to job security concerns amid industry-wide layoffs.

The resistance comes as developers increasingly view AI initiatives as threats to job security rather than helpful tools. One anonymous developer called it "gross" that they needed to remain unnamed while criticizing Muse, as their studio still depends on potential Game Pass deals with Microsoft. Even in prototyping, where Microsoft sees AI potential, Creative Assembly's Marc Burrage warns that automated shortcuts could undermine crucial learning experiences in game development.

Scientists Question Microsoft's Quantum Computing Claims (msn.com) 21

Microsoft's announcement of a breakthrough in quantum computing faces skepticism from physicists, who say evidence supporting the company's claims remains insufficient.

The tech giant reported creating Majorana particles - a development it says could revolutionize quantum computing - but the accompanying peer-reviewed paper in Nature does not conclusively demonstrate this achievement, according to multiple quantum physics experts who reviewed the research.

Microsoft's corporate vice president for quantum hardware, Chetan Nayak, acknowledged the Nature paper wasn't meant to prove the particles' existence, though he claimed measurements suggested "95% likelihood" of topological activity. The company plans to publish additional findings.

The announcement has drawn particular scrutiny given the field's history of retracted claims. Two previous Nature papers on similar discoveries were withdrawn in 2017 and 2018, while a 2020 paper in Science involving Microsoft researchers remains under review. "This is where you cross over from the realm of science to advertising," said Jay Sau, a theoretical physicist at the University of Maryland who sometimes consults for Microsoft but wasn't involved in the current research.

OpenAI Plans To Shift Compute Needs From Microsoft To SoftBank (techcrunch.com) 9

According to The Information (paywalled), OpenAI plans to shift most of its computing power from Microsoft to SoftBank-backed Stargate by 2030. TechCrunch reports: That represents a major shift away from Microsoft, OpenAI's biggest shareholder, who fulfills most of the startup's power needs today. The change won't happen overnight. OpenAI still plans to increase its spending on Microsoft-owned data centers in the next few years.

During that time, OpenAI's overall costs are set to grow dramatically. The Information reports that OpenAI projects to burn $20 billion in cash during 2027, far more than the $5 billion it reportedly burned through in 2024. By 2030, OpenAI reportedly forecasts that its costs around running AI models, also known as inference, will outpace what the startup spends on training AI models.

AI Is Prompting an Evolution, Not Extinction, for Coders (thestar.com.my) 73

AI coding assistants are reshaping software development, but they're unlikely to replace human programmers entirely, according to industry experts and developers. GitHub CEO Thomas Dohmke projects AI could soon generate 80-90% of corporate code, transforming developers into "conductors of an AI-empowered orchestra" who guide and direct these systems.

Current AI coding tools, including Microsoft's GitHub Copilot, are delivering 10-30% productivity gains in business environments. At KPMG, developers report saving 4.5 hours weekly using Copilot, while venture investment in AI coding assistants tripled to $1.6 billion in 2024. The tools are particularly effective at automating routine tasks like documentation generation and legacy code translation, according to KPMG AI expert Swami Chandrasekaran.

They're also accelerating onboarding for new team members. Demand for junior developers remains soft, however, though analysts say it's premature to attribute this directly to AI adoption. Training programs like Per Scholas are already adapting, incorporating AI fundamentals alongside traditional programming basics to prepare developers for an increasingly AI-augmented workplace.

Malaysia is Betting on Data Centers To Boost Its Economy (apnews.com) 11

Malaysia is aggressively expanding its data center capacity, positioning itself as Southeast Asia's fastest-growing market with planned investments exceeding $31 billion in the first 10 months of 2024, triple the amount from 2023.

The country's southern Johor province is set to host at least 1.6 gigawatts of data center capacity, up from nearly zero in 2019. Twenty-two mostly foreign data centers already occupy 21 hectares, with more under construction. The push comes as neighboring Singapore paused new data center construction in 2019 due to resource constraints.

Some experts are warning the expansion could strain Malaysia's power and water resources, with data center power demand potentially reaching 5 gigawatts by 2035 - more than half the country's current renewable capacity. The facilities, operated by companies including Microsoft, Equinix and China's GDS Holdings, primarily service East Asia, China and Europe rather than domestic users.

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.

Microsoft Reveals Its First Quantum Computing Chip, the Majorana 1 (cnbc.com) 31

After two decades of quantum computing research, Microsoft has unveiled its first quantum chip: the Majorana 1. CNBC reports: Microsoft's quantum chip employs eight topological qubits using indium arsenide, which is a semiconductor, and aluminum, which is a superconductor. A new paper in the journal Nature describes the chip in detail. Microsoft won't be allowing clients to use its Majorana 1 chip through the company's Azure public cloud, as it plans to do with its custom artificial intelligence chip, Maia 100. Instead, Majorana 1 is a step toward a goal of a million qubits on a chip, following extensive physics research.

Rather than rely on Taiwan Semiconductor or another company for fabrication, Microsoft is manufacturing the components of Majorana 1 itself in the U.S. That's possible because the work is unfolding at a small scale. "We want to get to a few hundred qubits before we start talking about commercial reliability," Jason Zander, a Microsoft executive vice president, told CNBC. In the meantime, the company will engage with national laboratories and universities on research using Majorana 1.
