ChatGPT made up a product feature out of thin air, so this company created it

On Monday, sheet music platform Soundslice says it developed a new feature after discovering that ChatGPT was incorrectly telling users the service could import ASCII tablature—a text-based guitar notation format the company had never supported. The incident reportedly marks what might be the first case of a business building functionality in direct response to an AI model's confabulation.

Typically, Soundslice digitizes sheet music from photos or PDFs and syncs the notation with audio or video recordings, allowing musicians to see the music scroll by as they hear it played. The platform also includes tools for slowing down playback and practicing difficult passages.

Adrian Holovaty, co-founder of Soundslice, wrote in a blog post that the recent feature development process began as a complete mystery. A few months ago, Holovaty began noticing unusual activity in the company's error logs. Instead of typical sheet music uploads, users were submitting screenshots of ChatGPT conversations containing ASCII tablature—simple text representations of guitar music that look like strings with numbers indicating fret positions.

AI mania pushes Nvidia to record $4 trillion valuation

On Wednesday, Nvidia became the first company in history to reach $4 trillion market valuation as shares rose more than 2 percent, reports CNBC. The GPU maker's stock has climbed 22 percent since the start of 2025, continuing a trend driven by demand for AI hardware following ChatGPT's late 2022 launch.

The milestone marks the highest market cap ever recorded for a publicly traded company, surpassing Apple's previous record of $3.8 trillion set in December. Nvidia first crossed $2 trillion in February 2024 and reached $3 trillion just four months later in June. The $4 trillion valuation represents a market capitalization larger than the GDP of most countries.

As we explained in 2023, Nvidia's continued success has been intimately tied to growth in demand for hardware that runs AI models as capably and efficiently as possible. The company's data center GPUs excel at performing billions of matrix multiplications necessary to train and run neural networks due to their parallel architecture—hardware architectures that originated as video game graphics accelerators now power the generative AI boom.

After 27 years, engineer discovers how to display secret photo in Power Mac ROM

On Tuesday, software engineer Doug Brown published his discovery of how to trigger a long-known but previously inaccessible Easter egg in the Power Mac G3's ROM: a hidden photo of the development team that nobody could figure out how to display for 27 years. While Pierre Dandumont first documented the JPEG image itself in 2014, the method to view it on the computer remained a mystery until Brown's reverse engineering work revealed that users must format a RAM disk with the text "secret ROM image."

Brown stumbled upon the image while using a hex editor tool called Hex Fiend with Eric Harmon's Mac ROM template to explore the resources stored in the beige Power Mac G3's ROM. The ROM appeared in desktop, minitower, and all-in-one G3 models from 1997 through 1999.

"While I was browsing through the ROM, two things caught my eye," Brown wrote. He found both the HPOE resource containing the JPEG image of team members and a suspicious set of Pascal strings in the PowerPC-native SCSI Manager 4.3 code that included ".Edisk," "secret ROM image," and "The Team."

The résumé is dying, and AI is holding the smoking gun

Employers are drowning in AI-generated job applications, with LinkedIn now processing 11,000 submissions per minute—a 45 percent surge from last year, according to new data reported by The New York Times.

Due to AI, the traditional hiring process has become overwhelmed with automated noise. It's the résumé equivalent of AI slop—call it "hiring slop," perhaps—that currently haunts social media and the web with sensational pictures and misleading information. The flood of ChatGPT-crafted résumés and bot-submitted applications has created an arms race between job seekers and employers, with both sides deploying increasingly sophisticated AI tools in a bot-versus-bot standoff that is quickly spiraling out of control.

The Times illustrates the scale of the problem with the story of an HR consultant named Katie Tanner, who was so inundated with over 1,200 applications for a single remote role that she had to remove the post entirely and was still sorting through the applications three months later.

MIT student prints AI polymer masks to restore paintings in hours

MIT graduate student Alex Kachkine once spent nine months meticulously restoring a damaged baroque Italian painting, which left him plenty of time to wonder if technology could speed things up. Last week, MIT News announced his solution: a technique that uses AI-generated polymer films to physically restore damaged paintings in hours rather than months. The research appears in Nature.

Kachkine's method works by printing a transparent "mask" containing thousands of precisely color-matched regions that conservators can apply directly to an original artwork. Unlike traditional restoration, which permanently alters the painting, these masks can reportedly be removed whenever needed. So it's a reversible process that does not permanently change a painting.

"Because there's a digital record of what mask was used, in 100 years, the next time someone is working with this, they'll have an extremely clear understanding of what was done to the painting," Kachkine told MIT News. "And that's never really been possible in conservation before."

Scientists once hoarded pre-nuclear steel; now we’re hoarding pre-AI content

Former Cloudflare executive John Graham-Cumming recently announced that he launched a website, lowbackgroundsteel.ai, that treats pre-AI, human-created content like a precious commodity—a time capsule of organic creative expression from a time before machines joined the conversation. "The idea is to point to sources of text, images and video that were created prior to the explosion of AI-generated content," Graham-Cumming wrote on his blog last week. The reason? To preserve what made non-AI media uniquely human.

The archive name comes from a scientific phenomenon from the Cold War era. After nuclear weapons testing began in 1945, atmospheric radiation contaminated new steel production worldwide. For decades, scientists needing radiation-free metal for sensitive instruments had to salvage steel from pre-war shipwrecks. Scientists called this steel "low-background steel." Graham-Cumming sees a parallel with today's web, where AI-generated content increasingly mingles with human-created material and contaminates it.

With the advent of generative AI models like ChatGPT and Stable Diffusion in 2022, it has become far more difficult for researchers to ensure that media found on the Internet was created by humans without using AI tools. ChatGPT in particular triggered an avalanche of AI-generated text across the web, forcing at least one research project to shut down entirely.

Engineer creates first custom motherboard for 1990s PlayStation console

Last week, electronics engineer Lorentio Brodesco announced the completion of a mock-up for nsOne, reportedly the first custom PlayStation 1 motherboard created outside of Sony in the console's 30-year history. The fully functional board accepts original PlayStation 1 chips and fits directly into the original console case, marking a milestone in reverse-engineering for the classic console released in 1994.

Brodesco's motherboard isn't an emulator or FPGA-based re-creation—it's a genuine circuit board designed to work with authentic PlayStation 1 components, including the CPU, GPU, SPU, RAM, oscillators, and voltage regulators. The board represents over a year of reverse-engineering work that began in March 2024 when Brodesco discovered incomplete documentation while repairing a PlayStation 1.

"This isn't an emulator. It's not an FPGA. It's not a modern replica," Brodesco wrote in a Reddit post about the project. "It's a real motherboard, compatible with the original PS1 chips."

US air traffic control still runs on Windows 95 and floppy disks

On Wednesday, acting FAA Administrator Chris Rocheleau told the House Appropriations Committee that the Federal Aviation Administration plans to replace its aging air traffic control systems, which still rely on floppy disks and Windows 95 computers, Tom's Hardware reports. The agency has issued a Request For Information to gather proposals from companies willing to tackle the massive infrastructure overhaul.

"The whole idea is to replace the system. No more floppy disks or paper strips," Rocheleau said during the committee hearing. Transportation Secretary Sean Duffy called the project "the most important infrastructure project that we've had in this country for decades," describing it as a bipartisan priority.

Most air traffic control towers and facilities across the US currently operate with technology that seems frozen in the 20th century, although that isn't necessarily a bad thing—when it works. Some controllers currently use paper strips to track aircraft movements and transfer data between systems using floppy disks, while their computers run Microsoft's Windows 95 operating system, which launched in 1995.

Bill Atkinson, architect of the Mac’s graphical soul, dies at 74

On Thursday, pioneering computer engineer and Apple veteran William "Bill" Atkinson died of pancreatic cancer at his home in Portola Valley, California, surrounded by family. He was 74. "We regret to write that our beloved husband, father, and stepfather Bill Atkinson passed away," his family wrote on Facebook. "He was a remarkable person, and the world will be forever different because he lived in it."

As Apple employee No. 51, Atkinson transformed abstract computer science into intuitive visual experiences that millions would use daily: His QuickDraw graphics engine made the Macintosh interface possible; he introduced the wider world to bitmap editing with MacPaint; and HyperCard presaged hyperlinked elements of the World Wide Web by years.

Anthropic releases custom AI chatbot for classified spy work

On Thursday, Anthropic unveiled specialized AI models designed for US national security customers. The company released "Claude Gov" models that were built in response to direct feedback from government clients to handle operations such as strategic planning, intelligence analysis, and operational support. The custom models reportedly already serve US national security agencies, with access restricted to those working in classified environments.

The Claude Gov models differ from Anthropic's consumer and enterprise offerings, also called Claude, in several ways. They reportedly handle classified material, "refuse less" when engaging with classified information, and are customized to handle intelligence and defense documents. The models also feature what Anthropic calls "enhanced proficiency" in languages and dialects critical to national security operations.

Anthropic says the new models underwent the same "safety testing" as all Claude models. The company has been pursuing government contracts as it seeks reliable revenue sources, partnering with Palantir and Amazon Web Services in November to sell AI tools to defense customers.

“In 10 years, all bets are off”—Anthropic CEO opposes decadelong freeze on state AI laws

On Thursday, Anthropic CEO Dario Amodei argued against a proposed 10-year moratorium on state AI regulation in a New York Times opinion piece, calling the measure shortsighted and overbroad as Congress considers including it in President Trump's tax policy bill. Anthropic makes Claude, an AI assistant similar to ChatGPT.

Amodei warned that AI is advancing too fast for such a long freeze, predicting these systems "could change the world, fundamentally, within two years; in 10 years, all bets are off."

As we covered in May, the moratorium would prevent states from regulating AI for a decade. A bipartisan group of state attorneys general has opposed the measure, which would preempt AI laws and regulations recently passed in dozens of states.

Endangered classic Mac plastic color returns as 3D-printer filament

On Tuesday, classic computer collector Joe Strosnider announced the availability of a new 3D-printer filament that replicates the iconic "Platinum" color scheme used in classic Macintosh computers from the late 1980s through the 1990s. The PLA filament (PLA is short for polylactic acid) allows hobbyists to 3D-print nostalgic novelties, replacement parts, and accessories that match the original color of vintage Apple computers.

Hobbyists commonly feed this type of filament into commercial desktop 3D printers, which heat the plastic and extrude it in a computer-controlled way to fabricate new plastic parts.

The Platinum color, which Apple used in its desktop and portable computer lines starting with the Apple IIgs in 1986, has become synonymous with a distinctive era of classic Macintosh aesthetic. Over time, original Macintosh plastics have become brittle and discolored with age, so matching the "original" color can be a somewhat challenging and subjective experience.

Hidden AI instructions reveal how Anthropic controls Claude 4

On Sunday, independent AI researcher Simon Willison published a detailed analysis of Anthropic's newly released system prompts for Claude 4's Opus 4 and Sonnet 4 models, offering insights into how Anthropic controls the models' "behavior" through their outputs. Willison examined both the published prompts and leaked internal tool instructions to reveal what he calls "a sort of unofficial manual for how best to use these tools."

To understand what Willison is talking about, we'll need to explain what system prompts are. Large language models (LLMs) like the AI models that run Claude and ChatGPT process an input called a "prompt" and return an output that is the most likely continuation of that prompt. System prompts are instructions that AI companies feed to the models before each conversation to establish how they should respond.

Unlike the messages users see from the chatbot, system prompts typically remain hidden from the user and tell the model its identity, behavioral guidelines, and specific rules to follow. Each time a user sends a message, the AI model receives the full conversation history along with the system prompt, allowing it to maintain context while following its instructions.

New Claude 4 AI model refactored code for 7 hours straight

On Thursday, Anthropic released Claude Opus 4 and Claude Sonnet 4, marking the company's return to larger model releases after primarily focusing on mid-range Sonnet variants since June of last year. The new models represent what the company calls its most capable coding models yet, with Opus 4 designed for complex, long-running tasks that can operate autonomously for hours.

Alex Albert, Anthropic's head of Claude Relations, told Ars Technica that the company chose to revive the Opus line because of growing demand for agentic AI applications. "Across all the companies out there that are building things, there's a really large wave of these agentic applications springing up, and a very high demand and premium being placed on intelligence," Albert said. "I think Opus is going to fit that groove perfectly."

Before we go further, a brief refresher on Claude's three AI model "size" names (introduced in March 2024) is probably warranted. Haiku, Sonnet, and Opus offer a tradeoff between price (in the API), speed, and capability.

The empire strikes back with F-bombs: AI Darth Vader goes rogue with profanity, slurs

For a short period of time on Friday, Darth Vader could drop F-bombs in the video game Fortnite as part of a voice AI implementation gone wrong, reports GameSpot. Epic Games rapidly deployed a hotfix after players encountered the Sith Lord responding to their comments with profanity and strong language.

In Fortnite, the AI-voiced Vader appears as both a boss in battle royale mode and an interactive character. The official Star Wars website encourages players to "ask him all your pressing questions about the Force, the Galactic Empire… or you know, a good strat for the last Storm circle," adding that "the Sith Lord has opinions."

The F-bomb incident involved a Twitch streamer named Loserfruit, who triggered the forceful response when discussing food with the virtual Vader. The Dark Lord of the Sith responded by repeating her words "freaking" and "fucking" before adding, "Such vulgarity does not become you, Padme." The exchange spread virally across social media platforms on Friday.

OpenAI adds GPT-4.1 to ChatGPT amid complaints over confusing model lineup

On Wednesday, OpenAI announced that ChatGPT users now have access to GPT-4.1, an AI language model previously available only through the company's API since its launch one month ago. The update brings what OpenAI describes as improved coding and web development capabilities to paid ChatGPT subscribers, with wider enterprise rollout planned in the coming weeks.

Adding GPT-4.1 and 4.1 mini to ChatGPT adds to an already complex model selection that includes GPT-4o, various specialized GPT-4o versions, o1-pro, o3-mini, and o3-mini-high models. There are technically nine AI models available for ChatGPT Pro subscribers. Wharton professor Ethan Mollick recently publicly lampooned the awkward situation on social media.

As of May 14, 2025, ChatGPT Pro users have access to 8 different main AI models, plus Deep Research. As of May 14, 2025, ChatGPT Pro users have access to eight main AI models, plus Deep Research. Credit: Benj Edwards

Deciding which AI model to use can be daunting for AI novices. Reddit users and OpenAI forum members alike commonly voice confusion about the available options. "I do not understand the reason behind having multiple models available for use," wrote one Reddit user in March. "Why would anyone use anything but the best one?" Another Redditor said they were "a bit lost" with the many ChatGPT models available after switching back from using Anthropic Claude.

AI use damages professional reputation, study suggests

Using AI can be a double-edged sword, according to new research from Duke University. While generative AI tools may boost productivity for some, they might also secretly damage your professional reputation.

On Thursday, the Proceedings of the National Academy of Sciences (PNAS) published a study showing that employees who use AI tools like ChatGPT, Claude, and Gemini at work face negative judgments about their competence and motivation from colleagues and managers.

"Our findings reveal a dilemma for people considering adopting AI tools: Although AI can enhance productivity, its use carries social costs," write researchers Jessica A. Reif, Richard P. Larrick, and Jack B. Soll of Duke's Fuqua School of Business.

Fidji Simo joins OpenAI as new CEO of Applications

On Wednesday, OpenAI announced that Instacart CEO Fidji Simo will join the maker of ChatGPT as "CEO of Applications" later this year, according to a company blog post. Simo, who has served on the company's board since March 2024, will oversee business and operational teams while continuing to report directly to Altman in the newly created role. Altman will remain the primary CEO of OpenAI.

According to Reuters, Simo spent a decade at Meta, including a stint serving as the head of Facebook from 2019 to 2021. She also currently sits on the board of e-commerce services site Shopify.

The announcement came earlier than planned due to what Altman described as "a leak" that "accelerated our timeline." At OpenAI, Simo will manage what Altman called "traditional company functions" as the organization enters its "next phase of growth." The applications category at OpenAI includes products like ChatGPT, the popular AI assistant.

Trump admin to roll back Biden’s AI chip restrictions

On Wednesday, the Trump administration announced plans to rescind and replace a Biden-era rule regulating the export of high-end AI accelerator chips worldwide, Bloomberg and Reuters reported.

A Department of Commerce spokeswoman told Reuters that officials found the previous framework "overly complex, overly bureaucratic, and would stymie American innovation" and pledged to create "a much simpler rule that unleashes American innovation and ensures American AI dominance."

The Biden administration issued the Framework for Artificial Intelligence Diffusion in January during its final week in office. The regulation represented the last salvo of a four-year effort to control global access to so-called "advanced" AI chips (such as GPUs made by Nvidia), with a focus on restricting China's ability to obtain tech that could enhance its military capabilities.

OpenAI scraps controversial plan to become for-profit after mounting pressure

On Monday, ChatGPT-maker OpenAI announced it will remain under the control of its founding nonprofit board, scrapping its controversial plan to split off its commercial operations as a for-profit company after mounting pressure from critics.

In an official OpenAI blog post announcing the latest restructuring decision, CEO Sam Altman wrote: "We made the decision for the nonprofit to stay in control after hearing from civic leaders and having discussions with the offices of the Attorneys General of California and Delaware."

The move represents a significant shift in OpenAI's proposed restructuring. While the most recent previous version of the company's plan (which we covered in December) would have established OpenAI as a Public Benefit Corporation with the nonprofit merely holding shares and having limited influence, the revised approach keeps the nonprofit firmly in control of operations.
