Researchers from OpenAI, Anthropic, Meta, and Google issue joint AI safety warning - here's why

Andriy Onufriyenko / Getty Images Over the last year, chain of thought (CoT) -- an AI model's ability to articulate its approach to a query in natural language -- has become an impressive development in generative AI, especially in agentic systems. Now, several researchers agree it may also be critical to AI safety efforts. On Tuesday, researchers from competing companies including OpenAI, Anthropic, Meta, and Google DeepMind, as well as institutions like the Center for AI Safety, Apollo Resea

Adobe Firefly can now generate sound effects from your audio cues

Since rolling out the redesign of its Firefly app in April, Adobe has been releasing major updates for the generative AI hub at a near monthly clip. Today, the company is introducing a handful of new features to assist those who use Firefly's video capabilities. To start, Adobe is making it easier to add sound effects to AI-generated clips. Right now, the majority of video models create footage without any accompanying audio. Adobe is addressing this with a nifty little feature that allows user

Delta Set to Expand AI-Powered Dynamic Ticket Pricing by the End of 2025

Last year, Delta Air Lines announced it was testing out dynamic pricing on some flights using tools built by the tech company Fetcherr. And while the test was initially limited, executives from the company announced that 3% of flights now use AI pricing, and they hope to sell 20% of all tickets using a dynamic price by the end of the year. Edward H. Bastian, the CEO of Delta, explained the strategy on an investors call last week, noting that it was “optimizing revenue through [its] partnership

Economists made a model of the U.S. economy. Our debt crashed the model

People have been worrying about U.S. debt basically ever since there even was a U.S. “The accumulation of debts is a most fearful evil,” Thomas Jefferson wrote in 1787. At the time, U.S. debt was around $40 million. Today, it’s closer to $40 trillion. At the same time, the U.S. economy is bigger and more powerful than Jefferson could have ever imagined, and things are looking pretty good: unemployment is near record lows, inflation is under control… so what’s the problem? “Part of the problem i

OpenAI and Anthropic researchers decry ‘reckless’ safety culture at Elon Musk’s xAI

AI safety researchers from OpenAI, Anthropic, and other organizations are speaking out publicly against the “reckless” and “completely irresponsible” safety culture at xAI, the billion-dollar AI startup owned by Elon Musk. The criticisms follow weeks of scandals at xAI that have overshadowed the company’s technological advances. Last week, the company’s AI chatbot, Grok, spouted antisemitic comments and repeatedly called itself “MechaHitler.” Shortly after xAI took its chatbot offline to addre

Top AI Researchers Concerned They’re Losing the Ability to Understand What They’ve Created

Researchers from OpenAI, Google DeepMind, and Meta have joined forces to warn about what they're building. In a new position paper, 40 researchers spread across those four companies called for more investigation of AI powered by so-called "chains-of-thought" (CoT), the "thinking out loud" process that advanced "reasoning" models — the current vanguard of consumer-facing AI — use when they're working through a query. As those researchers acknowledge, CoTs add a certain transparency into the inn

5 reasons why I still prefer Perplexity over every other AI chatbot

Stefani Reynolds/Bloomberg via Getty Images I've been working with artificial intelligence (AI) since the 1970s, when Lisp was state-of-the-art. Lately, like everyone else, I've been looking at AI a lot more closely. While it's nifty and getting genuinely useful, it can still blunder, like the time Google's AI Overviews recommended users to eat "at least one small rock per day." AI can also lose its mind, such as when Grok went totally MechnaHitler. Even when I tell J. Random Chatbot to summari

Elon Musk Said Grok 4 Was the "Smartest AI in the World," But Its Leaderboard Scores Just Came Out and They Tell a Different Story

Elon Musk has been boasting about what he says are the incredible capabilities of xAI's new Grok 4 AI chatbot. "Grok 4 is smarter than almost all graduate students in all disciplines, simultaneously," Musk bragged, adding that Grok 4 was "the smartest AI in the world." Is it really? Intelligence was a hard thing to measure even before back before AI hit the scene, but certain tests can provide something of a clue. One prominent platform for doing so is the UC Berkeley-developed LMArena leader

Hierarchical Modeling (H-Nets)

The best AI architectures in use today treat all inputs equally. They process each input with the same amount of compute, without explicitly grouping related inputs into higher level concepts. While these architectures have achieved impressive results across domains, this lack of hierarchy has some fundamental limitations. Models have difficulty learning from high resolution, raw data, requiring inputs to be pre-processed into meaningful tokens for strong performance. The use of hand-crafted p

I replaced my Galaxy S25 Plus with the S25 Edge (and Samsung may do the same)

Kerry Wan/ZDNET The Galaxy S25 Edge was my unexpected favorite phone in Samsung's S-series lineup this year. I previously wrote about how it had one major fault, but is the compact phone for content consumption in 2025. It just might not make sense to exist alongside the Plus model with the adoption of silicon-carbon batteries -- and Samsung might agree.

Research leaders urge tech industry to monitor AI’s ‘thoughts’

AI researchers from OpenAI, Google DeepMind, Anthropic, as well as a broad coalition of companies and nonprofit groups, are calling for deeper investigation into techniques for monitoring the so-called thoughts of AI reasoning models in a position paper published Tuesday. A key feature of AI reasoning models, such as OpenAI’s o3 and DeepSeek’s R1, are their chains-of-thought or CoTs — an externalized process in which AI models work through problems, similar to how humans use a scratch pad to wo

The Hidden Costs of AI: How Small Inefficiencies Stack Up

AI is having a major impact on society, from consumer technologies to driving businesses. But among all these large language models and deep neural networks, there are lurking inefficiencies that most people aren’t taking into account. Wasted computational power, hidden costs, the environmental footprint, and more. Whether these inefficiencies are big or small, they all add up. With 58% of companies planning on increasing their investments in AI this year, it’s essential these decision-makers k

xAI says it has fixed Grok 4’s problematic responses

When xAI launched Grok 4 last week, the company claimed the large language model outperformed several competitors on different benchmarks. But the Grok account on X that runs off the model immediately showed there were some major issues: it started saying its surname was “Hitler”, tweeted antisemitic messages, and seemed to reference Elon Musk’s posts when asked about controversial topics, siding with the xAI owner’s views as a result. xAI soon afterwards apologized for Grok’s behavior.

AI text-to-speech programs could “unlearn” how to imitate certain people

AI companies generally keep a tight grip on their models to discourage misuse. For example, if you ask ChatGPT to give you someone’s phone number or instructions for doing something illegal, it will likely just tell you it cannot help. However, as many examples over time have shown, clever prompt engineering or model fine-tuning can sometimes get these models to say things they otherwise wouldn’t. The unwanted information may still be hiding somewhere inside the model so that it can be accessed

Meta built its AI reputation on openness — that may be changing

Top members of Meta’s new Superintelligence Lab discussed pivoting away from the company’s powerful open source AI model, Behemoth, and instead developing a closed model, reports The New York Times. Sources told The Times that Meta had completed training on Behemoth, but delayed its release due to underwhelming internal performance. When the new Superintelligence Lab launched, testing on the model reportedly halted. The discussions are just that — discussions. Meta CEO Mark Zuckerberg would st

Context Rot: How increasing input tokens impacts LLM performance

Recent developments in LLMs show a trend toward longer context windows, with the input token count of the latest models reaching the millions. Because these models achieve near-perfect scores on widely adopted benchmarks like Needle in a Haystack (NIAH) [1], it’s often assumed that their performance is uniform across long-context tasks. However, NIAH is fundamentally a simple retrieval task, in which a known sentence (the “needle”) is placed in a long document of unrelated text (the “haystack”)
