Turn your Mac into a local ChatGPT with OpenAI’s new free model

This week, OpenAI released its long-awaited open weight model called gpt-oss. Part of the appeal of gpt-oss is that you can run it locally on your own hardware, including Macs with Apple silicon. Here’s how to get started and what to expect. Models and Macs First, gpt-oss comes in two flavors: gpt-oss-20b and gpt-oss-120b. The former is described as a medium open weight model, while the latter is considered a heavy open weight model. The medium model is what Apple silicon Macs with enough res

Encryption Made for Police and Military Radios May Be Easily Cracked

Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure–as well as police, intelligence agencies, and military forces around the world–that made any communication secured with the algorithm vulnerable to eavesdropping. When the researchers publicly disclosed the issue in 2023, the European Telecommunications Standards Institute (ETSI), which developed the algorithm, advised anyone using it for

OpenAI launches new GPT-5 model for all ChatGPT users

"GPT-5 has been trained to recognize when a task can't be finished, avoid speculation and can explain limitations more clearly, which reduces unsupported claims compared to prior models," said Michelle Pokrass, a post-training lead at OpenAI. Instead of outright refusing to answer users' questions if they are potentially risky, GPT-5 will use "safe completions," OpenAI said. This means the model will give high-level responses within safety constraints that can't be used to cause harm. OpenAI s

GPT-5 is here. Now what?

Whereas o1 was a major technological advancement, GPT-5 is, above all else, a refined product. During a press briefing, Sam Altman compared GPT-5 to Apple’s Retina displays, and it’s an apt analogy, though perhaps not in the way that he intended. Much like an unprecedentedly crisp screen, GPT-5 will furnish a more pleasant and seamless user experience. That’s not nothing, but it falls far short of the transformative AI future that Altman has spent much of the past year hyping. In the briefing, A

OpenAI officially announces GPT-5, its next major upgrade to ChatGPT

ChatGPT Is Getting a Big Upgrade. Here's What's New With GPT-5

Expect your ChatGPT experience to get faster and smarter today. OpenAI updated its flagship line of large language models Thursday, unveiling the GPT-5 generative AI model after months of anticipation.

iOS 26’s Notes app adds a clever new way to use its many tools

Apple Notes gets more powerful every year, and iOS 26 adds its own batch of new features. With new capabilities comes the threat of feature bloat, but Notes has a clever solution that makes its ever-growing set of tools more easily accessible in iOS 26. iOS 26 gives Apple Notes an ‘adaptive toolbar’ Notes was once an extremely simple iPhone app. Features were minimal, as Apple prioritized just making it a quick place to jot down notes. But at some point, the company started aggressively build

OpenAI nearly confirms GPT-5 launch today - how to tune in

Elyse Betters Picaro / ZDNET ZDNET's key takeaways OpenAI's livestream at 10 AM PT/1 PM ET will likely launch GPT-5. GPT-5 will automatically select the best model for prompts, improving efficiency. That approach should help produce higher-quality answers more quickly. OpenAI just launched its highly anticipated open-source models on Tuesday, but the company is already moving on to what will likely be its biggest product launch of the year: GPT-5.

“We Miss All the Trains to Get Rich”: The Real Story of Crypto and the Black Community

I’ve been at the National Association of Black Journalists (NABJ) Annual Convention in Cleveland since August 6. I came expecting to hear about the state of our industry under Donald Trump’s second presidency, especially how to navigate the administration’s anti-DEI policies, which many in the Black community see as a direct attack on progress. I thought the talk would be about AI: how to use it, how to control it, and whether it was a threat to our profession. I definitely did not expect to ta

AI agents aren’t the ‘new Google,’ says Airbnb CEO

After a second-quarter earnings beat, Airbnb CEO Brian Chesky shared his thoughts on the company’s AI strategy, cautioning investors that AI chatbots can’t yet be thought of as the “new Google.” That is, AI chatbots, while potentially driving new leads to the travel and services business, aren’t entirely a replacement for the referrals that the dominant search engine brings. At least not at this time. “I think we’re still kind of feeling out the space,” the exec told investors on the Q2 earnin

Amazon's cloud business giving federal agencies up to $1 billion in discounts

Attendees walk through an exposition hall at AWS re:Invent, a conference hosted by Amazon Web Services, in Las Vegas on Dec. 3, 2024. Amazon Web Services has agreed to provide U.S. federal agencies with up to $1 billion in discounts for cloud adoption, modernization and training through 2028, an agency overseeing government procurement announced Thursday.

The Best Hearing Aids of 2025, Tested and Reviewed

How much money should you expect to spend on a hearing aid? The answer depends primarily on whether you’re looking into over-the-counter or prescription hearing aids. Unsurprisingly, the latter is a wallet guzzler, with average costs between $2,000 to $8,000. But OTCs can ring up quite a tab in their own right, and our most highly rated devices will still run you about $800 to $2,000 a pair. So far, we haven’t found an OTC device under this $800 price that is truly effective at treating hearing

Elad Gil isn’t just ahead of the curve — he practically lives there.

Free, offline ChatGPT on your phone? Technically possible, basically useless

Robert Triggs / Android Authority Another day, another large language model, but news that OpenAI has released its first open-weight models (gpt-oss) with Apache 2.0 licensing is a bigger deal than most. Finally, you can run a version of ChatGPT offline and for free, giving developers and us casual AI enthusiasts another powerful tool to try out. As usual, OpenAI makes some pretty big claims about gpt-oss’s capabilities. The model can apparently outperform o4-mini and scores quite close to its

How to watch OpenAI’s ‘longer than usual’ GPT-5 reveal, as teased by a Death Star

“That’s no moon,” as Obi-Wan Kenobi once said. OpenAI CEO Sam Altman stirred intrigue with a cryptic post last night showing the Death Star from Star Wars as a hint that something big is coming. That “something big” is undoubtedly GPT-5, OpenAI’s latest frontier model coming to ChatGPT. The company shared a less ambiguous post on X yesterday teasing the upcoming livestream. Since then, Altman has added that OpenAI’s next livestream will be “longer than usual” with a runtime of “about an hour.”

Welcome to dystopia: I helped ChatGPT pass a CAPTCHA and doomscroll my Facebook

Calvin Wankhede / Android Authority Last week, OpenAI released what may be the most ambitious (and potentially controversial) update to ChatGPT since its launch: Agent mode. Unlike the standard conversational interface, Agent mode gives ChatGPT control over a virtual machine running Chrome, allowing it to interact with websites like a human would. It can identify elements on websites, scroll, click buttons, fill out forms, and, if granted credentials, even log into your online accounts. For th

OpenAI’s GPT-5 leaks, hinting at better math and coding abilities

Calvin Wankhede / Android Authority TL;DR Details about OpenAI’s upcoming GPT-5 model have leaked. GitHub accidentally published details of the upcoming model and its four variants in a blog, which was later withdrawn. The leak points to better reasoning and improved agentic capabilities that may also come to ChatGPT after the model’s release. OpenAI’s long-awaited GPT-5 models are expected to arrive very soon, and are likely to be available through APIs before ChatGPT. But a recent leak has

How to disable ACR on your TV - and why it makes such a big difference doing so

Kerry Wan/ZDNET Did you know that whenever you turn on your smart TV, you invite an unseen guest to watch it with you? These days, most popular TV models utilize automatic content recognition (ACR), a form of ad surveillance technology that gathers information about everything you watch and transmits it to a centralized database. Manufacturers then use your data to identify your viewing preferences, enabling them to deliver highly targeted ads. Also: Your TV's USB port is seriously underutili

Hubble Network plans massive satellite upgrade to create global Bluetooth layer

Hubble Network’s satellite-powered Bluetooth network is getting a big upgrade.

The first two MuSat XL spa

Microsoft accidentally confirms GPT-5, GPT-5-Mini, GPT-5-Nano ahead of launch

OpenAI is hosting a live stream at 10AM PT to announce GPT-5, but Microsoft has already confirmed the details. In a GitHub document, which has now been taken offline, Microsoft confirmed GPT-5 is launching later today. While it was obvious, this is the first official confirmation. Microsoft also offered more details on GPT-5 models, including the base model, which is called just GPT-5. It is designed for logic and multi-step tasks. We also have GPT-5-mini, which is a lightweight version for c

Tornado Cash sold crypto “privacy”; the US saw “money laundering.”

"Crypto mixers" exist because of a peculiar feature of cryptocurrencies—most are fully traceable using their public blockchain ledgers. To provide more privacy to crypto account owners, a mixer will let people toss their crypto into a large pool, where it is "mixed" with other people's crypto. At a later date, each crypto owner can choose to withdraw their money from the pool into a new, anonymous wallet, thus making the movement of the crypto harder to track. Of course, the obfuscation doesn't

The Browser Company launches a $20 monthly subscription for its AI-powered browser

The Browser Company has launched a Pro subscription plan for Dia, its new web browser that heavily integrates AI features. The plan costs $20 per month and provides unlimited access to Dia’s AI-powered chat and skills features. The introduction of a paid tier means free users will now face usage limits on AI features.
