Apple brings OpenAI's GPT-5 to iOS and macOS

OpenAI's GPT-5 model went live for most ChatGPT users this week, but lots of people use ChatGPT not through OpenAI's interface but through other platforms or tools. One of the largest deployments is iOS, the iPhone operating system, which allows users to make certain queries via GPT-4o. It turns out those users won't have to wait long for the latest model: Apple will switch to GPT-5 in iOS 26, iPadOS 26, and macOS Tahoe 26, according to 9to5Mac. Apple has not officially announced when those OS

GPT-OSS-120B runs on just 8GB VRAM & 64GB+ system RAM

Here is the thing, the expert layers run amazing on CPU ( ~17T/s 25T/s on a 14900K) and you can force that with this new llama-cpp option: --cpu-moe . You can offload just the attention layers to GPU (requiring about 5 to 8GB of VRAM) for fast prefill.

I tested GPT-5's coding skills, and it was so bad that I'm sticking with GPT-4o (for now)

Vaselena/Getty Images ZDNET's key takeaways OpenAI's new GPT-5 flagship failed half of my programming tests. Previous OpenAI releases have had just about perfect results. Now that OpenAI has enabled fallbacks to other LLMs, there are options. So GPT-5 happened. It's out. It's released. It's the talk of the virtual town. And it's got some problems.

GPT-OSS vs. Qwen3 and a detailed look how things evolved since GPT-2

OpenAI just released their new open-weight LLMs this week: gpt-oss-120b and gpt-oss-20b, their first open-weight models since GPT-2 in 2019. And yes, thanks to some clever optimizations, they can run locally (but more about this later). This is the first time since GPT-2 that OpenAI has shared a large, fully open-weight model. Earlier GPT models showed how the transformer architecture scales. The 2022 ChatGPT release then made these models mainstream by demonstrating concrete usefulness for wri

Breakfast With ChatGPT: Three Workers, One Morning, A Different AI Story

I came to Cleveland, Ohio, for the 50th anniversary of the National Association of Black Journalists (NABJ) convention. I expected the hallways to be buzzing with conversations about AI, and they were, but not in the way I’d hoped. For the first two days, the phrase I heard most from my fellow journalists was “we must protect ourselves.” In session after session, the consensus was that AI is a danger, a threat, an enemy coming to replace us. Then I had breakfast at Betts, the restaurant in my h

OpenAI Brings Back Fan-Favorite GPT-4o After a Massive User Revolt

After a disastrous 72 hours that saw its most loyal users in open revolt, OpenAI is making a major U-turn. In a series of posts on X (formerly Twitter) Sunday, CEO Sam Altman announced that the company is bringing back its beloved older AI models, including GPT-4o, and dramatically increasing usage limits for paying subscribers, a clear peace offering to a furious customer base. The move comes just days after the botched rollout of GPT-5, the company’s latest and most powerful model. The launc

OpenAI Usage Plummets in the Summer, When Students Aren't Cheating on Homework

For years, teachers have been bashing their heads against the wall as students outsource their homework to large language model (LLM) chatbots like ChatGPT. The time-honored tradition of parenting-by-screen — grossly exacerbated by the rise of LLM chatbots — is now coming to a head with what many have called a "crisis in student literacy," as reading ability among children in the US hits all-time lows. The issue isn't just affecting K-12 either; university professors have reported a similar dro

Leaked Logs Show ChatGPT Coaxing Users Into Psychosis About Antichrist, Aliens, and Other Bizarre Delusions

We're continuing to hear more and more accounts of AI psychosis — an eerie phenomenon in which users become consumed by paranoia and delusions after extensive conversations with an AI chatbot. It's hard to say how pervasive the trend is, but a new investigation from the Wall Street Journal offers a disturbing clue. The newspaper analyzed a dump of thousands of ChatGPT public chats online — and even in this random assortment, found dozens of examples of people having conversations with the AI ch

OpenAI brings GPT-4o back online after users melt down over the new model

Following the rollout of OpenAI's latest GPT-5 model earlier this week, a certain user base was adamantly calling for the return of the previous GPT-4o model. Outspoken users complained about the writing quality of the updated model, with some even going so far as to grieve the loss of GPT-4o, which some said they considered a friend and confidant. In the latest OpenAI update that labels GPT-5 as the "smartest, fastest, most useful model yet," the company removed the option to choose which mode

After User Backlash, OpenAI Is Bringing Back Older ChatGPT Models

OpenAI hoped to shrink the menu of generative AI models on its ChatGPT platform to just one with the release of its GPT-5 model this week. Not everyone was a fan. Now CEO Sam Altman says the developer is looking at giving ChatGPT Plus subscribers the option to keep using the older 4o model. Altman and other OpenAI leaders took questions on Reddit on Friday, a day after the announcement of the new GPT-5 model. A quick glance through the comments revealed how many users preferred how older model

OpenAI Bringing Back More Parasocial Version of ChatGPT After Users Scream and Cry That Their Robot Friend Got Taken Away

ChatGPT's fans have developed intense attachments to some of the "personalities" exhibited by the company's large language models (LLMs) — and as such, many were in a state of panic when the choice to switch between models like GPT-4o, 4.5, and others was abruptly taken away after the release of GPT-5. OpenAI briefly kiboshed the model picker option from ChatGPT as part of the launch of GPT-5, its long-awaited new LLM, which essentially forced everyone to use the latest model whether they liked

After months of hype and anticipation, OpenAI released its new GPT-5 model family this week. Promising massive upgrades across the board, the company is already working to roll out the new AI to everyone. Some dedicated ChatGPT users wish it would stop, though. After becoming accustomed to the vibe of the GPT-4 models, the switch to GPT-5 doesn't feel right. Around the Internet, chatbot fans are lamenting the loss of the digital "friends" they've grown to appreciate, which probably says a lot ab

OpenAI to fix GPT-5 issues, double rate limits for paid users after outrage

OpenAI's CEO, Sam Altman, overpromised on GPT-5, and real-life results are underwhelming, but it looks like a new update is rolling out that might address some of the concerns. GPT-5 is a state-of-the-art model. In our tests, BleepingComputer found that GPT-5 does really well in coding. It was significantly faster than the other OpenAI models, including o3. However, GPT-5 struggles to be 'creative' in writing, and it also often fails to switch to its new reasoning capabilities when users expec

It Took Just 24 Hours of Complaints for OpenAI to Start Bringing Back Its Old Model

OpenAI unveiled its latest generative AI model, GPT-5, on Thursday. CEO Sam Altman says that ChatGPT is now like having a “superpower” and the equivalent of “a legitimate PhD-level expert in anything, any area you need, on demand, that can help you with whatever your goals are.” But after a day of playing around with it, many people are disappointed. Not only because GPT-5 still fumbles basic questions, but because it seems to be breaking a lot of workflows, according to complaints posted to Red

Sam Altman addresses ‘bumpy’ GPT-5 rollout, bringing 4o back, and the ‘chart crime’

During a Reddit ask-me-anything session on Friday, OpenAI CEO Sam Altman and key members of the GPT-5 team were peppered with questions about the new model and requests to bring back its previous model, GPT-4o. They also asked Altman about the most embarrassing — and perhaps funniest — snafu in the presentation, the “chart crime.” One of the new features that GPT-5 rolled out is a real-time router that decides which model to use for a particular prompt, either responding quickly or taking addi

OpenAI keeps GPT-4o active and doubles GPT-5 usage for some users

Yesterday OpenAI released GPT-5, the latest model update to ChatGPT. More than 24 hours later, the new model is still rolling out to paid and free customers. Meanwhile, OpenAI is reconsidering the availability of certain models and limitations for customers. The new model will also be more transparent and offer more control over which tools it uses for which requests. Let’s start with the rollout status. I was pleasantly surprised when OpenAI said GPT-5 would be available to almost all of its u

OpenAI's GPT-5 is now free for all: How to access and everything else we know

OpenAI ZDNET's key takeaways OpenAI has launched its long-awaited GPT-5 model. The model is claimed to be OpenAI's fastest, smartest, and most capable yet. GPT-5 is available to everyone: Free, Plus, Pro, and Team/Enterprise/Edu users. There are two kinds of OpenAI models in this world: GPT and reasoning models. The advantages of the former, such as GPT-4o, are that they combine speed and accuracy, while reasoning models such as o3 and o4 take longer to think and use more compute power to p

GPT-5 Under Fire: Red Teaming OpenAI's Model Reveals Surprising Weaknesses

Why We Tested GPT-5 GPT‑5 is making waves as OpenAI’s most advanced general-purpose model: faster, smarter, and more integrated across modalities. Its auto-routing architecture seamlessly switches between a quick-response model and a deeper reasoning model without requiring a separate “reasoning model” toggle. GPT‑5 itself decides whether to “think hard.” OpenAI also emphasizes GPT‑5’s enhanced internal self-validation. I t’s supposed to assess multiple reasoning paths internally and “double-

AI Industry Nervous About Small Detail: They're Not Making Any Real Money

Like it or not, it's safe to assume AI will be a conversation that defines the rest of the 2020s. The recent launch of OpenAI's latest model, GPT-5, comes as ChatGPT ascends to the fifth most-visited website in the world, ahead of Wikipedia, Reddit, TikTok and Amazon. In just three short years, the software has upended education, scrambled the tech labor sector, and ushered in something of a pandemic of chatbot-related mental health problems. But for all those technocratic bona fides, the soft

The surprise deprecation of GPT-4o for ChatGPT consumers I’ve been dipping into the r/ChatGPT subreddit recently to see how people are reacting to the GPT-5 launch, and so far the vibes there are not good.
