• Altman's tweet suggests that ChatGPT-5 Pro is coming to Plus subscribers
• It will be limited to a few queries a month
• The move would add more confusion to the ChatGPT Plus model selector

Following the backlash against OpenAI removing ChatGPT-4o when it introduced ChatGPT-5, the AI giant has now restored access to ChatGPT-4o, but only for ChatGPT Plus subscribers.

Free tier users are limited to just ChatGPT-5 for now, but it seems that CEO Sam Altman and OpenAI aren’t done making changes to its LLM lineup just yet.

In reply to a post on X praising how good GPT-5 Pro is, Altman responded, “We are considering giving a (very) small number of GPT-5 Pro queries each month to Plus subscribers so they can try it out!”

we are considering giving a (very) small number of GPT-5 pro queries each month to plus subscribers so they can try it out! i like it too.but yeah if you wanna pay us $1k a month for 2x the input tokens feels like we should find a way to make that happen... https://t.co/9qC0rsDl6zAugust 11, 2025

Plus users currently get a choice between ChatGPT-5 for fast answers and ChatGPT-5 Thinking for slower, but more thoughtful answers. ChatGPT Pro is essentially the best of both worlds, delivering thoughtful answers at speed.

Making even a few queries a month available to Plus users would represent a serious added value to the $20 (£20 / AU$30) monthly subscription. OpenAI describes ChatGPT-5 Pro as “research grade” AI, and it’s currently only available to $200 (£200 / AU$300) a month ChatGPT Pro subscribers.

Before I get too excited, perhaps it's worth noting the word “considering” is contained in Altman’s tweet, and means that this isn’t definitely going to happen. However, if Altman thinks it’s a good idea, then, being the CEO, he can probably make it happen.

Part of the ethos of ChatGPT-5 was to do away with the confusing LLM line-up and naming conventions that had arisen around ChatGPT-4. The streamlined ChatGPT-5 was supposed to simplify all the different options and intelligently decide which version of the model your query would best respond to.

By giving Plus users access to ChatGPT-5 Pro, in addition to reintroducing ChatGPT-4o, we will essentially be back in the same old situation where people are given too much choice about which model to use, meaning that OpenAI still has a product naming and line-up problem.

LG and Samsung have been locked in an OLED TV battle for a number of years, ever since Samsung reentered the OLED TV market in 2022 with the Samsung S95B.

Samsung has since been our TV of the year winner for two years in a row, with the Samsung S90C taking the crown in 2023 and the Samsung S95D taking the title in 2024. Even so, several LG OLED models still sit on our list for the best OLED TV.

I’ve already tested both brands' 2025 flagship models, the LG G5 and Samsung S95F, side-by-side. Recently, however, I also had the chance to do a side-by-side test of their entry-level OLEDs, the LG B5 and Samsung S85F.

It’s worth noting that both these TVs use the same standard W-OLED display panel. So they can’t really be that different, right? Well, let’s look at the results of my comparison to find out.

With both TVs using the same panel, I expected their brightness measurements to be similar, and that did turn out to be the case. When I measured peak HDR brightness for both TVs, the LG B5 clocked in at 668 nits, and the S85F at 777 nits. I assumed a difference of just over 100 nits wouldn’t make an impact on the picture, but I was wrong.

Although the difference was subtle, the S85F’s picture did have bolder highlights in specific movie scenes. Watching The Batman, highlights from light sources such as lamps and torches in the opening subway fight and crime scene sections were indeed brighter on the S85F. The B5 still demonstrated solid brightness, but I found my eye more drawn to the S85F’s picture.

In demo footage from the Spears & Munsil UHD Benchmark 4K Blu-ray, with images such as the sun behind a satellite dish or a horizon at sunset, the S85F had a bit more vibrancy, which made these highlight areas look more striking.

Both the B5 and S85F demonstrated excellent contrast throughout testing. In The Batman, light sources balanced well with dark tones on screen, creating a good sense of contrast, though the S85F’s higher brightness gave it an edge.

Both TVs also had refined shadow detail when watching The Batman, but the B5 displayed deeper, richer black tones, and it better maintained shadow detail, with the S85F showing minor black crush. In Oppenheimer’s black and white scenes, both TVs again showed a good range of gray tones, but here again, the B5 maintained details in darker areas more accurately than the S85F.

I noticed that while Filmmaker Mode was the more accurate mode for darker movies such as Oppenheimer and The Batman, the differences between the two TVs were more obvious in Cinema mode, especially when it came to brightness, contrast and shadow detail.

Where the B5 and S85F really differed was in their color. Although both use the same OLED panel type, the S85F’s colors had a greater visual punch, especially when evaluating both TVs with their Cinema picture preset active.

In Wicked, during the Wizard & I scene where Elphaba stands under some pink flowers, the flowers looked more vibrant on the S85F than the B5, giving them an eye-popping quality. Elphaba’s green skin also appeared brighter, and later in the Emerald City, the greens appeared more dazzling on the S85F.

Where the B5 differed here was in its color depth. The B5’s deeper blacks had the effect of making the pink flowers and Elphaba’s green skin look richer and more lifelike compared to the S85F.

In the same Spears & Munsil footage, shots of colorful butterflies and flowers looked rich and refined on both TVs, but once again, the B5 displayed deeper, richer, and more subtle hues, whereas the S85F had more outright colorful images. I found myself more drawn to the S85F, especially with both TVs in Cinema mode.

One thing I wanted to test on these TVs was sports viewing. OLEDs typically have very good motion handling, which is why they always feature in our best TVs for sport guide. I’ve found that Samsung TVs require more setup effort when it comes to sports than LG TVs, and it was no different with the S85F.

In Standard mode (color in the B5’s Sports mode is too oversaturated, so I preferred not to use it), the LG B5 displayed superior motion handling. An MLS soccer game I watched via Prime Video in this mode looked fluid and smooth throughout viewing, with no settings changes required.

The S85F, also in its Standard preset, showed several motion artifacts, such as a ghosting ball and some stuttering. Changing blur and judder reduction to 5 did help, but even then, there was some picture judder compared to the B5.

Of the two TVs, the B5 was the clear winner when it came to motion handling.

After testing both the LG B5 and Samsung S85F side-by-side, the differences are generally subtle, so which one you should buy will likely come down to personal preference.

If you want a brighter, bolder-looking TV with more vibrant color, opt for the S85F. If you want a more natural-looking TV with richer blacks, opt for the B5.

Both TVs have the full suite of gaming features we look for on the best gaming TVs, and both have great smart TV platforms. But sports fans will want to go for the B5 due to its superior motion handling.

During my testing, I ultimately found myself more drawn to the S85F. So that’s the one I’d choose, but it was very close.

Honestly, it could all come down to discounts. The 55-inch B5 costs $1,499.99 / £1,399 / AU$1,995, and the 55-inch Samsung S85F costs $1,499.99 / £1,399 / AU$2,495, so in the US and UK, there's currently nothing between them. But as we approach the end of the year, both TVs will inevitably receive discounts, and the amount of those discounts could determine which TV is the better overall value.

• Modat found more than 1.2 million misconfigured devices leaking info
• This includes MRI scans, X-rays, and other sensitive files, together with patient contact data
• The healthcare industry needs a proactive approach to cybersecurity, researchers warn

Researchers have warned there are currently over a million internet-connected healthcare devices which are misconfigured, leaking all the data they generate online - putting millions of people at risk of identity theft, phishing, wire fraud, and more.

Modat recently scanned the internet in search of misconfigured, non-password protected, devices and their data, and by using the tag ‘HEALTHCARE’, they found more than 1.2 million devices which were generating, and leaking, confidential medical images including MRI scans, X-rays, and even blood work, of hospitals all over the world.

“Examples of data being leaked in this way include brain scans and X-rays, stored alongside protected health information and personally identifiable information of the patient, potentially representing both a breach of patient’s confidentiality and privacy,” the researchers explained.

In some cases, the researchers found information unlocked and available for anyone who knows where to look - and in other cases, the data was protected with such weak and predictable passwords that it posed no challenge to break in and grab them.

“In the worst-case scenario, leaked sensitive medical information could leave unsuspecting victims open to fraud or even blackmail over a confidential medical condition,” they added.

In theory, a threat actor could learn of a patient’s condition before they do. Together with names and contact details, they can reach out to the patient and threaten to release the information to friends and family, unless they pay a ransom.

Alternatively, they could impersonate the doctor or the hospital and send phishing emails inviting the victim to “view sensitive files” which would just redirect them to download malware or share login credentials.

The majority of the misconfigured devices are located in the United States (174K+), with South Africa being close second (172K+). Australia (111K+), Brazil (82K+), and Germany (81K+) round off the top five.

For Modat, a proactive security culture “beats a reactive response”.

“This research reinforces the urgent need for comprehensive asset visibility, robust vulnerability management, and a proactive approach to securing every internet-connected device in healthcare environments, ensuring that sensitive patient data remains protected from unauthorized access and potential exploitation," commented Errol Weiss, Chief Security Officer at Health-ISAC.

Online game chats are notorious for vulgar, offensive, and even criminal behavior. Even if only a tiny percentage, the many millions of hours of chat can accumulate a lot of toxic interactions in a way that's a problem for players and video game companies, especially when it involves kids. Roblox has a lot of experience dealing with that aspect of gaming and has used AI to create a whole system to enforce safety rules among its more than 100 million mostly young daily users, Sentinel. Now, it's open-sourcing Sentinel, offering the AI and its capacity for identifying grooming and other dangerous behavior in chat before it escalates for free to any platform.

This isn’t just a profanity filter that gets triggered when someone types a curse word. Roblox has always had that. Sentinel is built to watch patterns over time. It can track how conversations evolve, looking for subtle signs that someone is trying to build trust with a kid in potentially problematic ways. For instance, it might flag a long conversation where an adult-sounding player is just a little too interested in a kid’s personal life.

Sentinel helped Roblox moderators file about 1,200 reports to the National Center for Missing and Exploited Children in just the first half of this year. As someone who grew up in the Wild West of early internet chatrooms, where “moderation” usually meant suspecting that people who used correct spelling and grammar were adults, I can’t overstate how much of a leap forward that feels.

Open-sourcing Sentinel means any game or online platform, whether as big as Minecraft or as small as an underground indie hit, can adapt Sentinel and use it to make their own communities safer. It’s an unusually generous move, albeit one with obvious public relations and potential long-term commercial benefits for the company.

For kids (and their adult guardians), the benefits are obvious. If more games start running Sentinel-style checks, the odds of predators slipping through the cracks go down. Parents get another invisible safety net they didn’t have to set up themselves. And the kids get to focus on playing rather than navigating the online equivalent of a dark alley.

For video games as a whole, it’s a chance to raise the baseline of safety. Imagine if every major game, from the biggest esports titles to the smallest cozy simulators, had access to the same kind of early-warning system. It wouldn’t eliminate the problem, but it could make bad behavior a lot harder to hide.

Of course, nothing with “AI” in the description is without its complications. The most obvious one is privacy. This kind of tool works by scanning what people are saying to each other, in real time, looking for red flags. Roblox says it uses one-minute snapshots of chat and keeps a human review process for anything flagged. But you can’t really get around the fact that this is surveillance, even if it’s well-intentioned. And when you open-source a tool like this, you’re not just giving the good guys a copy; you also make it easier for bad actors to see how you're stopping them and come up with ways around the system.

Then there’s the problem of language itself. People change how they talk all the time, especially online. Slang shifts, in-jokes mutate, and new apps create new shorthand. A system trained to catch grooming attempts in 2024 might miss the ones happening in 2026. Roblox updates Sentinel regularly, both with AI training and human review, but smaller platforms might not have the resources to keep up with what's happening in their chats.

And while no sane person is against stopping child predators or jerks deliberately trying to upset children, AI tools like this can be abused. If certain political talk, controversial opinions, or simply complaints about the game are added to the filter list, there's little players can do about it. Roblox and any companies using Sentinel will need to be transparent, not just with the code, but also with how it's being deployed and what the data it collects will be used for.

It's also important to consider the context of Roblox's decision. The company is facing lawsuits over what's happened with children using the platform. One lawsuit alleges a 13‑year‑old was trafficked after meeting a predator on the platform. Sentinel isn't perfect, and companies using it could still face legal problems. Ideally, it would serve as a component of online safety setups that include things like better user education and parental controls. AI can't replace all safety programs.

Despite the very real problems of deploying AI to help with online safety, I think open-sourcing Sentinel is one of the rare cases where the upside of using AI is both immediate and tangible. I’ve written enough about algorithms making people angry, confused, or broke to appreciate when one is actually pointed toward making people safer. And making it open-source can help make more online spaces safer.

I don’t think Sentinel will stop every predator, and I don’t think it should be a replacement for good parenting, better human moderation, and educating kids about how to be safe when playing online. But as a subtle extra line of defense, Sentinel has a part to play in building better online experiences for kids.

• Fraudulent TikTok Shops driving victims into fake portals designed to steal cryptocurrency and data
• Scammers mimic trusted seller profiles and lure shoppers with unrealistic discounts across popular platforms
• SparkKitty malware secretly collects sensitive data from devices, enabling long-term unauthorized surveillance and control

Cybercriminals are now making use of TikTok Shops to spread malware and steal funds from unsuspecting young users of the platform.

The campaign, revealed by security experts at CTM360, mimics the profile of legitimate ecommerce sellers to build its credibility, often using AI-generated content.

In addition to TikTok, these fake shops can also be found on Facebook, where their modus operandi is to advertise massive price cuts to lure potential victims.

The main target of these malicious actors is not only to defraud users, mostly in cryptocurrency, but also to deliver malicious software and steal login details.

At the moment, TikTok Wholesale and Mall pages have been linked to over 10,000 such fraudulent URLs.

These URLs, which look like official platforms, offer “buy links” that redirect visitors to a criminal phishing portal.

Once users click the link and enter the portal, they will be made to pay a deposit into an online wallet or purchase a product – the online wallet is fake and the product does not exist.

Some operations take the deception further by posing as an affiliate management service, pushing malicious apps disguised as tools for sellers.

More than 5,000 app download sources have been uncovered, many using embedded links and QR codes to bypass traditional scrutiny.

One identified threat, known as SparkKitty, is capable of harvesting data from both Android and iOS devices.

It can enable long-term access to compromised devices, creating ongoing risk even after the initial infection.

The malware is often delivered through these fake affiliate applications, turning what appears to be a legitimate opportunity into a direct path for account takeover and identity theft.

Because cryptocurrency transactions are irreversible, victims have little recourse once funds are transferred.

A common thread in the campaign is the use of pressure tactics, with countdown timers or limited-time discounts designed to force quick decisions.

These tactics, while common in legitimate marketing, make it harder for users to pause and assess the authenticity of an offer.

Domain checks reveal many of the scam sites using inexpensive extensions such as .top, .shop, or .icu, which can be purchased and deployed rapidly.

• Make sure you check the website address carefully before entering your payment information. Every detail of the website should match the legitimate domain.
• Ensure that you use secure HTTPS encryption
• If the price cut feels too huge, follow your gut and stay away.
• Do not allow a countdown timer to pressure you into making payment; this pressure is a common tactic my malicious actors
• Always insist on the standard payment methods and avoid direct wire transfers or cryptocurrency, as these are harder to trace and often used in scams.
• Install and maintain a trusted security suite that combines robust antivirus protection with real-time browsing safeguards to block malicious websites.
• Configure your firewall to actively monitor and filter network traffic, preventing unauthorized access and blocking suspicious connections before they reach your device.
• Pay close attention to alerts from reputable security programs, which can detect and warn you about known phishing sites or fraudulent activities in real time.
• Remain cautious even when shopping on professional-looking platforms, as well-designed storefronts can still conceal sophisticated attempts at theft.

OpenAI CEO Sam Altman and several other researchers and engineers came to Reddit the day after debuting the powerful new GPT-5 AI model for the time-honored tradition of an Ask Me Anything thread.

Though the discussion ranged over all kinds of technical and product elements, there were a few topics that stood out as particularly important to posters based on the frequency and passion with which they were discussed. Here are a few of the most notable things we learned from the OpenAI AMA.

The biggest recurring theme in the AMA was a mournful wail from users who loved GPT-4o and felt personally attacked by its removal. That's not an exaggeration, as one user posted, “BRING BACK 4o GPT-5 is wearing the skin of my dead friend.”To which Altman replied, “what an…evocative image. ok we hear you on 4o, working on something now.”

This wasn’t just one isolated request, either. Another post asked to keep both GPT-4o and GPT-4.1 alongside GPT-5, arguing that the older models had distinct personalities and creative rhythms. Altman admitted they were “looking into this now.”

Most requests were a little more subdued, with one poster asking, “Why are we getting rid of the variants and 4o when we all have unique communication styles? Please bring them back!”

Altman’s answer was brief but direct in conceding the point. He wrote, “ok, we hear you all on 4o; thanks for the time to give us the feedback (and the passion!). we are going to bring it back for plus users, and will watch usage to determine how long to support it."

It is interesting that so many heavy users seem to prefer the style of the older model, and prefer it to the objectively better newer ones.

Another big topic was ChatGPT's safety filter, both currently and before GPT-5 which many posted complaints about for being overzealous. One user described a scenario where they’d been flagged for discussing historical topics, with a response about Gauguin getting flagged and deleted because the artist was a "sex pest," and the user's own clarification question itself getting flagged.

Altman’s answer was a mixture of agreement and reality check. “Yeah, we will continue to improve this,” he said. “It is a legit hard thing; the lines are often really quite blurry sometimes.” He stressed that OpenAI wants to allow “very wide latitude” but admitted that the boundary between unsafe and safe content is far from perfect, but that "people should of course not get banned for learning."

Another questioner zeroed in on a gap in OpenAI’s subscription model: "Are you guys planning to add another plan for solo power users that are not pros? 20$ plan offers too little for some, and the $200 tier is overkill."

Altman’s answer was succinct, simply saying, “Yes we will do something here.” No details, just a confirmation that the idea’s on the table. That brevity leaves open possibilities from 'next week' to just saying 'the discussion starts now.' But the pricing gap is a big deal for power users who find themselves constrained by the Plus tier but can’t justify enterprise pricing. If OpenAI does create an intermediate tier, it could reshape how dedicated individual users engage with the platform.

At the end of the AMA, Altman shared some new information about the current and future state of ChatGPT and GPT-5. He started by admitting to some issues with the release, writing that "we expected some bumpiness as we roll out so many things at once. But it was a little more bumpy than we hoped for!"

That bumpiness ended up making GPT-5 seem not as impressive as it should have until now.

"GPT-5 will seem smarter starting today," Altman wrote. "Yesterday, we had a sev [severity, meaning system issue] and the autoswitcher was out of commission for a chunk of the day, and the result was GPT-5 seemed way dumber."

He also promised more access for ChatGPT Plus users, with double the rate limits, as well as the upcoming return of GPT-4o, at least for those same subscribers. The AMA did paint a clearer picture of what OpenAI is willing to change in response to public pressure.

The return of GPT-4o for Plus users at least acknowledges that raw capability isn’t the only metric that matters. If users are this vocal about keeping an older model alive, future releases of GPT-5 and beyond may be designed with more deliberate flavors built in beyond just the personality types promised for GPT-5.

While the new ‘Liquid Glass’ look and a way more powerful Spotlight might be the leading features of macOS Tahoe 26, I’ve found that bringing over a much-loved iPhone feature has proven to be the highlight after weeks of testing.

Live Activities steal the show on the iPhone, thanks to their glanceability and effortless way of highlighting key info, whether it’s from a first or third-party app. Some of my favorites are:

• Flighty displays flight tracking details in real-time, for myself, family, or friends
• Airlines like United show my seat, a countdown for boarding, or even baggage claim
• Rideshare apps tell you what kind of car you're driving is arriving in
• Apple Sports displays your favorite teams' live scores in real-time with the game

Now, all of this is arriving on the Mac – right at the top navigation bar, near the right-hand side. They appear when your iPhone is nearby, signed into the same Apple Account, and mirror the same Live Activities you’d see on your phone. It’s a simple but powerful addition.

Considering Apple brought iPhone Mirroring to the Mac in 2024, this 2025 follow-up isn’t surprising. But it’s exactly the kind of small feature that makes a big difference. I’ve loved being able to check a score, track a flight, or see my live position on a plane – without fishing for my phone.

I’ve used it plenty at my desk, but to me, it truly shines in Economy class. If you’ve ever tried balancing an iPhone and a MacBook Pro – or even a MacBook Air – on a tray table, you know the awkward overlap. I usually end up propping the iPhone against my screen, hanging it off the palm rest, or just tossing it in my lap. With Live Activities on the Mac, I can stick to one device and keep the tray table clutter-free.

Considering notifications already sync, iPhone Mirroring arrived last year, Live Activities were ultimately the missing piece. On macOS Tahoe, they sit neatly collapsed in the menu bar, just like the Dynamic Island on iPhone, and you can click on one to expand and see the full Live Activity. Another click on any of these Live Activities quickly opens the app on your iPhone via the Mirroring app – it all works together pretty seamlessly.

You can also easily dismiss them, as I have found they automatically expand for major updates, saving screen real estate on your Mac. If you already have a Live Activity that you really enjoy on your iPhone, there’s really no extra work needed from the developer, as these will automatically repeat.

All-in-all, it’s a small but super helpful tool that really excels in cramped spaces. So, if you’ve ever struggled with the same balancing act as I have with a tray table, your iPhone, and a MacBook, know that relief is on the way.

It's arriving in the Fall (September or October) with the release of macOS Tahoe 26. If you want it sooner, the public beta of macOS Tahoe 26 is out now, but you'll need to be okay with some bugs and slowdowns.
