AI Gets Smarter, Safer, More Visual With GPT-4 Update, OpenAI Says

If you subscribe to ChatGPT Plus, you can try it out now.

The hottest AI technology foundation got a big upgrade Tuesday with OpenAI’s GPT-4 release now available in the premium version of the ChatGPT chatbot.

GPT-4 can generate much longer strings of text and respond when people feed it images, and it’s designed to do a better job avoiding artificial intelligence pitfalls visible in the earlier GPT-3.5, OpenAI said Tuesday. For example, when taking bar exams that attorneys must pass to practice law, GPT-4 ranks in the top 10% of scores compared with the bottom 10% for GPT-3.5, the AI research company said.

GPT stands for Generative Pretrained Transformer, a reference to the fact that it can generate text on its own — now up to 25,000 words with GPT-4 — and that it uses an AI technology called transformers that Google pioneered. It’s a type of AI called a large language model, or LLM, that’s trained on vast swaths of data harvested from the internet, learning mathematically to spot patterns and reproduce styles. Human overseers rate results to steer GPT in the right direction, and GPT-4 has more of this feedback.

OpenAI has made GPT available to developers for years, but ChatGPT, which debuted in November, offered an easy interface ordinary folks can use. That yielded an explosion of interest, experimentation and worry about the downsides of the technology. It can do everything from generating programming code and answering exam questions to writing poetry and supplying basic facts. It’s remarkable if not always reliable.

ChatGPT is free, but it can falter when demand is high. In January, OpenAI began offering ChatGPT Plus for $20 per month with assured availability and, now, the GPT-4 foundation. Developers can sign up on a waiting list to get their own access to GPT-4.

GPT-4 advancements

«In a casual conversation, the distinction between GPT-3.5 and GPT-4 can be subtle. The difference comes out when the complexity of the task reaches a sufficient threshold,» OpenAI said. «GPT-4 is more reliable, creative and able to handle much more nuanced instructions than GPT-3.5.»

Another major advance in GPT-4 is the ability to accept input data that includes text and photos. OpenAI’s example is asking the chatbot to explain a joke showing a bulky decades-old computer cable plugged into a modern iPhone’s tiny Lightning port. This feature also helps GPT take tests that aren’t just textual, but it isn’t yet available in ChatGPT Plus.

Another is better performance avoiding AI problems like hallucinations — incorrectly fabricated responses, often offered with just as much seeming authority as answers the AI gets right. GPT-4 also is better at thwarting attempts to get it to say the wrong thing: «GPT-4 scores 40% higher than our latest GPT-3.5 on our internal adversarial factuality evaluations,» OpenAI said.

GPT-4 also adds new «steerability» options. Users of large language models today often must engage in elaborate «prompt engineering,» learning how to embed specific cues in their prompts to get the right sort of responses. GPT-4 adds a system command option that lets users set a specific tone or style, for example programming code or a Socratic tutor: «You are a tutor that always responds in the Socratic style. You never give the student the answer, but always try to ask just the right question to help them learn to think for themselves.»

«Stochastic parrots» and other problems

OpenAI acknowledges significant shortcomings that persist with GPT-4, though it also touts progress avoiding them.

«It can sometimes make simple reasoning errors … or be overly gullible in accepting obvious false statements from a user. And sometimes it can fail at hard problems the same way humans do, such as introducing security vulnerabilities into code it produces,» OpenAI said. In addition, «GPT-4 can also be confidently wrong in its predictions, not taking care to double-check work when it’s likely to make a mistake.»

Large language models can deliver impressive results, seeming to understand huge amounts of subject matter and to converse in human-sounding if somewhat stilted language. Fundamentally, though, LLM AIs don’t really know anything. They’re just able to string words together in statistically very refined ways.

This statistical but fundamentally somewhat hollow approach to knowledge led researchers, including former Google AI researchers Emily Bender and Timnit Gebru, to warn of the «dangers of stochastic parrots» that come with large language models. Language model AIs tend to encode biases, stereotypes and negative sentiment present in training data, and researchers and other people using these models tend «to mistake … performance gains for actual natural language understanding.»

OpenAI Chief Executive Sam Altman acknowledges problems, but he’s pleased overall with the progress shown with GPT-4. «It is more creative than previous models, it hallucinates significantly less, and it is less biased. It can pass a bar exam and score a 5 on several AP exams,» Altman tweeted Tuesday.

One worry about AI is that students will use it to cheat, for example when answering essay questions. It’s a real risk, though some educators actively embrace LLMs as a tool, like search engines and Wikipedia. Plagiarism detection companies are adapting to AI by training their own detection models. One such company, Crossplag, said Wednesday that after testing about 50 documents that GPT-4 generated, «our accuracy rate was above 98.5%.»

OpenAI, Microsoft and Nvidia partnership

OpenAI got a big boost when Microsoft said in February it’s using GPT technology in its Bing search engine, including a chat features similar to ChatGPT. On Tuesday, Microsoft said it’s using GPT-4 for the Bing work. Together, OpenAI and Microsoft pose a major search threat to Google, but Google has its own large language model technology too, including a chatbot called Bard that Google is testing privately.

Also on Tuesday, Google announced it’ll begin limited testing of its own AI technology to boost writing Gmail emails and Google Docs word processing documents. «With your collaborative AI partner you can continue to refine and edit, getting more suggestions as needed,» Google said.

That phrasing mirrors Microsoft’s «co-pilot» positioning of AI technology. Calling it an aid to human-led work is a common stance, given the problems of the technology and the necessity for careful human oversight.

Microsoft uses GPT technology both to evaluate the searches people type into Bing and, in some cases, to offer more elaborate, conversational responses. The results can be much more informative than those of earlier search engines, but the more conversational interface that can be invoked as an option has had problems that make it look unhinged.

To train GPT, OpenAI used Microsoft’s Azure cloud computing service, including thousands of Nvidia’s A100 graphics processing units, or GPUs, yoked together. Azure now can use Nvidia’s new H100 processors, which include specific circuitry to accelerate AI transformer calculations.

AI chatbots everywhere

Another large language model developer, Anthropic, also unveiled an AI chatbot called Claude on Tuesday. The company, which counts Google as an investor, opened a waiting list for Claude.

«Claude is capable of a wide variety of conversational and text processing tasks while maintaining a high degree of reliability and predictability,» Anthropic said in a blog post. «Claude can help with use cases including summarization, search, creative and collaborative writing, Q&A, coding and more.»

It’s one of a growing crowd. Chinese search and tech giant Baidu is working on a chatbot called Ernie Bot. Meta, parent of Facebook and Instagram, consolidated its AI operations into a bigger team and plans to build more generative AI into its products. Even Snapchat is getting in on the game with a GPT-based chatbot called My AI.

Expect more refinements in the future.

«We have had the initial training of GPT-4 done for quite awhile, but it’s taken us a long time and a lot of work to feel ready to release it,» Altman tweeted. «We hope you enjoy it and we really appreciate feedback on its shortcomings.»

Tariff Impacts Are Real: These 13 Companies Have Confirmed Price Hikes

More and more companies are confirming price hikes as President Trump’s tariffs are poised to take effect — most recently, a popular smart lighting brand.

In many cases and for many products in the US, the biggest impacts of President Donald Trump’s aggressive tariff plans haven’t hit yet — but they could soon, unless the 90-day pause on some rates is extended. Still, numerous companies have already hiked prices or said that they’ll increase in the near-future — including, most recently, a popular and CNET-approved brand of smart lights.

The fact of the matter is that tariffs — a tax placed on the importing of certain products into a country — will ultimately cause prices to go up, with Walmart characterizing these eventual price hikes as «inevitable» during its earnings call last month. Given Trump’s push to place historically high tariffs on goods from almost every country in the world, you can also expect these price hikes to hit a huge variety of products.

This truth has begun to sink in for a lot of Americans. About 38% of consumers feel pressured to make certain purchases before tariffs cause their price to go up, according to a recent survey conducted by CNET. About 10% of respondents said they’d already made certain purchases in hopes of avoiding future price hikes, while 27% said they’d delayed purchases of products costing more than $500. Overall, these concerns about prices were felt the most around popular tech pieces such as smartphones, laptops and home appliances.

To help you keep score, I’ve put together a list of all the companies that have either confirmed or warned of price hikes due to Trump’s tariffs. As other companies make such announcements, you can expect new names to be added here.

Continue on for all those details, and for more, find out why it’s best if you wait on buying a new iPhone.

One item you won’t find on this list yet? The original Nintendo Switch, which will see a currently unspecified price hike on Aug. 1, but only in Canada for the time being. If that increase makes its way south of the border, we’ll let you know.

Best Buy

Without getting into specifics, Best Buy CEO Corie Barry told the Wall Street Journal late last month that it has already raised prices on certain products as part of its response to the tariffs.

e.l.f.

Known as an affordable option in the beauty world, e.l.f. announced in late May that it would be implementing a $1 price hike across its product line in response to the tariffs. CEO Tarang Amin claimed that the reaction from customers was positive, on account of the company’s transparency.

«We’re not trying to pull anything over on anyone,» Amin told Fortune. «This is exactly what we’re facing, and they understand.»

Macy’s

Speaking to CNBC in late May, Macy’s CEO Tony Spring said that price hikes will be implemented on some products due to tariffs, while also emphasizing that other tactics — like discontinuing certain products altogether — will also be a response to rising costs.

Mattel

Known for brands like Barbie and Hot Wheels, Mattel sounded the alarm over likely price increases during an early May earnings call. While it’s unclear how much the toymaker’s prices have increased since then, the company told investors that it would be, «where necessary, taking pricing action in its US business,» or to put it plainly, raising prices for consumers to mitigate the impact of tariffs.

Nikon

Camera-maker Nikon will introduce price hikes in response to Trump’s tariffs, effective June 23. This move will only target lenses and accessories the company makes and sells, so the cameras themselves are safe for now.

«We will be carefully monitoring any tariff developments and may adjust pricing as necessary to reflect the evolving market conditions,» a statement from Nikon explained. «We wish to thank our customers for their understanding and know that we are taking every possible step to minimize the impact on our community.»

Philips Hue

Parent company Signify announced that prices for its popular and highly regarded Philips Hue brand of smart lights will see price hikes effective July 1. The company also confirmed that this decision was made «as a direct result of tariffs.»

«Signify reserves the right to modify prices based on new or additional tariffs becoming effective in the future,» the company’s official statement explained.

Ralph Lauren

Sales at the luxury goods retailer Ralph Lauren have apparently remained steady amid recent uncertainty, but the company is still forging ahead with a plan to combat tariff impacts by raising prices more than it had already intended to, according to the Wall Street Journal.

Shein and Temu

Trump’s tariffs have made a notable target of China, hitting the country with a 30% rate only after initially hiking it all the way to 145%. Online retailers like Shein and Temu rely on direct shipments from markets like China in order to offer the rock-bottom prices that made them famous, so it’s little surprise now that they’ve had to raise prices.

The Trump administration has furthered the issues faced by these companies by doing away with a rule known as the «de minimus» exception, which used to exclude smaller purchases under $800 from import taxes. With that rule gone, Trump’s China tariffs will now apply to both bulk orders of industrial building materials and those shoes you’ve been looking to buy from Shein.

Subaru

Subaru has hiked prices across almost its entire line. The increase ranged from $750 to $2,055, depending on the model, with only the EV Solterra avoiding any change.

As has become a trend with some companies, Subaru avoided attributing the price hikes to Trump’s tariffs, citing only the common refrain of «market conditions.» Trump has notably disparaged companies that explicitly lay the blame for price hikes on his policies.

«The changes were made to offset increased costs while maintaining a solid value proposition for the customer. Subaru pricing is not based on the country of origin of its products,» a Subaru spokesperson said in a statement to Car & Driver.

Stanley Black & Decker

In an earnings report published April 30, toolmaker Stanley Black & Decker addressed «Price Actions in Response to US Tariffs,» stating that it had «implemented an initial price increase in April and notified our customers that further price action is required,» and was also looking into ways to shift its supply lines to minimize the impact of tariffs.

Volvo

The price impact of tariffs at Swedish automaker Volvo are confined, for now, to just one model: the electric EX30. Initially it was set to start at $34,950 in the US — a competitive price for an EV — but tariffs targeted at imported cars forced the company to raise the price to $46,195, a 32% bump.

Walmart

The biggest grocery chain in the US, Walmart is perhaps the most prominent company yet to announce imminent price hikes due to Trump’s tariffs. During the company’s earnings call in May, CEO Doug McMillan said price hikes would begin by the end of May and impact things like food, electronics and toys.

This Unique Controller Is Cool but Pointless for Most Gamers

The Turtle Beach Stealth Pivot has a unique 2-in-1 feature, but most people will never use it.

Pro-level game controllers have been becoming more mainstream over the past several years, offering gamers a host of new features not found on the controllers that came with their systems. These features include extra mappable buttons, swappable gamepads and other customizability options.

However, I don’t think I’ve ever seen a controller that offers two dedicated button layouts within the same device. The Stealth Pivot from Turtle Beach lets you physically rotate the gamepads to reveal a whole new, previously hidden, button layout — all without having to remove anything. It’s a unique take on what a controller can be and I’m here for it.

What I like about the Stealth Pivot

I’ve been impressed with Turtle Beach controllers for a while now, and the Stealth Pivot continues continues the company’s streak of great hardware. The buttons are clicky and responsive and the whole thing feels wonderful to hold. The design is nearly identical to Microsoft’s own Xbox controllers, which is a good thing.

The Stealth Pivot keeps many of the same pro features as its Stealth Ultra controller (and many other pro-level controllers), including adjustable triggers and four additional, remappable buttons. The Connected Command Display is carried over as well, although it’s much smaller than the Ultra’s 1.5″ screen. Amazingly, it keeps all the same features , including being able to adjust buttons and social media notifications.

On the connectivity side, you’ve got a wired connection for Xbox (there’s no wireless support), a 2.4GHz dongle for PC and Bluetooth for mobile devices and compatible smart TVs. There’s a headphone jack at the bottom and the USB-C port for charging or Xbox connection is up top. You can play and charge at the same time, which is a nice bonus.

Two controllers for the price of one

The biggest feature of the Stealth Pivot by far is its rotating gamepads. Basically, you twist down the two joysticks, unlock the gamepads, then literally rotate them 180 degrees to reveal the other set. This second set has a layout typical of controllers designed for fighting games, or really, any game where additional buttons are valuable. So instead of joysticks, there’s a D-Pad on the top left flanked by two two buttons. On the right side, the ABXY cluster shifts downward to make room for two additional, mappable buttons.

So now, instead of having to buy multiple controllers or remove and swap out gamepads (like PDP Victrix Pro controllers), in just a few seconds you can switch from snapping headshots in Call of Duty to beating up bad guys in Mortal Kombat or Tekken. It’s certainly not something I’ve ever seen on any other controller and it works surprisingly well. You can even save up to five digital profiles on the controller so you can have different layouts for each game.

I was impressed by just how good the buttons and everything are on the Stealth Pivot, even with having to cram double the amount of most everything into the same space. Granted, the controller is a bit thicker than most other controllers, but it’s not that noticeable. The hardware and engineering that went into this controller is remarkable.

What I don’t like about the Stealth Pivot

There are some compromises that come with this quick-switch capability, however. The first is that Turtle Beach wasn’t able to include its microswitch buttons, which personally I prefer over the more standard buttons on the Pivot. The joysticks are still Hall Effect, which is nice, but the rest of the buttons are standard. The buttons aren’t bad, they just aren’t as good as on the company’s other pro controller.

Secondly, making room for those rotating gamepads means space had to come from somewhere and the most obvious place was the battery. Turtle Beach says the Pivot gets about 20 hours of battery life, which is probably a bit optimistic. I wouldn’t say it’s terrible, but it’s not great. This is somewhat mitigated by the fact that you have to be physically plugged into your Xbox anyway, and you can play while charging — but PC users may want to keep a cable handy.

Also, while you can use the company’s Control Center II app to customize the controller on Windows, Xbox, iOS and Android, the app itself is not very good. The UI is basic and there are some annoying bugs including the inability to rename profiles on the Xbox version. It’s also hard to tell if anything saves after you make changes. There’s no indicator or save button anywhere, and while it does save things in real-time, it would be nice if it let you know it’s happening.

Lastly, it’s disappointing that you can’t connect wirelessly to the Xbox. Wired is fine, and it avoids battery issues, but wireless is obviously more convenient.

Should you buy the Stealth Pivot?

The Stealth Pivot is a really solid controller even without the dual personalities. Personally, I’m not really into fighting games so I don’t need the second set of controls. And super hard-core, e-sport-level gamers would probably want something like a Fight Stick or a more dedicated fighting game controller.

However, if you’re a more casual gamer who enjoys fighting/button heavy games alongside games that use joysticks — and wants to level up your fighting style — the Stealth Pivot might be worth a look, especially since it’s only $130. That is more expensive than a standard controller, but for everything you get with it, that’s a hard price to beat.
