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

ChatGPT Plus subscribers can try it out now.

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

The new 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 to 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 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.

OpenAI has made its GPT technology available to developers for years, but ChatGPT, which debuted in November, offered an easy interface that yielded an explosion of interest, experimentation and worry about the downsides of the technology. ChatGPT is free, but it 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.

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.

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, 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.

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.

Crank Up the Tunes With Over $200 Off the Top-Rated Bowers & Wilkins Pi8 Earbuds

Woot is offering you the chance to put these Bowers & Wilkins Pi8 ANC buds in your ears for a massive 44% off, but the deal ends soon.

The Bowers & Wilkins Pi8 earbuds with ANC in anthracite black are now just $280 on Woot. That’s an impressive 44% off the usual $499 sticker price. It’s also the lowest price we’ve seen so far, but this deal won’t last long. Quantities on Woot are limited, so grab yours while the deal is still live.

The design’s comfy enough for long hauls, and the 15-minute quick charge is clutch when you’re heading out the door. The charging case even doubles as a Bluetooth transceiver, so you can plug into in-flight entertainment systems without fuss. These buds are featured in our roundup of the best wireless earbuds of the year, and audio expert David Carnoy called them «easily among the best-sounding earbuds out there,» with better ANC and a more ergonomic fit than earlier models.

If you’re picky about sound, these are worth a look. They have a snug fit, single-button controls and a case that’s been redesigned to feel more premium. They’re splash- and dust-resistant (IP54 rating), and the updated shape fits better than the Pi7 S2 and Pi5 S2. You can also tweak settings using the Bowers & Wilkins Music app for iOS and Android.

Apple Reportedly Eyes ‘iPhone Ultra’ Name for Folding Phone Expected This Year

It’s another week and another bunch of rumors about the company’s first foldable phone.

It’s a new week and a new set of rumors for Apple’s first foldable phone. If Tuesday’s reports are true, the device will be called the Ultra, have a bookish shape and launch in September.

The main report comes from Bloomberg’s Mark Gurman, who said the foldable is on track for a September launch, despite Nikkei Asia reporting that the phone might not launch until 2027 due to issues that cropped up during the engineering test phase.

Citing unnamed sources, Gurman said Apple will introduce the foldable phone in September alongside the iPhone 18 Pro and Pro Max. Those phones would likely go on sale about a week after being unveiled.

An Apple representative didn’t immediately respond to a request for comment. It’s important to note that while rumors abound, Apple has confirmed none of them — not even the existence of a foldable iPhone.

Still, the earlier Nikkei Asia report was jarring enough to send Apple’s stock down 5.1% before it rebounded later, Gurman noted. The Nikkei Asia story said unexpected issues had arisen during engineering testing and that more time was needed to make «necessary adjustments.» Under a worst-case scenario, the first shipment of the foldables would not occur until 2027, the report said.

Looks like a book

Meanwhile, consumer tech reviewer Sonny Dickson posted images on X showing dummy models indicating how big the iPhone Fold, iPhone 18 Pro and iPhone 18 Pro Max might be. In the image, the foldable has an almost square shape when fully opened.

Dummy images are useful for phone accessory manufacturers — such as case-makers — so they can get a head start on mass production before the devices are launched. When phones are released, consumers are quick to order cases and other accessories, so the sizes need to be known. It is unclear whether the dummy models shown are actual mockups from Apple.

People who commented on X didn’t seem to love the dummy images, particularly because the models shown appear to lack MagSafe, Apple’s magnetic system on the back of the phone that lets chargers and other accessories snap on.

Stefan Moser wrote, «If the Fold is missing MagSafe, this will be a big NO for me.»

There were other criticisms, too.

An X user going by DasnkiCS posted that the phone looks «too wide, can’t palm that easily in normal phone use.»

And another X user, Brosnan Hoban, wrote, «Fold looks like a credit card from 2050.»

What’s in a name?

Tuesday’s other big rumor concerned the foldable’s name.

A leaker, Digital Chat Station, posted on the Chinese social site Weibo that the foldable iPhone could be called the iPhone Ultra. The post also said Chinese competitors may use the Ultra name for their own foldables to compete directly with Apple on design, specs, and price.

The predominant rumored name has been the iPhone Fold, but others have included Flip, Duo and iFold.

In March, Gurman wrote in his Power On newsletter that Apple was considering a full line of Ultra products, possibly including a foldable phone, an M6 MacBook Pro with OLED, a foldable iPad and high-end Macs. Gurman also said Apple might introduce AirPods with «computer-vision cameras» to send visual data to Siri for its AI assistant feature.

We’ve seen a steady stream of tidbits about the foldable recently. There could be a large inner screen for multitasking, and people could open apps side by side. There might also be two rear cameras, a front-facing camera and a Touch ID side button.

Whatever Apple finally comes up with, it will be playing catch-up. Other major phone-makers already have foldable phones on the market, including the Samsung Galaxy Z Fold 7, the Google Pixel 10 Pro Fold, the OnePlus Open, the Huawei Mate XT, the Honor Magic V5 and the Motorola Razr Ultra.
