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.»

Can Chemicals Turn My Orange iPhone 17 Pink? Here’s What I Found Out

There are reports that some cosmic orange iPhone 17 Pro handsets are turning pink. I threw chemicals at my iPhone to see what would happen.

A recent Reddit thread suggests that it’s possible for a cosmic orange iPhone 17 Pro to turn vibrant pink. As PCMag’s Eric Zeman noted, it’s likely that the phone has been discolored by cleaning substances that affected the finish, turning it from vibrant orange to a wild hot pink. Sure, this might technically be a fault, but in all honesty I love pink phones and the idea of a hot pink iPhone 17 Pro filled me with joy. So I wanted to see if I could test the theory and see just what color-changing effects various household cleaners might have on my phone.

It’s important to note here that the iPhone 17 Pro I used was bought by CNET for the purposes of testing. Had I paid over $1,000 of my own money I wouldn’t be so reckless in smearing it with chemicals that could potentially irreparably harm it. And you shouldn’t either. If you need to clean your phone, do it safely. Disclaimer aside, let’s dive in.

The chemicals

I bought two chemicals to test this out. Zeman explains that it may be oxidation that caused the color to change and that hydrogen peroxide could do this. I couldn’t find this over the counter in the UK, so I instead bought an «oxy-active» stain remover spray that, among other things, contains «oxygen-based bleaching agents» which sounded ideal. Apple also clearly states «don’t use products containing bleach or hydrogen peroxide» on its support page so, naturally, I bought some thick bleach too.

Oxy application

I started by spraying the oxy cleaner on a microfiber cloth until it was noticeably wet from the liquid and then liberally applied this all over the rear of the iPhone. The Reddit user with the affected phone showed that it only affected the metal parts, not the glass back panel, so I made sure to focus my attention on the sides and camera bar.

With the phone well and truly doused in chemicals that have no business being anywhere near a phone, I left it to sit and think about what it had done for 30 minutes — after which time I wiped it dry and took a close inspection. Disappointingly, my phone was still factory orange, rather than «what the hell have you done to your phone» pink. Time to move on.

Bleach blast

I opened the bleach and trying hard not to think about my days as a middle school cleaner, applied a liberal blob of the stuff to a cloth and smeared it over the defenceless phone, concentrating again on the metal areas. I definitely should have worn protective gloves for all of this so please make sure you take better care of yourself than I do if you do anything with bleach.

Again, I gave it a 30-minute settling in period before cleaning it off and inspecting the results.

The phone remained as orange as ever, looking as box fresh as it was the day before when it was, indeed, box fresh. The orange color hadn’t changed and now almost 24 hours later there’s still no sign of discoloration of any kind.

Is the pink iPhone 17 real?

I can’t say with any certainty whether the Reddit user’s images of a pink iPhone 17 Pro are real or not. The cuddly human side of me wants to take them at their word, while the journalist in me is sceptical. What I can say with certainty is that putting your orange iPhone into close contact with household cleaning products isn’t going to win you a funky, ultra-rare pink hue that you could sell on eBay for a small fortune.

It’s possible that using pure peroxide could be the thing that does it, but to be honest, if you’re going out of your way to throw industrial-grade chemicals at your phone then you may as well just directly try and dye it. My goal here was to see how susceptible the orange model is to everyday household cleaners such as kitchen cleaner or bathroom bleach — the sort of things it might naturally come into contact with in routine use. And what I’ve found is that, no, it won’t ruin the nice orange color. But it’s probably still not good for your phone.

CNET’s key takeaways

You can get these amazing earbuds for just $139 right now at Walmart.
My teenager loves everything about them.
The sound quality is exceptional.
The noise cancellation can help give you some peace, even in a busy home.

My 13-year-old daughter loves her music and her privacy, and for years she has wanted a pair of AirPods. They’re not cheap so I’ve only been getting her more budget options, like the Amazon Echo Buds, as a result. These kept seemingly disappearing, though, so I finally ponied up for the AirPods Pro 2.

I picked them up during last year’s sales, and they were definitely well-received. She’s happy, she uses them every day, and she hasn’t lost them yet. The AirPods Pro 2 are currently on sale at Walmart for $139, a nice price for a high-quality pair like these, and one of the lowest we’ve seen.

What about the AirPods Pro 3?

The AirPods Pro 3 weren’t available at the time I bought the AirPods Pro 2, but they were rumored, and I didn’t wait to see what they offered. As CNET’s resident headphone expert, David Carnoy summarized in his AirPods Pro 3 and Pro 3 comparison, the newer model is «significantly improved in the four most important areas: fit, sound quality, noise cancellation and battery life.» They also have heart-rate monitoring, like the Beats Powerbeats Pro 2.

Hey, did you know? CNET Deals texts are free, easy and save you money.

While these are undoubtedly all important things, a lot of people aren’t going to notice the differences or make the most of the new features. With the AirPods Pro 3 being newer, they’re on a smaller sale and are currently available at Amazon for $220, which is $30 off the list price.

Why I didn’t get the AirPods 4 instead

Why did I choose AirPods Pro 2 instead of the AirPods 4 with ANC? First, as I mentioned in another article about a different pair of earbuds I bought, I think sealed, in-ear buds are better than open-design models like the AirPods 4. The seal creates another layer of noise isolation and contributes to superior sound quality, and if you want to pay attention to the world you can always engage ambient sound mode, which Apple calls transparency mode.

Also a factor was that, at the time, Carnoy considered the Pro 2 the best Apple noise-canceling wireless earbuds: «While we’re quite impressed with those new models — and with the AirPods 4 ANC in particular — the AirPods Pro 2 remain arguably the best Apple AirPods you can buy if you don’t mind having silicone ear tips jammed in your ears,» he said.

My daughter uses earplugs all the time to help her sleep, so she definitely qualifies as somebody who’s comfortable stuffing things in her ears. Like her fingers, when I start using words like «sigma,» «skibidi» and «relatable» to try to relate to her.

I asked Carnoy about the Pro 2s potentially not fitting in her kid-size ears and he reassured me that the range of eartips that come with the Pro 2s «now include XS, so they should fit.»

Do AirPods make a great gift?

It took me years to finally understand, but yes, for someone looking for wireless earbuds, AirPods — especially the Apple AirPods Pro 2 — make the perfect gift, regardless of whether you’re a teenage girl.

If You’re Flying for the Holidays, This Bluetooth Dongle Transforms In-Flight Movies, and It’s 35% Off for Black Friday

Watch airplane movies just like you would at home with this game-changing device.

Air travel for the holidays can be stressful, especially when winter weather or flight delays force a change of plans, but one perk of flying still remains — watching new-release movies. However, in-flight entertainment on most airlines usually requires a wired set of earbuds. (And the ones the airline hands out are so bad they may as well not even be connected.)

I’d far prefer to use my wireless, noise-canceling AirPods Pro, but they connect only via Bluetooth. There’s a simple tech solution that makes viewing movies on the plane feel more like watching them on your couch.

The AirFly is a simple Bluetooth dongle that allows me to connect my wireless earbuds directly to the airplane’s entertainment system, eliminating the need for adapters or wired workarounds.

It’s become a must-pack item in my travel bag. Since I started using it, I’ve stopped dreading in-flight audio and finally get to enjoy movies on the plane. If you fly often, this little gadget could completely change how you travel. And the base level AirFly SE is 35% off for Black Friday at Amazon.

The AirFly Pro lets me enjoy in-flight entertainment

The AirFly Pro from Twelve South is a minimally designed dongle that allows me to connect to the 3.5mm headphone jack in my airplane seat, enabling me to listen to in-flight entertainment on my noise-canceling earbuds.

All I have to do is pair the AirFly with the Bluetooth headphones I’m using, such as my AirPods Pro, plug the AirFly into the display in front of me, and I’m all set. I don’t even need to use my phone to connect the two devices.

There are several versions of the AirFly: the AirFly SE, which is currently on sale for $26 on Amazon and connects to just one set of headphones, the AirFly Pro at $55, the Pro V2 at $60 and the Pro 2 Deluxe at $70, which comes with an international headphone adapter and a suede travel case.

Hey, did you know? CNET Deals texts are free, easy and save you money.

I use the AirFly Pro, which has been a game-changer for me on flights. I’ve never had to worry about battery life since the AirFly Pro lasts for over 25 hours and can be fully charged in just three hours. I can also pair two separate pairs of headphones to a single AirFly Pro, in case I’m with someone else on a flight and want to watch the same movie or show.

And if that’s not enough, the AirFly Pro also doubles as an audio transmitter, allowing me to turn any speaker with a headphone jack, such as my old car stereo, into a Bluetooth speaker.

The AirFly Pro makes a great gift for any traveler

The AirFly Pro is the perfect present to give to someone who’s planning to travel this year. Besides my Anker MagSafe battery pack, the AirFly Pro has become my most treasured travel accessory when I fly, which is why I consider it one of those can’t-go-wrong gifts.
