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.»

These Small Tweaks Can Give Your Old Android a Big Speed Boost

Instead of buying a new phone, try clearing some space, updating your software and changing a few battery settings.

If your Android is a few years old and starting to feel sluggish, it doesn’t mean you have to rush out and buy the newest flagship model. Thanks to longer software support from brands like Google and Samsung, older models can still run smoothly, as long as you give them a little attention.

Before you start shopping for a replacement, try a few simple adjustments. You might be surprised by how much faster your phone feels once you clear out unused apps, optimize battery use and turn off background drains.

Whether you use a Samsung Galaxy, Motorola or OnePlus phone, chances are you can still improve battery life and overall speed without buying something new. Just remember that Android settings vary slightly from brand to brand, so the menus may look a little different depending on your phone.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

Settings to improve your battery life

Living with a phone that has poor battery life can be infuriating, but there are some steps you can take to maximize each charge right from the very beginning:

1. Turn off auto screen brightness or adaptive brightness and set the brightness level slider to under 50%

The brighter your screen, the more battery power it uses.

To get to the setting, pull down the shortcut menu from the top of the screen and adjust the slider, if it’s there. Some phones may have a toggle for auto brightness in the shortcut panel; otherwise, you need to open the settings app and search for «brightness» to find the setting and turn it off.

2. Use Adaptive Battery and Battery Optimization

These features focus on learning how you use your phone, including which apps you use and when, and then optimizing the apps and the amount of battery they use.

Some Android phones have a dedicated Battery section in the Settings app, while other phones (looking at you, Samsung) bury these settings. It’s a little different for each phone. I recommend opening your settings and searching for «battery» to find the right screen. Your phone may also have an adaptive charging setting that can monitor how quickly your phone battery charges overnight to preserve its health.

Why you should use dark mode more often

Another way to improve battery life while also helping save your eyes is to use Android’s dedicated dark mode. Any Android phone running Android 10 or newer will have a dedicated dark mode option.

According to Google, dark mode not only reduces the strain that smartphone displays cause on our eyes but also improves battery life because it takes less power to display dark backgrounds on OLED displays (used in most flagship phones) than a white background.

Depending on which version of Android your phone is running, and what company made your phone, you may have to dig around the settings app to find a dark mode. If your phone runs Android 10 or newer, you’ll be able to turn on system-wide dark mode. If it runs Android 9, don’t despair. Plenty of apps have their own dark mode option in the settings that you can use, whether or not you have Android 10.

To turn it on dark mode, open the Settings app and search for Dark Mode, Dark Theme or even Night Mode (as Samsung likes to call it). I suggest using dark mode all the time, but if you’re not sure, you can always set dark mode to automatically turn on based on a schedule, say from 7 p.m. to 7 a.m. every day, or allow it to automatically switch based on your location at sunset and sunrise.

Keep your home screen free of clutter

Planning to hit up the Google Play Store for a bunch of new Android apps? Be prepared for a lot of icon clutter on your home screen, which is where shortcuts land every time you install something.

If you don’t want that, there’s a simple way out of this: Long-press on an empty area of your home screen and tap Settings. Find the option labeled something along the lines of Add icon to Home Screen or Add new apps to Home Screen and turn it off.

Presto! No more icons on the home screen when you install new apps. You can still add shortcuts by dragging an app’s icon out of the app drawer, but they won’t appear on your home screen unless you want them to.

Set up Do Not Disturb so that you can better focus

If your phone routinely spends the night on your nightstand, you probably don’t want it beeping or buzzing every time there’s a call, message or Facebook alert — especially when you’re trying to sleep. Android offers a Do Not Disturb mode that will keep the phone more or less silent during designated hours. On some phones, this is referred to as the Downtime setting or even Quiet Time.

Head to Settings > Sounds (or Notifications), then look for Do Not Disturb or a similar name. If you can’t find it, search for it using the built-in search feature in your settings.

Using the feature, you can set up a range of hours when you want to turn off the digital noise. Don’t worry, any notifications you get while Do Not Disturb is turned on will still be waiting for you when you wake up. Also, you can typically make an exception that allows repeat callers and favorite contacts’ calls to go through. Turn that on. If someone is calling you in an emergency, odds are they are going to keep trying.

Always be prepared in case you lose your phone or it’s stolen

Is there anything worse than a lost or stolen phone? Only the knowledge that you could have tracked it down if you had turned on Google’s Find My Device feature.

To prepare for a successful recovery, here’s what you need to do: Open the Settings app and then search for Find My Device. It’s usually in the Security section of the Settings app.

If you have a Samsung device, you can use Samsung’s Find My Mobile service, which is found in Settings > Biometrics and security > Find My Mobile.

Once that’s enabled, you can head to android.com/find from any PC or mobile device and sign in to your account. Samsung users can visit findmymobile.samsung.com to find a lost phone.

If you have trouble setting any of this up, be sure to read our complete guide to finding a lost Android phone.

Assuming your phone is on and online, you should be able to see its location on a map. From there, you can make it ring, lock it, set a lock screen note to tell whoever has it how to get it back to you, or, worst-case scenario, remotely wipe the whole thing.

And always keep your phone up to date

As obvious as it may seem, a simple software update could fix bugs and other issues slowing down your Android device.

Before you download and install the latest software update, make sure your device is connected to Wi-Fi, or else this won’t work.

Now, open the Settings application and type in Update. You’ll then either see Software update or System update — choose either one. Then just download the software, wait for a few minutes and install it when it’s ready. Your Android device will reboot and install the latest software update available.

There’s a lot more to learn about a new phone. Here are the best ways to boost your cell signal, and here’s a flagship phone head-to-head comparison. Plus, check out CNET’s list of the best cases for your Samsung phone. More of an Apple fan? We have tips for boosting your iPhone’s performance, too.

I’m Finally Using the iPhone 17 Pro’s Camera Control, Thanks to These iOS 26 Settings

In just a month, I’ve already used Camera Control on my iPhone 17 Pro Max more than I did in a whole year with the iPhone 16 Pro.

I was keen on using the Camera Control button when it first debuted on the iPhone 16 Pro. But in over a year of use, it caused more accidental swipes and presses than its intended use cases to take photos and adjust camera settings. I was frustrated with the experience and hoped that Apple would remove it from the iPhone 17 lineup. Instead, the Cupertino, California-based company made its touch-sensitive capacitive control surface more customizable with iOS 26. And I’m happy to report that it helped!

I’ve been using the iPhone 17 Pro since launch and spent 5 to 10 minutes customizing the Camera Control to my liking. The result? Minimized accidental swipes and more conscious usability.

I transformed my Camera Control experience by changing a few iOS 26 settings

When setting up a new iOS 26-supported iPhone, Apple includes a toggle (now turned off by default) called Light press to adjust Zoom, Exposure and more. This is what used to cause a lot of fake input earlier. I’m glad it is turned off by default.

Apple now also lets you customize the Camera Control further from the Settings menu. I tweaked settings there to personalize my shortcuts, functionalities and more.

For example, I’ve set the Camera Control to launch a Code Scanner on Double Click without requiring the screen to be on. This allows me to scan and pay at payment kiosks (my most frequently used mode of payment) without needing to open the payment app and then tap on a menu to scan a code. If I enter the Code Scanner without Face ID, it requires authentication before making the payment, so it is still as secure as ever.

Earlier, I had set an Action Button shortcut to open Google Pay, but I realized I still need a one-press solution to turn the phone to silent mode. Adding a Code Scanner shortcut to Camera Control frees the Action Button to be my Silent Switch again. Moreover, Code Scanner lets you select from multiple apps to pay a vendor, which could be useful for people who use multiple payment apps.

Secondly, I have turned off the Swipe gesture and selected only three controls that I use most often. Now, when I open the Camera app, I can lightly press on the Camera Control button and then swipe between my selected controls. It doesn’t register swipes from the get-go. This has reduced fake touches and my frustrating experience with the swipe gesture.

To further streamline my controls, I chose Exposure, Styles and Tone, and left out Depth, Zoom and Cameras. This way, I have access to hidden viewfinder settings with a single press-and-swipe gesture at my fingertips.

I also turned off the Clean Preview toggle, so I can still switch between cameras with a single tap, and switched on the Lock Focus and Exposure toggle for a light press-and-hold gesture.

Customizing these settings helped me personalize Camera Control and use it more often. Now, it appeals to me with the settings I need and the way I need them, instead of being an overcrowded mess. And you can personalize your Camera Control, too. Here’s how:

Change Camera Control launch functionality

You can use Camera Control as another Action Button to launch an app of your choice. The only requirement is that the app should have access to the camera.

Go to Settings > Camera > Camera Control.
Under Launch Camera, select the app you need.
Go back and select Single Click or Double Click to open the said app.

I rely on Double Click so I don’t accidentally trigger an app when taking out the iPhone from my pocket. In my opinion, it is the safer and more convenient choice.

Under the same Launch Camera menu, you can also choose if you want the screen to be on or off when opening the app. I have turned it off to save the extra step of scanning my face to access the said app.

Choose the Controls that you want to appear on Camera Control

Apple allows you to choose from six controls, namely, Exposure, Depth, Zoom, Cameras, Styles and Tone. I have chosen three because the other three are available as on-screen toggles in the viewfinder.

Go to Settings > Camera > Camera Control.
Under Controls, make sure Camera Adjustments is turned on.
Tap on Customize.
Under Gesture, turn on Light Press and toggle off Swipe.
Under Controls, choose the functionalities you need.
Now, turn off the Clean Preview toggle if you require the viewfinder toggles to remain accessible.

You can further adjust the Camera Control pressure by going into Settings> Camera > Camera Control > Accessibility.

Turn on Lock Exposure and Focus with Camera Control

This setting will help you lock the exposure and focus without needing to press and hold on the viewfinder. It can be beneficial when you need consistent settings, especially when moving the camera from one subject to another.

Go to Settings > Camera > Camera Control.
Swipe down to Lock Exposure and Focus.
Tap on the toggle to turn it on.

For me, Camera Control was a hot mess when it debuted last year because I was either using on-screen controls or the new button. That’s why room for more personalization and customizability has been a game-changer. I realized I could access on-screen toggles while adding hidden settings to one-tap access. On my iPhone 17 Pro, I now use the Camera Control to open my payments app, adjust Exposure and Styles as well as trigger Visual Intelligence when needed.
