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.

Galaxy Z TriFold vs. Huawei Mate XT: One Is the Most Versatile Phone I’ve Ever Used

Samsung’s Galaxy Z TriFold and Huawei’s Mate XT, part of a new category of phones called «trifolds,» offer diverging experiences when it comes to using them.

Huawei introduced the world’s first «trifold» phone, the Mate XT Ultimate, last year and launched it outside of China in February 2025. Despite only actually folding in two places, the phone was called a trifold because its 10.2-inch display divides into three sections.

I’ve been using it on and off since February and I liked the Mate XT so much that it made me skeptical about the Galaxy Z TriFold‘s design when Samsung first showcased it at the APEC CEO Summit in October. But after trying Samsung’s first trifold for myself, during a brief hands-on test at a Samsung store in Dubai, I changed my mind.

As foldable phone sales are expected to rise 30% year over year in 2026, according to analysts at IDC, it’s important for both Samsung and Huawei to find their own hook for customers. Each of these foldable phones has their place in the market and offers a different appeal. One is a tablet that folds into a phone, while the other is a three-in-one and the most versatile smartphone I’ve ever used. One of them has «Z TriFold» in its name but the other actually folds in a «Z» shape.

Here’s how the newly-launched Samsung trifold phone compares to the Huawei Mate XT Ultimate — the phone that pioneered this category.

Samsung Galaxy Z TriFold vs. Huawei Mate XT design

Both the Galaxy Z TriFold and Mate XT have large screens that divide into three panels (hence the name) and have two hinges to connect them. And yet, they’re vastly different.

The Huawei trifold phone has a single screen that folds in a Z shape to allow for three different forms. You can use it as a phone (fully folded), a mini-tablet (half-open), as well as a wide-screen tablet (fully opened). I’ve mostly used the Mate XT either in mini-tablet mode (one fold) or fully unfolded. And I found myself using it in phone mode (fully closed) only when I made calls.

In comparison, the Galaxy Z TriFold folds in a U shape as both panels fold inwards. You can only use it fully folded as a phone or fully opened as a wide-screen tablet, without the added ability to use it as a mini tablet.

Samsung’s Z Trifold uses two different-sized hinges and three panels of varying thickness, allowing the device’s flaps to fold on top of one another. The left hinge is like the one on the Fold 7 and comparatively tighter than the right hinge (the wider one), which springs open after you push it to a certain angle. On the back of the phone is a second display that occupies the «middle» section to use when the phone is fully closed.

When fully folded, its lowermost panel has a protruding edge, giving it a solid lip to grab onto while unfolding. It’s a nice addition to the flat-sided design, which doesn’t leave much space between panels. I found it easier to unfold than its sibling, the flat-sided Galaxy Z Fold 7.

The Huawei Mate XT has curved sides and a single screen, but because of that Z shape, it gives you three ways to use it. The right hinge unfolds like the Galaxy Z TriFold — you pull it out — but you don’t need to unfold the other side. With just one panel unfolded, it becomes a usable mini-tablet.

You can unfold the third section, at the back of the left panel, to open it fully and use it as a wide-screen tablet. Because it uses a single flexible screen, part of the soft folding display is always exposed to the elements when the device is folded shut in phone mode. So far, I haven’t noticed any scratches on the display but it is definitely less protected than Samsung’s inner screen. However, Huawei bundles a case with an extended lip to protect the always-exposed right side of the screen.

Both of these trifold phones have minimal screen creases but Samsung’s Galaxy Z TriFold feels better when I run my finger over the folding parts. While Huawei’s creases are deeper, they don’t bother me in day-to-day use. The creases on both phones are visible under direct artificial light and at an extreme angle.

The Huawei Mate XT is slimmer than the Galaxy Z TriFold. It’s just 3.6mm thick at its thinnest part when fully unfolded and 12.8mm when folded. In comparison, the Samsung phone is 3.9mm thick at its thinnest part and goes up to 12.9mm when fully unfolded. At 309 grams, the Z TriFold is also slightly heavier than the 298g Mate XT.

The Huawei trifold phone feels more premium than the Galaxy Z TriFold — probably because of its faux leather back, curved sides and gold accents. Samsung’s foldable has a carbon-fiber finish, which feels durable but not as premium.

The Mate XT has an IPX8 rating, while the Galaxy Z TriFold is rated IP48 for dust and water resistance. The «4» in IP48 means it’s protected against dust particles measuring over 1mm but not against everyday dust and pocket lint. Neither of these phones is truly dust-proof, but both are rated for water resistance, just like a standard smartphone.

Samsung Galaxy Z TriFold vs. Huawei Mate XT displays

The Galaxy Z TriFold has two screens: a Galaxy Z Fold 7-like 6.5-inch AMOLED screen with a 120Hz variable refresh rate and a 422ppi pixel density. It unfolds to a 10-inch tablet-sized screen with a 120Hz dynamic refresh rate with a lower 269ppi pixel density.

The Huawei Mate XT has a single 10.2-inch OLED screen with a 90Hz refresh rate and 382ppi pixel density. It has a lower refresh rate but a higher resolution and slimmer bezels. You can use it as a 6.4-inch phone, a 7.9-inch mini-tablet or a 10.2-inch widescreen tablet which makes it a more versatile design than Samsung’s trifold phone. The Mate XT’s display when folded down into «cover screen» has a wider aspect ratio with slimmer bezels than the TriFold’s cover display.

I haven’t watched videos on the Galaxy Z TriFold, but I assume the experience would be better on the Huawei since the main screen has a wider aspect ratio (when fully unfolded). It has less letterboxing (thick borders on top and bottom) than the Galaxy Z TriFold, which provides a slightly narrower aspect ratio when fully unfolded. However, it could be better for multitasking, especially when running three apps side by side, but I’ll need more time with the Samsung phone to come to a conclusion.

Galaxy Z TriFold vs. Huawei Mate XT performance and battery

The Samsung Galaxy Z TriFold has the Qualcomm Snapdragon 8 Elite for Galaxy chip, the same processor that powers its other 2025 flagship smartphones including the OnePlus 15. The chip is tuned for efficiency and I expect it to handle multitasking on a standalone DeX with ease. The TriFold also comes with 16GB of RAM and 512GB or 1TB of storage.

In contrast, the Huawei Mate XT runs on an in-house Kirin 9010 chip and is paired with 16GB of RAM and 512GB or 1TB of storage. It runs EMUI 14.2 operating system on global variants, which doesn’t have preinstalled Google apps. Despite the ban on US companies working with Huawei — including Google, the company behind Android — there are workarounds for installing the Play Store. You won’t encounter these kinds of hurdles on the Galaxy Z Trifold.

The Samsung trifold phone runs on One UI 8, based on Android 16. You get fast animations, smooth multitasking, a multitude of customization options and a better overall experience. The Galaxy Z TriFold will also get seven years of OS and security updates.

Both phones pack a 5,600-mAh battery but it remains to be seen how they fare against each other. I haven’t pushed the Mate XT to its limits and it delivers an entire day of use on a single charge. When I need to top up the battery, I use the bundled 66-watt charger or use wireless charging at up to 55 watts. The Galaxy Z TriFold supports 45-watt fast charging and Qi wireless charging.

Samsung Galaxy Z TriFold vs. Huawei Mate XT cameras

Both phones have three rear cameras that are identical to those found in the Galaxy Z Fold 7. The Galaxy Z TriFold has:

a 200-megapixel main camera with optical image stabilization (OIS) and a f/1.7 aperture
a 12-megapixel ultrawide camera with a 120-degree field of view
a 10-megapixel 3x optical zoom telephoto camera with OIS and support for 30x digital zoom
two 10-megapixel front-facing cameras — one inside the cover display and the other inside the folding screen

In comparison, the Huawei Mate XT has:

a 50-megapixel main camera with OIS and a variable aperture (f/1.4 — f/4.0)
a 12-megapixel 5.5x optical zoom telephoto camera with OIS
a 12-megapixel ultrawide camera with a 120-degree field of view
a 8-megapixel selfie shooter

Based on my experience with the Fold 7, you can expect vibrant colors, good dynamic range and balanced processing in low-light photos on the Samsung trifold phone. Images from the Huawei tend to have an over-processed look and it doesn’t do well with certain skin tones. But the Mate XT captures better portraits than my Fold 7. I’ll be able to test the photography chops from both phones once I have the Galaxy Z TriFold.

Here’s how the two foldable phones specs compare:
