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.»

Google Gives Chrome an AI Side Panel and Lets Gemini Browse for You

The update also includes Nano Banana image tools and deeper integrations with Google apps like Gmail, Calendar, Maps and Flights.

Google is turning Chrome into something closer to a digital copilot.

In the next wave of Gemini updates rolling out, Google on Wednesday revealed a set of new AI-powered features coming directly to its browser, aimed at reducing the frustrations of exploring the internet each day. Built on Gemini 3, the updates introduce an always-available side panel, deeper app integrations, creative image tools and a new browser agent called auto browse that can complete multistep tasks on your behalf.

Essentially, Google wants Chrome to be like an AI wingman that browses, compares and multitasks for you.

Now you can automate browsing

To me, the standout new addition is auto browse, a browser agent designed to handle tedious and time-consuming chores. Instead of hopping between tabs, filling out forms or manually comparing prices of things like products or flights, you can ask Chrome to do the legwork.

Auto browse can research flights and hotels across different dates, collect documents, schedule appointments, manage subscriptions and help with tasks like renewing a driver’s license or filing expense reports.

In a live demo I saw, Product Lead Charmaine D’Silva used the new tools to plan a family vacation. Gemini compared destinations and prices across multiple travel sites, checked school calendars to see when her kids were off and lined up schedules to find workable travel windows. When it came time to book, though, D’Silva emphasized that the final decision and purchase were still hers, underscoring Google’s plan to keep humans in control for key tasks like booking and purchases.

The feature is rolling out to AI Pro and Ultra subscribers in the US now, signaling Google’s broader push toward more agentic AI experiences.

A new side panel experience

Another update rolling out now is a redesigned Gemini side panel in Chrome, available across MacOS, Windows and Chromebook Plus. Instead of opening a separate tab, Gemini now lives alongside whatever you’re working on, making it easier to multitask without breaking your flow. Testers have used it to summarize reviews across sites, compare shopping options and juggle packed calendars while keeping their main task front and center.

AI image editing with Nano Banana

Chrome is also trying to become more creative. Google is bringing Nano Banana, its AI image editing and generation tool, directly into the browser. You can now edit and reimagine images you find on the web without downloading files or switching apps — whether that’s mocking up a living room redesign or turning raw data into an infographic at work.

Chrome connects with other Google apps

Under the hood, Gemini in Chrome is becoming more connected to the rest of Google’s ecosystem. Integrations with Gmail, Calendar, Maps, YouTube, Google Flights and Shopping will allow the assistant to pull in relevant context and take action across apps. Planning a trip, for example, could involve referencing an old email, checking flight options and drafting a follow-up email to your travel companions. Now all in one place.

More to come

Looking ahead, Google says personal intelligence is coming to Chrome in the coming months. With user opt-in, Gemini will remember context from past interactions to deliver more tailored, proactive help across the web, while giving you control over what data is connected and when.

The Samsung Galaxy Z TriFold’s Nearly $3,000 Price Might Unfold Your Whole Wallet

This double-folding phone will be the most expensive mainstream handset released in the US.

Samsung’s twin-hinged Galaxy Z TriFold is nearly on sale, coming before the Galaxy S26 launch next month. Starting Jan. 30, foldable phone fans who want the most advanced device in the US can pick one up, but they’ll have to pay a hefty price: The device starts at a jaw-dropping $2,900.

Yes, for over three times the price of a Galaxy S25, you can pick up the most advanced smartphone — and certainly the most expensive — Samsung has ever rolled out. Even the Galaxy Z Fold 7, which starts at $2,000 with 256GB of storage, only reaches $2,420 at the highest 1TB storage configuration.

As products across all industries get costlier, phone-makers have priced foldables in an even more premium tier than the most innovative flat smartphones (like the iPhone 17 Pro Max and Galaxy S25 Ultra). It seems Samsung will use the twin-hinged Galaxy Z TriFold to set an even higher price ceiling for smartphones.

Anyone who buys the Galaxy Z TriFold will get one of the most technically impressive handsets released in the US. But is the technology worth the cost?

The Galaxy Z TriFold unfolds into a 10-inch inner display that rivals the screens of full-size tablets. It’s noticeably larger than the 8-inch inner screen on the single-hinged Galaxy Z Fold 7 foldable. Its two hinges, built of titanium, are tested to endure 200,000 folds, according to Samsung.

When unfolded, the Z TriFold is 3.9mm at its thinnest point. That’s slightly outdone by the slimmer Huawei Mate XT’s 3.6mm, which beat Samsung to market by an entire year with a trifold that’s not available in the US. That might be nearing the limit for phone thinness, as it’s barely enough to accommodate the USB-C port at the bottom of either device.

The Galaxy Z TriFold and Huawei Mate XT are roughly comparable in size and specs, though the Huawei phone’s EMUI operating system and the lack of familiar Google apps (due to the ban on US companies working with the Chinese phone-maker) mean Android fans may prefer Samsung’s. The Huawei foldable is also more expensive, starting at 3,499 euros (about $4,150 today), and may not be compatible with US carriers out of the box.

The Galaxy Z TriFold has a customized Snapdragon 8 Elite chip, the same one that powers last year’s Galaxy S25 series. It won’t feature the latest Snapdragon 8 Elite Gen 5 silicon, which is likely to power this year’s most advanced Android handsets (potentially including the upcoming, but not yet announced, Samsung Galaxy S26 series).

The Galaxy Z TriFold will start at 512GB of storage and packs a 5,600-mAh battery, larger than the Z Fold 7’s 4,400-mAh capacity unit. It recharges at 45 watts, which is typical for Samsung phones, though other premium Android handsets have long ago surpassed that rate, like the OnePlus 15 with 80-watt charging. It has three rear cameras (a 200-megapixel main, a 12-megapixel ultrawide and a 10-megapixel telephoto) and comes in a single color, crafted black.

All told, the Galaxy Z Trifold offers only marginal upgrades over the Galaxy Z Fold 7, and its hardware will likely be surpassed soon when the Galaxy S26 series launches with newer chips.

At $1,000 to $2,000 above other Android phones and foldables, the Z TriFold seems to offer only a single advantage: its massive inner display. While undeniably a technical marvel, that’s not nearly enough added value for most people to justify the steep upsell on your standard smartphone, or even another book-style foldable. For folks who «crave» the most advanced phone on the market, though, maybe it’s worth the expense.
