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.»

I Tried This $40 Smartwatch: It Was Meh, but Not a Complete Waste of Time

The WITHit Giga does the basics for a lot less, but at the expense of accuracy and attention to detail.

I wasn’t expecting much when I first strapped the WITHit Giga Smartwatch onto my wrist, and at least it delivered on that. This $40 smartwatch does the basics: shows notifications, counts your steps, tracks your heart rate (sort of) and lets you take calls from your wrist. But the execution of all these features is where it all starts to fall apart, and I found myself getting exactly what I paid for.

After spending a week testing it, I came away with this: If you just want a basic smartwatch that works with both Android and iPhone, tells the time, tracks your steps and surfaces notifications, this will get the job done, just don’t expect accuracy. But if you can stretch your budget even a little, something like the $75 Amazfit Bip 6 offers more accurate tracking, a more refined design and more reliable performance.

Design and UI: big, bulky, and basic

The WITHit Giga is about as no-frills as smartwatches come. It looks like an Apple Watch Ultra impersonator: metallic frame around a rectangular screen, rounded edges and even Apple Watch-like icons inside. But that’s where the similarities end.

If your wrist is on the smaller side like mine (I have a 6-inch wrist), brace yourself because this is going to look huge. The Giga’s 48.5mm case is overpowering, and there’s no smaller size option. On my wrist, it felt bulky and out of place, and the thick, textured silicone bands definitely didn’t help matters.

The 2.04-inch AMOLED display is decent with a 386×448 resolution, but the screen brightness isn’t adaptive. You’ll need to manually adjust it, which means it’s almost too bright at night and borderline unreadable in direct sunlight unless you increase the brightness manually.

This watch runs its own proprietary system, syncs to the WITHit app and works with both Android and iOS. You’ll get notifications, basic fitness tracking, an always-on display (which in my testing drained the battery fast) and a speaker/mic combo for answering calls.

The UI is straightforward but lacks polish. Swiping right opens your favorites and the side button lets you quickly launch a workout. Animations feel slow and longer text scrolls in awkwardly to fit the screen.

Battery life: Not bad but there’s a catch

Battery life is one of the few things that holds up well here. I got about three days of use with the raise-to-wake option, and roughly a day and a half with the always on display enabled. That’s not bad for the price, and it’s actually better than even some flagship smartwatches.

But the manual comes with a big red flag: «Avoid fast chargers» and don’t overcharge. That’s not something you want to see in 2025, especially because at this point in my smartwatch charger collection I don’t know which one is fast, and which one is not, and the vague warning makes me think it’s going to explode if I make the wrong choice. Charging from an empty battery to full takes about two hours with the included magnetic charger. But once I left it charging overnight and I approached it with terror the next morning thinking I’d broken the «don’t overcharge» rule. Luckily, I came out unscathed.

Health and fitness tracking: lower your expectations

Workout tracking and wellness is where the cracks really show. Yes, the Giga technically tracks heart rate, blood oxygen (SpO2), sleep, stress and menstrual cycles. But the accuracy is questionable at best.

During workouts, heart rate measurements were consistently off when compared to a chest strap and even other wrist-based trackers. The post workout HR average was close enough, but the metrics during the workout were noticeably off. For example, as I was sitting on my Pilates reformer (completely sedentary) starting a workout on the watch, the screen already read «100bpm», while the chest strap and Apple Watch had me at 65 bpm. This made me skeptical of even the resting heart rate readings.

Sleep tracking only works between 10 p.m. and 8 a.m., meaning night shift workers or anyone with an irregular schedule (like this late-night writer) is out of luck.

Sleep stats are also confusing; instead of clear sleep stages or hours of sleep, you get odd comparisons like «fewer than 26% of people in your age group go to sleep this late.» Not exactly sure what I should do with this information.

Menstrual tracking is purely manual, based on averages, with no biological marker detection like temperature tracking. You can’t even log a period directly from the watch and have to do it from the app.

Other smartwatch features

Calls: As long as your phone is within range, you can answer and make phone calls from the watch with its speaker and mic, but clarity is an issue.
Texting: You can see texts from messaging apps, but you can’t reply or even send a prewritten response (when paired to an iPhone).
Voice Assistant: Technically available, but is basically just a shortcut to activate your own phone’s assistant. You tap, and Siri or Google Assistant opens on your phone, not the watch. Not helpful.
Quick settings: Save your recently used apps in quick settings, which actually made flipping between features like workouts and music controls more convenient — this is a win.

Should you buy it?

The WITHit Giga does the bare minimum you’d expect from a smartwatch, but at the expense of accuracy and attention to detail. For $40, it’s a functional notification mirror with step tracking, call support and a splash of health features (if you’re looking for a general overview at best).

But if you can stretch your budget, something like the $80 Amazfit Bip 6 offers far better value, accurate health tracking, cleaner UI and better battery life.

Bottom line: If you keep your expectations low, and you’re just dipping your toes in the smartwatch waters for the first time, this might suffice. Otherwise, it’s worth paying more for something that feels less like a toy and more like a tool.
