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.”

Venezuela awards U.S.-supported oil company NABEP 100-year rights to 17 oil fields, White House reports

Venezuelan interim authorities have granted U.S.-backed NABEP 100-year concessions for 17 oil fields with 65 billion barrels of proven reserves, giving the U.S. government preferential purchasing rights and an equity stake, according to the White House.

Venezuelan interim authorities have awarded U.S.-backed North American Blue Energy Partners, or NABEP, 100-year concessions for 17 oil fields, with proven reserves of approximately 65 billion barrels, the White House said on Monday.

NABEP ranks as the second-largest private oil producer in Venezuela. The company has provided the U.S. Department of War’s Office of Strategic Capital with a 35% equity stake in its corporate parent, according to the White House, representing up to “hundreds of billions in value and dividends for the United States.”

President Donald Trump announced on Friday a deal with Caracas that would grant the U.S. majority control over 65 billion barrels, or roughly 20% of the South American country’s vast oil reserves. The U.S. had approximately 46 billion barrels in proven oil reserves as of the end of 2024, according to official figures.

In a fact sheet published Monday evening in Washington, the U.S. government stated it would hold the right to purchase, at production cost, a guaranteed 20% of the off-take from all current and future fields NABEP will operate, as part of an effort to support replenishing the U.S. strategic petroleum reserves.

The U.S. government also retains the “right of first refusal” to purchase the remaining 80% of NABEP’s production, making Washington the prioritized buyer for its energy holdings.

Analysts, however, remained doubtful that this landmark oil agreement could meaningfully increase U.S. energy production or lower gas prices for Americans in the near term. Significant investments are required to extract the valuable resources in Venezuela, whose oil output remains a fraction of its potential due to decades of mismanagement, insufficient investment and sanctions.

NABEP also planned to invest up to $100 billion in new oil infrastructure in Venezuela to expand production, the White House said. Under the agreement, the company is expected to pay $200 billion in royalty and tax payments to Venezuelan governments over the first 25 years.

Tehran urges return to June deal, oil prices rise as Trump vows to hit Iran ‘hard’

Iran launched an attack on two American bases in Jordan on Monday in retaliation for the U.S. attack on its Larak Island.

Oil prices extended gains on Tuesday as traders mulled the threat of escalation, following the resumption of U.S.-Iran military strikes and more turmoil on the Strait of Hormuz.

A tanker was struck by three unknown projectiles while transiting the Strait of Hormuz on Monday, the UK Maritime Trade Operations agency said in a post on Tuesday, Asia time.

The tanker was sailing in the southern shipping lane close to the Omani coast, the UKMTO said, adding that no casualties were reported.

Iran launched an attack on two American bases in Jordan on Monday in retaliation for the U.S. attack on its Larak Island. American forces targeted two Iranian rocket launchers on Larak Island on Sunday, reportedly killing three, saying that Tehran intended to launch rockets carrying sea mines into the Hormuz Strait.

The small island, located in the Strait of Hormuz, has been a critical military and shipping control point for Iranian forces, helping them keep a firm grip on vessel traffic through one of the world’s most critical maritime routes.

Iranian President Masoud Pezeshkian told the Shanghai Cooperation Organisation Summit on Tuesday that Tehran would immediately reciprocate if Washington agreed to return to its commitments under the interim deal signed in June, according to the Iranian Student News Agency.

The back-and-forth hostilities marked the first time that the U.S. and Iran traded strikes in over a month.

While neither side appeared to be seeking a return to full-scale war, both signaled they were prepared to respond to further attacks. “We are going to hit them hard,” President Donald Trump told Fox News on Monday, saying that “there will be a response” to Iran’s attacks on U.S. military bases in the region.

Analysts largely view the U.S. attack on Larak Island as an attempt to break a deadlock rather than a shift in strategy. “By hitting the launchers rather than broader Iranian military infrastructure, the U.S. appears to be punishing a specific behaviour rather than, at least for now, broadening its war aims,” said Ali Vaez, deputy program director at International Crisis Group.

“It is enforcing the blockade,” said Jason Brodsky, policy director of United Against Nuclear Iran, adding that the Trump administration’s goal was to further degrade Tehran’s capabilities to mine the Strait of Hormuz, while focusing on economic coercive measures as the midterm elections approach.

Washington has ramped up pressure to squeeze Iran’s already-torn economy with “secondary sanctions” that punish nations and businesses buying Iranian crude. U.S. Treasury Secretary Scott Bessent said Monday, on the sidelines of the Group of 20 finance ministers’ gathering, that Iran was “lashing out kinetically” because the new sanctions were taking a toll on its economy.

Speaking from the Oval Office on Monday, Trump reportedly said Iran’s financial systems, armed forces, and governing body have largely degraded. “It doesn’t mean we won’t smack them to see what happens,” the president said.

The war, now stretching into its seventh month, has disrupted global energy supplies and sent shockwaves through global financial markets. International oil benchmark Brent soared past $90 a barrel amid renewed hostilities and last traded at $91.35 as of 2:17 a.m. ET on Tuesday. U.S. West Texas Intermediate futures added 1.07% to $86.68 per barrel.

“This is fundamentally an endurance contest,” said Brodsky, as Trump has demonstrated an “unpredictability” that should concern the Iranians, and Tehran may lash out more aggressively militarily as the economic pressure mounts.

Hello, this is Leonie Kidd coming to you from London.

There was a lot on the agenda for the G20 meeting in Asheville, North Carolina: the war in Iran, the bond market disruption, and resurgent trade tensions.

What did not seem to be clear, was the attendance of Russian Finance Minister Anton Siluanov, in a move that has left European officials in dismay.

Read on for more.

What you need to know today

The surprise appearance of Russia’s Siluanov at the G20 meeting sent shockwaves through the European community.

It marked his first in-person attendance of the summit since Russia’s invasion of Ukraine in 2022 and seemed to blindside the European attendees. Officials opposed appearing in the traditional G20 family photo with Russia, which was ultimately taken without Siluanov present.

U.S. Treasury Secretary Scott Bessent met with Siluanov on the sidelines of the event, and reportedly told the Russian official that no sanctions relief or new agreements with Moscow were possible, as long as the war in Ukraine continues.

Meanwhile, Indian Prime Minister Narendra Modi called on Russian President Vladimir Putin to cease his “endless war” in Ukraine, as the two leaders met at the Shanghai Cooperation Organization summit in Kyrgyzstan on Monday.

Strait back to strikes

Tensions with Iran also escalated over the weekend.

U.S. President Donald Trump threatened to hit Iran “hard” in an interview with Fox News on Monday, saying that “there will be a response” to Iran’s attacks on U.S. military bases in the region.

Meanwhile, another tanker was struck while transiting through the Strait of Hormuz on Monday.

Venezuela oil

The White House has announced that Venezuela has granted U.S.-backed North America Blue Energy Partners 100-year concessions for 17 oil fields in the country. Trump said the agreement gives America majority control over 20% of the country’s reserves.

Fast fashion fall

Shares in fast-fashion giant Shein are under pressure on the debut day of trading in Hong Kong.

The IPO values Shein at around $26.5 billion, compared with its private market valuation of $100 billion in 2022.

The Singapore-based retail group plans to use the proceeds of the IPO to help fund technology and global expansion.

Anthony Scaramucci on failure, ego and 11 days in the White House

Anthony Scaramucci’s career has included high-profile successes and setbacks.

In this episode of “Executive Decisions,” the SkyBridge Capital founder reflects on leaving Goldman Sachs to build his own business, why insecurity led him into the wrong job early in his career and the pride and ego that influenced his decision to join the Trump administration.

After being fired from the White House after just 11 days, Scaramucci was advised to disappear from public life. Instead, he chose to face his critics — a decision he says became part of a wider reckoning with his mistakes, his relationships and himself.
