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.”

Iranian President Pezeshkian to head to New York for UN meeting as Trump warns of no-deal consequences

Trump threatened to destroy Iran’s economy or eliminate its leadership if Tehran doesn’t strike a deal, complicating efforts at diplomacy.

President Masoud Pezeshkian will lead an Iranian delegation at the United Nations General Assembly in New York on Tuesday, amid renewed hopes for a diplomatic solution to the Middle East conflict.

Pezeshkian will address the assembly and present Iran’s positions on “international developments,” according to the country’s semi-official Tasnim news agency, with a particular focus on its war with the U.S. and Israel.

He will also hold talks with the leaders of several countries on the sidelines of the event, which is scheduled to take place Sept. 22 to 26, and 28.

The Iranian delegation’s attendance at the UN has renewed hopes for a diplomatic solution to the war, lifting market sentiment on Monday, with stocks rising, oil prices easing and global bond yields falling sharply.

But U.S. President Donald Trump, who has said he would be open to meeting Pezeshkian during the assembly, has threatened to destroy Iran’s economy or eliminate its leadership if Tehran doesn’t strike a deal.

Trump told Fox News on Sunday that the only options on the table were “wiping Iran out,” or letting its economy “rot,” unless both sides reach a deal.

Separately, Iran’s military said that its intelligence suggested a new, large-scale strike being prepared by the U.S. and its allies, warning of “painful” retaliation across the Middle East. Regional countries backing such a strike would be treated as parties to the conflict, it said.

“If the U.S. makes any mistake against the Islamic Republic of Iran, all its positions and interests in the region will be targeted by sustained, effective and painful attacks,” the Khatam al-Anbia Central Headquarters of Iran said, according to Tasnim.

Houthi-Saudi conflict complicates diplomacy hopes

The U.S. State Department this weekend issued a security alert citing risks of unforeseen escalation in the Middle East, telling Americans to exercise more vigilance and be aware of possible flight cancellations and airspace closures.

The warnings came after Iran-backed Houthi militants claimed missile and drone attacks on Riyadh on Saturday, triggering the first air-raid alert in the Saudi capital since fighting escalated in July.

Saudi authorities said they intercepted and destroyed a ballistic missile and reported no casualties or damage. The Houthis also attempted to target civilians and infrastructure in several parts of the kingdom, Saudi-led coalition forces spokesperson Major-General Turki al-Maliki said on X on Saturday, though those attacks were thwarted by the country’s air defenses.

Oil prices have pulled back in recent days despite widening hostilities, as traders hope for a recovery in energy shipments from oil-rich Saudi Arabia.

Oil prices will remain high despite U.S. progress in moving oil through the Strait of Hormuz, a team of analysts at Eurasia Group said in a Saturday note. Any rebound in oil flows would not be enough to address the overall market deficit, they said, forecasting Brent prices to trade in a higher band of $90-110 per barrel through the rest of this year.

“Iran’s leadership will stick with resistance, even as they quarrel internally,” according to the consultancy firm, as Tehran seeks to use military proxies and tanker attacks to keep a chokehold on shipping flows, to pressure Washington into concessions.

Tehran has insisted that it would not reopen the Strait of Hormuz until Washington fulfills its commitment under the June memorandum, which called for lifting the naval blockade of Iranian ports, easing sanctions, unfreezing Iranian assets and ending U.S. military threats.

Iranian parliament speaker Mohammad Bagher Ghalibaf said Sunday that Iran must keep on fighting and negotiating, to push back its enemies, and only work on diplomacy when it has the upper hand on the battlefield.

U.S. crude oil drops below $100 a barrel as Trump signals willingness to negotiate with Iran

U.S. crude oil prices slipped back below $100 a barrel after President Trump signaled openness to talks with Iran and halted plans to bomb Yemen, while Middle East supply flows remained robust despite pipeline disruptions.

Crude oil prices declined for the fourth straight session on Monday after President Donald Trump reportedly decided against bombing Yemen for the time being and indicated he was open to diplomatic engagement with Iran.

U.S. West Texas Intermediate futures fell 2.7% to $97.59 per barrel by 7:48 a.m. ET, while Brent crude, the global benchmark, slipped 2.8% to $101 a barrel. The market has risen more than 11% so far this month.

Trump told Fox News he would likely be receptive to meeting Iranian President Masoud Pezeshkian at the United Nations General Assembly later this week.

According to The New York Times, the president has decided not to target the Iran‑aligned Houthi militants for now, despite requests from Saudi Arabia.

Meanwhile, crude shipments from the Middle East appear resilient after Saudi Arabia shut down its East‑West pipeline following attacks. JPMorgan analysts noted in a September 18 report that oil flows from the region remain surprisingly strong, averaging 17.1 million barrels per day over the past 10 days—about 6.1 million bpd below the 2025 average.

Potential supply disruptions persist. Trump told Fox that he is in a “deciding mode” and that “very big things” are expected soon regarding the U.S.–Iran conflict.

Prices are likely to stay closely linked to the pace of export normalization and diplomatic progress, said Daniel Takieddine, co‑founder and CEO of Sky Links Capital Group.

Any setback or renewed deterioration in shipping conditions would tighten the physical market and restore upward pressure on prices, Takieddine added.
