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.»

Pope Francis’ Funeral: How to Stream Live or Watch the Replay

Here’s how to stream the pope’s funeral very early Saturday, and what you can expect to see during the service.

After a week of global mourning for Pope Francis, who died on Monday at age 88, the pope’s funeral will be celebrated on Saturday . Francis’ funeral will be held Saturday at 10 a.m. local time at St. Peter’s Square in Vatican City (which is very, very early if you’re tuning in from the US or Canada), and he will be laid to rest at the Papal Basilica of St. Mary Major in Rome. 

The Vatican will be livestreaming the papal funeral and procession, though not the burial, on its YouTube channel as it happens. The funeral will also be televised live on CBS, NBC, ABC and Fox, as well as on streaming services like Disney Plus, Hulu, Peacock and Paramount Plus. Due to the time difference, it seems likely that many interested North American viewers will catch it when it’s replayed later on Saturday. Numerous networks will rebroadcast the service later that day.

If you choose to stay up, or get up early, here’s when the live broadcast of the pope’s funeral will air in your time zone in the continental US on April 26:

  • ET: 4 a.m.
  • CT: 3 a.m.
  • MT: 2 a.m.
  • PT: 1 a.m.

The papacy of Pope Francis was notable for the progressive reforms he brought to the Roman Catholic Church. He appointed more than half of the current College of Cardinals and attempted to foster more positive attitudes toward members of the LGBT community and migrants worldwide.

What to expect from the funeral 

The funeral will follow many rituals, though not all traditional protocols will be followed. Most popes are buried in St. Peter’s Basilica or its grottoes, but the AP reports Francis chose the St. Mary Major Basilica to reflect his veneration of an icon of the Virgin Mary that is located there, the Salus Populi Romani (Salvation of the People of Rome).

His funeral will be less elaborate than those of other popes per his own wishes. Francis simplified papal funeral rites last year, permitting his burial outside the Vatican, and emphasizing his role as a bishop rather than as pope (the pope is also the Bishop of Rome).

Previous popes were buried in three coffins: one of cypress, one of lead and one of oak. Francis requested to be buried in a single wooden, zinc-lined coffin and not to be placed in an elevated bier as other popes were.

The coffin will be taken from St Peter’s Basilica and placed on a dais in St Peter’s Square, where Cardinal Giovanni Battista Re will lead the service. After the service, the coffin will return to St Peter’s Basilica before it is carried across the River Tiber and to the Papal Basilica of Saint Mary Major for burial. The ceremony is estimated to end around 2 p.m. local time, or four hours after it begins.

Pope Francis’ funeral Mass will be the first of nine Masses held daily at St. Peter’s until May 4. This is an ancient tradition of the Catholic Church that observes nine days of consecutive mourning. According to Vatican News, a different group of mourners will participate each day, though the Eucharistic celebrations are open to everyone.

Who will attend Pope Francis’ funeral?

Hundreds of people, including world leaders and royals, are expected to attend Pope Francis’ funeral. 

US president Donald Trump confirmed on his Truth Social Platform that he and first lady Melania Trump will be at the funeral. This will be Trump’s first foreign trip in his second term. He is expected to have a seat in the third row, though the Vatican has yet to release an official seating chart. It is tradition for the first row of seats to go to Catholic royalty, and the second row to non-Catholic royals.

Prince William, who is attending on behalf of King Charles, will sit in the second row, which is reserved for non-Catholic royals. Former president Joe Biden and first lady Jill Biden, devout Catholics, will also attend the funeral.

Conclave: What happens next to choose the new pope

After Pope Francis’ funeral, the cardinals of the Roman Catholic Church will vote on his successor in an assembly of cardinals known as a conclave.

There are many matters for the cardinals to settle before the conclave begins, but once it does, it can take days or even weeks to conclude. Two-thirds of the cardinals’ votes are required to elect the next pope. The conclave occurs behind closed doors and the vote tally is never made public.

Look for the white smoke

The ballots are burned after each round, and chemicals are added to the flames to produce black smoke if there’s no majority. When a new pope has been selected, the chemicals will be added to the flames so they produce white smoke. Crowds gather in St. Peter’s Square to watch for the results.

If you’re fascinated by the process, you can watch a dramatized version of the events in 2024 film Conclave.

In the movie, Ralph Fiennes stars as Cardinal Thomas Lawrence, who spearheads the election of the next pope while investigating rumors about potential candidates. The film is based on the 2016 novel by Robert Harris and is completely fictional — though it does represent some of the events of how actual papal conclaves take place. In March, the film won the Academy Award for best adapted screenplay.

You can stream Conclave on Amazon Prime Video, or rent it for $6 on Apple TV, Fandango at Home, YouTube or Google Play Movies.
