How ChatGPT Could Take Microsoft’s Search Engine Bing Into the Future

Have you ever found yourself trawling through endless pages of results on a search engine to find the answer to a complex question? Say you want to find out if a vegetarian diet is suitable for your dog. Your research journey might begin by hopping onto Google and typing “is a veg diet good for dogs” into the search box and then having to make sense of the legion of generated links. By the time you find an answer, you’ve sunk way more time than you’d budgeted into poring through articles, reports and their sources. 

In the not-so-distant future, finding the answer to a complex question might not be such a tedious, mind-numbing process. Microsoft is reportedly integrating the AI tech that underlies ChatGPT into its Bing search engine in a move that could transform search as we know it. More specifically, Bing might have the potential to serve up a search experience that’s superior to Google, according to AI researchers, and potentially usurp the search giant’s decades-long dominance.

“ChatGPT is the first new technology in more than a decade that may really transform search and that could, at least in principle, upend Google’s market dominance,” said Anton Korinek, an AI researcher and professor of economics, at the University of Virginia. “What the technology does is that it allows consumers to interact with their computer in a much more natural and conversational form than traditional search.”

At this point, we don’t know what Bing’s AI-driven search results might look like exactly. Microsoft declined to comment for this story. However, AI researchers expect a meaningful departure from the status quo in terms of how a search engine presents an answer and how users interact with it. After all, ChatGPT is not designed to browse the internet for information (like a search engine). Instead, the chatbot uses information studied from vast swaths of training data to generate a response.

“ChatGPT can answer its users with a single clear response compared to the myriads of links of traditional search engines. It also has capabilities that are far beyond traditional search engines, like [the ability] to generate new text, explain concepts, have a back-and-forth conversation between the user and the system, and so on,” said Korinek. “People still find emergent capabilities that even the creators of ChatGPT were not aware that the system had.”

Microsoft announced plans on Jan. 23 to invest more resources into OpenAI, the creator of ChatGPT, to the tune of $10 billion. The deal would help keep both companies at the cutting edge of what’s known as generative AI, a tech used in ChatGPT that can learn from copious amounts of data to create virtually any content format (text, images, music and so on) simply from a text prompt. 

Search is just one in a suite of consumer-facing products in Microsoft’s stable that could potentially change meaningfully for customers in the coming years. According to a report by The Information, the Seattle-based tech giant also has plans to integrate ChatGPT’s AI tech into long-established products like Word, PowerPoint and Outlook in an endeavor that could change how more than a billion people work and accomplish daily tasks. For instance, integrating it into Outlook could mean simply prompting the email application to write a message about a specific topic. 

“Microsoft will deploy OpenAI’s models across our consumer and enterprise products and introduce new categories of digital experiences built on OpenAI’s technology,” the company said in a press release announcing the expanded partnership.

Conversational search

For its part, Google and its cutting-edge subunit DeepMind have been working on similar systems for years. The search giant chose not to release them to the public, though, in part over concerns about unethical behavior and how chat systems sometimes break social norms. For instance, in 2016 Microsoft created a chatbot called Tay that it was forced to take offline after it spewed out hate speech. Even ChatGPT, which has rules to create positive and friendly content, can be manipulated into producing upsetting responses using the right prompts.

However, DeepMind CEO Demis Hassabis said in an interview with Time this month that his company is considering its own chatbot, called Sparrow, for a “private beta” sometime in 2023. Google also plans to demonstrate a version of its search engine with chatbot features as early as this year, according to a New York Times report citing sources familiar with the matter. 

It’s no secret that Google search has become more conversational in general over the years. The company has made progress in this area with the Google assistant and with knowledge panels in search, and for years has pitched conversation as the future of search, demoing its AI systems LaMDA and MUM at its 2021 I/O developer conference. 

Leveraging OpenAI’s artificial intelligence seems to be how Microsoft is attempting to edge out Google at its own game. In the wake of ChatGPT’s release, Google management issued a “code red,” according to The New York Times. The report said internal teams had been reassigned to kickstart work on AI between now and an expected company conference in May. 

Still, Google’s search engine today remains the undisputed market leader as it has for decades, commanding 84{4224f0a76978c4d6828175c7edfc499fc862aa95a2f708cd5006c57745b2aaca} of global search market share, compared to Bing’s 9{4224f0a76978c4d6828175c7edfc499fc862aa95a2f708cd5006c57745b2aaca} (although it has grown in recent years) in 2022, according to Statista.  

Google didn’t immediately respond to a request for comment on this story.

How smart is ChatGPT?

As you’ve probably heard by now, ChatGPT is a sophisticated chatbot that went viral globally after its consumer release in late November as a free online tool accessible to anyone with an internet connection. The AI-powered chatbot made headlines thanks in part to its ability to churn out delightful poetry, generate meal plans and provide authoritative answers to complex questions within seconds after being prompted. The tech underlying it isn’t exactly brand new, but no chatbot had yet managed to capture mainstream fascination in the way that ChatGPT did. That’s largely because OpenAI built a snazzy user experience around the GPT-3.5 language model, and that’s the phenomenon we know as ChatGPT. 

GPT-3.5 is an improved version of GPT-3, which debuted in 2020 and which learned from vast tracts of data and code to help it achieve its abilities. According to researchers at Stanford University, GPT-3 was trained on 570 gigabytes of text and has 175 billion parameters. (Google’s Dale Markowitz, meanwhile, put it at 45 terabytes of text data, “including almost all of the public web.”) For comparison, its predecessor, GPT-2, was over 100 times smaller, at 1.5 billion parameters. 

“This increase in scale drastically changes the behavior of the model — GPT-3 is able to perform tasks it was not explicitly trained on, like translating sentences from English to French, with few to no training examples. This behavior was mostly absent in GPT-2,” researchers from Stanford‘s Institute for Human-Centered Artificial Intelligence wrote in a 2021 post.

“The current version of ChatGPT probably already knows more about the world than any individual human, and it can present that knowledge in digestible form,” said Korinek.

For all the promise ChatGPT holds, there are nearly as many limitations. Critics of ChatGPT say it’s not always clear where the chatbot is pulling information from, which can make it difficult for people to trust the results. Skeptics also point out that ChatGPT will always remain undermined by the imperfect nature of the data it was trained on, including biased information or misinformation. 

OpenAI has acknowledged the chatbot’s weaknesses in its current form. CEO Sam Altman said in a December post on Twitter that the product struggles with “robustness and truthfulness” and that it would be “a mistake to be relying on it for anything important right now.”

But don’t look for the AI bandwagon to slow down.

“There will be a number of new systems like ChatGPT that will enter the market in 2023, and the main implication of the resulting competition is that consumers will have more choice and, hopefully, better products for consumers,” added Korinek.

GPT-4, which is under development, is reported to have 100 trillion parameters. But a release is not expected to take place until OpenAI is “confident we can [release] it safely and responsibly,” Altman said in an interview with StrictlyVC in early January. 

Altman also attempted to manage expectations of that fourth iteration of GPT, the sophisticated language model that underpins ChatGPT, saying “we don’t have AGI.” AGI stands for artificial general intelligence, or a technology with its own emergent intelligence as opposed to relying on the deep learning models currently used by OpenAI. It’s the kind of intelligence that has been dramatized in science fiction stories for more than a century and was popularized in recent years by the award-winning dystopian show Westworld. 

“I think [AGI] is sort of what is expected of us,” Altman said in the same interview, adding that GPT-4 is “going to disappoint” people who hold out that hope.

For his day job, Tobias Zwingmann is the managing partner of RAPYD.AI, a German consulting firm that helps clients make use of artificial intelligence. On the side, Zwingmann teaches online courses on AI.

Lately, Zwingmann has been generating lecture notes using ChatGPT, a new chatbot that’s quickly become the latest fad in tech. Zwingmann said he recently asked ChatGPT to explain the mechanisms and workings of a machine learning technology known as a DBSCAN, which is short for density-based spatial clustering of applications with noise, because he is too “lazy to write it all down.”

“I went up and said, ‘OK, tell me a detailed step by step of how the DBSCAN algorithm works,’ and it gave me that step by step,” Zwingmann said.

After a little bit of polishing and editing, Zwingmann said the lecture notes were in good shape.

“This took me like 30 minutes, and before that I would have spent the whole day,” Zwingmann said. “I can’t neglect that this has proven to be hugely beneficial.”

ChatGPT debuted in late November and has quickly turned into a viral sensation, with people tweeting questions, such as “Are NFTs dead,” and requests like, “Tell a funny joke about the tax risks of international remote work.” They include a screenshot of ChatGPT’s response, which often — but not always — makes sense.

The technology was developed by San Francisco-based OpenAI, a research company led by Sam Altman and backed by Microsoft, LinkedIn co-founder Reid Hoffman and Khosla Ventures. ChatGPT automatically generates text based on written prompts in a fashion that’s much more advanced and creative than the chatbots of Silicon Valley’s past.

In a year that’s turned into a dud for the technology sector, with mass layoffs, wrecked stock prices and crypto catastrophes dominating the headlines, ChatGPT has served as a reminder that innovation is still happening.

Tech layoffs double from October to November as DoorDash cuts headcount

Tech executives and venture capitalists have gushed about it on Twitter, some even comparing it to Apple’s debut of the iPhone in 2007. Five days after OpenAI released ChatGPT, Altman said that the chat research tool “crossed 1 million users!”

Back in 2016, tech giants like Facebook, Google and Microsoft were trumpeting digital assistants as the next evolution of human and computer interaction. They boasted of the potential for chatbots to order Uber rides, buy plane tickets and answer questions in a life-like manner.

Six years later, progress has been slow. The majority of chatbots that people interact with are still relatively primitive, only capable of answering rudimentary questions on corporate help desk pages or minimally helping frustrated customers understand why their cable bills are so high.

But with early ChatGPT adopters demonstrating the technology’s ability to carry a conversation through multiple queries in addition to generating software code, the world of so-called natural language processing appears to be entering a new phase.

It’s part of the larger trend. Tech investors are pouring billions of dollars in startups specializing in the field of generative AI, which refers to the ability of computers to automatically create text, videos, photos and other media using cutting-edge machine learning technologies.

Brendan Burke, an analyst at tech industry data firm PitchBook, said a number of early-stage investors have turned their attention from cryptocurrencies and related concepts like web3 to generative AI technologies.

“That’s a trend that is perceptible,” Burke said.

According to PitchBook, the top firms in the space are Khosla, David Sacks’ Craft Ventures, Sequoia, Entrepreneur First out of the U.K. and Lux Capital. Investors have also noticed on platforms like GitHub that many web3 developers have shifted their attention from NFTs and crypto projects to open-source generative AI initiatives, Burke said.

“I think that’s a sign of some of the rethinking that’s going on throughout the early-stage market,” Burke said.

What is ChatGPT?

ChatGPT is essentially a variant of OpenAI’s popular GPT-3.5 language-generation software that’s been designed to carry conversations with people. Some of its features include answering follow-up questions, challenging incorrect premises, rejecting inappropriate queries and even admitting its mistakes, according to an OpenAI summary of the language model.

ChatGPT was trained on an enormous amount of text data. It learned to recognize patterns that enable it to produce its own text mimicking various writing styles, said Bern Elliot, a vice president at Gartner. OpenAI doesn’t reveal what precise data was used for training ChatGPT, but the company says it generally crawled the web, used archived books and Wikipedia.

OpenAI declined to comment for this story.

Elliot said that for now ChatGPT is more of a way for OpenAI to gain publicity and to show what’s possible for large language models, as opposed to a useful piece of software for businesses to incorporate. While ChatGPT is free, OpenAI sells access to its underlying language and related AI models for businesses to use.

“ChatGPT, as currently conceived, is a parlor trick,” Elliot said. “It’s something that isn’t actually itself going to solve what people need, unless what they need is sort of a distraction.”

How bots are being deployed inside banks after a pandemic boom in fraud

However, Zwingmann isn’t alone in using ChatGPT for more advanced purposes.

Cai GoGwilt, the chief technology officer of digital contract management startup Ironclad, said his company is exploring how ChatGPT could be used to summarize changes to legal documents. The feature would be helpful for the startup’s legal clients, who routinely alter documents and then notify their colleagues after they made the changes, GoGwilt said.

GoGwilt said ChatGPT offers “more creative” responses compared to similar language models developed by big tech companies. Meta’s AI language tool, dubbed RoBERTa, seems more capable at categorizing and labeling text, GoGwilt said, adding that his company uses both GPT and RoBERTa to power certain features in its digital document software.

At legal research and data company LexisNexis, Min Chen, a vice president, said in an email that she and her team are just starting to test ChatGPT although they already use OpenAI’s GPT-3 software through Microsoft’s Azure cloud.

Chen said GPT-3 is more suitable for LexisNexis because it’s an enterprise product and can be customized. However, her team has been experimenting with ChatGPT and she said it sometimes generates “sensible answers” that are “very impressive.” Still, it has its flaws.

“I am afraid it’s not reliable enough as a decision-making tool for serious legal research,” Min said. “In some cases, ChatGPT will give a very verbose answer that seems to make sense, but the answer is not getting the facts right.”

There’s also the bias problem, which is true for many kinds of AI-powered software.

As Mozilla senior fellow Abeba Birhane shared on Twitter, ChatGPT produced song lyrics that implied women who wear lab coats are “probably just there to clean the floor,” whereas men wearing lab coats “probably got the knowledge and skills you’re looking for.”

Regarding ChatGPT’s limitations, OpenAI said in a blog post that while the firm is working to mitigate bias problems, the software “will sometimes respond to harmful instructions or exhibit biased behavior.”

Altman said in a tweet over the weekend that ChatGPT is “incredibly limited” and “it’s a mistake to be relying on it for anything important right now.”

Krishna Gade, CEO of AI model monitoring startup Fiddler, said ChatGPT and related language technologies could lead to big “disruptions in web search,” an area long dominated by Google.

Gade, who previously worked at Microsoft’s Bing search unit, said if ChatGPT’s popularity continues to grow along with other chat-based tools that answer questions, Google may have to update its core search technology to more prominently center on chat.

ChatGPT’s rising popularity shows there is a segment of the population that prefers getting information via question and answers as opposed to a typical search query.

Google parent Alphabet has plenty of AI talent and has helped develop some of the core AI technologies used to create systems like ChatGPT. The search engine is also a habit that’s very difficult to displace.  

As Zwingmann notes, Google still has a major advantage over ChatGPT.

“The way it works currently is people use ChatGPT and then go to Google to verify the results,” Zwingmann said, with a laugh.

Here’s what happened when we typed in, “Write me a news story about ChatGPT in the style of CNBC.”

As of December 13, 2022, ChatGPT, the new language processing AI from OpenAI, is making waves in the tech industry. The advanced model, which is trained to generate human-like text, is already being hailed as a game-changer for businesses that rely on natural language processing.

ChatGPT’s ability to understand and respond to a wide range of topics has been particularly impressive, with some even suggesting that it has the potential to revolutionize the way we interact with technology. Many experts believe that ChatGPT’s advanced capabilities will be a valuable asset for companies in fields such as customer service, online education, and market research.

One of the key advantages of ChatGPT is its ability to learn and adapt quickly to new information. This means that it can be trained to handle new topics and tasks without the need for extensive retraining. Additionally, ChatGPT is highly scalable, which makes it well-suited for use in large-scale applications.
So far, the response to ChatGPT has been overwhelmingly positive, with many praising its advanced capabilities and ease of use. It remains to be seen how ChatGPT will be used in the coming years, but it’s clear that it has the potential to be a major player in the world of natural language processing.

New technology may help inform brain stimulation — ScienceDaily

Brain stimulation, these as Deep mind stimulation (DBS), is a powerful way to deal with neurological and psychiatric diseases. Although it has presented therapeutic benefit for victims of Parkinson’s, Alzheimer’s, and dependancy for extra than a ten years, its fundamental neural mechanism is not nevertheless entirely comprehended.

Researchers at the Queensland Brain Institute (QBI) are now a person step closer to unravelling the thriller of brain exercise to greater have an understanding of this mechanism and possibly predict DBS outcomes.

The brain is a very complicated community of circuits organised hierarchically with large-ranging connections. Connections go in unique directions, forwards and backwards, and involving neurons that are both excitatory — the accelerators of a response — or inhibitory — the brakes modifying a reaction.

“Say you want to shift your hand — the moment that signal is initiated, we assume that the action that follows depends on the brain’s neural networks,” Affiliate Professor Kai-Hsiang Chuang explained.

“What we will not totally have an understanding of is how or when these structural and useful elements of the mind interact to ultimately lead to the result of relocating your hand.”

Purposeful MRI (fMRI) is the most common method applied to examine brain networks. fMRI tracks blood movement and oxygenation variations pursuing neural action, thus indirectly measuring the purposeful connections becoming fashioned, and supplying us an indication of wherever brain exercise is propagating.

Mind action, however, isn’t as straightforward as a signal travelling from spot to spot.

The group at the Chuang laboratory have designed a new ultrafast fMRI approach with a vastly elevated temporal resolution, enabling them to capture the dynamics of brain activity at a sub-second level.

Affiliate Professor Chuang stated the new method had led to much more comprehensive comprehending of how and when the brain’s structural and practical connections interact.

“The initial new discovery we built is that brain activity not only propagates by way of structural wiring but follows specified preferential circuits dependent on their excitatory and inhibitory neuronal distribution,” he explained.

“Communication in between mind areas of identical cell types results in being a lot more fluent, and the mind activity more powerful.”

The Chuang team tracked the mind exercise of mice the two whilst stimulated and at relaxation utilizing their ultrafast fMRI strategy. When the mind was stimulated, exercise adopted the structural wiring in the forward route — from A to B and then B to C. When the brain was at rest, exercise was more dependent on cell kind organisation and significantly less on structural wiring, propagating amongst C and B but not with A, if that is wherever the preferential circuit was.

This means that how information and facts is processed is basically dependent on your condition, wherever it was beforehand imagined that brain action functioned in the same way no matter if at rest or chaotic undertaking a process.

“The 2nd discovery we created was that the blood signal detected by fMRI could mirror the network organisation and cell form distribution,” Affiliate Professor Chuang claimed.

“These results have substantial implications for how mind framework shapes functionality, and how to predict exercise based mostly on the knowledge of this structure. Much more virtually, what we now know will effects the design and style of DBS and other mind stimulation techniques.

“The up coming measures are to function with clinicians versed in brain stimulation to figure out how we can utilise this information merged with human facts to assistance boost our understanding of DBS.”

This far more comprehensive knowledge could allow us to better forecast DBS success and likely improve its structure for superior therapeutic results.

This study was to start with printed in the Proceedings of the Nationwide Academy of Sciences (PNAS).

Transplanted hearts kept viable longer between donor and recipient, thanks to new technology

In early January previous yr, Alex Moroianu had her last typical working day.

Life was quite very good. She was doing work her 1st complete-time career as a management expert in Perth, while finishing off a study paper based mostly on her masters in astrophysics, finding out black holes and neutron stars.

She went out that night time with her boyfriend and some mates, dancing until eventually 3am. But the upcoming day she could scarcely walk, wracked with discomfort and nausea. It wasn’t just a hangover.

“From that day, it just by no means definitely stopped. It acquired worse and even worse, and we could not figure out why.”

Alex was in extreme coronary heart failure — a shock for somebody who’d been quite substantially wholesome right until that place.

A young woman smiling and posing by a colourful flowerbed on a sunny day
Even in late 2021, Alex felt as suit and balanced as ever, and no plan of what was to appear.(Supplied)

In healthcare facility, her physicians advised her the remaining aspect of her heart was working at a portion of what it ought to, and the right aspect wasn’t accomplishing a lot greater.

They despatched her house with medications and a daily life vest — a product she experienced to wear working day and night time that would shock her coronary heart if it began beating erratically.

She hardly ever had to go as a result of the shock of the defibrillator vest for the reason that she was only out of hospital for three weeks ahead of she went back again in to remain.

“The 1st working day I was in there, the health care provider came to me and he said, ‘We believe you have to have a heart transplant and we want you to get shown urgently as shortly as achievable,'” Alex states.

“It was quite terrifying. I bear in mind crying a whole lot.

“But by the conclude of the 7 days … I realised that a heart transplant was my very best chance at a excellent existence.”

Alex deteriorated promptly. But though she was a good candidate for transplantation — young and in any other case healthy — the months just retained ticking by without a coronary heart getting to be readily available.

“I begun having seriously afraid,” she says.

“Matters were being just obtaining even worse and worse for me and the coronary heart just wasn’t coming.”

The tyranny of length

This is the matter about living on the west coast of a huge, sparsely populated state like Australia.

A transplanted coronary heart commences to deteriorate as before long as it truly is eliminated from a donor’s entire body, transported on ice in the exact same kind of esky as you can purchase at your nearby hardware retail outlet.

Most of the populace — and by extension, most organs that can be donated — are on the east coastline.

And Perth, wherever Alex life, is usually just as well considerably away for an east coast donor coronary heart to very last till it can be transplanted.

A young woman in a hospital gown standing next to a hospital bed, hooked up to machines and making a V sign
As time passed, Alex’s situation, named dilated cardiomyopathy, got worse.(Provided)

The recent gold conventional of heart transplantation, the place the coronary heart is transported on ice in an esky, presents you about five hours to get the organ out of the donor and into the recipient, says John Fraser, an intensive care physician dependent at the Prince Charles and St Andrews hospitals in Brisbane.

“Four-and-a-fifty percent, 5 several hours, you believe, oh, which is really considerably,” Professor Fraser states.

“But you have obtained to recall the measurement of this broad brown land.

“So there is certainly a lot of lots of sites in Australia we cannot retrieve hearts from or we won’t be able to transplant because it is too long [to travel].”

But the tide is turning thanks to a study, co-led by Professor Fraser, called the Residing Heart Undertaking.

Retaining a heart beating en route

The Residing Coronary heart Challenge employs a new technology retaining hearts practical for lengthier.

It really is named hypothermic ex vivo perfusion (HEVP) and will involve putting the donor heart on a rig that keeps the organ at 8 degrees Celsius — like placing an ice pack on an injured muscle to end swelling — while pumping blood and a nutrient option by way of it.

So rather of being static and on ice, it receives oxygen and vitamins and minerals and has waste products eliminated, just as it would be if it was still beating inside of the body. 

The very first phase of a clinical trial into HEVP has just finished.

In distinction to the four- to 5-hour window of a ordinary transplant, Professor Fraser and his workforce confirmed they could sustain a coronary heart for as extensive as 8 hours and 47 minutes. Not by choice, but mainly because COVID restrictions slowed a transfer amongst states.

“There was a large kerfuffle having out of a person healthcare facility and across a border,” he remembers.

“In the past, if it wasn’t for that rig, that donor coronary heart would have not been usable and would have had to be disposed of, which would be a crying shame for the family of the donor, but even additional so for the recipient who’s prepped.”
