RTX off, AI on: Jensen says we'll see fully AI-generated games in 5-10 years​

News

By Jarred Walton

published 2 days ago

GPU inception, with graphics cores processing AI workloads to generate graphics again.

Jensen at GTC 2024

The Nvidia GPU Technology Conference this week has provided some exciting news, including the reveal of Nvidia's next-generation Blackwell AI GPU, the B200. CEO Jensen held a Q&A session with the press later in the conference to field additional questions and provide further insights into where he sees things headed. One of the questions concerned the potential for AI-generated games, which Jensen says he expects to see within five to ten years. I'm paraphrasing here, but the essence of the question was: When do you think we could see fully AI-generated games?

The answer might surprise some, and represents something of an inception point for GPUs. Graphics Processing Units have been used to render games via rasterization for decades now, and more recently they've added ray tracing hardware to try to improve the visual fidelity. But AI-focused GPUs have now put all of the number-crunching power to a different task, creating ever larger and more powerful neural networks to generate content — tools like Stable Diffusion, Chat-GPT, Chat With RTX (now rebranded as ChatRTX, incidentally), Sora video generation, and more.

Jensen foresees a future in which GPU-powered AI tools could come full circle and put all that processing power to use in generating computer graphics again. But note the wording: generating graphics rather than rendering. And he thinks that an AI-generated gaming future could arrive within the next ten years, with early attempts potentially showing up within five years.



Granted, the amount of computational power behind Sora, both for training and generating minute-long video clips, is currently far beyond anything we'll see in a desktop PC within the next decade. There are tens of thousands of GPUs used by OpenAI for tools like Sora, so even if desktop GPU performance doubled every generation, we'd still only be looking at the computational equivalent of perhaps 32 RTX 4090 GPUs in our desktops a decade from now.

I don't think anyone is going to type in a simple prompt like, "Create an action-RPG pirate game with realistic graphics," and instantly get a fully playable and enjoyable game on their own PC within ten years, or perhaps even twenty years. But by the same token, we've already seen AI generate images, sound, 3D models, video, and code, and the quality of the generated content continues to improve with every iteration of the models. Ten years from now, it's easy to imagine AI-powered tools that can create models, levels, code, stories, and other assets in a matter of minutes. Push the initial computation up to cloud computing, and the on-the-fly generation of games doesn't feel nearly as out of reach.

I think with almost almost everything in technology, the S curve is not longer than a decade once it becomes true, once it becomes practical and better.

Jensen Huang

Here's the actual question and answer, edited for clarity. (We didn't catch the name of whoever asked the question, sorry.):

"How far do you think we are in this world where every pixel is generated at real-time frame rates? And what is your vision for gaming and non-gaming experiences in that new paradigm?"

Jensen: "I think with almost almost everything in technology, the S curve is not longer than a decade once it becomes true, once it becomes practical and better. And, of course, ChatGPT is not only practical; in most cases, it's better. I think it's less than ten years away. In ten year's time you're at the other end of that S curve. In five years from now, you're probably right in the middle where everything is changing in real-time, and everybody's going, 'Oh, look at that, this is happening.' And so you just got to decide, are we two years into it, into that ten years? Probably, we're probably already two years into it. And so I would say that within the next five to ten years, somewhere in between, it's largely the case."

In the interim, Nvidia and others are exploring AI-powered NPCs and new ways of interacting with game worlds. These currently feel stilted and artificial, at least the ones I've tried, but they also feel like something that could greatly enhance gaming worlds with only a moderate amount of effort. Ubisoft Neo, as an example, was just shown at this year's Game Developers Conference, and we could see many indie games within the next year that include AI-powered NPCs. Nvidia has been talking about ACE (Avatar Cloud Engine) for a couple of years now, and it continues to improve each time it gets demonstrated.

There are also plenty of examples of people creating games already with a relatively minimal effort — not good games, necessarily, but again, this is using version 1.0 tools. Even a lousy game created by AI in less than 10 minutes is a lot more than most people could manage on their own, and iterating on ideas to create better games can happen far more quickly. As Jensen also noted in the Q&A session, AI is democratizing access to writing code — you no longer need to go to years of school to be able to write code and scripts.

So will we eventually have DLSS 10 creating neurally rendered games in the future? The name might change, but the vastly increased use of AI tools to help create content is already happening. Whether that will eventually result in better games remains to be seen.

NHS AI test spots tiny cancers missed by doctors​

2 days ago

By Zoe Kleinman, Technology editor


_132974214_mediaitem132974213.jpg.webp
BBC
AI tool Mia circles two areas of concern on a mammogram scan

An AI tool tested by the NHS successfully identified tiny signs of breast cancer in 11 women which had been missed by human doctors.

The tool, called Mia, was piloted alongside NHS clinicians and analysed the mammograms of over 10,000 women.

Most of them were cancer-free, but it successfully flagged all of those with symptoms, as well as an extra 11 the doctors did not identify.

At their earliest stages, cancers can be extremely small and hard to spot.

The BBC saw Mia in action at NHS Grampian, where we were shown tumours that were practically invisible to the human eye. But, depending on their type, they can grow and spread rapidly.

Barbara was one of the 11 patients whose cancer was flagged by Mia but had not been spotted on her scan when it was studied by the hospital radiologists.

_132973665_ca85e0c2-e68f-4f0c-8d5c-8079047b86ad.jpg.webp

Barbara had her tumour caught early by AI

Because her 6mm tumour was caught so early she had an operation but only needed five days of radiotherapy. Breast cancer patients with tumours which are smaller than 15mm when discovered have a 90% survival rate over the following five years.

Barbara said she was pleased the treatment was much less invasive than that of her sister and mother, who had previously also battled the disease.

She told me she met a relative who expressed sympathy that Barbara had "the Big C".

"I said, 'it's not a big C, it's a very little one'," she said.

Without the AI tool's assistance, Barbara's cancer would potentially not have been spotted until her next routine mammogram three years later. She had not experienced any noticeable symptoms.

Because it works instantly, tools like Mia also have the potential to reduce the waiting time for results from 14 days down to three, claims its developer Kheiron.

None of the cases in the trial were analysed by Mia alone - each had a human review as well. Currently two radiologists look at each individual scan, but the hope is that one of them could one day be replaced by the tool, effectively halving the workload for each pair.

Of the 10,889 women who participated in the trial, only 81 did not want the AI tool to review their scans, said Dr Gerald Lip, clinical director of breast screening in the north east of Scotland and the doctor who led the project.

AI tools are generally pretty good at spotting symptoms of a specific disease, if they are trained on enough data to enable them to be identified. This means feeding the programme with as many different anonymised images of those symptoms as possible, from as diverse a range of people as possible.

Getting hold of this data can be difficult because of patient confidentiality and privacy concerns.

_132974029_9b90dba9-98fd-44f0-ae1c-cac0e54ad03b.jpg.webp

Sarah Kerruish, Chief Strategy Officer of Kheiron Medical

Sarah Kerruish, Chief Strategy Officer of Kheiron Medical, said it took six years to build and train Mia, which is run on cloud computing power from Microsoft, and it was trained on "millions" of mammograms from "women all over the world".

"I think the most important thing I've learned is that when you're developing AI for a healthcare situation, you have to build in inclusivity from day one," she said.

Breast cancer doctors look at around 5,000 breast scans per year on average, and can view 100 in a single session.

"There is an element of fatigue," said Dr Lip.

"You get disruptions, someone's coming in, someone's chatting in the background. There are lots of things that can probably throw you off your regular routine as well. And in those days when you have been distracted, you go, 'how on earth did I miss that?' It does happen."

_132973667_77c882f1-a1ec-44ff-a81f-f9f919d850bf.jpg.webp

Dr Gerald Lip ran the evaluation of the AI tool at NHS Grampian

I asked him whether he was worried that tools like Mia might one day take away his job altogether.

He said he believed the tech could one day free him up to spend more time with patients.

"I see Mia as a friend and an augmentation to my practice," Dr Lip said.

Mia isn't perfect. It had no access to any patient history so, for example, it would flag cysts which had already been identified by previous scans and designated harmless.

Also, because of current health regulation, the machine learning element of the AI tool was disabled - so it could not learn on the job, and evolve during its use. Every time it was updated it had to undergo a new review.

The Mia trial is just one early test, by one product in one location. The University of Aberdeen independently validated the research, but the results of the evaluation have not yet been peer reviewed. The Royal College of Radiologists say the tech has potential.

"These results are encouraging and help to highlight the exciting potential AI presents for diagnostics. There is no question that real-life clinical radiologists are essential and irreplaceable, but a clinical radiologist using insights from validated AI tools will increasingly be a formidable force in patient care." said Dr Katharine Halliday, President of the Royal College of Radiologists.

Dr Julie Sharp, head of health information at Cancer Research UK said the increasing number of cancer cases diagnosed each year meant technological innovation would be "vital" to help improve NHS services and reduce pressure on its staff.

"More research will be needed to find the best ways to use this technology to improve outcomes for cancer patients," she added.

There are other healthcare-related AI trials going on around the UK, including an AI tool by a firm called Presymptom Health which is analysing blood samples looking for signs of sepsis before symptoms emerge - but many are still in early stages without published results.

New bipartisan bill would require labeling of AI-generated videos and audio​

Politics Mar 21, 2024 5:32 PM EDT

WASHINGTON (AP) — Bipartisan legislation introduced in the House Thursday would require the identification and labeling of online images, videos and audio generated using artificial intelligence, the latest effort to rein in rapidly developing technologies that, if misused, could easily deceive and mislead.

So-called deepfakes created by artificial intelligence can be hard or even impossible to tell from the real thing. AI has already been used to mimic President Joe Biden’s voice, exploit the likenesses of celebrities and impersonate world leaders, prompting fears it could lead to greater misinformation, sexual exploitation, consumer scams and a widespread loss of trust.

Key provisions in the legislation would require AI developers to identify content created using their products with digital watermarks or metadata, similar to how photo metadata records the location, time and settings of a picture. Online platforms like TikTok, YouTube or Facebook would then be required to label the content in a way that would notify users. Final details of the proposed rules would be crafted by the National Institute of Standards and Technology, a small agency within the U.S. Department of Commerce.

Violators of the proposed rule would be subject to civil lawsuits.

WATCH: Why more people are turning to artificial intelligence for companionship

“We’ve seen so many examples already, whether it’s voice manipulation or a video deepfake. I think the American people deserve to know whether something is a deepfake or not,” said Rep. Anna Eshoo, a Democrat who represents part of California’s Silicon Valley. Eshoo co-sponsored the bill with Republican Rep. Neal Dunn of Florida. “To me, the whole issue of deepfakes stands out like a sore thumb. It needs to be addressed, and in my view the sooner we do it the better.”

If passed, the bill would complement voluntary commitments by tech companies as well as an executive order on AI signed by Biden last fall that directed NIST and other federal agencies to set guidelines for AI products. That order also required AI developers to submit information about their product’s risks.

Eshoo’s bill is one of a few proposals put forward to address concerns about the risks posed by AI, worries shared by members of both parties. Many say they support regulation that would protect citizens while also ensuring that a rapidly growing field can continue to develop in ways that benefit a long list of industries like health care and education.

The bill will now be considered by lawmakers, who likely won’t be able to pass any meaningful rules for AI in time for them to take effect before the 2024 election.

“The rise of innovation in the world of artificial intelligence is exciting; however, it has potential to do some major harm if left in the wrong hands,” Dunn said in a statement announcing the legislation. Requiring the identification of deepfakes, he said, is a “simple safeguard” that would benefit consumers, children and national security.

Several organizations that have advocated for greater safeguards on AI said the bill introduced Thursday represented progress. So did some AI developers, like Margaret Mitchell, chief AI ethics scientist at Hugging Face, which has created a ChatGPT rival called Bloom. Mitchell said the bill’s focus on embedding identifiers in AI content — known as watermarking — will “help the public gain control over the role of generated content in our society.”

“We are entering a world where it is becoming unclear which content is created by AI systems, and impossible to know where different AI-generated content came from,” she said.

If you really want to explore the alien the intelligence that is LLM's, you peek inside the latent space.

Take the vector for "Mother" and remove from it the concept of "Mom", you get these wild, ethereal, beautiful sentences, like: THE TERMINATION OF NEARLY ALL SACRED PLACES

2/8
What if you do the reverse? Take the concept of Mom, and remove "Mother", what are you left with?

"I'm a business man!"
"IT'S A PHONEBOOK"

Ok haha, this is just kinda silly right? no I think this is capturing something real about our universe/language/society

Here's a very similar result from a different model (this one isn't an LLM). Mom minus other gives you "goofy". (other way around gives "maternal"/"mother")

My theory from playing with this is that the concept of Mother is "heavier" than Mom. That Mother encompasses Mom. That when you take Mother out of Mom, you're left with just the unique parts of Mom that are NOT in Mother (which are lightheartedness, but not maternal love itself)

7/8
I didn't expect removing Mom from Mother would be so grim. It isn't grim in the much smaller word vectors NLP model. It's grim in the LLM

I think it's worth taking a closer look. It's not _just_ grim. What's common amongst these? Extreme sacrifice? subjugation? Here's more

Generative artificial intelligence model can easily design billions of novel antibiotics​

Mar 22 2024 McMaster University

Researchers at McMaster University and Stanford University have invented a new generative artificial intelligence model which can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory.

The worldwide spread of drug-resistant bacteria has created an urgent need for new antibiotics, but even modern AI methods are limited at isolating promising chemical compounds, especially when researchers must also find ways to manufacture these new AI-guided drugs and test them in the lab.

In a new study, published today in the journal Nature Machine Intelligence, researchers report they have developed a new generative AI model called SyntheMol, which can design new antibiotics to stop the spread of Acinetobacter baumannii, which the World Health Organization has identified as one of the world's most dangerous antibiotic-resistant bacteria.

Notoriously difficult to eradicate, A. baumannii can cause pneumonia, meningitis and infect wounds, all of which can lead to death. Researchers say few treatment options remain.

"Antibiotics are a unique medicine. As soon as we begin to employ them in the clinic, we're starting a timer before the drugs become ineffective, because bacteria evolve quickly to resist them," says Jonathan Stokes, lead author on the paper and an assistant professor in McMaster's Department of Biomedicine & Biochemistry, who conducted the work with James Zou, an associate professor of biomedical data science at Stanford University.

"We need a robust pipeline of antibiotics and we need to discover them quickly and inexpensively. That's where the artificial intelligence plays a crucial role," he says.

Researchers developed the generative model to access tens of billions of promising molecules quickly and cheaply.

They drew from a library of 132,000 molecular fragments, which fit together like Lego pieces but are all very different in nature. They then cross-referenced these molecular fragments with a set of 13 chemical reactions, enabling them to identify 30 billion two-way combinations of fragments to design new molecules with the most promising antibacterial properties.

Each of the molecules designed by this model was in turn fed through another AI model trained to predict toxicity. The process yielded six molecules which display potent antibacterial activity against A. baumannii and are also non-toxic.

Synthemol not only designs novel molecules that are promising drug candidates, but it also generates the recipe for how to make each new molecule. Generating such recipes is a new approach and a game changer because chemists do not know how to make AI-designed molecules."
