Kazu Gomi has an enormous view of the know-how world from his perch in Silicon Valley. And as president and CEO of NTT Analysis, a division of the massive Japanese telecommunications agency NTT, Gomi can management the R&D finances for a large chunk of the essential analysis that’s finished in Silicon Valley.
And maybe it’s no shock that Gomi is pouring some huge cash into AI for the enterprise to find new alternatives to benefit from the AI explosion. Final week, Gomi unveiled a brand new analysis effort to give attention to the physics of AI and properly as a chip design for an AI inference chip that may course of 4K video sooner. This comes on the heels of analysis tasks introduced final yr that might pave the best way for higher AI and extra vitality environment friendly information facilities.
I spoke with Gomi about this effort within the context of different issues large firms like Nvidia are doing. Bodily AI has turn into an enormous deal in 2025, with Nvidia main the cost to create artificial information to pretest self-driving vehicles and humanoid robotics to allow them to get to market sooner.
And constructing on a narrative that I first did in my first tech reporting job, Gomi mentioned the corporate is doing analysis on photonic computing as a technique to make AI computing much more vitality environment friendly.

A long time in the past, I toured Bell Labs and listened to the ambitions of Alan Huang as he sought to make an optical pc. Gomi’s workforce is attempting to do one thing related many years later. If they will pull it off, it might make information facilities function on so much much less energy, as mild doesn’t collide with different particles or generate friction the best way {that electrical} indicators do.
In the course of the occasion final week, I loved speaking to somewhat desk robotic referred to as Jibo that swiveled and “danced” and informed me my important indicators, like my coronary heart price, blood oxygen degree, blood strain, and even my ldl cholesterol — all by scanning my pores and skin to see the tiny palpitations and shade change because the blood moved via my cheeks. It additionally held a dialog with me through its AI chat functionality.
NTT has greater than 330,000 staff and $97 billion in annual income. NTT Analysis is a part of NTT, a worldwide know-how and enterprise options supplier with an annual R&D finances of $3.6 billion. About six years in the past it created an R&D division in Silicon Valley.
Right here’s an edited transcript of our interview.
Kazu Gomi is president and CEO of NTT Analysis.
VentureBeat: Do you are feeling like there’s a theme, a prevailing theme this yr for what you’re speaking about in comparison with final yr?
Kazu Gomi: There’s no secret. We’re extra AI-heavy. AI is entrance and middle. We talked about AI final yr as properly, however it’s extra vivid right now.
VentureBeat: I needed to listen to your opinion on what I absorbed out of CES, when Jensen Huang gave his keynote speech. He talked so much about artificial information and the way this was going to speed up bodily AI. As a result of you may check your self-driving vehicles with artificial information, or check humanoid robots, a lot extra testing may be finished reliably within the digital area. They get to market a lot sooner. Do you are feeling like this is sensible, that artificial information can result in this acceleration?
Gomi: For the robots, sure, 100%. The robots and all of the bodily issues, it makes a ton of sense. AI is influencing so many different issues as properly. Most likely not every little thing. Artificial information can’t change every little thing. However AI is impacting the best way companies run themselves. The authorized division could be changed by AI. The HR division is changed by AI. These sorts of issues. In these situations, I’m unsure how artificial information makes a distinction. It’s not making as large an impression as it could for issues like self-driving vehicles.
VentureBeat: It made me suppose that issues are going to come back so quick, issues like humanoid robots and self-driving vehicles, that we now have to determine whether or not we actually need them, and what we would like them for.
Gomi: That’s an enormous query. How do you take care of them? We’ve positively began speaking about it. How do you’re employed with them?
NTT Analysis president and CEO Kazu Gomi talks concerning the AI inference chip.
VentureBeat: How do you utilize them to enrich human employees, but additionally–I feel certainly one of your individuals talked about elevating the usual of dwelling [for humans, not for robots].
Gomi: Proper. For those who do it proper, completely. There are numerous good methods to work with them. There are actually dangerous situations which might be attainable as properly.
VentureBeat: If we noticed this a lot acceleration within the final yr or so, and we will count on artificial information will speed up it much more, what do you count on to occur two years from now?
Gomi: Not a lot on the artificial information per se, however right now, one of many press releases my workforce launched is about our new analysis group, referred to as Physics of AI. I’m wanting ahead to the outcomes coming from this workforce, in so many alternative methods. One of many fascinating ones is that–this humanoid factor comes close to to it. However proper now we don’t know–we take AI as a black field. We don’t know precisely what’s occurring contained in the field. That’s an issue. This workforce is wanting contained in the black field.
There are numerous potential advantages, however one of many intuitive ones is that if AI begins saying one thing incorrect, one thing biased, clearly it is advisable make corrections. Proper now we don’t have an excellent, efficient technique to appropriate it, besides to simply hold saying, “This is wrong, you should say this instead of that.” There’s analysis saying that information alone gained’t save us.
VentureBeat: Does it really feel such as you’re attempting to show a child one thing?
Gomi: Yeah, precisely. The fascinating splendid situation–with this Physics of AI, successfully what we will do, there’s a mapping of information. Ultimately AI is a pc program. It’s made up of neural connections, billions of neurons linked collectively. If there’s bias, it’s coming from a specific connection between neurons. If we will discover that, we will finally cut back bias by reducing these connections. That’s the best-case situation. Everyone knows that issues aren’t that straightforward. However the workforce might be able to inform that in the event you reduce these neurons, you may have the ability to cut back bias 80% of the time, or 60%. I hope that this workforce can attain one thing like that. Even 10% remains to be good.
VentureBeat: There was the AI inference chip. Are you attempting to outdo Nvidia? It looks as if that will be very onerous to do.
NTT Analysis’s AI inference chip.
Gomi: With that specific challenge, no, that’s not what we’re doing. And sure, it’s very onerous to do. Evaluating that chip to Nvidia, it’s apples and oranges. Nvidia’s GPU is extra of a general-purpose AI chip. It may well energy chat bots or autonomous vehicles. You are able to do all types of AI with it. This one which we launched yesterday is just good for video and pictures, object detection and so forth. You’re not going to create a chat bot with it.
VentureBeat: Did it seem to be there was a chance to go after? Was one thing probably not working in that space?
Gomi: The quick reply is sure. Once more, this chip is unquestionably personalized for video and picture processing. The bottom line is that with out lowering the decision of the bottom picture, we will do inference. Excessive decision, 4K photos, you should use that for inference. The profit is that–take the case of a surveillance digital camera. Possibly it’s 500 meters away from the item you wish to take a look at. With 4K video you may see that object fairly properly. However with typical know-how, due to processing energy, you must cut back the decision. Possibly you might inform this was a bottle, however you couldn’t learn something on it. Possibly you might zoom in, however you then lose different data from the world round it. You are able to do extra with that surveillance digital camera utilizing this know-how. Increased decision is the profit.

VentureBeat: This could be unrelated, however I used to be involved in Nvidia’s graphics chips, the place they had been utilizing DLSS, utilizing AI to foretell the following pixel it is advisable draw. That prediction works so properly that it obtained eight instances sooner on this era. The general efficiency is now one thing like–out of 30 frames, AI may precisely predict 29 of them. Are you doing one thing related right here?
Gomi: One thing associated to that–the explanation we’re engaged on this, we had a challenge that’s the precursor to this know-how. We spent numerous vitality and sources up to now on video codec applied sciences. We offered an early MPEG decoder for professionals, for TV station-grade cameras and issues like that. We had that base know-how. Inside this base know-how, one thing just like what you’re speaking about–there’s a little bit of object recognition occurring within the present MPEG. Between the frames, it predicts that an object is transferring from one body to the following by a lot. That’s a part of the codec know-how. Object recognition makes that occur, these predictions. That algorithm, to some extent, is used on this inference chip.
VentureBeat: One thing else Jensen was saying that was fascinating–we had an structure for computing, retrieval-based computing, the place you go right into a database, fetch a solution, and are available again. Whereas with AI we now have the chance for reason-based computing. AI figures out the reply with out having to look via all this information. It may well say, “I know what the answer is,” as a substitute of retrieving the reply. It might be a distinct type of computing than what we’re used to. Do you suppose that can be an enormous change?
Gomi: I feel so. A whole lot of AI analysis is happening. What you mentioned is feasible as a result of AI has “knowledge.” As a result of you could have that information, you don’t should go retrieve information.
NTT researcher talks about robotic canine and drones.
VentureBeat: As a result of I do know one thing, I don’t should go to the library and look it up in a e-book.
Gomi: Precisely. I do know that such and such occasion occurred in 1868, as a result of I memorized that. You might look it up in a e-book or a database, but when you realize that, you could have that information. It’s an fascinating a part of AI. Because it turns into extra clever and acquires extra information, it doesn’t have to return to the database every time.
VentureBeat: Do you could have any specific favourite tasks occurring proper now?
Gomi: A pair. One factor I wish to spotlight, maybe, if I might choose one–you’re wanting intently at Nvidia and people gamers. We’re placing numerous give attention to photonics know-how. We’re involved in photonics in a few other ways. While you take a look at AI infrastructure–you realize all of the tales. We’ve created so many GPU clusters. They’re all interconnected. The platform is big. It requires a lot vitality. We’re working out of electrical energy. We’re overheating the planet. This isn’t good.
We wish to handle this challenge with some totally different tips. One in every of them is utilizing photonics know-how. There are a few other ways. First off, the place is the bottleneck within the present AI platform? In the course of the panel right now, one of many panelists talked about this. While you take a look at GPUs, on common, 50% of the time a GPU is idle. There’s a lot information transport occurring between processors and reminiscence. The reminiscence and that communication line is a bottleneck. The GPU is ready for the info to be fetched and ready to put in writing outcomes to reminiscence. This occurs so many instances.
One thought is utilizing optics to make these communication traces a lot sooner. That’s one factor. By utilizing optics, making it sooner is one profit. One other profit is that relating to sooner clock speeds, optics is far more energy-efficient. Third, this includes numerous engineering element, however with optics you may go additional. You’ll be able to go this far, and even a few ft away. Rack configuration generally is a lot extra versatile and fewer dense. The cooling necessities are eased.
VentureBeat: Proper now you’re extra like information middle to information middle. Right here, are we speaking about processor to reminiscence?
NTT Improve exhibits off R&D tasks at NTT Analysis.
Gomi: Yeah, precisely. That is the evolution. Proper now it’s between information facilities. The subsequent part is between the racks, between the servers. After that’s throughout the server, between the boards. After which throughout the board, between the chips. Finally throughout the chip, between a few totally different processing models within the core, the reminiscence cache. That’s the evolution. Nvidia has additionally launched some packaging that’s alongside the traces of this phased method.
VentureBeat: I began masking know-how round 1988, out in Dallas. I went to go to Bell Labs. On the time they had been doing photonic computing analysis. They made numerous progress, however it’s nonetheless not fairly right here, even now. It’s spanned my entire profession masking know-how. What’s the problem, or the issue?
Gomi: The situation I simply talked about hasn’t touched the processing unit itself, or the reminiscence itself. Solely the connection between the 2 parts, making that sooner. Clearly the following step is we now have to do one thing with the processing unit and the reminiscence itself.
VentureBeat: Extra like an optical pc?
Gomi: Sure, an actual optical pc. We’re attempting to do this. The factor is–it sounds such as you’ve adopted this subject for some time. However right here’s a little bit of the evolution, so to talk. Again within the day, when Bell Labs or whoever tried to create an optical-based pc, it was principally changing the silicon-based pc one to 1, precisely. All of the logic circuits and every little thing would run on optics. That’s onerous, and it continues to be onerous. I don’t suppose we will get there. Silicon photonics gained’t handle the difficulty both.
The fascinating piece is, once more, AI. For AI you don’t want very fancy computations. AI computation, the core of it’s comparatively easy. All the pieces is a factor referred to as matrix-vector multiplication. Info is available in, there’s a outcome, and it comes out. That’s all you do. However you must do it a billion instances. That’s why it will get difficult and requires numerous vitality and so forth. Now, the great thing about photonics is that it may possibly do that matrix-vector multiplication by its nature.
VentureBeat: Does it contain numerous mirrors and redirection?
NTT Analysis has an enormous workplace in Sunnyvale, California.
Gomi: Yeah, mirroring after which interference and all that stuff. To make it occur extra effectively and every little thing–in my researchers’ opinion, silicon photonics might be able to do it, however it’s onerous. It’s a must to contain totally different supplies. That’s one thing we’re engaged on. I don’t know in the event you’ve heard of this, however it’s lithium niobate. We use lithium niobate as a substitute of silicon. There’s a know-how to make it into a skinny movie. You are able to do these computations and multiplications on the chip. It doesn’t require any digital parts. It’s just about all finished by analog. It’s tremendous quick, tremendous energy-efficient. To some extent it mimics what’s occurring contained in the human mind.
These {hardware} researchers, their purpose–a human mind works with possibly round 20 watts. ChatGPT requires 30 or 40 megawatts. We will use photonics know-how to have the ability to drastically upend the present AI infrastructure, if we will get all the best way there to an optical pc.
VentureBeat: How are you doing with the digital twin of the human coronary heart?
Gomi: We’ve made fairly good progress during the last yr. We created a system referred to as the autonomous closed-loop intervention system, ACIS. Assume you could have a affected person with coronary heart failure. With this technique utilized–it’s like autonomous driving. Theoretically, with out human intervention, you may prescribe the fitting medication and therapy to this coronary heart and produce it again to a standard state. It sounds a bit fanciful, however there’s a bio-digital twin behind it. The bio-digital twin can exactly predict the state of the center and what an injection of a given drug may do to it. It may well shortly predict trigger and impact, determine on a therapy, and transfer ahead. Simulation-wise, the system works. We now have some good proof that it’s going to work.
Jibo can take a look at your face and detect your important indicators.
VentureBeat: Jibo, the robotic within the well being sales space, how shut is that to being correct? I feel it obtained my ldl cholesterol incorrect, however it obtained every little thing else proper. Ldl cholesterol appears to be a tough one. They had been saying that was a brand new a part of what they had been doing, whereas every little thing else was extra established. If you will get that to excessive accuracy, it might be transformative for a way typically individuals should see a health care provider.
Gomi: I don’t know an excessive amount of about that specific topic. The standard manner of testing that, after all, they’ve to attract blood and analyze it. I’m positive somebody is engaged on it. It’s a matter of what sort of sensor you may create. With non-invasive units we will already learn issues like glucose ranges. That’s fascinating know-how. If somebody did it for one thing like ldl cholesterol, we might carry it into Jibo and go from there.
