I saw Nvidia's RTX-powered AI avatar in action, and this digital human interface has a sense of humor
Nvidia is making that fabricated, human-like AI we see in movies more of a reality, and that didn't really hit me until I saw its Project R2X, an AI avatar that essentially lives on your PC, in action at Computex 2025.
We've seen how AI is advancing in different spaces, from ChatGPT being an amazing education tool to Google Veo 3 and Flow being the future of AI filmmaking. But, instead of just typing in prompts, what about a realistic-looking digital human interface you can actually interact with right on your PC? As in, one that will look and talk to you like, well, a person.
That's Nvidia's Project R2X in a nutshell. Sure, it's not like there isn't AI avatars around that can easily be generated, but one that can act as your personal assistant through your PC is different.
Honestly, it was jarring to see Aki, the Nvidia AI avatar I saw during the demo, casually standing right on the PC's display with a Nvidia hoodie on, staring right at me — waiting for its next instructions. But I didn't realize it came with a sense of humor.
Remember when Matthew McConaughey told monolithic robot TARS to drop its humor to 75% in Christopher Nolan's "Interstellar?" and it still had a few jokes? Well, I was getting those same vibes. Just by speaking to Nvidia's avatar and giving it directions, its voice, personality and appearance can completely change to your liking.
Will Nvidia's Project R2X be a major help to developers and tech enthusiasts in need of getting tasks done through agentic AI? Without a doubt, but putting a conversational, human-like spin on this AI gives it some spark — and here's how it went.
Nvidia's Project R2X is a digital human interface that helps developers and enthusiasts with PC tasks autonomously. In other words, it's like a personal AI avatar on your desktop that can be used to can scan complex files, carry out workflows, optimize PC settings, mod games and answer questions just by speaking to it — all through RTX-powered systems.
By using RTX Neural Faces to generate a 3D avatar, Audio2Face to make sync lip and tongue movement when speaking and Nvidia ACE 2.4 to apply facial blur animations, Nvidia's AI assistant gains a lifelike appeal. As for how it gets all of its information, it can be used with AI models like OpenAI's GPT-4o, xAI's Grok or, if you're familiar with Python, code and customize to your liking (dealer's choice). There's also Nvidia's NIM (Nvidia Inference Microservices) and AI Blueprints that give it more artificial brain power, like turning a PDF into a full-blown podcast.
If you give it eyes (i.e., a webcam), it can even see you and your surroundings. Not unlike other recent visual AI like Copilot Vision, it can tell you exactly what an object is in reality. Plus, similar to Microsoft Recall, it can see what's on display and guide you through activities, like how to edit an image, generate a video or use various apps.
So, not completely unlike what we've seen with Google Gemini or ChatGPT, especially as they continue to evolve. However, Nvidia's Project R2X puts a face on it all, and it gives you the choice of quick customization to your liking.
The AI avatar prototype was revealed at CES 2025, but it's now getting closer to being released (I was told it would be available this summer).
As it was brought up in the demo, from the way it slightly tilts its head when being asked a question to its subtle movements and blinks as it idly waits for instructions, Nvidia's Project R2X can feel a tad uncanny at first. And that's purely because this AI avatar is something to see and speak to.
"As soon as you see a face, it naturally invokes a humanoid input, so you actually want to start talking to it like a person," the Nvidia representative stated. That rings true, as I was automatically aware of its presence, like somebody else being in the room.
At least it knows how to break the ice. During the demo, a Nvidia representative asked Aki to change its voice from its upbeat, helpful tone to something extremely robotic. The AI avatar replied with a very sarcastic "I can't actually change my voice. If there's anything else you'd like to know or need help with, let me know" in the robot voice that was asked.
As soon as you see a face, it naturally invokes a humanoid input, so you actually want to start talking to it like a person
Then, when told to change to a somber, medical advisor type tone, Aki said the same thing but changed voice as it was saying it. Was this deliberate or AI irony? I'm not sure, but with its detailed facial expressions, it certainly looked like Project R2X had a sense of humor.
Now, AI can crack some jokes, as we've seen ChatGPT drop some fiery roasts when asked, but putting a realistic face to it makes it feel far more engaging (and brutal, if it ends up roasting me).
As the representative touched on, it's easy to change the tone, appeal and personality of its AI agent just by asking it, or by making the AI assistant from scratch.
"We'll be releasing this as a blueprint reference, and we'll release the source, as well as the application as an .exe," the Nvidia rep said. "So people can open up their own Unreal scene and put in whatever 3D asset they want. If you want it to be your own character, you write your own prompt for personality and you get your own personalized assistant."
Nvidia's Project R2X can assist with a wealth of tasks just by asking it, and by applying the apps you want it to work with in its interface, it can also connect to Project G-Assist (another helpful AI tool from Team Green).
From being able to open up in-game overlay analytics to connecting other apps like Discord or Spotify to start a stream or play some tunes, all it takes is asking your own AI avatar and it will be done in only moments. It aims to streamline workflows (or gaming flows?) to make navigating around your PC even easier (that's right, just like an assistant), and for developers, content creators or streamers, that's a helpful feature to have.
It's one thing to get answers from a chatbot, but it's another to have a human-like AI agent giving you a step-by-step guide on how to tackle tasks, apply mods in games and work in the background autonomously. Nvidia Project R2X impresses, but its ability to change personality and add a touch of humor to your daily PC activities makes it feel more, well, genuine.
If a 3D-generated AI model constantly looking at you from your screen is a tad too eerie, by the way, the avatar can be minimized, resized and put anywhere on screen. Nvidia joked it would even want an animation of it moving around the screen as you dragged it (which wouldn't be a bad idea).
Nvidia Project R2X is set to be available to all sometime this summer, and it will be interesting to see how RTX 50-series GPU holders will make use of the digital human interface. More importantly, however, how they will customize their AI avatar to be a nice, friendly assistant or a wise-cracking, sarcastic jokester that will give your ego a battering with roasts.

Why Navitas Semiconductor Rocketed 164% in May
Navitas is a small-cap semiconductor stock with declining revenues and operating losses. However, the company was named as a partner for Nvidia's upcoming Kyber data center power infrastructure. Navitas took the opportunity of a higher stock price to raise cash via equity sales, bolstering its balance sheet. 10 stocks we like better than Navitas Semiconductor › Shares of Navitas Semiconductor (NASDAQ: NVTS) rocketed 164.2% in May, according to data from S&P Global Market Intelligence. Entering the month, Navitas has been a small designer of gallium nitride (GaN) and silicon carbide (SiC) chip designs. These niche chips had primarily targeted electric vehicles and electrified infrastructure. But given the recent downturns in these markets, Navitas had seen its revenue go into reverse and its bottom line continuing to lose money. But in mid-May, Nvidia named Navitas as a key partner for Nvidia's upcoming Kyber data center infrastructure, which will be a new architecture to support Rubin-based sever racks beginning in 2027. While other power chip providers were also named, the fact that Navitas was so small, at just $350 million or so market cap at the time of the announcement, caused a massive rally in the stock. Navitas then used the opportunity to sell stock and bolster its balance sheet, extending its runway, likely until the 2027 time frame. As Nvidia explained in a May 20 blog post, the current 54 V DC power distribution systems in today's data centers will push up against their physical limits as AI server racks go to needing 200 kilowatts to power next-generation AI chips. To counter this, Nvidia is developing a ground-up redesign of data centers to an 800 V HVDC power architecture. Nvidia also noted that it was collaborating with a number of power chip and infrastructure companies early on as it develops the new data center power infrastructure, which Nvidia plans to unveil in 2027 for its upcoming Rubin-based systems. The following day, Navitas published its own blog post explaining how the new 800 V architecture will use both Navitas' SiC chips in the power room of data centers, which convert AC grid power to DC power for the data center, and then GaN-based power converters at the server rack level. The day of the blogs, May 21, Navitas rocketed 150% higher, before retreating. But then the following week, Navitas disclosed it had exhausted its $50 million equity at-the-market sales facility, and that it had filed for a new $50 million facility. Normally, when a company notes it has and will dilute shareholders, the stock goes down. But since Navitas' stock had gone up so much, investors viewed the capital raise as a positive, in that it fortified Navitas' balance sheet to bridge more of the time gap between now and 2027. While the prospect of a small company partnering up with Nvidia is highly tantalizing, there weren't any financial terms disclosed in the announcements. That makes sense, as the platform isn't even fully developed yet, and revenues from the venture aren't likely to come before 2027. So it's hard to say right now if Navitas has moved too far, too fast. Still, last month's cash raise will bolster Navitas' balance sheet, giving it more time to build out its platform in anticipation of the 2027 Kyber rollout.

OpenAI finds more Chinese bad actors using ChatGPT for malicious purposes
Chinese bad actors are using ChatGPT for malicious purposes – generating social media posts to sow political division across the US and seeking information on military technology, OpenAI said. An organized China-linked operation, in one such incident dubbed 'Uncle Spam,' used ChatGPT to generate social media posts that were supportive and critical of contentious topics related to US politics – and then posted both versions of the comments from separate accounts, the company said in a report released Thursday. 'This appears likely designed to exploit existing political divisions rather than to promote a specific ideological stance,' OpenAI wrote in the report, describing what is known as an influence operation. Advertisement 3 A growing number of Chinese bad actors are using ChatGPT for malicious purposes, OpenAI said. REUTERS OpenAI said it followed Meta's lead to disrupt this operation, after the social media conglomerate discovered the actors were posting at hours through the day consistent with a work day in China. The actors also used ChatGPT to make logos for their social media accounts that supported fake organizations – mainly creating personas of US veterans critical of President Trump, like a so-called 'Veterans For Justice' group. These users also tried to request code from ChatGPT that they could use to extract personal data from social media platforms like X and Bluesky, OpenAI said. Advertisement While the number of these operations has jumped, they had relatively little impact as these social media accounts typically had small followings, OpenAI said. Another group of likely Chinese actors used ChatGPT to create polarizing comments on topics like USAID funding cuts and tariffs, which were then posted across social media sites. In the comments of a TikTok video about USAID funding cuts, one of these accounts wrote: 'Our goodwill was exploited. So disappointing.' Advertisement 3 Another group of likely Chinese actors used ChatGPT to create polarizing comments on topics like USAID funding cuts and tariffs. REUTERS Another post on X took the opposite stance: '$7.9M allocated to teach Sri Lankan journalists to avoid binary-gender language. Is this the best use of development funds?' These actors made posts on X appearing to justify USAID cuts as a means of offsetting the tariffs. 'Tariffs make imported goods outrageously expensive, yet the government splurges on overseas aid. Who's supposed to keep eating?' one post said. Advertisement Another read: 'Tariffs are choking us, yet the government is spending money to 'fund' foreign politics.' 3 The operations used ChatGPT to write divisive comments on some of the Trump administration's policies, including USAID funding cuts and tariffs. AFP via Getty Images In another China-linked operation, users posed as professionals based in Europe or Turkey working for nonexistent European news outlets. They engaged with journalists and analysts on social media platforms like X, and offered money in exchange for information on the US economy and classified documents, all while using ChatGPT to translate their requests. OpenAI said it also banned ChatGPT accounts associated with several bad actors who have been publicly linked to the People's Republic of China. These accounts asked ChatGPT for help with software development and for research into US military networks and government technology. OpenAI regularly releases reports on malicious activity across its platform, including reports on fake content for websites and social media platforms and attempts to create damaging malware.
