Artificial intelligence has already begun to change the way we conduct research, and now OpenAI has just released the latest update to ChatGPT, which it says will open up “deep research” to almost everyone.
The new deep research tool is rolling out to ChatGPT Pro subscribers today, just days after the launch of the 03-mini reasoning model.
“Today, we’re launching Deep Research in ChatGPT, a new agent capability that can conduct multi-step research on complex tasks on the internet,” a blog post reads, promising that the model can “do in just tens of minutes what would take a human hours to do.OpenAI ChatGPT’s powerful “deep research” upgrade gets open source copies in just 24 hours
I just tested ChatGPT’s new o3-mini model, rating its problem-solving and reasoning abilities with 7 prompts — and the results blew my mind
This new agent “can work independently for you,” “finding, analyzing, and synthesizing hundreds of online sources to create research analyst-level synthesis reports” based on a series of prompts.
It’s powered by the upcoming ChatGPT o3 model and is aimed at finance, science, policy, and engineering research, but OpenAI also says it can also be used to make purchasing decisions and help with detailed product research (which could be another warning for Google).
Using the new tool is simple, too. Users simply select “Drill down” in the ChatGPT message editor and enter a query, with the option to attach additional context via files and spreadsheets.
Doing so will see the cited articles in the sidebar, where you can also track your progress. OpenAI says it can take anywhere from five minutes to half an hour to complete a deep dive task.

Sennheiser’s HD 505 headphones offer audiophile-grade open-back audio
Sennheiser has just unveiled the latest entry-level headphone in its more “analytical” headphone series, the HD 505. The 500 series has always been Sennheiser’s more affordable line, and the HD 505 is second only to the Sennheiser HD 600 in that line.
Sennheiser points out that the HD 505 can achieve best-in-class audio levels without causing fatigue. It is the name of the Sennheiser 500 series, providing ultimate comfort and

dynamic listening experience for hours on end.
Sennheiser has updated the clamping function in the new headphones and redesigned the outer cover to be more cushioned, giving you an unparalleled listening experience when listening to music. Weighing only 237 grams, the Sennheiser 505 headphones are very light and suitable for long-term wear.
However, the overall sound of the HD 600 is more natural, which is particularly noticeable in the mid-range. It feels like there’s more room for these elements to move in these frequencies – when they’re not sandwiched between the HD 505’s steeper bass and highs, there’s more room to play
Sennheiser says the new headphones feature improved transducers designed to provide better bass and treble extension than previous 500-series products while maintaining transparency in the music.

Logitech G Pro X Superlight 2 launched with hybrid switch, 95 hours of battery life
The first-generation Logitech G Pro Wireless was a major breakthrough for wireless gaming mice. It was the first mouse to offer latency comparable to that of a wired mouse, making it a popular choice among professional esports players. The 2020 Logitech G Pro X Superlight Wireless goes a step further, being even lighter and more portable than the first generation while still maintaining the same great performance. Logitech has now launched a new mouse in the Superlight series, the Logitech G Pro X Superlight 2. Let’s discuss it here.Also extendedLogitech G Pro X Superlight 2 Mouse Battery

MSI Prestige 16 AI Evo (2025) review
This easy-to-carry 16-inch Windows ultraportable has everything you need The MSI Prestige 16 AI Evo is a powerful 16-inch ultraportable that’s well-designed, easy to carry, and sports a 10-inch display.
MSI Prestige 16 AI Evo (2025) Laptop Battery
All-day battery life lets you work anywhere without having to carry a charger. However, the screen is too bright, which is annoying, and the “AI” features are mediocre at best. The MSI Prestige 16 AI EVO ($1,399) is one of the first major AI laptops of 2025, and after a week of use, I think it’s a decent first for the new Intel Arrow Lake chips.
Our MSI Prestige 16 AI EVO review unit is the first laptop I’ve tested with an Intel Core 9 285H CPU, the new kid on the block in Intel’s Arrow Lake family. This is the most powerful chip Intel unveiled at CES 2025, and it performs well on the Prestige 16 AI Evo.
After using it for work and play, I can confirm that it is more than enough for your daily work in the office, and the MSI Prestige 16 AI Evo (2025) Laptop Batteryis longer than I expected. It can even run games in a pinch.
My first impression of the MSI Prestige 16 AI EVO is that it is very easy to carry around. It weighs just over 3 pounds, which is not light, but the magnesium-aluminum alloy chassis actually feels lighter than its size.
I say this because our MSI Prestige 16 AI EVO review unit lasted for more than 15 hours in our MSI Prestige 16 AI Evo (2025) battery test, which requires the laptop to surf the Internet over Wi-Fi non-stop (with the screen brightness turned down) until theMSI Prestige 16 AI Evo (2025) Laptop Battery
is exhausted. We then averaged the laptop’s multiple runs to get a final score, and this MSI laptop performed far better than competing laptops like the HP Omnibook Ultra.
While the MSI Prestige 16 AI Evo (2025) Laptop Batterylife doesn’t match the best laptops, including basically any laptop with an Apple chip or a Qualcomm Snapdragon chip, it comes pretty close while offering something that those two ARM-based chip families can’t match: x86 compatibility. So if you want to be able to use the full suite of Windows x86 apps while also wanting the MSI Prestige 16 AI Evo (2025) to last longer, there’s good news for you. For example, this laptop comes pre-installed with MSI Center S. This is MSI’s software that gives you convenient access to a variety of performance settings, including “AI Zone,” which lets you enable features like AI noise reduction while you’re on a call, and a Smart Guard feature that automatically turns the screen off when you leave and back on when you return. With a large screen, light weight, and a comfortable keyboard, this device is perfect for getting work done on the go. While I wish it had a less reflective OLED screen option, I can’t fault the display quality as our display tests showed it averaged over 400 nits of brightness and covered both the sRGB and DCI-P3 color gamuts.

Toshiba Encore 2 review: This Windows 8 tablet is great for the price
The Encore 2 is one of the first “cheap” Windows 8 tablets, and there’s no doubt we’ll start seeing more of them. In fact, several were unveiled at this year’s IFA event, including a $119 Encore 2 Mini with a 7-inch display.
Very cheap for its size, solid industrial design,
Toshiba Encore 2 Tablet Battery
Long Life
Encore 2 Specs
Inside, the Encore 2 is equipped with a 1.4 GHz quad-core Intel Atom Z3735F processor, 1 GB of RAM, 802.11n Wi-Fi, and a Micro USB 2.0 port for charging and connecting external devices. Onboard storage is 32 GB, and a 64 GB version is also available. That’s more than you’d expect from a device at this price point with 16 GB or less. It’s also easy to increase storage by adding a microSD, microSDHC, or microSDXC card (up to 128 GB).
Toshiba also throws in a free year of Office 365 Personal subscription (normally $69.99 per year), which includes 1 TB of One Drive storage. You can install Office 365 Personal on one tablet and one PC or Mac.
The screen is definitely not HD—it’s only 720p, in fact, but I guess it’s good enough. The front and rear cameras are adequate, but nothing special. The front camera is 1.2 megapixels, and the rear camera is 5 megapixels, which are pretty good for a tablet at this priceToshiba Encore 2 Tablet BatteryIt lasts up to 10 hours, but in my daily use (browsing the web, checking email, playing games, and watching YouTube videos), Toshiba Encore 2 Tablet Batterylasted closer to 8 hours. If you really want to get more battery life, turn down the screen brightness, as it’s set to the brightest setting from the factory. The tablet comes with Dolby Digital Plus, and two small speakers pointed toward the back of the tablet. It’s easy to cover them with your fingers, which I find annoying, but headphones are usually a better option for listening to audio on a tablet anyway. Another thing that might put some people off is that there’s no HDMI-out port to connect to a larger monitor.
Speakers pointed toward the back of the tablet Modern apps
The Encore 2 is designed primarily for Modern UI and apps, with the desktop if you really want. Since it’s running Windows 8.1, you can put two Modern apps side by side and use them simultaneously. However, Modern UI does slow down if you have too many apps running at once. I guess the Atom processor can only handle so much multitasking.
You’ll get your apps from the Windows Store, and since I find the best use for this tablet is media consumption, I’ll load it up with video and music apps and a few games.

Xiaomi Redmi Buds 5 Pro review: Cheap true wireless earbuds with all the features of the big brands?
AirPods Pro? No Redmi Buds 5 Pro. It’s hard not to think of Apple headphones when looking at these new Xiaomi headphones, both in terms of design and in terms of the full range of features they offer given their price.
It’s worth the money: LDAC lossless audio, immersive sound, active noise cancellation, multipoint, IP54 and even dual sensors. The execution still needs to be as good as this feature richness. Since Xiaomi did not include a wireless charging system in this case, the USB-C port will be the only way to charge it. The indicator light on the front shows the Xiaomi Redmi Buds 5 Pro Headphones Battery level and status of the Xiaomi Redmi Buds 5 Pro headphones.
The equalizer brings good sound quality. However, as soon as you press the play button, the smiley face appears again. The sound quality of the Buds 5 Pro is above average for 100 euro headphones. To do this, Xiaomi equipped them with a dual transducer: an 11 mm transducer dedicated to low frequencies and a 10 mm transducer dedicated to the highest frequencies. Finally, Xiaomi announces an impressive 10 hours of battery life for its Buds 5 Pro, thanks to the 54 mAh Xiaomi Redmi Buds 5 Pro Headphones Batteryin each earphone. Note, however, that this is measured without noise cancellation enabled, so these devices lose a strong argument. With ANC enabled, we found an excellent battery life of about 11 hours!
Its charging case is equipped with a 480 mAh Xiaomi Redmi Buds 5 Pro Headphones Batterythat is claimed to be able to fully charge it a little more than three times. Test results It would be an illusion to think that this Buds Pro 5, which costs a minimum of 100 euros, is able to offer quality and features comparable to models of almost 300 euros.
However, Xiaomi has shown some virtuosity in this regard, thanks to good autonomy, consistent sound quality (after equalization) and correct noise cancellation. We lament that the gimmick of lossless sound quality is difficult to really feel and that immersive audio cannot be achieved, but if you do not need these two things, this earphone is a good choice and a bargain.

What is DeepSeek? Big tech companies continue to build AI in big ways.
About two weeks ago, Wall Street panicked when Chinese startup DeepSeek released an AI system that was far more effective than its American rivals.Investors, who have poured trillions of dollars into tech stocks over the past few years, wondered whether the tens of billions of dollars tech companies have spent on new data centers suddenly looked overextended.
But the biggest tech companies made clear in recent earnings reports that they don’t think they’re overextended in building new data centers.
Amazon hinted Thursday that its capital spending, which includes data center construction and other projects like warehouses, could exceed $100 billion this year. Microsoft said its spending could exceed $80 billion. Alphabet said it would spend $75 billion, while Meta reiterated plans for $65 billion in capital expenditures.
Combined, they could spend about $100 billion more on these projects than they did last year.
Executives urged patience. The problem, they said, is that customer demand for artificial intelligence outstrips the company’s capabilities. The only way to meet demand is to develop as many products as quickly as possible.
“Every time I see someone else doing something better, I say, ‘Ah, we should do that,’ ” Meta CEO Mark Zuckerberg told employees at a companywide meeting last week, according to a recording obtained by The New York Times. Competition is good, but we need to make sure we can win.”
Here are some keys to understanding this consumer-driven moment in the tech industry:
Tech companies need more data centers than they have now.
Many companies say they are constrained by the availability of chips, land and electricity to build data centers, so they are racing to open more. Microsoft, Alphabet and Amazon have all said their cloud sales could be higher if there was enough capacity. Cloud services are the quintessential way to deliver artificial intelligence to customers.
Alphabet Chief Financial Officer Anat Ashkenazi told investors that Alphabet is seeing “demand that exceeds our available capacity.” “So we’re going to work on that and make sure we can provide more capacity.”
Microsoft has been saying it has been constrained for some time, and previously told investors that pressure would ease early this year. But last week, when the company reported its latest earnings, executives told investors it might take until the summer to have enough capacity to meet all the demand. Shares of the company fell about 5% in after-hours trading after the report was released.
Greater efficiency, they say, will expand the use of and demand for AI
While many people think of data centers as expensive, power-hungry places to develop advanced AI systems, they are also where AI is deployed. Those are two different steps: training the model that underpins ChatGPT, and asking ChatGPT for recipe suggestions.
The industry calls deploying AI “inference”; a growing number of tech companies say their businesses are booming in this area.
Microsoft CEO Satya Nadella told investors last week that as costs fall, “AI I will become more pervasive.”
Amazon CEO Andy Jassy told investors Thursday that while a world where every application includes AI may be hard to imagine, “it’s a world we’ve been thinking about.” At the heart of that vision, he said, is inference.
He believes that lowering the cost of inference will follow the pattern of previous technology trends: As systems become cheaper to deploy, customers will “get excited about other things they can build that they previously thought were too expensive, and they usually end up spending more money on.”
These companies say they have to think long-term.
Cloud providers are used to giving customers the illusion of endless supply, which means they have to juggle having enough data centers online to play the video you want or answer your chatbot query. But they also can’t build too much in advance, which would tie up billions of dollars that could be deployed elsewhere. Balancing the two — especially when securing data center land, chips and electricity can take years — is a big challenge for these companies.
Executives say they can adjust how their investments are used, between building and deploying AI models and between serving their own core businesses and customers. Nadella said Microsoft’s infrastructure is “very flexible.” Ashkenazy said Google is flexible, too. For example, it can “repurpose capacity” to serve Google Search instead of cloud customers.
Zuckerberg said Meta was working on DeepSeek and how it could improve efficiency, but that investing heavily in data centers would be a strategic advantage against smaller, more nimble rivals.
“We serve over a billion people — that’s a lot of people, so more and more machines are going to be used to run inference,” he told employees.
Whatever the reason, cutting into profits — even the huge profits of tech giants — is unlikely to excite investors.
Hands on with the Dreame U10 Cordless Vacuum Cleaner: Does it do the job well?
Dreame U10: What’s in the box? In terms of design, the Dreame U10 is sleek and lightweight, weighing 1.65 kg (excluding the extension rod), which is lighter than some laptops. However, prolonged use may cause fatigue. It comes with two extension rods, a pole (one meter long), and a wide combination tool. Since it has no wires attached, it can be very convenient to use for cleaning without worrying about tripping or getting tangled in wires.
DetachableDreame U10 Cordless Vacuum Cleaner Battery
The pack can be mounted on the U10 base and comes with 7 2,000mAh
At the heart of the Dreame U10 is a high-speed brushless motor that spins at 100,000 rpm and has a suction power of 100AW. It has three power modes that can be switched using the button on the back of the U10. I found the suction power to be powerful enough to pick up dust, dirt, and debris.
The main unit contains a 0.5-liter dust cup that can be easily removed for emptying and washing. Its battery is also removable and can be charged separately using the small charger provided.
The five-layer filtration system inside the dust cup consists of a filter element, sponge filter, multi-cone filter, metal mesh filter, and cyclone filter, as shown in the picture below. According to Dreame, the U10’s filtration system is up to 99.9% efficient and can capture even the tiniest dust particles.
This versatile brush is suitable for both carpets and hard floors. Its V-shaped bristles remove dirt, dust, and hair from all types of surfaces. An LED light is installed on the brush head to illuminate darker areas, allowing users to see dirt and dust they may have missed.Dreame U10 Cordless Vacuum Cleaner Battery. According to the company, it can provide 40 hours of runtime. Since almost no one will use the U10 for 40 minutes continuously, it can easily meet typical cleaning needs without frequent charging.
Dreame U10 Cordless Vacuum Cleaner Battery
It takes nearly 3.5 to 4 hours to fully charge the pack.On the lowest power setting, the Dreame U10 is quiet. However, when set to the highest level, the noise gets louder, although you can still hear people talking around you. In addition, the device is still manageable when cleaning on the highest setting.
Maintenance of the Dreame U10 is very simple, and only requires emptying the dust collected in the dust cup. Users can simply press the button on the dust cup and pull it out of the U10. After that, the dust cup and its filter system can be easily removed, and both can be washed under water.
Final ThoughtsAll in all, the Dreame U10 cordless vacuum cleaner is positioned as an efficient, powerful and user-friendly cleaning choice. With features like a high-speed motor, adaptive brush design, LED lights, and advanced filtration, the U10 can handle a variety of cleaning tasks with ease. If you’re considering switching from a traditional corded vacuum cleaner to the convenience of cordless cleaning, the U10 won’t let you down.

US reportedly investigating whether DeepSeek used restricted AI chips
The U.S. Commerce Department is investigating whether DeepSeek, a Chinese company whoseAI models have stunned the tech world with their performance, used chips banned from export by the U.S., according to people familiar with the matter.
China’s DeepSeek last week launched a free assistant that it said uses less data and costs a fraction of the U.S. model. Within days, it became the most downloaded app on Apple’s App Store and raised concerns about the U.S. lead in AI, sparking a sell-off that wiped out about $1 trillion in market value from U.S. tech stocks.
Current restrictions on Nvidia’s AI processors are aimed at blocking its most advanced chips from entering China.
Organized smuggling of AI chips into China has been traced to countries including Malaysia, Singapore and the United Arab Emirates, the sources said.
The U.S. Commerce Department and DeepSeek did not immediately respond to requests for comment.
An Nvidia spokesman said many of the company’s customers have business entities in Singapore and use them to make products for shipment to the U.S. and the West.
Nvidia said: “We insist that our partners comply with all applicable laws, and we will take appropriate action if we receive any information to the contrary.”
DeepSeek said it used Nvidia’s H800 chip, which can be legally purchased in 2023. Reuters could not determine whether DeepSeek used other regulated chips that are not allowed to be shipped to China.
DeepSeek also apparently has Nvidia’s lower-performance H20 chips, which can still be legally shipped to China. The United States has considered controlling these products during the Biden administration, and new Trump officials are also discussing it.
Dario Amodei, CEO of artificial intelligence company Anthropic, said earlier this week that “a significant portion of DeepSeek’s AI chip inventory appears to be chips that are not banned (but should be banned), chips that have been shipped before they were banned, and some chips that appear to be very likely smuggled.”
The United States has implemented a series of restrictions banning the export of AI chips to China and plans to restrict exports to many other countries.
