Thanking your AI chatbot when it provides a response to a query may not require much energy on its own, but the cost of your interactions will add up over time—and a new tool from Hugging Face can tell you approximately how much.

The ChatUI energy interface estimates the energy consumption involved in messaging with an AI model in real time, with comparisons to common appliances like LED light bulbs and phone chargers. You can type in any query or utilize one of the suggested inputs to generate a response along with the corresponding energy requirement.

For example, a “professional email” took an AI just over 25 seconds to create and required 0.5 watt-hours, the equivalent of 2.67% of a phone charge. A 90-second script for testing transcription software required 1.4 watt-hours—7.37% of a phone charge, 22 minutes of an LED bulb, or 0.6 seconds of microwave use. (Responding to my “thank you” equaled 0.2% of a phone charge.)

Note that ChatUI is approximating, not providing exact measurements. The tool can run on various models, including Meta’s Llama 3.3 70B and Google’s Gemma 3.

How AI energy use compares to a Google search

According to estimates from the International Energy Agency (IEA), a single ChatGPT request requires nearly 10 times the electricity of a typical Google search at 2.9 watt-hours vs. 0.2 watt-hours, respectively. If ChatGPT was utilized in all 9 billion daily searches, that would require nearly 10 terawatt-hours of additional electricity per year, the equivalent usage of 1.5 million European Union residents.

AI’s environmental impact comes in large part from the power and water demands of running data centers. The IEA expects global AI electricity consumption to be ten times in 2026 what it was in 2023, and the water requirements by 2027 could be more than the entire annual usage of all of Denmark.

Huawei is gearing up to test its newest and most powerful AI processor, which the company hopes could replace some higher-end products of U.S. chip giant Nvidia. From a WSJ report: Huawei has approached some Chinese tech companies about testing the technical feasibility of the new chip, called the Ascend 910D, people familiar with the matter said. The company is slated to receive the first batch of samples of the processor as soon as late May, some of the people said.

The development is still at an early stage, and a series of tests will be needed to assess the chip’s performance and get it ready for customers, the people said. Huawei hopes that the latest iteration of its Ascend AI processors will be more powerful than Nvidia’s H100, a popular chip used for AI training that was released in 2022, said one of the people. Previous versions are called 910B and 910C.

The consequences of President Trump’s tariff policies are starting to kick in. Crowdfunding platform Kickstarter just announced something called a “Tariff Manager Tool” that lets creators add new surcharges to funded projects. This should help these creators deal with the unexpected costs of Trump’s global trade war.

Here’s how it works. Creators will be able to apply per-item surcharges to account for tariff-related cost increases. These charges will appear as a separate line item on the payment page for folks who have funded the project. It only applies to items heading to US-based shipping addresses. 

Not everyone will want to, or be able to, pay an additional fee for something they backed months or years ago when the economy was stronger. Backers will be given the option to decline the surcharge, in which case a creator can issue a refund. A blog post does suggest that backers and creators could find “another resolution,” beyond a refund, but didn’t get into specifics.

“We understand that asking backers to pay an additional fee—especially after a campaign has ended—can be sensitive,” Kickstarter said. “Our goal is to provide you with the flexibility and transparency necessary to navigate those conversations with clarity and care.”

Many Kickstarter projects rely on parts manufactured in China, Vietnam and other places that are now subject to exorbitant tariffs. This is poised to be exceptionally brutal for American small businesses, but Kickstarter creators face another hurdle. Backers typically fund a project months or years before fulfillment. It’s going to be unpleasant to find a new surcharge for something funded back in 2023 or whenever.

A tabletop game maker called Stonemaier Games is suing President Trump over these tariffs. The small Missouri-based company has joined an upcoming lawsuit that alleges the president’s actions have put the livelihood of its employees in jeopardy. The suit challenges the constitutionality of the tariffs and noted that they will cost the company $1.5 million in additional import fees. Stonemaier is primarily known for the excellent Wingspan, which made our list of the best board games.

Retailers across the country, both large and small, have been warning consumers that prices are about to shoot up in May and that many products could become totally unavailable. This is due to both the tariffs and a recent executive order by Trump that eliminated a loophole that allowed small packages to avoid additional import charges. If you’ve been eyeing a particular gadget, you should probably get on that sooner rather than later.

The Samsung Galaxy Watch 7 is back on sale, this time for the lowest price we’ve seen since Black Friday. This particular deal is for the 40mm model and only for the green colorway, but you can always swap out the strap if that’s not quite your style. This variant is 30 percent or $90 off the usual price of $300. In other words, it can be yours for $210. 

Perhaps a cream strap is more of a match for your look. In that case, you can save on a version of the Galaxy Watch 7 with that too as it has dropped to $240. For the same price, you can get a 44mm Galaxy Watch 7 in green (which has a slightly larger, 1.5-inch screen). That also marks a discount of $90.

Samsung hasn’t rocked the boat much with the last few iterations of the Galaxy Watch, but it’s largely a case of “if it ain’t broke, don’t fix it” — even if we do have some reservations about the latest generation of the wearable. We gave the Galaxy Watch 7 a score of 85 in our review. The always-on display’s impact on battery life is our main bugbear, while running a finger along the bezel for navigation feels clunky.

That said, the Galaxy Watch 7 offers reliable activity tracking (with automatic logging for walks) and it delivers speedy performance. We appreciate that it looks more like a traditional watch than much of the competition too. While the Google Pixel Watch 3 is our pick for the best smartwatch for Android users, there’s still a lot to like about the Galaxy Watch 7 — especially at this price.

Researchers claiming affiliation with the University of Zurich secretly deployed AI-powered bots in a popular Reddit forum to test whether AI could change users’ minds on contentious topics. The unauthorized experiment, which targeted the r/changemyview subreddit, involved bots making over 1,700 comments across several months while adopting fabricated identities including a sexual assault survivor, a Black man opposing Black Lives Matter, and a domestic violence shelter worker.

The researchers “personalized” comments by analyzing users’ posting histories to infer demographic information. The researchers, who remain anonymous despite inquiries, claimed their bots were “consistently well-received,” garnering over 20,000 upvotes and 137 “deltas” — awards indicating successful opinion changes. Hundreds of bot comments were deleted following the disclosure.

LG’s 2025 lineup of its QNED Evo premium LCD TVs will be available to buy starting in May, following an initial reveal at the end of 2024 ahead of CES. The flagship QNED9M is the first QNED (Quantum Nano-Emitting Diode) TV capable of leveraging LG’s True Wireless tech to wirelessly transmit and display 4K content, a feature previously exclusive to the company’s more premium OLED TVs.

LG might be best known for its OLEDs these days, but the trickling down of the wireless functionality it first introduced back in 2023 with the Zero Connect Box is proof that the company isn’t forgetting about its more affordable LCD sets. LG claims that with devices like game consoles or set-top boxes plugged into that external box, you can expect to transmit 4K content at up to 144Hz with no latency or loss in picture and audio quality. In a win for clutter-haters (and who isn’t one of those), the only cable you’ll need to plug into the TV itself is its power cord. It’s worth noting that models 55-inch and below top out at a refresh rate of 120Hz.

The QNED Evo lineup is powered by LG’s Alpha AI processor. The updated TVs also benefit from LG’s Dynamic QNED Color solution, replacing quantum dot tech, which produces more vivid and lifelike colors. QNED TVs combine quantum dot and nanocell technology with Mini LED backlighting that employs thousands of dimming zones. As a result, you get brighter images and higher contrast compared to a more traditional LCD panel, even if it’s still a step down from the self-lit pixels on an OLED display.

The new AI Magic Remote you get in the box has a dedicated AI button, which when pressed allows you to make personalized voice requests. The baked-in AI tech can also tweak the TV according to your personal audio and visual preferences, enhance faces and key scene elements, and produce virtual 9.1.2 surround sound from the built-in speakers.

The TVs also double as smart home hubs, offering multi-platform connectivity through LG ThinQ and Google Home. AirPlay and Google Cast are from your iPhone or Android device of choice.

With sizes ranging from 50 to 100 inches, the refreshed QNED Evo models roll out next month in the US, but prices still haven’t been announced.
