How Much Energy Do Your AI Prompts Consume? Google Just Shared Its Gemini Numbers

Current measurements of AI’s impact aren’t telling the full story. Google has offered a new method it hopes to standardize.

The explosion of AI tools worldwide is increasing exponentially, but the companies that make these tools often don’t express their environmental impact in detail.

Google has just released a technical paper detailing measurements for energy, emissions and water use of its Gemini AI prompts. The impact of a single prompt is, it says, minuscule. According to its methodology for measuring AI’s impact, a single prompt’s energy consumption is about the equivalent of watching TV for less than 9 seconds.

That’s quite in a single serving, except when you consider the variety of chatbots being used, with billions of prompts easily sent every day.

On the more positive side of progress, the technology behind these prompts has become more efficient. Over the past 12 months, the energy of a single Gemini text prompt has been reduced by 33x, and the total carbon footprint has been reduced by 44x, Google says. According to the tech giant, that’s not unsubstantial, and it’s a momentum that will need to be maintained going forward.

Google did not immediately respond to CNET’s request for further comment.

Google’s calculation method considers much more

The typical calculation for the energy cost of an AI prompt ends at the active machine it’s been run on, which shows a much smaller per-prompt footprint. But Google’s method for measuring the impact of a prompt purportedly spans a much wider range of factors that paint a clearer picture, including full-system dynamic power, idle machines, data center overhead, water consumption and more.

For comparison, it’s estimated that only using the active TPU and GPU consumption, a single Gemini prompt uses 0.10 watt-hours of energy, 0.12 milliliters of water and emits 0.02 grams of carbon dioxide equivalent. This is a promising number, but Google’s wider methodology tells a different story. With more considerations in place, a Gemini text prompt uses 0.24Wh of energy, 0.26mL of water and emits 0.03 gCO2e — around double across the board.

Will new efficiencies keep up with AI use?

Through a multilayered series of efficiencies, Google is continually working on ways to make AI’s impact less burdensome, from more efficient model architectures and data centers to custom hardware.

With smarter models, use cases and tools emerging daily, those efficiencies will be critical as we immerse ourselves deeper in this AI reality.

For more, you should stop using ChatGPT for these things.

Keep Your Phone From Overheating When the Temperature Spikes

Hot weather can damage your iPhone or Android phone, sometimes permanently. Learn how to keep it safe.

As the East Coast of the US faces high winds and flooding from Hurricane Erin, the West Coast is about to be hit with a brutal heat wave. Along with increased danger from wildfires, the hot temperatures also create risks for your personal tech, specifically your smartphone.

Phones are more sensitive to extreme temperatures than most people realize. While the Pixel 6A made news earlier this year because of exploding, even the latest iPhone and Android models can overheat quickly if left in the sun or used heavily during hot weather.

When your phone gets too hot, it can slow down, shut off or even suffer long-term damage. High temperatures put stress on the battery and internal components, which can lead to reduced performance and a shorter lifespan. Whether you’re out on a hike, watching videos by the pool, or just leaving your phone on the dashboard, here’s what you need to know about overheating — and how to keep your device safe this summer.

Why is your phone overheating in the first place?

High temperatures — over 95 degrees Fahrenheit, according to Apple — can cause your phone to take precautions to protect its components. Your phone might overheat for many reasons, but here are some of the most common culprits:

Leaving your phone in direct sunlight
Keeping your phone in a hot environment, like a car on a hot day
Using your phone’s navigation system or other system-intensive tasks in hot conditions
Overusing your phone when it’s charging
A faulty battery or charger
Bugs in the software
Rogue apps or malware

Your phone might overheat from other causes, like a malfunctioning application or even a suffocating phone case, but the reasons above are the most likely causes of your phone getting too hot.

What does overheating do to your phone?

If the interior temperature of your phone exceeds its normal operating range and the device overheats, you can expect issues:

You may not be able to use your phone
Operations on your phone may slow down
Charging may slow or completely stop
Your signal may be weakened
Your camera’s flash may be disabled

There are also possible permanent harmful effects: Overheating can cause lasting damage to the battery, SIM card and other crucial parts inside your phone.

So how can you prevent your phone from overheating?

The most important thing is to keep your phone out of direct sunlight when possible, especially when it’s warm. Your phone might be fine in the grass on an overcast day, but the warmer the temperature, the less your phone can withstand the sun. At the beach, your phone can overheat in just a few minutes in the sun. The same is true if you put it in a sunny spot on the dash or seat of your car.

Instead, get your phone out of the direct light, whether it’s in your pocket, inside a backpack or under a towel/blanket or dashboard. Anyplace that will keep it away from sunlight will work.

It’s fairly easy to protect your phone from the sun, but high temperatures alone can also cause your phone to overheat. After only an hour, the inside of a car can reach 143 degrees Fahrenheit when it’s 100 degrees outside, for example, so a phone left in your cup holder could quickly overheat and get damaged. The short answer: Don’t keep your phone in a hot environment for an extended period of time, even if it’s not in direct sunlight. That includes your car, a sauna, the kitchen, the middle of the desert or anywhere near a fire.

Your phone’s optimal internal temperature should be somewhere between 32 degrees and 95 degrees Fahrenheit (0 degrees and 35 degrees Celsius). To prevent overheating, Apple recommends keeping the device in a place where the temperature is between negative 4 degrees and 113 degrees Fahrenheit (negative 20 degrees and 45 degrees Celsius).

While it might be tempting, don’t stick your phone in the freezer to cool it down. The Apple community boards have lots of warnings about the damage you can do to your phone by putting it in an icebox.

You should also follow these tips to prevent your phone from overheating

Don’t use graphics- or processor-intensive apps when your phone is charging. That includes massive mobile video games like PUBG Mobile or streaming apps like Netflix and Hulu.
Update your phone system software and apps to the latest software available. A bug in the software can cause overheating issues, so always stay up-to-date with your software.
Steer clear of third-party chargers. You’ll be fine almost always, but a cheaply designed charger could cause your phone to overheat.

Vivo Launches Mixed-Reality Headset, an Apple Vision Pro Competitor

Vivo Vision has many of the same design elements as Apple’s VR/AR, but is only available in China, for now.

Look-alikes of Apple products often pop up in China, and mixed-reality headsets have now joined the party. Chinese smartphone maker Vivo has introduced the Vivo Vision, a headset mixing both AR and VR, and it bears many similarities to the Apple Vision Pro.

The company announced the Vivo Vision Discovery Edition at its 30th anniversary celebration in Dongguan, China, saying it’s «the first MR product developed by a smartphone manufacturer in China, positioning Vivo as the first Chinese company to operate within both the smartphone and MR product sectors.»

The Vivo Vision, currently only an in-store experience in mainland China, has a curved glass visor, an aluminum external battery pack and downward-pointing cameras like the Vision Pro. But it also has some differences — an 180-degree panoramic field of view and a much lighter weight at 398 grams (versus the Vision Pro’s 650 grams).

CNET asked Vivo if it plans to sell the Vivo Vision to non-China markets, but the company did not immediately respond.

The Vivo Vision runs on OriginOS Vision, Vivo’s mixed-reality operating system. It supports 3D video recording, spatial photos and audio, and a 120-foot cinematic screen experience.

The starting cost in China will be $1,395 (converted to US dollars), compared to the Vision Pro at $3,500.

Even if the Vivo Vision came to the consumer market in the US, it might not matter much to Apple’s bottom line. The Vision Pro hasn’t been a big seller, likely because of the price tag. Still, the headset market is expected to grow quickly over the next several years, and Apple is already working on new versions of the Vision Pro, including one that’s more affordable than the original.

Jon Rettinger, a tech influencer with more than 1.65 million YouTube subscribers, says he’s not overly enthusiastic about VR/AR just yet. «It’s heavy, invasive and without a must-have use case,» Rettinger told CNET. «If the technology can go from goggles to glasses, I think we’ll see a significant rise. But if the current form factors stay, it will always be niche.

The YouTuber loves that the technology exists, but still doesn’t use it. «The honeymoon wore off. Aside from some gaming and content viewing, it’s still cumbersome, and I tend to go back to my laptop,» he said.
