Google debuts more powerful “Ultra 1.0” AI model in rebranded “Gemini” chatbot

On Thursday, Google announced that its ChatGPT-like AI assistant, previously called Bard, is now called "Gemini," renamed to reflect the underlying AI language model Google launched in December. Additionally, Google has launched its most capable AI model, Ultra 1.0, for the first time as part of "Gemini Advanced," a $20/month subscription feature.

Untangling Google's naming scheme and how to access the new model is somewhat confusing. To tease out the nomenclature, think of an AI app like Google Bard as a car brand that can swap out different engines under the hood. It's an AI assistant—an application of an AI model with a convenient interface—that can use different AI "engines" to work.

When Bard launched in March 2023, it used a large language model called LaMDA as its engine. In May 2023, Google upgraded Bard to utilize its PaLM 2 language model. In December, Google upgraded Bard yet again to use its Gemini Pro AI model. It's important to note that when Google first announced Gemini (the AI model), the company said it would ship in three sizes that roughly reflected its processing capability: Nano, Pro, and Ultra (with larger being "better"). Until now, Pro was the most capable version of the Gemini model publicly available.

What happens when you trigger a car’s automated emergency stopping?

Most car crashes begin and end in a few seconds. That's plenty of time to get in a tiny micro-nap while driving. The famous asleep-at-the-wheel film scene in National Lampoon's Vacation, where Clark Griswold goes off to slumberland for 72 seconds while piloting the Wagon Queen Family Truckster (a paragon of automotive virtue but lacking any advanced driver safety systems), might be a comical look at this prospect. But if Clark were in the real world, he and his family would likely have been injured or killed—or they could have caused similar un-funny consequences for other motorists or pedestrians.

There's plenty of real-world news on the topic right now. Early in 2023, the Automobile Association of America's Foundation for Traffic Safety published a study estimating that 16–21 percent of all fatal vehicle crashes reported to police involve drowsy driving.

With the road fatality numbers in the US hovering close to 38,000 over the past few years, that means between 6,080 and 7,980 road deaths are linked to drowsy drivers. Further research by the AAA's Foundation finds that drivers likely under-report drowsiness in all car crashes. Nodding off while driving is as dangerous as—and potentially more dangerous than—driving drunk. And while drunk-driving figures have decreased between 1991 and 2021, the opposite is true for drowsy driving.
