Tesla denied having fatal crash data until a hacker found it

Google’s still not giving us the full picture on AI energy use

“We’re not comfortable revealing that for various reasons,” Dean told me on our call. The total number is an abstract measure that changes over time, he says, adding that the company wants users to be thinking about the energy usage per prompt.

OpenAI does publicly share its total, sharing recently that it sees 2.5 billion queries to ChatGPT every day.

The James Webb Just Found Something Extremely Bizarre About the Mysterious Object Headed Into Our Inner Solar System

Our solar system's latest and only third known interstellar visitor is becoming more fascinating by the week. Spotted in early July, the object, dubbed 3I/ATLAS, is widely believed to be a comet.

Now, the James Webb Space Telescope has turned its mighty eye — specifically, its Near-Infrared Spectrogra

Charting Form Ds to roughly see the state of venture capital “fund” raising
