Hard Numbers: Scarlett Johansen’s voice on ChatGPT, Sony Music’s warning, Energy drain, Stability AI’s instability, Sharing the love — and the GPUs

2: Film star Scarlett Johanssonturned down OpenAI’s Sam Altman twice when he asked to use her voice for ChatGPT’s speech applications. She said no, but OpenAI has released a voice called “Sky” that sounds similar to Johansson. The actress (well, at least her voice) starred in the 2013 film “Her”— which Altman has called his favorite movie — portraying a disembodied AI that the protagonist becomes infatuated with. OpenAI says it hired another actress to voice “Sky,” but the company has now removed the voice “out of respect for Ms. Johansson.”

700: Sony Music sent letters to 700 AI developers and music streaming companies telling them it’s “opting out” of letting them use its content for training models. That includes musical compositions as well as lyrics, recordings, music videos, and album artwork. Last year, AI-generated songs featuring the fake voices of Drake and The Weeknd became a viral smash on social media — but music publishers aren’t in the habit of licensing their assets for free.

30: Microsoft reported that between 2020 and 2023 its energy emissions jumped 30%, a sign of the huge toll that artificial intelligence could take on the planet. Microsoft wants to be carbon negative by 2030, but its generative AI initiatives have hampered progress toward that goal.

1 billion: Amid a cash crunch, Stability AI is reportedly exploring a sale. The startup, which makes the Stable Diffusion image generator, was valued at $1 billion in 2022. The biggest question is who can buy it? The Biden administration has chilled the merger and acquisition market, taking an especially aggressive approach to litigating alleged antitrust allegations throughout Silicon Valley.
