The added flexibility gave me more room for creative experimentation, too, as I wasn’t worried about running out of film. I also loved using the Instax Mini Evo app to print photos from my smartphone.

In what would be a major concession, Altman told employees that the government said it is willing to include OpenAI’s named “red lines” in the contract, such as not using AI to power autonomous weapons, conduct domestic mass surveillance, or engage in critical decision-making.
