Code red at OpenAI as it 'pours money down a black hole'

fjo3 writes: Since its release in late 2022, OpenAI has become one of the world’s most valuable start-ups, raising tens of billions of dollars and making Sam Altman, its chief executive, one of Silicon Valley’s most prominent figures.

But even as it breaks records, OpenAI is facing questions about whether the vast sums investors have ploughed into the company will ever be repaid.

Some have even speculated that the poster child of the AI boom could run out of cash and potentially bring down much of the US tech sector with it.
