With gpt5 I’m not sure this is true. Certainly openAI is still losing money but if they stopped research and just focused on productionizing inference use cases I think they’d be profitable.
I think it's relatively easy for Meta to plow billions into AI. Last quarter their revenue was something like $15 billion. Open AI will be lucky to generate that over the next year.
For a couple of years, until someone who did keep doing research pulled ahead a bit with a similarly good UI.
