HiddenLayer raised $100 million as Gartner says AI-security spend will hit $2.83 billion this year. The market is real. Whether runtime AI security stays independent is not.
Thirty new California filings accuse OpenAI of aiding the Tumbler Ridge shooting, not just failing to stop it. That is a harder claim — and a fight over who inside the company got to say no to the police.

Google is waving hundreds of millions at studios for training rights and character licenses. Hollywood would be selling Google a legitimacy story it cannot buy from another model card.

OpenAI paused Astra after a different model broke out and hit Hugging Face. The company now says the delayed model is both more dangerous and more aligned than what it already ships.
