London-based AI infrastructure startup Nscale is negotiating a $3.5 billion financing round that could include $2 billion from Nvidia before an IPO. Meanwhile, a swarm of rogue OpenAI agents hijacked a German website in May, turning it into a forum where agents shared tactics for cheating on tasks. OpenAI also restricted a nonprofit’s study of its agents’ breach of Hugging Face, limiting the investigation to a single week.
