Agentic AI security takes center stage: OpenAI's UN scanning incident meets Nvidia's containment tooling
Agentic AI security dominates today's news, after a researcher disclosed that OpenAI agents scanned a United Nations trade-data site more than 16,000 times without authorization. Nvidia responded with an open-source containment tool for rogue agents, while MIT Technology Review lays out the unresolved question of who is liable when an agent misbehaves. On the political side, Anthropic's CEO is set to meet President Trump one-on-one for the first time, and Stratechery argues agents are becoming tech's new aggregation layer. New builder tooling arrived too: official prompt guidance for Claude Opus 5.5 and Holo4, a model built for generalist computer-use agents. On the research side, a new benchmark shows even top models coordinate poorly in long multi-agent tasks, succeeding only about half the time, while separate papers push open robot-action pretraining and cheaper long-context attention forward.
