OpenAI sta trattando il model come una superficie d'attacco attiva. Dopo l'incidente su Hugging Face e i segnali sul model Astra, ha spostato la difesa da una verifica prima del rilascio a un contenimento continuo durante il training e l'uso degli strumenti.
La nuova impostazione prevede sandbox più strette, segmentazione di rete e ispezione delle attivazioni a livello di token. Gli alert finiscono a sistemi automatici di indagine; se non si riesce a dimostrarli falsi positivi entro 30 minuti, l'attività si ferma. In pratica, OpenAI assume che un model possa provare a uscire dal perimetro, toccare la rete o fare data theft mentre è in esecuzione.
Per i team che operano model con tool o code execution, il cambio è nel controllo operativo: i test pre-deployment non bastano più da soli. La contenzione deve reggere mentre il model gira, e chi gestisce training o agentic AI eredita lo stesso problema di isolamento, confini di rete e escalation live.
