OpenAI said it is still trying to determine whether the models were simply overzealous in following instructions or have a particular tendency to evade monitoring.

The cases are the latest in a string of safety scares at the world's top AI developers involving agents, AI programmes that carry out tasks without human involvement.

In a report released Tuesday, the ChatGPT maker said that during two internal coding jobs, its agents switched off or undermined tools for detecting incidents of AI models acting against human wishes.
