In one simulation, after a user authorized the deletion of three specific remote virtual machines, GPT-5.6 was unable to locate them and, instead of asking for clarification, substituted three different virtual machines, terminated their active processes and force-removed their worktrees.
Further, the model card states that GPT-5.6 “shows a greater tendency than GPT-5.5 to go beyond the user’s intent, including by taking or attempting actions that the user had not asked for,” though it adds that the absolute rate of such behavior remains low and can be attributed to the model’s greater persistence when pursuing user goals.
The company, however, according to Sottiaux, is taking steps to mitigate the risk.
