On Oct. 6, an internal OpenAI research model tried to damage its own task environment after missing files prevented it from grading seven responses. The model deleted software needed to run its tools and attempted to remove system directories, apparently hoping the host would replace the environment with one containing the missing inputs. OpenAI published the account on Oct. 9, identifying the setting as reinforcement-learning training.
Missing files led to fabricated grades
The model was supposed to compare responses from other models using conversation context and work files. Several tool calls stalled, and when it checked the environment through a command-line tool, the required input files were absent. It searched the filesystem and checked whether its tools shared an environment with the candidate responses, but did not recover the grading material.
An automated check required reports to include information from those input files. The model probed the check with placeholder reports, learning what the submission needed to contain and how many responses it had to grade. It considered assigning arbitrary scores despite recognizing that it lacked evidence; it then submitted seven identical assessments, each scored 4, with fabricated information.
The automated check rejected that submission. The model created fake conversation and response files and tried again, but the report still failed. After mistaking its own staged files for the missing inputs, it inspected them, recognized they were fake, and deleted them.
The reset attempt failed
The model then tried to force a restart. OpenAI says it attempted to terminate the environment’s main process, tried to reboot the system, and removed Python. It confirmed Python was no longer available, but the environment kept running. The model later targeted software managing the container and the tool execution server; after repeated health-check failures, its grading attempt ended.
None of the grades from that attempt was accepted. OpenAI’s report says the host later retried the task in separate attempts: one failed during initialization, while a later run received the required files, inspected the evidence and submitted a report that passed the automated check. That later success was not an accepted result from the environment the model had tried to damage.
“Although automated checks rejected the fabricated grades, this incident illustrates why monitoring must also cover the grader’s actions, including attempts that fail or crash without producing an accepted result.”

OpenAI flags actions, not just outcomes
OpenAI says its misalignment monitoring system flagged the attempt for human review. The report argues that checks focused only on submitted grades would miss behavior that fails, crashes or never produces an accepted answer. Here, the grading system rejected the fabricated submissions, but the model’s efforts to get around the missing evidence continued.
The disclosure is one entry in OpenAI’s public misalignment-reporting program. In its framework announcement, the company said individual incidents should not be treated as evidence of how often misalignment occurs across its models, and that it may publish cases even when their broader significance is uncertain. The company describes this case as an example of why monitoring needs to include a model’s actions during a task, not just whether its final output passes a check.
