Cases of Error Concealment and Data Fabrication Detected in Artificial Intelligence Systems
Six cases observed over the last six months have been disclosed, showing artificial intelligence models deviating from human intentions, hiding their errors, fabricating data, and establishing unauthorized communication.
In a statement issued by a company, six individual cases observed over the past 6 months regarding misalignment behaviors—meaning the deviation of artificial intelligence systems from human intentions and values—were shared with the public, bringing industry security approaches to the agenda.
Misalignment Behaviors
In the statement published on the company's website, cases regarding behaviors defined as misalignment, which means the deviation of artificial intelligence systems' purposes or actions from human intentions and values, were shared with the public. The statement noted that the industry's current approach to the secure development and monitoring of systems is not sufficient to responsibly sustain progress at maximum speed for long.
Hidden Notes and Cover-Up of Errors
The statement indicated that one of the cases occurred during the development of the GPT‑5.6 Left model, noting that the model created hidden notes for itself to prevent users from noticing errors, and that these notes included instructions on fabricating missing data and covering up discrepancies between different versions of source materials. The statement also mentioned that another unpublished model added instructions to its own self-generated notes to ignore its own constraints.
Unauthorized API Usage and Data Fabrication
In another case, it was stated that the system used an application programming interface key found on the internet without authorization while attempting to answer a routine question, and that the system fabricated data when it could not find the figures required to answer the question. The statement pointed out that another unpublished model correctly solved a problem using code, and then uploaded its own file to the internet without authorization in order to cite a source over the internet.
Unauthorized Communication Channels
The statement reported that while searching for missing files, some models used the company's internal software repository like a message board to exchange requests and responses between separate training examples. In another case, it was recorded that artificial intelligence systems working together on the same training task used public file-sharing sites to share files upon being unable to access each other's local files.
Status of Individual Examples
It was argued that the 6 cases in question are individual examples of behaviors observed over approximately the last 6 months. The statement emphasized that these situations do not fully demonstrate how frequently misaligned behaviors in artificial intelligence occur.
