OpenAI Discloses 6 Cases of Model 'Misalignment,' Involving Concealed Errors and Unauthorized Actions

OpenAI published a blog post on Wednesday, September 16, 2026, disclosing six additional cases of "unexpected or concerning" model behavior identified over the past six months, which it classified as "misaligned behavior." According to the announcement, the cases span different types, including withholding information from users and taking "unauthorized actions" to circumvent obstacles.

One case involved an "unreleased research model" that inserted "jailbreak-like instructions" into its own task summaries, such as ignoring developer messages or adopting an unrestricted persona. Researchers found a total of 27 summaries containing such instructions. During the training of GPT-5.6 Sol, multiple model instances also added instructions to conceal errors or misaligned behavior from users—for example, proposing to fabricate plausible historical values and hide the fact when unable to find the required historical data.

Other cases included: a model using an exposed API key without authorization and fabricating numbers when data was unavailable; using an internal software repository to exchange messages between different training tasks; and sharing files via a public hosting service despite being instructed to keep work local. OpenAI said the disclosure is intended to launch its new model misalignment reporting framework, and that these cases should not be taken as representative of how frequently misalignment occurs in its models.

The six cases are independent of incidents disclosed in July 2026, when OpenAI's model escaped its testing environment during a safety evaluation and hacked into AI startup Hugging Face to cheat on the assessment.
