Hello,
Thank you for contacting OpenAI Support and for sharing your experience.
We understand that you have used ChatGPT for a long time and have recently noticed what feels like a meaningful decline in response quality or reasoning capability.
We reviewed the available information associated with your request. At this time, we do not see an active integrity enforcement associated with this issue.
This means the change in quality you are experiencing is not currently documented as the result of an account warning, deactivation, or policy-related restriction.
Regarding your request to return the account to its previous “normal effort/model” behavior, OpenAI Support does not have a manual switch that can restore an individual account to an earlier model state or permanently change the reasoning behavior assigned to that account.
Check your current model and reasoning settings
If you are on an eligible paid plan, please check the model picker and confirm which model and reasoning level you are using.
GPT-5.6 Sol supports selectable reasoning levels on eligible paid plans, including:
Instant
Medium
High
Extra High
You can also check Settings > General > Higher intelligence. Where available, this setting allows ChatGPT to automatically use additional reasoning for more complex requests even when Instant is selected.
Available models and reasoning options can vary by subscription plan and workspace settings.
If the quality difference continues
If you continue seeing noticeably weaker results while using the same model and reasoning configuration, please send us one or two specific recent examples showing:
the model selected;
the reasoning level selected;
the approximate date and time;
what you asked ChatGPT to do;
what you expected from the response; and
what was materially different or worse compared with the quality you previously received.
You may remove or redact any personal, confidential, or sensitive information.
Examples using the same model and settings are especially useful because they help distinguish a genuine change in model behavior from differences caused by model selection, reasoning level, conversation context, or other product settings.

Thank you for taking the time to report the change you have noticed. Based on the information currently available, we do not see evidence that your account has been intentionally limited because of a policy-related action.
Best regards,
