I’m a ChatGPT Plus user with a persistent Deep Research failure documented since June 2026.
Deep Research repeatedly completes with 0 searches / 0 citations across unrelated topics, browsers, devices, and networks.
The strongest control test: on the same physical computer and same browser, another paid Plus account completed Deep Research normally with approximately 500 searches and 19 citations, while my affected account continued to return 0/0.
OpenAI Support already has the relevant diagnostics, including a sanitized HAR, video reproduction, screenshots, timestamps, cross-topic tests, and conversation URLs.
The issue has remained unresolved for approximately three months despite extensive troubleshooting and multiple support interactions.
@OpenAI_Support — could you please review Case #15420179 internally and confirm whether it has reached the appropriate product/engineering owner?
I am intentionally not posting private account, billing, HAR, or personal data publicly.
