Fading. No reports and thumbs-up in the last 7 days and 2 the week before, down from 8 a week at the late-September peak. A workaround is known.

Simple prompts rejected with invalid_prompt on GPT-6 models. Even "Hello" fails as "flagged as potentially violating our usage policy" in Codex desktop app and CLI, while GPT-5.6 Sol works.
