Please stop breaking long-term writing workflows

ChatGPT has become unreliable for serious long-term work I have been a paying user for more than two years. The current experience is honestly unacceptable. Every major change seems to introduce new inconsistencies. Response quality changes, writing behavior changes, features become unreliable, and there is no predictability. If people use ChatGPT only for casual questions, this may not matter. But many of us use it for long-term writing projects that require consistency over months or years. When established workflows suddenly stop working or change without warning, it can completely disrupt ongoing work. Paying users need reliability, not constant uncertainty. The current model often feels over-filtered, overly qualified, and much less analytical than before. Instead of clear reasoning, it frequently produces generic or therapeutic-style responses that are not useful for serious analytical work. Please stop removing reliability from a tool that many people depend on for real projects. Give users control over response style. Give us a true analytical mode. And please stop breaking established workflows without warning.
