OpenAI to Shut Down Custom GPTs Entirely by December, Angering Power Users

A Reddit user reports that OpenAI announced it is phasing out Custom GPTs starting this month, with a complete shutdown in December. The poster calls it one of OpenAI's worst decisions, describing Custom GPTs as ChatGPT's best feature and the entire reason they pay for it over Claude — they've built custom assistants for every project over considerable time. They speculate Projects might be a substitute or they may switch providers, and urge affected users to email OpenAI in protest, hoping to at least keep existing GPTs usable.
