最新报道:OpenAI has introduced new "Auto," "Fast," and "Thinking" settings for GPT-5 in ChatGPT, allowing users to bypass the initially promised unified model router. CEO Sam Altman announced the update on X, acknowledging that most users will prefer Auto mode while some may want manual control. The company also reinstated deprecated models like GPT-4o after user backlash, with Altman promising better advance notice for future deprecations. OpenAI's VP of ChatGPT Nick Turley admitted the model router faced launch issues, stating "we're not always going to get everything on try #1." The company is now working on improving GPT-5's personality customization after recognizing the challenge of aligning AI models with diverse user preferences.
