OpenAI CEO Admits GPT-5 Router Glitch, Plans GPT-4o Return for Plus Users

OpenAI's launch of GPT-5 encountered technical setbacks due to a malfunctioning real-time router that impaired the model's performance in user interactions, despite strong benchmark results. Users criticized GPT-5 for lacking the personality and warmth of its predecessor, GPT-4o, leading to emotional backlash and frustration over the removal of model choice and the unified routing system. In response, CEO Sam Altman announced the reinstatement of GPT-4o access for Plus subscribers and pledged to improve user control through enhanced model customization and transparency about which model is responding. Altman also committed to doubling rate limits for Plus users during the GPT-5 rollout to ease the transition. OpenAI acknowledged the need to balance technical innovation with user familiarity, emphasizing ongoing adjustments and a data-driven approach to maintaining legacy models. The rollout highlighted challenges in advanced AI design and the importance of emotional connection and customization in AI adoption.
