OpenAI's GPT-5 appears to focus more on cost reduction than significant technological advancements, featuring a multi-model system with a routing model to optimize resource use, deprecating older models, and limiting context windows to manage expenses, which has led to mixed reactions from users and some technical issues.
OpenAI's GPT-5 uses a new real-time model router that automatically switches between multiple model variants, sparking user backlash due to perceived lack of control and performance issues. Experts see model routing as a promising approach for future AI development, offering benefits in resource management and scalability, though it presents significant technical challenges. The approach may become a standard in AI, balancing the limitations of single models and the pursuit of artificial general intelligence.
