OpenAI released GPT-5 on 7 August 2025. It was better at coding and reasoning and hallucinated less, but the leap felt smaller than GPT-3 to GPT-4, and the removal of older models from the interface caused enough complaint that they were restored. The reaction marked a shift in the debate from what scaling would achieve next to whether scaling alone was still the route.
