OpenAI CEO Forced to Delay GPT-5 Launch: “It’s Harder Than We Thought”

OpenAI CEO Sam Altman announced a delay in the release of GPT-5, citing the need to improve it beyond initial expectations and address integration challenges. Instead, two new models, O3 and O4-mini, will be released in the coming weeks. The delay allows for refinement of GPT-5 and distribution of the training and deployment burden.
