Overview

• GPT-5 is in final testing, integrating GPT-series speed with o-series reasoning into one unified system that automatically selects the appropriate engine per prompt.
• Lightweight mini and nano GPT-5 variants are being prepared for API release to broaden access for free and paid users.
• Microsoft has begun internal trials of Copilot’s new Smart Mode, which dynamically switches between fast or deep-thinking engines based on user queries.
• OpenAI CEO Sam Altman said testing GPT-5 left him feeling “useless,” likening its development pace to the Manhattan Project and warning of gaps in AI governance.
• The model’s early benchmark sightings and public teasers set the stage for an official rollout expected in the first week of August.
