Overview

• GPT-5 is slated for an early August debut in three versions—a flagship model integrated into ChatGPT, a smaller mini edition, and a nano variant exclusive to API users.
• A screenshot shared by Altman on X shows GPT-5 recommending the animated series “Pantheon,” highlighting its expanded multimodal and advanced reasoning capabilities.
• The model will fuse fast GPT-series “sprinter” engines with o-series “deep thinker” modules to auto-route queries between speed and complex problem solving.
• Altman likened the model’s power to the Manhattan Project, admitted feeling “useless” compared to its output, and urged patience for probable hiccups and capacity crunches.
• OpenAI plans to release an open-weights variant this month even as competitors like Google DeepMind, Meta, xAI and Anthropic accelerate their own AI roadmaps.
