GPT-5 Launches Tomorrow – Why Thursday’s “LIVE5TREAM” Could Reshape the AI Stack

OpenAI is set to unveil GPT-5 tomorrow, with mounting evidence suggesting a significant leap in AI capabilities. CEO Sam Altman’s weekend selfie leak, featuring "ChatGPT 5" in the menubar, sparked early speculation. The head of applied research at OpenAI further fueled expectations with a Monday post expressing excitement about the public’s reception of GPT-5.

Microsoft’s Azure upgrade, involving months of GPU rack stockpiling, hints at GPT-5’s substantial computational demands. Altman’s July remarks on feeling "useless relative to the AI" during early testing underscore the model’s anticipated prowess. Tuesday’s announcement of gpt-oss, two open-weight models, was framed as a prelude to a more substantial release later in the week.

Polymarket odds now heavily favor a GPT-5 launch during tomorrow’s LIVE5TREAM. The upgrade is expected to deliver sharper reasoning, enhanced multimodal functionality, and an expanded context window, marking a pivotal moment in AI evolution.
