2. ChatGPT Brings Think Reasoning Mode to Free and Go Users on Web

OpenAI. OpenAI extended its Think feature, which applies higher reasoning effort to complex questions, to Free and Go users on the web. The same release adds smoother dictation and composer behavior on Android and lets users switch an existing project between default and project-only memory without starting over. The changes bring more of ChatGPT’s reasoning and project controls to lower tiers. Source

3. OpenAI’s Computer History Turns Mac Activity Into ChatGPT Memory

OpenAI. OpenAI introduced Computer History, a feature that records a user’s clicks and keystrokes on Mac devices into a searchable timeline the assistant can draw on as memory. The captured activity is stored locally, and reporting noted the files are kept unencrypted, raising privacy questions about how the data is retained and protected. The feature extends ChatGPT’s memory beyond past conversations into a log of on-device activity. Source
