Speculation is mounting around **OpenAI**'s development of a new always-on assistant, tentatively named "o". While **OpenAI** has yet to officially confirm or deny its existence, brief mentions of the feature appeared online, sparking considerable interest. Users on X (formerly Twitter) noted that "o, your always-on assistant" was temporarily listed as a benefit for the $100 **ChatGPT Pro** plan. This inclusion suggests a premium-tier feature designed to offer continuous AI support.  The leaked details indicated that "o" would complement existing **ChatGPT Pro** benefits, such as increased **Work** and **Codex** usage, maximum memory, 100GB of file storage, and early access to new features. Further evidence emerged from a dynamic configuration, which included `display_name: "o"` and an `email_suffix: "-o"`. This suggests the assistant might eventually integrate email capabilities or possess a distinct digital identity, aligning with the concept of an "always-on" helper that can manage tasks even when users are not actively engaging with **ChatGPT**. ### DevDay 2026: The Potential Reveal **OpenAI** has confirmed its **DevDay 2026** event on September 29 in San Francisco. This platform is typically used to unveil new features, tools, and technical insights from **OpenAI**'s development teams. It would not be surprising if "o" makes its official debut or receives a more detailed explanation during **DevDay**. The event promises a closer look at the company's innovations, including technical sessions and demonstrations of new tools. While there have also been mentions of an internal "Aeon" system related to custom agents for **ChatGPT** workspaces, "o" appears to be a distinct, consumer-facing experience, signaling **OpenAI**'s push towards more ubiquitous AI integration.
