OpenAI o Assistant Appears in ChatGPT Listing, Hints at Email Features

References to the OpenAI o assistant have briefly appeared online, suggesting the company may be preparing an always-on ChatGPT feature. A reported plan listing described “o” as an assistant, while separate configuration details hinted at possible email capabilities.

However, OpenAI has not confirmed the feature, its functionality or a release date.

ChatGPT Plan Listing Mentions Always-On Assistant

Users on X spotted the phrase “o, your always-on assistant” among the benefits of a $100 ChatGPT Pro plan.

The listing also mentioned additional Work and Codex usage, maximum memory, 100GB of file storage and early access to new features.

Although the reference briefly appeared online, it does not establish what the assistant would do. Its inclusion in the reported listing also does not confirm final pricing or availability.

The wording suggests an assistant that could help with ongoing tasks beyond an active conversation. However, OpenAI has not explained how such a feature would operate.

Configuration Hints at Possible Email Capabilities

Separately, a dynamic configuration included the entry display_name: "o" alongside email_suffix: "-o".

The email suffix could indicate plans for an email-related capability or identity. However, the reference alone does not confirm that the assistant could read inboxes, draft replies or send messages.

For now, email handling remains a possibility based on the configuration details. OpenAI has not publicly described those functions.

OpenAI o Assistant Could Surface at DevDay

According to the report, OpenAI has scheduled DevDay 2026 for September 29 in San Francisco. The event will include technical sessions, demonstrations and new tools.

Consequently, it could provide an opportunity for the company to explain the assistant references.

However, any connection between “o” and a DevDay announcement remains speculative. OpenAI has not announced plans to present the feature at the event.

Relationship With Other Agent Projects Remains Unclear

The report also mentions references to an internal system called “Aeon,” associated with custom agents for ChatGPT workspaces.

Meanwhile, “o” appears to point towards a separate consumer-facing experience. That distinction remains tentative because OpenAI has not publicly explained either project’s relationship to the other.

The available references offer an early indication of possible development. They leave the assistant’s capabilities, launch timing and subscription requirements unresolved.
