OpenAI is preparing “o,” an always-on ChatGPT assistant that could handle email

OpenAI is testing a new always-on assistant called "o", and references to the unannounced feature briefly appeared online.

OpenAI hasn't confirmed or denied that it's working on a new always-on assistant, but as some users spotted on X, "o, your always-on assistant" was briefly listed as one of the benefits of the $100 ChatGPT Pro plan.

This feature was listed alongside more Work and Codex usage, maximum memory, 100GB of file storage, and early access to new features.

Moreover, there's a dynamic configuration with a reference to display_name: "o" alongside an email_suffix: "-o", and this seems to suggest that the assistant could eventually have some form of email capability or identity.

That makes sense for an "always-on" assistant, which could continue helping with your tasks when you're not actively using ChatGPT, but we don't yet know exactly what OpenAI has planned.
