Claims
- Mercury-alpha is widely suspected to be GPT-5.6, though a surprise same-day release appeared increasingly unlikely by the time of publication.
- OpenAI's Codex is evolving from a coding tool into a full agent workspace or 'work surface.'
- ChatGPT's new Library feature enables persistent memory of user files and work across sessions.
- Hermes Desktop from Nous Research positions itself as the open-source answer to proprietary desktop AI agents.
- Every major AI lab is moving directionally from 'chatbot' toward 'computer operator.'
Key quotes
The bigger shift: Codex is becoming a real work surface, ChatGPT is starting to remember more of your files and work through its new Library, Hermes Desktop from Nous Research is chasing the open-source desktop-agent version of the same idea, and every major AI lab seems to be moving from 'chatbot' toward 'computer operator.'
A surprise release feels less likely than it did this morning. But by noon PT (hopefully sooner!!), we should at least know whether OpenAI is shipping something today or whether the internet collectively stared at a codename until it started staring back.
