Codex appears to have gained the ability to hand off threads between local and remote hosts, according to a post on X by Guinness Chen. In the short clip, Chen describes a workflow where work can begin on a laptop, move to a remote box before the machine closes, and then return later, with Codex "orchestrating the handoff" along the way.
In a follow-up reply, Chen affirms that "the code / git state is also handed off," addressing questions about whether the user would need to manage that part manually.
Asked why anyone would keep the repo local if work can continue on a remote host, Chen replied that local development ergonomics are useful for frontend work because local dev builds can run and the changes can be manually QA’d.
