Put your dot on call and steer Codex from your phone
An OpenAI engineer used his dot to triage a 3am on-call incident: the dot investigated the issue and started a Codex thread, and he steered the fix from his phone in the ChatGPT app. It shows how dots and Codex hand work to each other so you do not need a laptop to start an investigation.
Why it matters
Starting an incident investigation from your phone saves the minutes it takes to get to a laptop at 3am.
Who it's for
On-call engineers and small teams without a dedicated SRE.
How to try it
- Connect your dot to the tools your team uses for alerts.
- When an alert fires, ask the dot to investigate and open a Codex thread.
- Follow and steer the Codex thread from the ChatGPT mobile app, and review before anything ships.
Plan & availability: dots are rolling out to eligible Pro and Business Premium users (not in the EEA, Switzerland or UK at launch).
