With the introduction of plugins, Codex has become more practical, supporting planning, research, and coordination before writing code, as well as subsequent workflows. For example, if you install the Google Drive plugin, you can integrate a series of workflows across Google Drive, Google Docs, Google Sheets, and Slides into a single loop.

Jason Liu, a developer at OpenAI, says he uses approximately 58 automation features and 30 plugins, and that everything except coming up with ideas and talking to other people is automated.
I've been using plug-ins a ton internally. I have about 58 automations and 30 plug-ins and I've automated everything except the part where I have to come up with ideas and talk to people https://t.co/M69OiYmIjm

According to Alexander Enbilikos of the Codex team, Codex has completely transformed the way everyone at OpenAI works, and not only the technical teams, who use it in every aspect of their work, but also administrative and sales departments have optimized for Codex.
Over the past months Codex has completely taken over how everyone works at @OpenAI .

Technical teams use it for literally everything, and now that it's easy to plug into all our tools, even non-technical teams like comms and sales are codexmaxing. Much more to come! https://t.co/6hcyRn2niW
Tibo, also from the Codex team, stated that they reset the Codex usage restrictions in order to allow as many people as possible to use the plugins they released.
Hello. We have reset Codex usage limits across all plans to let everyone experiment with the magnificent plugins we just launched, and because it had been a while!
