Codex just shipped a new update.
And quietly ended the AI browser wars.
You can now save logins inside Codex's native internal browser.
Sounds small.
⤷ It's not.
AI browsers already worked on logged-in sites.
That was never the problem.
The problem was that they were a SEPARATE thing.
Another app.
Another window.
Another tab to babysit.
Your agent lived in one place and your browser lived in another and you spent your day shuffling between them.
Codex just collapsed that.
Now the agent and the logged-in browser live in the same app.
Your sessions are saved right where the work happens. The thing writing your code can also operate your logged-in web → without you opening anything else.
That's the whole game.
You don't need a dedicated AI browser sitting alongside your dev tool anymore. You don't need to context-switch between "the thing that thinks" and "the thing that browses."
One app.
Logins saved.
Agent working in-app on the sites that matter.
Every standalone AI browser just became a feature Codex absorbed.
The winners in this next phase won't be the ones with the most tools. They'll be the ones running everything from one.
If your workflow still needs a separate browser bolted onto your agent → you're carrying a tab you no longer need.
