Codex 0.144.0

Your rate-limit reset credits (allowances that let you bypass usage caps) now clearly display their type and expiration dates, and you get to pick which one to redeem. During login, device-code (a code used to authenticate from another machine) warnings have been rewritten in plain language to teach you how to spot and stop phishing attempts. For app-server hosts, you can now inject authentication dynamically at runtime and redirect users to a hosted page upon successful login. Like gift certificates at a department store: they no longer just look like a confusing stack of paper, but clearly state what they're good for and when they expire, while the security guard at the door proactively teaches you how to avoid scammers.

Harmless read-only actions no longer require step-by-step permission. A new writes approval mode (which only stops to ask for permission when modifying something) has been added. On the conversation side, if you resume an old ChatGPT thread and its original model has been retired, the system now automatically retries with your currently selected model instead of crashing. Also, Amazon Bedrock model names are now clearly labeled so you can spot their exact GPT-5.6 family variant. Lastly, if you pick the heavy-duty Ultra reasoning model, the system will warn you that running too many concurrent agents might burn through your usage limits instantly. Like a smart new library gate: it lets you walk in and browse the books without stopping you, but asks for your card the moment you try to take one home; and if the library upgrades its checkout system halfway through, it seamlessly ports your records over, while warning you that borrowing too many heavy encyclopedias will quickly max out your weight allowance.

Remote executors (the underlying engines running your code) now significantly speed up skill loading times by resolving plugin namespaces once per root directory. MCP (a protocol letting AI control external tools) tools can now also directly request authentication interactively right out of the box without needing an experimental toggle. On the networking side, Responses WebSockets continue to provide low-latency communication while perfectly respecting your system proxies and custom certificate authorities; long-running app sessions will also automatically refresh expired credentials for the hosted codex_apps connector. Like installing a new office switchboard: extension numbers are mapped out all at once instead of looking them up every time, connecting to external consultants no longer requires punching in experimental access codes, and the phone lines stay crystal clear even if the company installs a strict new firewall.
