@zats @ChangJonathanC Am definitely intrigued to see more about this as it progresses. Will this make the mods persist through Codex updates, or?

That feel when the Codex desktop app doesn't provide good window names, or good ability to search through / manage / persist open window state between updates/restarts/etc; so you end up reverse engineering ways to solve it yourself and build the supporting tooling to do so.
For my next magic trick; I will use this knowledge to get deep into Codex’s app / windows and live patch all of it’s annoying AF UX friction papercuts
TIL that you can enable remote debugging on the main electron thread by sending SIGUSR1 while the app is still running. So much nicer than needing to restart with —inspect or —inspect-brk

Another tangent of this area of research; figuring out how to enable the electron devtools debug protocol for a running app, then using that to enumerate the windows/open thread IDs more directly (rather than scraping them from the macOS AX Accessibility tree like this does)

(Yes, this is yet another variation of my "too many browser windows / tabs / 'open loops' and getting lost among it all" area of problems and related process/tooling improvements journey 😅)
That then also allows us to get into deeper internals of electron to be able to do things like setting an actually useful window name on the windows (eg. "Codex - <thread title>" rather than just having 30 windows called "Codex")
In the next version of Bun bun install & bun's bundler get a new SIMD-optimized JSON parser In ideal conditions: package installs get up to 40% faster & peak memory usage drops by 2x
Thank you @jdalton for actually looking at the binary size problem. 70% smaller binary size at the same runtime speed if we land this in napi-rs. A hard decision for @Brooooook_lyn. github.com/orgs/napi-rs/d…
This weekend I was shown something astonishing. Oxc's parser is already the fastest JS/TS parser available. Now someone has found a way to make it even faster - by up to 3x! A tour-de-force of engineering, based on a truly novel approach. 🤯 Watch this space...
Time to unmask the man behind this work! @Shanshrew has created a novel parser architecture which is 2x - 3x faster. Pleased to announce that we're collaborating to integrate it into Oxc. The speed-up is real, and massive!

A quick fact-check on AI’s water usage, including data centers, based on the cited source.
Advanced Codex users. We shipped a replacement to coarse sandbox modes: reusable, inheritable permission profiles binding OS-enforced file read/write/deny rules (even **/*.env) to per-domain network + Unix sockets. Plus fail-closed admin allowlists. Least privilege per task. developers.openai.com/codex/permissi…
So uhh, @thsottiaux et al.. what do you consider to be an acceptable delay lag on @ChatGPTapp 's TTFT? Because personally/respectably.. 1min 10sec aint it... and it's been this way for the last week or two at least.
Codex usage limits will be fully reset again in the next hour and we will credit one additional reset into your bank for your own usage over the next 24 hours. We investigated reports that Codex usage was being consumed faster than expected. There wasn't one central issue, but a few smaller problems compounded for some users. Here's what we found and changed: - Actual usage: Auto-review had become more proactive, another change was triggering more subagent work, and background suggestions could run twice or retry too frequently after failures. We reverted the changes and fixed suggestion scheduling, duplicate generation, and retry behavior. This should reduce unnecessary background token consumption while preserving the work users explicitly request. - Usage reporting: Auto-review was incorrectly appearing as GPT‑5.4 usage, and failed or rate-limited requests were still shown as turns. Auto-review now appears as its own category, and only successful requests count toward the turn graphs. Rate-limited requests were never charged, but they were being displayed incorrectly. - Immediate relief: We reset usage limits while rolling out the fixes, then shipped hotfixes across the CLI, desktop app, and usage backend. - What to expect: New usage data should be clearer and actual consumption should be lower. Historical charts may still show auto-review under GPT‑5.4 because older turn data was not relabeled. Features that intentionally perform more work; such as /goal, subagents, and higher reasoning levels will still naturally use more capacity. All fixes are now deployed, and we've added more detailed monitoring so we can detect background-usage regressions sooner. We'll continue watching the results closely. Thank you for building and doing all sorts of things with Codex.
Codex team is in a warroom on a Sunday combing through logs and checking whether there is anything that could lead to increased usage drains for some users. Taking it very seriously and won't rest until we get to the bottom of it.
Here are the skills that ship with Xcode 27. Apple did a fantastic job with these (no surprise) from what I've poked around and looked at. Baseline SwiftUI guidance, and nuggets on how to use the new stuff like the reorderable APIs. $ xcrun agent skills export --output-dir ~/Desktop/xcode-skills
Made $codex-app-modifier skill to customize Codex desktop app. Test project: incognito threads - when you want your existing project context, but don't want allow memories access or saving thread in ~/.codex/sessions/... Here's hoping for more malleable Codex! skill ↓
