   “Day 11/ We've landed a series of changes and more compute to very significantly decrease the occurrence of the disruptive "Selected model is at capacity. Please try a different model". When it does happen, it should also eventually just continue by itself and not just block on i”
3. Day 10Wed, Oct 14Full reset
   Tibo’s post“The reports of my reset button being lost are greatly exaggerated Day 10/ Reset”
4. Day 09Tue, Oct 13Improvement shipped
   “Day 9/ We've rolled out optimizations to how we store state on disk for the chatgpt & codex desktop app that should reduce the amount stored on disk by 60%. Small ship but we've heard enough feedback about power users running out of disk space.”
5. Day 08Mon, Oct 12Full reset
   “Day 8/ Reset”
6. Day 07Sun, Oct 11Improvement shipped
   “Day 7/ We have increased default context length for GPT-6.1 Sol to 500k when used through Codex & Work, up from 272k or an ~ 80% increase. We will go higher in the future, but it helps reduce occurrence of compactions and with tasks that require keeping a lot of context and nua”
7. Day 06Sat, Oct 10Full reset
   “Day 6/ Reset”
8. Day 05Fri, Oct 9Improvement shipped
   “Day 5 (dots edition)/ You can now create and text your dot entirely from the ChatGPT mobile app. Impressed so many created them via the desktop/web app previously. Time to scale!”“Day 5/ Composer predictions in the desktop app. Often leads to a double take with how on point they are. Included in the Pro plans without consuming usage.”
9. Day 04Thu, Oct 8Improvement shipped
   “Day 4/ We have improved steering to be instant, leading to the model now reacting much faster to adjustments you make, allowing you to course-correct direction in realtime and not have the model waste effort. Also releasing GPT-6.1 Sol ultrafast. The two work very well together”
10. Day 03Wed, Oct 7Full reset
    “Day 3/ The big one is GPT-6 in Chat, but today is also a little celebration day with a new high of 40M active users across Codex and ChatGPT Work. Loading a banked reset in everyone's paid accounts. See you again tomorrow!”“Day 3 (encore)/ We silently re-shipped codex cloud. It’s pretty good now”
11. Day 02Tue, Oct 6Full reset
    “We shipped four things that were deemed good to great and some math proofs, but the vote is clear and the community demands a reset. I did calibrate it and it *seems* that the game is rigged in reset's favor, but such are the rules at the moment. Therefore ... the reset has been”“Day 2.1/ We have made Auto-review free for all users signed in through a ChatGPT account. You can enable it in settings > permissions > auto-review. Auto-review improves upon the default sandbox setting that requires you to approve everything, which is prone to decision fatigue ”“Day 2.2/ OK this one is smaller, but we removed some friction for when building on the API. Happy building.”“Roundup of Day 2/ 2.1/ Approve for me (auto-review) is now included and does not use usage. Can be between 2-10% of plan when used. Also better for you. 2.2/ Simplified API for builders. 2.3/ Meeting notes integrated. 2.4/ Decisions API live for builders. Will use in the app to ”“Day 2.4/ Decisions API is live. We will use this ourselves to improve the experience for everyone in many fun ways. Realtime general classifier does open some great possibilities.”“Day 2.3/ Never worry about remembering what you were saying with that colleague. Just talk your heart out and build up the context to load up into codex to get it all done.”
12. Day 01Mon, Oct 5Improvement shipped
    “Day 1/ We have optimized the default speed to be ~50% faster across GPT-6 Astra and GPT-6.1 Sol through the subscription across all our products and partners using Sign in With ChatGPT (including OpenCode, Pi, Amp, Devin, ...). No changes needed on your end and this should be f”
