Brief

A developer (shared by @chddaniel on 2026-05-10) dumped a two-week sprint into Codex 5.5 High with full permissions after reaching ~1% Plus-plan quota, ordered it to complete everything, and left it running. Nine hours later Codex had finished 4/5 deployment tickets with runnable, clean code and handled edge cases, prompting the developer to call it autonomous execution.

Why it matters

Reported by @chddaniel on 2026-05-10: a developer hit ~1% quota left on the Plus plan, pasted their entire remaining two-week sprint (deployment tickets) into Codex 5.5 High, granted it full permissions, and instructed it: "DO NOT STOP UNTIL YOU ACHIEVE ALL OF THIS."

Key details

  • After ~9 hours unattended, Codex completed 4 of 5 deployment tickets; the code ran, logic was clean, edge cases were handled, and deployments were not broken — leaving "barely anything to nitpick" on review.
  • The developer said the result felt like "actual autonomous execution" rather than autocomplete or a copilot, and that experience changed how he thinks about work going forward.

THIS GUY DUMPED HIS ENTIRE 2-WEEK SPRINT INTO CODEX AT 1% USAGE LEFT

he was basically out of quota on the Plus plan

so before going to sleep he said screw it, pasted every remaining deployment ticket into Codex 5.5 High, gave it full permissions, and told it:

“DO NOT STOP UNTIL YOU ACHIEVE ALL OF THIS”

fully expecting to wake up to the usual AI mess

broken deployments
half-finished logic
random hacks duct-taped together
hours of cleanup

instead he wakes up 9 HOURS LATER

and codex is STILL WORKING

not frozen
not looping
not asking for confirmation every 3 minutes

actually finishing the sprint

4 out of 5 deployment tickets done
code runs
logic clean
edge cases handled
deployments not broken

he literally said he started reviewing the tickets EXPECTING the usual AI cleanup

and there was barely anything to nitpick

that’s the part that messed with his head

this wasn’t:
“AI helped me code faster”

it felt like somebody did his job while he was asleep

his words:
“this kinda changed how I think about work going forward”

because for the first time

this didn’t feel like autocomplete
it didn’t feel like a copilot

it felt like actual autonomous execution

we’ve all joked that “software is cooked”

but this is the first time it stopped feeling like a meme
