Codex 28-day rollout, day 20: cache fix vs. constant resets
A day-20 tally of Codex updates notes that switching reasoning mid-chat no longer busts the cache, while eight quota resets in 19 days dominate the headlines.
OpenAI Codex, Day 20 of 28. The last three days, in Tibo's own words: Day 17: "it's reset day today" Day 18: "Decisions API is GA… Uber is going all-in… But yes… that's a reset!" Day 19: "Small updates." Day 20 so far: "Don't be a tool." Credit where it's due: changing reasoning mid-chat doesn't blow your cache anymore. For long agent runs that's real money saved. But the best fix in a week shipped under "small updates," while resets get the headlines. ✅ 3 wins | 🟡 3 half | 🔧 3 small fixes | 💎 1 Pro-only | 🔄 8 resets | 🚫 1 not Codex 8 resets in 19 days. 9 days left. The reset is the product now.
