UltraFast is 8x faster at 6x the cost. That means you’re burning through your money 48x faster while it’s running. 8x faster token generation × 6x higher cost per token = 48x higher spending per second. You’re paying 6x more overall to finish 8x faster.

28 Days of Codex // Day 15 Day 15 is a "we're cooked" livestream post. 0/10 A broadcast is not a ship. Users got a vibe, not a feature, a fix, or a reset. Day 15 of 28 and the promise is running on fumes. I really hope this is a part one…

28 Days of Codex // Day 14 You can now edit previous messages in the desktop app. 5/10 Useful every day, and long requested, so fixing a typo no longer means living with it forever. Good ship. It only took forever, by his own admission.

28 Days of Codex // Day 13 Day 13 is a full limit reset, landed hours early. 9/10 The fallback is doing a lot of heavy lifting in this series.

The absolute best vibe coding combo you can get right now is $100 Claude $20 Codex Codex for strictly checking Opus 5.5’s work This $120 combo can be switched around if OpenAI ever comes out with a better model

There has been no commits to photocraft for 12 hours... Looks like its been abandoned @get_artcraft

28 Days of Codex // Day 11 Capacity errors get rarer, and stop blocking when they hit. 7/10 Fewer dead ends mid-task is real relief for anyone who actually uses Codex daily. Now to is if it prove holds at peak hours…

I have 100% conviction Adobe stock is headed to extreme lows… These market makers can hold it up for a while, but that will fatigue It’s larger direction will be headed down

28 Days of Codex // Day 9 Desktop app now stores 60% less on disk. 4/10 Real relief if you were running out of space. For everyone else, nothing visibly changed. A tidy cleanup, not an impactful ship. More like a filler improvement..

The thing I love most about Muse Wonder is the nostalgia... It's refreshing to see how ChatGPT was when it first came out Breathe of fresh air...

28 Days of Codex // Day 8 Day 8 was a global reset, landing by end of day. 9/10 Always a 9 in my book..

28 Days of Codex // Day 7 GPT-6.1 Sol default context in Codex and Work is now 500k, up from 272k. 6/10 Nearly double the room before compaction, and no long context fees on subscription usage. A settings bump, not a new trick, but everyone feels this one daily.
127
28 Days of Codex // Day 6 No ship today. A global usage reset instead, promised by end of day. 9/10 by default
128
28 Days of Codex // Day 5 Composer predictions in the Codex app, plus dots on mobile. 5/10 Predictions are handy and cost no usage. Dots are ChatGPT housekeeping in a Codex badge. A light day. No reset, no core capability, just garnish.
150
28 Days of Codex // Day 4 Instant steering and GPT-6.1 Sol Ultrafast, up to 8x faster in Codex. 7/10 Definitely useful. The model course-corrects in real time now instead of confidently finishing the wrong thing. More speed, same engine. Still no reset.

Codex Reset Paradox: Imagine you get a free tank of gas every Friday. On Wednesday, the gas station announces a surprise free refill. If you’re on empty, that’s amazing. If your tank is 90% full, you barely get anything. Oh, and your Friday refill is canceled.

28 Days of Codex // Day 3 They gave everyone access to GPT 6 more of an unlock than a feature but still good nonetheless On its own: 6/10. But we got a reset so 9/10
